Hi there, I wonder if anyone can help out with my series of strange PC related problems. I've been building PC's for a few years now and have run into a series of rather strange problems on my latest PC. Specs are :

XP3000+ Barton with Coolermaster Cooler (not clocked)
1gig (2x512mb PC2700 Corsair XMS memory) running at CAS 2 (7332)
Connect3D Radeon 9800Pro 128mb
120gig Maxtor ATA133 8meg Cache
Asus A7N8X Mobo (inc latest 1004 Bios)
SB Audigy 2
Antec Lanboy Case (350)PSU

I have Windows XP Pro installed with all updates (inc SP1a).
I have a few problems with this new system :

1. CD RW Drive occasionally disappears from system (jumpers are correct, its one of two IDE drives connected on Secondary.. other CD is basic 52x Samsung). Message in event log is akin to 'device has unexpectedly been removed from system'. Managed to get the drive back up again once i fiddled with cables but not 100% sure that this is the problem.

2. Exclamation mark on CPU in device manager - this has only appeared yeserday when i installed the new nforce2 mobo drivers from nvidia's web-site. Also, upon running windows update, there is a 'cpu processor' upgrade driver which wont install even those it is listed as an update. failure message is something like 'device locked'. i suspect this is due to my using the CPU when i'm trying to update the driver!!

3. Occasional crashes to POST screen - without warning and no error message i will get a crash to POST. Resulting windows error report upon reboot mentions a STOP at 0000000x or something?? This always happens in games but it can run for hours before it does it.

Oh, and another small snippet of information... upon one of my many crashes, one of the error reports in windows upon reboot actually told me that the CPU had detected a hardware/device failure.

The best bet i can think of is that the memory/CPU is faulty. CPU at load runs about 50c and idles around 44C. Mobo is idle about 22c

Anyone got any ideas?? This is doing my head in!!! Any help would be greatly appreciated!

Thanks, David.
