I am definitely going to do this soon. Thank you.

Does everything look right? There's also a little blinking line at the top left of the screen when it boots. My pc specs since i forgot to add them: AMD FX-6300 Six-Core (3.50 GHz) Asus M5A97 Motherboard Western Digital Caviar Black 500GB (boot drive, windows 10 home 64 bit)

Hi, This post is about converting my boot drive from MBR to GPT so that I could boot in UEFI mode. After doing the conversion (with MBR2GPT.exe) I had trouble booting and I couldn't figure out how to fix it in Windows PE, I messed around in the BIOS and got my PC to boot but now it shows 'Windows Boot Manager' in the boot priority. Is this just a problem with how the partitions are arranged? Any help would be much appreciated, I really don't understand what I'm doing. This shows the boot priority: Windows Boot Manager with the UEFI icon, followed by my HDD and disk drive (empty) without UEFI icon. I can provide a screenshot of my partitions if necessary.

Thank you for responding. I wish I had another GPU to try, but unfortunately I don't have any spare parts right now. If anyone has some recommendations on what GPU I should get as a replacement please let me know - I could really use some advice. Take a look at my PC specs to see what might work. I'm not really worried about my CPU causing bottlenecking if I upgrade my GPU, because I could just reuse the new GPU in a future build. Additionally, if anyone has recommendations on more comprehensive diagnostics I could run, please post here. As far as I can tell, my motherboard does not have an on-board graphics adapter that I can plug directly into - as I have seen some motherboards that do. This makes troubleshooting slightly more difficult for me. I've also considered that it could be a problem with windows and/or my boot drive. Should I look into getting a new drive and installing windows onto that and booting from it to see if the problem persists? If so, should I just buy another samsung 860 evo ssd? I'm running out of options here and I may just take it to a PC repair place to see if they can fix it for me.

Alright, I started my PC with the other monitor plugged in - with a different cable - and still saw the issue, in BIOS and after logging into windows. And to confirm that monitor was running 1600x900. I restarted again and went back to the original monitor. The image below shows what I'm currently using. Is it possible that my PSU is not working correctly and my GPU isn't getting enough power? I don't know enough about wattage, or really anything about hardware, but if my PC can display video and streams and things like that, then it would seem like a software issue. I know its a lot of text in my second post but I tried to explain how this could have happened. Aside from unplugging and plugging components in, I don't know how to test for deeper issues in the memory, or in the GPU or HDD. If it turns out its one of those things, replacement wouldn't be too bad. Hopefully it's not the motherboard because I don't want to have to do a full tear down.

I do have another monitor and another cable to try with. The monitor I'm currently on is 1920x1080, the other is 1600x900 I believe. I will try turning off my PC and plugging in the other monitor, then turning it back on and seeing if the BIOS still has weird graphical issues.

