1) Heat related issue
2) Failing RAM stick
3) Inadequate power, especially where new power demand was added.
4) video driver related
5) other driver related
6) malware of some sort
I believe that's pretty much in order of most common to least.
I've started having problems with my computer these past 4 month, it has started to randomly freeze, although I use the word "randomly" quite lightly. This is due to the fact that the computer has only frozen during longer periods of playing computer games. Another thing to note is that during these past 4 month the computer has only frozen a total of 4 times.
So far these freezes are mostly an annoyance, but in case they are to get worse I'd like to know what's causing them.
Seeing as I've tried to troubleshoot as best as I can, I've come up with nothing to point to the cause, but I'll write down what I've done so far. But before that I'll mention the 2 big factors which happened just before these freezes began, if they are relevant or not, I do not know.
Just before these freezes began I bought an SSD and reinstalled Windows 7 on it. So with my current setup I use the SSD for the OS and software, while games, music and movies etc are stored on the HDD.
As I said, I do not know if the SSD is at fault or not, I'm just saying that the computer began freezing after I got the SSD, relevant or not.
I'd also like to clarify the problem. At certain points during longer periods of gameplay the computer slows down to a halt during 1-2 sec, the picture on the screen freezes, the sound begins a 1 sec loop, mouse and keyboard become unresponsive. I did at one point wait to see if something happened but after 30min there was no change and I had to do a hard reset.
So after this happened the first time I did what I always do if there is a problem such as a bluescreen etc, and that is to check the Event Viewer and look at the logs. But so far there has been nothing logged about what could've caused the freeze, there is no mention anywhere what could've happened.
Seeing as I gained no information from the event viewer I began to check the hardware. I began with running the Windows Memory Diagonstics Tool during one night and it came up with nothing. Then I went on to check my SSD and HDD using the chkdsk.exe and that as well came up with nothing.
After this I began to monitor the temperature of the GPU and CPU. The GPU is at a steady 80° during load, and the CPU is at a 60° - 70° during load.
I've scanned for virus and malware and come out clean. And all drivers and updates are up-to-date.
If anyone has any idea what could be the cause I'd really appreciate it.
