please help, bsod 5-20 mins after booting up

[endforce]

Hello,

I put together a system about 6 months ago. Here are the specs:

Gigabyte n650sli motherboard
Intel E6750
MSI 8600GT 256MB
Corsair 2GB RAM
2x WD Caviar SE16 250GB hard drive
Lite-on dvd burner
Rosewill RP500-2 ATX12V v2.01 500W Power Supply
Rosewill R5604-TBK 0.8mm SECC Screw-less Dual 120mm Fans ATX Mid Tower Computer Case
Windows XP home

I didn't have any problems at first, except for some occasional lockups. For the last few months the problem has been getting worse. I would get a BSOD or lockup within 20 minutes of booting up. I did notice that if I restart my computer right after booting up, I would not get any errors. I tried updating all of my drivers, but that didn't help. Please help, any suggestions would be greatly appreciated.

Any number of reasons could be causing the problem. You might start by setting up your RAM correctly in BIOS. Bump up the RAM voltage a notch or two. PC6400 is 2.0-2.1v. Set the timings manually to 5-5-5-15. Run memtest. If your RAM specs call for 4-4-4-12 try the system there after you have tested with adequate voltage and a run of memtest.

Memtest is included on Ultimate Boot CD here.

Check for bulged / leaking capacitors on the motherboard... wouldn't hurt to check your power supply either.
