Help diagnosing strange problem

[chisaipete]

Okay, first off, no flaming for the dinosaur of a box I'm running. An upgrade is cooking itself up, but I'm a poor student barely making rent.

Specs:
Thermaltake TR2 W0070RUC 430W ATX12V Power Supply
Athlon XP-M 2400+ Barton 35w CPU (OC'd to 2.3Ghz 200x11.5)
Mobo DFI LanParty NForce2 Ultra B
1 GB (2 x 512MB) Corsair XMS DDR 400 PC3200 RAM
HDD(s) 2 80GB Maxtor DiamondMax 9 SATA in RAID 0 and 2 120GB Maxtor SATA in RAID 0
Wintek Geforce 6800 128MB AGP Video Card
HDMI to Sharp Aquos 32" LCDTV @ 1080p

Problem:

Boot up fine. Windows loads fine. Then, magic freeze.

Type of freeze...all comes to a halt. Still have great image, just stillframed. Occasionally the mouse movement over buttons will register (highlighting buttons and such) but then in a few moments, it will totally freeze.

Mysterious freeze-up 25 sec to 2 min after boot when clocked to 2.3 Ghz (200x11.5).
Freeze-up a little later...like 30 min after boot while running 3ds Max while clocked to 2Ghz (200x10).
Appears to be fine @ 800MHz (auto detected BIOS default.)

Now, obviously it looks like my processor...are there work arounds? Is it really my RAM or my Mobo? Video card?

Obviously I tried some minute testing with the CPU, but I don't feel it's conclusive.

I ran Memtest86+ on my OC'd ram...I forget the timings but they are tighter than detected and had no errors.

Please, suggestions would be very helpful. Any other tests I should try?

My goal is not to resurrect the dino, but simply to keep it alive and functional until I can afford an upgrade.

Follow some of the steps listed in the basic troubleshooting sticky, but run everything at their stock/default speeds. Let us know what the results are after each "step" you take.

try removing as much as you can before botting up, then replace one at a time, to see if a perhpial is causing it.
