Hi all, I built a pc a while ago and it's been working fantastically, until I had a busy period at work, and didnt use it for a few months Cpu i7 5960x Ram 8x4gb ddr4 Gpu titan xp Motherboard asus x99s I think there may have been a power surge at some point due to crazy weather, but other than that nothing out of the ordinary Anyway, the PC starts, shows a signal, but gets stuck on the attached screen prompting me to go to bios to restore settings, bur when I press the button to go to bios, it goes to a black screen (not no signal) I have tried Clearing cmos with motherboard button Removing cmos battery for 5 mins and replacing Replacing the battery with 2 others Discharging the psu Changing the psu Reseating the cpu Removing cable extentions from the PC Changing power cable Rolling back bios and updating bios through asus flashback I don't have another motherboard or cpu to test with, but wondered if anyone had some advice before i go buy a new motherboard and cpu. I'm out of ideas I hope its ab easy fix. I love this system so much, and would rather not have to upgrade just yet. Thanks in advance

So I have an ASUS H170 Pro Gaming board with I5-6600K. As you know I can't OC on this board but I saw an CPU_OV jumper on the board and I was wondering what is it for? I mean it is for overclocking but I can't overclock or can I? If I can't then what is it for? I don't get it.

Hi,I need help figuring out what’s wrong with my computer. I built this machine like two weeks ago(my first one) Amd ryzen 7 2700 gtx 1660 ti 16gb ram I tried overclocking my gpu which went just fine. I also tried overclocking my cpu and i think i overvolted or did something wrong. I tried to go up to 3.8ghz(base 3.2ghz and max 4.1ghz) i set the voltage to around 1.2625.My pc shut down and restarted,when i went back to ryzen master it said that the overclock was unstable anf my settings were back to default.Now i keep getting BSoD eveytime i try to run games like warzone or rainbow six,sometimes even when watching youtube vids or doing school work. I reset my computer,installed a clean version of windows,reinstalled my drivers,troubleshooted,even changed my C drive but still nothing worked. I ran stress tests and everything went great,but when i stress tested the cpu it gave me BSoD What do i do? Did i burn my cpu? Help

I just noticed a week or so ago my CPU voltage was fluctuating and getting way too high, like 1.46-1.7 volts. I tried manually overriding the voltage in the bios to lock it to 1.35, this made it go up to 1.6v even though the setting was saved as 1.35. If I leave it at default auto setting it will boot, but the voltage will dangerously fluctuate. I tried using different bios revisions all with the same outcome, so that leads me to believe it is a hardware issue. I'm having trouble figuring out what component is causing the issue. I have a spare PSU I was thinking of swapping in to see if that fixes it. Anyone have any idea what it could be though? My hardware is as follows; Mobo: Asus ROG Maximus VIII Hero Alpha CPU: Intel 6700k with a 280mm AIO cooler PSU: Corsair HX850i Graphics: GeForce GTX 980ti with a 280mm AIO cooler RAM: G.Skill Ripjaws V 2x8gb ddr4 3200mhz And 2 HDDs and 3 SSDs

I have the following rig MSI Z370A Pro Intel i7 8700K Corsair H45 Cooler Corsair ven 8GB×2 Corsair TX750M PSU Gold Seagate 1TB 72000RPM About to buy GTX 1070Ti Now a few days before, I encountered a power voltage fluctuation to 200-400V in my house. My refregirator stabilizer showed me the output and I was lucky I didn't turn on my PC and the switch was off. So can you please recommend a decent stabilizer for my pc( I would like if it had an electronic display of input and output current and voltage values) and I live in India and I hope I get such a voltage stabilizer in my place

I have this psu Corsair TX750M and it's a 750W power supply and what happens if I get power input of 400V? I recenly have high voltage issues in my house and will it damage the psu or is there any chance it could damage the whole motherboard? Or can I trust the psu so that it will prevent the damage? Please contact everyone in this topic and tell me

I wanted to undervolt my CPU to 1.180V but I forgot using the dot (.) and the motherboard set it to 1700mV and I didn't see it before pressing F10. When I rebooted, a message warning the high voltages and temperatures appeared. When I entered the setup, the CPU was @ 87ºC and 1700mV. Immediately pulled the plug, waited 30 seconds and cleared the CMOS. Everything went back to stock. More than 2 hours using the PC, no BSOD, no Freezing, no nothing. Am I ok? 945 points @ cinebench.

