I don't know about the outlets and am not interested in trying to re-create the freeze. The house was built in the 50s and renovated in the late 90s, but I'm not sure exactly what renovations were made. These errors also occur when I initiate a regular safe shutdown or when Windows update runs, according to the event history. It's possible that as I was force shutting down when the freeze happened, Windows was still able to report some things and that the drive errors were just associated with the shutdown and not the freeze. That type of freeze (where the audio locks into a repeating note and Windows is completely frozen) is something I've seen with faulty memory and unstable CPU overclocks. I am currently overclocking the CPU, but it is "stable" (as in stable in everything besides prolonged Prime95). Memory was checked with memtest86 only a few weeks ago and is fine. One unlikely possibility is the RAM though. I know that my RAM can error a bit if I set my tREFI value to max combined with high room humidity. tREFI is known for making RAM unstable when ambient temperatures are warm or humid. My room was humid because I was sweating from all the work I was doing, but the thing is that I already had my tREFI value set to a more safe value even though it's still in the "tuned" tier and not completely stock tREFI. Even still it's possible when I pushed the computer some kind of change in air pressure or temperature caused an error on the RAM. Thankfully the computer has been running fine for an hour since I restarted with no new errors in event viewer.

Hard wood flooring. It's an mATX case. The SSD is mounted vertically on a corsair metal mounting bracket which is mounted to the front face of the computer sort of where case fans would go on modern gaming cases. Power supply is EVGA SuperNova 550 G2, with an i7-5775c and DDR3 RAM.

It's a Samsung 850 EVO SSD, but I have new info from event viewer right before the freeze happened. Three total errors occurring at the same exact time: Error: The driver detected a controller error on \Device\Harddisk4\DR4. Error: The driver detected a controller error on \Device\Harddisk3\DR3. Error: The driver detected a controller error on \Device\Harddisk2\DR2. I did an sfc /scannow and no issues were detected. Must have been some momentary short in the SSD's controller, maybe from static buildup or the vibration, but it seems fine now. Also interesting is that I saw a few of the same errors in event viewer 30-45 minutes beforehand, implying that the first time I moved the computer there were errors that also occured but didn't cause a system lockup. I geuss it could be the placement of my SSD in the chassis as it's mounted vertically to a bracket inside instead of horizontally in the drive bay. Or maybe SSDs just don't like that kind of vibration? Not sure but good to know not to move it while it's on. In fact, in my event history most of any error messages I can find are usually disk controller warnings. They do usually occur right before a regular computer shutdown or a windows update. But the vibration could still be related, not sure.

I was doing cleaning behind my desk and had my computer (on floor) and desk scooched up a bit, with music playing from the computer to my speakers. After I finished cleaning, I pushed the computer back to where it usually is and while I was pushing it the music and Windows completely froze. I did a hard restart and everything is back to normal, but I do want to know exactly what caused this to happen. Maybe a temporary short somewhere due to the vibration?

I upgraded my laptop display and it works fine 99% of the time, but there's a problem where if the picture on display is too high a percentage of one shade of red or blue, or isn't "diverse" in color enough, it will flicker and black screen. So I can watch a pixel test video in regular screen but in full screen, the red and blue slides will just black screen my display. It seems the threshold is about 2/3 of the display. The more homogeneous the colors are on screen the more likely I will get flickering, so I even see occasional flickering in YouTube videos but very very rarely. Stock screen was 1366x768, new is 1080p but the eDP cable pinouts are the same and the cable wiring appeared to be 2-lane capable, voltages pretty much the same in datasheets but I need to go back and check.Any idea what is going on? Edit: my current solution here, but still don't understand fully what is going on

A display I'm looking at to upgrade a laptop to, model NV156FHM-N4B, has "H-sync" (H-Sync for active pen) at pin 24 according to the datasheet. I assume this is for G-Sync support but I'm not sure, but it would be nice to know what it is and if it's necessary. I'm choosing between display upgrades for a laptop and really want this specific one for its high contrast ratio and color gamut, but the one problem is that my stock display doesn't use pin 24 on the 30-pin EDP connector, and after examining the stock eDP cable there is indeed no wiring for that pin. Maybe my laptop's firmware supports H-sync on that pin but probably not. It's an HP-15bs234wm. So, if all other necessary data/power/ground pins are compatible, am I safe to at least try this display out and expect it to work?

I could maybe turn the main case fan around so it blows inward. What do you think about that? I'll also try out the tRFC values, but I'd need to wait for it to be humid enough again because I've already aired out my room enough that it probably won't give me worse case scenario tests at the moment.