Apologies for massive wall of text incoming Additional information: As I stated in the original post, these problems began on Tuesday, October 1st. Prior to this, my computer had been running fine with no major problem for several months. The last change to hardware was back in July or August when I added the Samsung SSD, so that I could download some larger games (Destiny 2, Black Desert Online, Guild Wars 2). Recently however I have been mostly just playing World of Warcraft Classic. On Tuesday, October 1st in the evening I started up my PC as normal and was playing Classic with some google chrome tabs running in the background as well as discord. After some time playing - a couple hours perhaps - I put Classic in the background (running in windowed mode) and paused the chrome tab that was playing a video. Then I left the room. When I returned, my PC was on the windows login screen. I figured my PC had got a blue screen somehow, or that maybe my brother accidentally hit the power button on my PC. I thought nothing of it, and logged back into windows, reopened my chrome tabs (notification that chrome had crashed - clicked restore tabs), reopened discord and Classic and resumed playing. After some more time playing - perhaps another hour or so - my entire house lost power, as well as the house across the street. I could see all their lights flash off and on as well. The power outage was very short, less than a second. Probably a tree hitting a power line somewhere because it was quite windy. Again I went through the same steps, PC and everything started as normal. I played for a couple hours before switching to Guild Wars 2 to play with a friend. I played Guild Wars 2 for a couple hours as well before we decided to stop playing. At this point I think it was around 11:40 PM I switched back to WoW classic and played for about an hour or so before the real problems started. I was about to close everything and sleep when all of a sudden my monitor turned completely green, something I have never seen before. I could still hear audio from WoW as well as the chrome tab playing video. After about 10 seconds the sound stopped working as well, it sounded like it usually does when there is a crash, so I figured my PC would not recover on its own. I pressed the restart button on the front of my case and waited for it to restart. After it got to the windows login screen I clicked shutdown and went to sleep. Next morning on Wednesday, October 2nd, I turned on my PC as normal and everything seemed fine once again. I opened chrome and discord to listen to some music and watch videos while checking messages. After some time I started WoW Classic to play for a bit This time after about 45 minutes my whole screen turned orange, again with audio playing for several seconds before it started to sound like my PC was crashing (stuttering repetitive sound coming through the headphones). I pressed the restart button on the front of my case again and waited. However, this time the windows login screen never showed. Just a black screen after the windows startup graphic. I left my PC for roughly 20 minutes and when I came back it was still a black screen, so I pressed the restart button again. This time the windows startup repair launched and said 'there was a problem starting your PC' so I let it run, hoping it would fix something. After the startup repair finished, I clicked 'finish' and it restarted my PC. Again, the windows login screen never showed. Same black screen, waited for 10 minutes, pressed the button on my case to restart. Startup repair came up again, I let it run, it asked to restore the system to an earlier time, I clicked 'Okay' Startup repair said it couldn't find a problem. I believe it ran startup repair a second time before it restarted my PC. Again, windows startup graphic shows, then black screen. I pressed the restart button on my case again. Windows startup repair gives the same message 'there was a problem starting your PC', this time I clicked cancel, went to additional options and opened the command prompt. I used the command prompt to force my PC only to start in safe mode, then clicked restart at the bottom of windows startup repair. After the windows startup graphic showed, I was able to finally see the windows login screen (in low resolution of course). I logged in and let my PC just sit in safe mode for at least an hour to see if anything happened. I ran windows defender and let it scan but it didn't find anything I used command prompt to turn off automatic safe mode and then restarted to see if anything changed. Black screen again of course. Restart button, back to windows startup repair, clicked cancel, opened command prompt, back to safe mode. Safe mode started fine again. Opened command prompt, set it to start safe mode with networking, opened start menu and clicked restart. Safe mode with networking started fine. I let my PC run for a few hours in safe mode with networking, no issues. Figured it was a driver problem so I uninstalled my driver using the AMD cleanup utility because it wouldn't uninstall from the 'programs and features' for some reason. Deleted everything in C:\AMD. Downloaded the latest driver and installed it, restarted PC in normal mode and black screen. Retraced my steps back to safe mode and uninstalled GPU driver again. This time I just decided to see what would happen with no driver, and to my surprise windows actually started in normal mode finally. However it did seem like it took longer than usual - like a couple minutes instead of the usual 30 seconds it took before all these problems started. Oh well, I figured it was probably a side effect of having no GPU driver. In normal mode, I downloaded all the latest important windows updates and let it restart my PC as many times as it needed to finish. I got the latest version of Malwarebytes and let it scan, it found nothing. I let Microsoft Security Essentials run a quick scan and then a full scan, still nothing. I installed the 'recommended' driver for my GPU from windows update and let my PC restart. Black screen again. Windows startup repair restored to a previous point. Went back to safe mode to make sure I had no drivers. Restarted in normal mode and it starts. Ran a chkdsk in command prompt and it didn't find anything. Downloaded and installed the latest AMD driver, black screen after restart. Retraced my steps. Booted PC in normal mode to make sure it worked again, then shut it down. Unplugged the power from the back, moved GPU to the other PCIe slot and switched the PCIe cable connected to the PSU. Plugged it back in, turned it on to make sure it worked. Installed the latest GPU driver from AMD, black screen after restart, etc. Tried using an older GPU driver from July of this year, same thing. Ran disk defragmenter in windows because it said my C drive was at 10% fragmented. Didn't really seem to change anything. Opened Battlenet to see if my WoW Classic was corrupted or something, clicked scan and repair but it showed nothing was wrong. Tried to launch WoW to see what would happen, but it said my driver was not supported (of course). I can watch videos and streams on chrome with seemingly no issue, aside from the ones listed in the original post (colored lines and monitor losing signal). I've let my PC run for several hours in normal mode over the last couple days and it hasn't crashed. Alright, that's about all I can remember off the top of my head. This is my gaming PC so I don't really have important files saved on here aside from game save files. Nothing too critical. If I remember any other details about what happened I will update. All of this is just so confusing because I haven't changed anything for weeks, aside from downloading a few WoW addons. Is this from the power outage, or something entirely different? It seems rather delayed if that's the case. Otherwise this is a sudden problem out of nowhere. P.S. Forgot to mention I ran dxdiag64 of course. It shows everything working properly. So does device manager. Although it does say I am using VGA graphics even though my GPU is plugged into the monitor with a DVI cable. Could some of these errors just be side effects from not having a GPU driver installed? I can provide screenshots of anything necessary.