Hey guys, so I've been having the issue where my motherboard seems to be over volting my cpu. I've done a bios reset and even updated to the most recent, but for what ever reason the cpu voltage is 1.42 volts. I've even went in and set the voltage to not go over 1.3volts. I dont have an overclock on it so it's the base 6700k clock. And I'm pretty sure this is also why I'm having temp problems. Sometimes the temperature will just skyrocket and on heavy load I've observed 85-90c. So I haven't really been using it. If anyone can help me figure this out it would be greatly appreciated. Thanks

I recently killed three hard drives with a new (to me) power supply. The new one is this older Antec 850w, 80+ bronze. I'm no longer that heart broken over losing a bunch of data, so I've at least been trying to figure out what I did wrong or what was wrong with the power supply. I can't find many other people in the same position on the Internet, and all the responses are varied. I plugged the hard drives and an SSD in after testing the power supply elsewhere first to make sure it functioned properly and wouldn't straight kill everything; I figured I could trust it in my computer. However, within a few hours, I was sure the hard drives were totally dead every since that initial instance. The SSD still operates as normal though. I've built a few computers through the years, so I don't think I was doing anything fundamentally wrong. I've also never heard anyone warn about something like this. I thought SATA was a standard so this wouldn't be a concern. I guess they received the totally wrong voltages? Were the voltages switched somehow, 5v and 12v in opposite places? Could a bad power supply do this and simply not affect the rest of the system? If you have any opinion, dropping a note would be great. Thanks

So here's the deal - my motherboard is pulling over 13.5 volts from the psu. I have tried 2 other psu's, a cheap chinese one and a corsair cx750 and both of them reached about 13.8 before overvoltage protection kicked in. Specs: GA-H55M-USB3 mobo i3-540 cpu 2x2GB Kingston DDR3 ram GeForce GT440 gpu 2xSATA drives (Samsung and Seagate) I have swapped all the components into another case but same story. Changed CPU coolers, no effect. Also the CMOS battery was replaced 3 months ago and its on 2.8 volts. With the system powered off the 12v rail shows an inconsistent voltage of around 0.5v. Im out of ideas and time plz help!

So it seems that when people ask "how many volts is ok to run in my XXXX cpu?" They are given a random figure based on other random figures based on guess work and assumptions.... Can anyone show me (or have experience with) long term CPU usage on high voltage (say 0.5v above intel recommended spec for that cpu) where cpu degradation has caused either: A ) higher running temps B ) more voltage required to reach stability months/years later C ) CPU death A great example would be a hugely overclocked FAH or BOINC rig that has seen many many hours at 100% load (with small cycles between jobs)

Hey guys, quick but important question: I own an Asus R9 280x DCUII TOP that has minimal artifacting and I KNOW by research that its because of VRM overvoltage in the video card bios. The default should be 1.5V wich even afterburner sees as default but in the monitor it shows 1.6V wich is what is causing the artifacting. I cannot set it lower for some reason, what should I do? The artifacting is REALLY minimal, I can live with it perfectly but sometimes I prefer to be safe and find solutions for what can get worse over time. Here's a screenshot of MSI afterburner:

I have been doing an out-of-the-case build without a case (Because it's a server...) The motherboard, Gigabyte F2A78M-D3H mATX FM2+ motherboard. The processor, AMD Athlon 860K at 3.7 GHz The GPU, NVIDIA GT 720. The recent powerups have been successful, and I have installed Ubuntu Server on the connected storage device, successfully. (Just to claim it boots) But then, my screwdriver power-pin trick seemed to stop working (it actually never does), so I put the floppy connector from the PSU (450W) to the power jumpers. It burned out a chip right beside it. Results: My system boots right after I turn on the power supply. Fan runs, but no video output, no POST. Is it going to be bricked CPU, GPU, Chipset, etc.; Or am I going to solve the problem by RMA'ing the board?

