Computer freezes ramdomly.
Hi guys. I'm new to this forum and I'm having a really annoying problem with my computer. I built the computer about 6 months ago and ever since I built it, it have just been freezing ramdomly like every 2-4 hours of use (sometimes even less.) For example, when I watch videos on youtube or play flash games it seems to freeze faster like within 20 minutes.
Oh and when it freezes nothing moves, the mouse/keyboard freezes and I have no choice, but to restart the computer. When I restart it evrything is back to normal, until it freezes again.
I know it is a hardware problem because I have used different OS and the problem persists. Plus, I've done a full virus scan many times, and I'm free of virus.
Here is some computer info:
NEC 16X DVD±R DVD Burner.
Seagate Barracuda 7200.9 ST3160812AS 160GB 7200 RPM SATA 3.0Gb/s Hard Drive.
Kingston ValueRAM 512MB 184-Pin DDR SDRAM DDR 400
AMD Athlon 64 3200+ Venice 2.0GHz Socket 939 Processor
Antec TRUEPOWERII TPII-550 ATX12V 550W Power Supply
DFI LANPARTY UT nF4 Ultra-D Socket 939 NVIDIA nForce4 Ultra ATX AMD Motherboard
Geforce 6800 gt graphics card 256 mb pci-express
in-board sound card.
Now, I'm using a large fan, so I don't think it is the heat. I'm only using 512mb of memory, so do you guys think that that could be the problem? I really need your help because I can't a solution to this problem.
Let me know what you guys think. Thanks.