It may seem obvious that a 2-lane EDP cable is backwards compatible with WXGA screens designed for 1-lane cables, but I want to make sure this is the case. I intend on testing a 2-lane cable coming in the mail with my existing 768p screen. I thought, well if the cable at least works with my existing screen then I can feel safer to order the new 1080p screen, but now I'm doubting even that. The stock cable in the laptop is a standard 30 to 30-pin, 1-lane EDP cable. I assume that because different cables exist in the first place that the pin-out on the cable is different, unless it's just a cable quality thing like with standard vs high speed HDMI cables?

It would be cool to get some advice on my situation. I had an OC on my CPU and memory that initially tested fine and was running well for over a year. But recently, after I encountered a Chrome bug that made me suspicious, I wanted to double check, and after some trial and error with memtes86 v8.2 I found that my tREFI value was the culprit for new memory errors that show up within the first few minutes of the hammer test (#13). I'm already so close to stable that I only get errors in the memtest86 hammer test (#13), but not the others. I'm even able to pass older versions of memtest86 that don't have that specific test, so I'm thankful I was able to figure that out a while ago. I used to have tREFI at max (65,535) for over a year but now suddenly I can only pass a clean hammer test if I set to 15,000 or lower. That seems like a giant leap, no? I suddenly have to power refresh four times as often for the same level of stability as before? The one culprit I am currently thinking is that it could be the humidity in my room when I hang up clothes that didn't dry completely in the dryer. My dryer is really old and I'd rather not waste power re-running cycles for hours, so I have to hang some of the heavier pieces in my room. I've read that higher levels of ambient temperature may require lower tREFI for stability. I also consider the possibility that every time it's too hot or humid in my room I'm unknowingly running an unstable system but because it's a rare corruption, I don't blue screen but might have occasional file corruption or other bugs in Windows, like the one I just posted a thread about with Chrome causing what seemed to be a major CPU hang. Obviously I don't test memtes86 every week so I wouldn't know this is going on.

It was strange that it would cause the browser to hang because I can do things like gaming at high CPU usages and chrome still works fine. I didn't see any windows updates ran. But yeah I've known Windows to be really bad with CPU usage for certain tasks that shouldn't warrant it. I'm actually afraid to run a full system Security scan because it's one of the rare things, among P95 and other stress tests, that will lock or BSOD this otherwise stable overclock. Not sure if the security scan CPU usage thing is a bug on my system or intended but it's really scary. I'm also thinking chrome bugged the system and the system was trying to handle it and the hang led to high CPU usage. I'll run memtest86 to make sure.

Can PDFs infect your system? I've been browsing laptop screen models and checked some part sheets. Otherwise my browsing is always quite kosher. I also had a good amount of tabs open but I do that all the time and this system handles everything like a champ. I'm sure I could run 100 tabs and as long as there isn't a memory leak or bug/hang it will feel as fast as it does with nothing open. Extensions have been the same for a while but I do run an adblocker. That 50%+ CPU usage on my i7-5775c (@4.2GHz) was happening for like 2-3 minutes and during the time tab switching was taking seconds and as I was editing one of my posts I was getting hard lag on character typing. Like I mentioned earlier, text editor lag is something I've seen unfortunately too often online, but it's still relatively rare. In Windows task manager I'd see brief moments of "System" running at high CPU usage but for most of the time it was happening I couldn't see the source of the usage, like the process was hidden but was still adding to the total. Chrome usage was higher than it should have been but it wasn't adding up. I mean, usage up to 50-60% on CPUs like this is not normal for non gaming/pro applications. Chrome didn't show a particular tab eating up resources but chromes task manager isn't reliable for troubleshooting tabs in my experience. ATM I think it was just a rare browser hang considering that it stopped. Unless..LTT does mining in chunks and then stops so users don't expect anything.

It's like when someone says "dude you're so hyped right now how many energy drinks did you have?" That question doesn't mean they believe the only reason their buddy is hyped is from energy drinks, it's just to spark the convo. It could have nothing to do with energy drinks and it's still ok to ask the question. I'm leaning more towards some sort of anomaly that won't repeat. I never see that kind of activity and I don't visit this forum often. I've used other forums where the text editor can cause hangs but not sure exactly what happened here.

"a slow website does not instantly mean it's bitcoin mining your system"" Yeah that's why i asked the question to see if anyone else ever had similar experiences. Doesn't mean I was dead set on any conclusion, it's just what I made the topic title. I could've made it anything. And i asked why is it so slow for the sake of the conversation to get answers not because I was defending it necessarily being mining. You're extremely annoying.

Then why is it so slow? The letters are lagging as I type them in. My browser hangs with it open.

I never EVER have CPU usage issues with websites. Even really bad ones. But using this forum, I'm getting up to 50% usage on a high end i7, and a loud fan! I never hear my fan just browsing the web.