Since last week, Tuesday, October 1st; I've been having problems with my GPU (or possibly something else). Here's what I'm experiencing: It is not possible for me to install any GPU driver, all I can do is use 'Standard VGA Graphics Adapter'. If I install a GPU driver - either through windows update or directly from the AMD website - my computer will not be able to start windows. It will show the BIOS screen briefly - less than a second - then it will show the windows 7 loading graphic for a while, and then the screen will just go black. The monitor is on and detecting input but no action can be taken. All I can do from there is press the restart button on the front of my PC and use windows startup repair to restore the system to an earlier point. There are some purple and green colored horizontal lines displayed on my screen that seem to be static. These lines are also about the same length and are aligned in columns with space in between. See below for reference (image3). These graphical problems also can be seen in the bios (image1 & image2). Lastly, if I leave my PC idle for 10 minutes, the monitor goes to sleep (which is normal) and loses signal from the GPU. Unplugging the cable and plugging it back in does nothing, nor does plugging into a different monitor with a different cable. If this happens, the only way to solve this is to press the restart button on the front of my PC. However, I can avoid the monitor going to sleep by leaving a video or stream running. Description of Images for Reference: The first image is a picture of my monitor while logged into windows, with the graphical issue being seen in the windows UI on the left side - however the issue cannot be seen on the right side with a white background. The second image is a picture of the right side of my monitor while in the BIOS, some type of graphical issue can be seen in a localized area. The third image is a picture of the left side of my monitor while in the BIOS, the graphical issue isn't seen here. PC Specs: CPU - AMD FX-6300 Six-Core (3.50 GHz) Cooling - Cooler Master Hyper 212 Plus Motherboard - Asus M5A97 RAM - PNY Optima 2x4 GB & 2x2 GB Dual Channel DDR3 (1333 MHz) = 12 GB GPU - Radeon R7 265 Sapphire Primary Drive- OS & Other media: Western Digital Caviar Black 500GB Secondary Drive - Additional Games: Samsung 860 EVO 500GB PSU - Corsair CX750 Builder Series ATX 80 PLUS Bronze Display - BenQ XL2411 (144Hz) Operating System - Windows 7 Home Premium Service Pack 1 (64-bit) So, my question is: What is the problem? I can't seem to figure it out. Is it solely a GPU problem or a combination of other things? I don't have enough experience to figure this out on my own. I've tried everything I could think of and spent days browsing other forums for similar problems and what worked to fix them. P.S. I will update this to provide some additional information, but I figured I would post this to get some feedback.
