Computer Erratically Freezing!! Whats causing it?

[Sob Rogue]

History Up to Freezes:
Around the beginning of last month, the computer started to boot to a blank screen. I was able to get around this by rebooting to the "Last Known Configuration" every other time and succeed in the boot. Then around the middle of the month the computer froze. Following this freeze it randomly froze at no particular place or time. But, the time between the freezes started to shrink. (ie. Computer froze after 30min, next boot froze after 25min, and so on). This continued until it just froze when I logged in. I figured this might be a software issue, maybe the OS was dying. I reinstalled XP and it was fine for a while, then freezes started all over again.

I checked the HDD,good...checked Memory, good...checked mobo..good....Reinstalled drivers....not overheating...I'm out of ideas-What could be causing this? I should mention, I have never had any issue with this computer until now. Only thing that I have noticed, is if I only use one memory module, the computer will freeze less often, but both passed memtest 86????

Specs:
Windows XP Pro.
Asus P5ND2-SLI Deluxe
WD 250AAKS
1gb*2 PQI

Thanks,
Rogue

Try a different power supply.

- What PSU do you have?
- What CPU do you have?
- Have you tried upping the voltage on the NB/MCH?

Oh and I have that mobo. PITA sometimes. No freezes like yours but sometimes doesn't like to boot properly.

Just because Memtest passed does not mean the memory on memory controller aren't bad.
You said you tried it with one memory stick, and it froze less often. Try it with just the other stick in and see if it still freezes. If it doesn't then you know which memory module is bad. If it continues to freeze, then I'd say it's the motherboard.

Are you overclocking at all or have you in the past on this setup?

Got another power supply (wasn't as good), but nonetheless the symptoms remained...

I'm using a Enermax FMAII and an intel P4.
I did try to up the voltage, but only a small amount, for what ever reason this board has always run high for me.

I think you might be right about one of the memory modules being bad. I switched it out with the other and have yet to have to problem. I'm crossing my fingers and letting it run all night before I call it a success. Only half the memory though ..guess I'll have to be patient...
