New computer problems (possibly CPU)

Hey all, just ran into some trouble. I'm done setting up the new comp, and decided to test it with Prime95 since I had upped the memory voltage to 2.8V to get it to run stable at 2-2-2-6 timings (Mushkin Level II PC3500). Ran Prime95, and left it on overnight.

I just woke up, turned on the monitor, and Prime95 failed almost 6 hours into the testing, saying I had a hardware problem. I thought maybe I gave too much voltage to the RAM, though I know this RAM can take the extra .15 volts extra I gave it. I restart Prime95, and it flakes out on the first test with a rounding error, which leads me to believe the error was the CPU. I right click My Computer, click Properties, and it doesn't show my processor.

I restart the comp, and on POST, and the screen doesn't report my CPU specs like it normally does. The CPU is recognized in BIOS, and when I restart the computer, it randomly POSTS with the CPU, sometimes not, but after it finishes loading windows, it promptly reboots.

What's wrong? Is the CPU flaky? I'm pretty sure it's not the RAM, it runs fine after multiple cycles of memtest86, and I know they can handle 2.8V.

The system is still stock clocked:
P4 2.4C / Abit IC7-G
1 GB Mushkin Level II
Western Digital 160 GB
Lite-ON 52x burner
Audigy 2
Radeon 9600XT

It's a brand new system (parts all bought 3 weeks ago, comp is only less than a week old), so I can still RMA the proc or anything if needed, if that's the case.

Thanks for any help.
 
Are you overclocking? If so, you didn't tell us what speed you were running at, if not stock.
 
Everything in the system is stock clocked.
Only thing I've done is boost the memory voltage to 2.8 V from the 2.65.

So yeah: I booted up memtest86, all it does is count nothing but errors. This system passed every pass yesterday at higher mem voltage and tighter timings (2-2-2-6 @ 2.8V), but I relaxed the timings and voltage and it just gives errors (2-3-2-6 @ 2.7V), so I'm really thinking the CPU's a goner.
 
Up up and away.

If anyone else has suggestions on what might be problem (either CPU or RAM at this point, everything else in the system works (vid card displays and such, drives work).
