It never crashed under load, really it's quite random. It seems like it crashes when I'm using the internet. I still haven't tried a virus search in safe mode, so I'll do that soon.

 

What's UPS and CAPS? I don't know how to check my CPU's or video card's voltage, but since I got a new 750 Watt PSU, it should be more then enough.

Sorry for the bump, but I've just installed windows on a different HDD, and it seems it crashed when it was updating itself after you try to turn off your computer. When it says stuff like Installing updates 1/89. Apparently I had 89 updates to install (since I've just installed it), and the computer just hang at 40/89. Same crashing, numlock is frozen, reset button doesn't work, nothing.

 

I haven't ruled out another possible cause, which is:

 

Also I'll be turning to cable internet, instead of wireless, so we'll see if that'll fix it. Like I said I usually crashed when I kept uploading or DLing stuff.

Try booting into safe mode and doing a virus scan. I recommend malwarebytes for the scan. (Really don't think that is the issue) The problem sounds more like an issue with your ram more than anything. A check you can do is to boot into your computers BIOS setting and see how much ram the computer detects. If the BIOS  detects both ram sticks, try moving the ram into a different slot.

 

A UPS is a Universal Power Supply (think of it as a backup generator for a temporary power outage. It allows you to save files and shut your computer down in the case of a power outage versus losing everything when the power goes out. Caps are referring to capacitors. I believe he is referring to the video card capacitors. It would not be a bad idea to look over your motherboard for bad capacitors. (see rss371 post)

 

Power supplies degrade performance as time goes on. Probably a wise idea to keep the new 750 watt PSU. Electronics can be damaged by not getting enough juice to run. As for checking the voltage on PSU and GPU, I'd recommend using Msi Afterburner.

 

Windows updates issue: Windows could freeze, stop, or reboot during the startup process because of damage to a driver, important file(s), or damage to part of the registry. A System Restore will return all of those things to their last working order which could solve your problem entirely.

 

Have you tried to see if the updates would just continue, the updates will not allow you to do anything until they finish. It is not a good idea to try to turn off the computer when it is in the process of updating. This can lead to corrupting important files needed to operate the computer.

 

As for the hardline to the internet, keep using it and remove the wifi card to see if that resolves the issue. The card could be going bad and causing an electrical spike which would cause the crash to protect shorting components. 

Yeah I've already tried booting into safe mode and doing a virus scan, with exactly that software. It's definately not the RAM, since we changed that first, now I'm running on new ones. We also tried moving the rams to different slots, didn't work.

 

I do have a UPS, and that's our next guess that the problem lies somewhere on the motherboard, so if I still crash even after switching to cable internet, we're gonna have to replace that.

 

I know about windows updates, however what this one did was install 89 updates after I exited windows, and it had the same crash, I had before when I'm uploading to YT or whatever. Every time windows installs an update you can see the little cyan colored circle working, however when it reached 40/89, everything froze. Numlock didn't work, mouse didn't work, and I bet if there were any sounds, that'd have gotten frozen as well. I waited at least 10 mins for the computer to get back, but it just didn't.

 

Also thanks for your ideas.

I think your problem is a thing called TDR checker monitors the computers hardware, particularly the GPU, is say the GPU stops responding with the computer for 2 seconds TDR checker restarts the driver. The TDR checker was good on paper but did not work in the real world. as a graphic card can stop responding when it is working hard.

Issue since the time of vista.
 

Solution:

Exit all Windows based programs.
Click Start, type regedit in the Search box, and then double-click regedit.exe from the results above. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Browse to and then click the following registry subkey:
HKEY_LOCAL_MACHINESYSTEMControlSet002 (sometimes called ControlSet001) ControlGraphicsDrivers

On the Edit menu, click New, and then select the following registry value from the drop-down menu specific to your version of Windows (32 bit, or 64 bit):

For 32 bit Windows
Select DWORD (32-bit) value.
Type TdrDelay as the Name and click Enter.
Double-click TdrDelay and add 8 for the Value data and click OK.

For 64 bit Windows 

Select QWORD (64-bit) value.
Type TdrDelay as the Name and click Enter.
Double-click TdrDelay and add 8 for the Value data and clickOK.

Close the registry editor and then restart your computer for the changes to take affect.

This puts a delay on the tdr checker of 8 seconds thus the gpu can stop responding for 10 seconds, usually this fixes the problem, if you are still suffering from this issue (after updates or a reinstall of drivers, you know all that annoying driver stuff)
Then do this, do the same thing but instead of "TdrDelay" type "TdrLevel" enter the data value as 0 (it is set to that natively, but double check) then delete the TdrDelay, 

Restart 

That completely turns off Tdr checker, so now windows 7/vista/8 now works more like windows XP

 

Hope it works :)

Thanks, but now that we installed cable internet, I haven't had a crash since. We installed it like 5 days ago, so I'm pretty sure now, that was the problem. I haven't tried uploading to YT, but I did a lot of DLing, and like I mentioned at least once my computer crashed every day, but now I didn't have one.

So yeah, the problem was probably hardware failure. My guess is, the wifi card wasn't compatible with my motherboard.

Nice, Congrats Kanyo. Looks like that did the trick. Enjoy
