PC Crash

[Spitzer]

My PC has been crashing a lot lately. Used to be a minor issue a few months back. However, now it crashes a lot (like once every few minutes), requiring me to hard reboot it. Sometimes my PC crashes when I am watching YouTube videos or playing games, rendering my mouse and keyboard unresponsive, and my audio will stop. In rare occurrences, my PC may even have a BSOD Also, I noticed it usually crashes within the first half an hour after starting up my PC. If it does not crash during that period, it usually operates fine for hours after that.

I am uncertain where the fault lies, and have tried defragging, updating software of all my drivers, trying some hotfixes and performing registry cleaners. I may have missed out some software solutions but now, I am quite certain the problem lies with hardware. However, I am not really good with PCs, so I do not really know where the problem is. How should I proceed from here on?

My PC specs are as follow (custom built, 3 years+ old):
Intel i7 870
nVIDIA GeForce GTX 460
GIGABYTE P55A-UD3
Kingston 8GB DDR3 SDRAM
Microsoft Windows 7 Ultimate (x64) Build 7601

try going into safemode via f9 before windows loading screen.

see if you hang in safemode. If yes, means hardware wise having problem. Chances are the harddisk is failing.

If no, means maybe ur drivers are screwed. try uninstalling gfx drivers first

Things you can do:
1. download HWMonitor.exe to check your voltages/temperatures
2. download memtest86 to check memory

Btw, which brand/model is the power supply unit?

If there are important files, better to backup now. Seems you hard disk or PSU is failing.

Try the following if you suspect it's a hardware issue.
1. Reseat the RAM modules. If you have done it before, go youtube and find out. IF problem still persist, boot with 1 RAM module. IF problem still persist, boot with 2nd RAM module.

2. After doing all with RAM modules and problem still persist, reseat your GFX.

Remember to power off (off main switch) when doing reseating.