So basically my pc is shutting down while gaming. Before you guy ask for the temperatures [cpu max ~60, gpu max ~60]. So i figured it could be the power supply! But i am not sure, any ways to check and ANY SOLUTIONS please? Thanks!

Sometimes when I make build list in pcpartpicker it says my ram voltage is ofer the haswell refresh limit basically it says the limit is 1.5v but if the ram say runs at 1.65v should I be worried Pls help MRE

Hello everyone, I had a little "accident" yesterday, first I'll put up all my hardware: (CPU) AMD Phenom II X4 965 Black Edition (Mainboard) MSI 880GM-E41 (GPU) Gigabyte Radeon HD 6850 (PSU) One of these very old (china made) ~400 Watt max (I was about to buy a new one... really...) (CPU Cooler) Scythe SCMG-2100 Mugen II (If you need more information, just tell me) So far so good. So yesterday I found an old CPU fan from my AMD Phenom which I thought was a good idea to use as another little fan to make air flow a little better in my PC and yes I was quite bored but I thought it was still an idea. So I plugged it into my motherboard, started everything up and wanted to find out what would be the best positioning for this little fan. I started up Prime 95 along with SpeedFan to messure everything but I realized that my fan was still plugged in which would have falsified my results. Quickly I pulled out my phone, looked up "Can you unplug fan while" and found this little post: http://www.overclockers.com/forums/showthread.php?t=591070 Convinced that it works I just unplugged it while it was all running (probably my worst idea ever). After bout 5 to 10 seconds my PC shut down and the LEDs at the front (I only have like a large one, probably for status(?)) was left blinking. Shocked of it I unplugged my power supply and was waiting for a little while. After that I plugged in my PSU again and was hoping that my PC would turn on... but it didn't. I tried everything, unplugging my graphics card, my RAM, my CPU but nothing worked at all. I'm about to send it back on warranty and will probably get it back repaired (also going to get a new 750 watt PSU along with it ;) ) but I am still curious about what happened when it shut down. I was discussing with a friend for quite a while and he first thought it was my poor Mainboard or my CPU but we were not 100% concerned about these thoughts, so that is why I am coming here to ask people for their opinion. I also tried putting another PSU to my PC but nothing happened. Then I checked if my HDD or GPU had any issues but luckily they hadn't. Unfortunately I can not check my CPU because none of the mainboards that I have access to have an AM3 socket so all there is left that could be damaged is either the mainboard (very sure because otherwise the PC would at least turn on) or my CPU (gonna send both in for repair btw). One thing I tried this morning was hooking up the old PSU to my mainboard again and trying to start it up. The fan inside was slowly spinning with almost no noise (it is usually quite loud) and I unplugged it again... I guess it's broken but please tell me what you think (I do not have a voltage meter around me, sorry). I just wanted to get a little discussion about this going because I just started a computer science schooling/education myself and I like to understand hardware much better and this is why I started this topic. Hope there are some good explanations out there... (I am German btw so excuse any mistakes ;P)

Hi, I know that the overvoltage of graphics cards puts more heat and reduce the life time of the card but I couldn't find clear answers to my questions on the interweb so I'm asking you guys: When do I have to overvolt my GPU during an overclocking? (When do I know I have to crank the overvoltage to continue overclocking?) How do you use the overvoltage, directly maxed out or do you have to increment? Thank you.

Does voltage matter if you can keep the processor cool enough? I personally have a 3570k and have gone quite a bit above the recommended max voltage but I am using a All in one 240mm cooling unit and in my Aida 64 stress test my max temperature is 78 degrees. it is at 4.5GHZ and the voltage is 1.425. JJ from asus said the max he recommended for ivy bridge is 1.325 but his particular chip and cooler was at a much higher temperature than mine even though my voltage is higher
