I've searched in Google, but I just want a second opinion before making a final decision and spending money on something that may not be needed.

My computer was old, so I decided it was time to upgrade the motherboard and CPU. I bought an Asus P5S800-VM motherboard, an Intel Celeron D 336 2.80GHz Socket 775 CPU, and also a 350W PSU. I have a Maxtor 10GB HDD, Quantum Fireball 20GB HDD, Lite-ON CD-RW and floppy drive came from my previous computer, and had no problems with them.

One thing I haven't mentioned yet, is the RAM. I'll get to that in a second.

Whilst installing Windows XP Professional, I had a BUGCODE_USB_DRIVER (0x000000FE) error come up, forcing me to reboot. It's only come up once, and during that time. If I'm correct, it has something to do with the CPU and HyperThreading. Also whilst installing, I got a PAGE_FAULT_IN_NONPAGED_AREA (0x00000050) error, which I again had to reboot.

Eventually it was installed, and I was in Windows. Not long after did my computer start spontaneously rebooting. At times there would be no notice whatsoever, it would just reboot. Sometimes I would get an error, PFN_LIST_CORRUPT (0x0000004E). I lost count as to how many times my computer rebooted and I got that error. Also worth mentioning, the second I get into Windows, I get an error box saying that an error has occured, do you want to send the report. Always comes up each time I get into Windows. I've also gotten IRQL_NOT_LESS_OR_EQUAL (0x0000000A) once or twice too.

Now about the RAM. The RAM is PC2100 DDR, but it's not new. I've had it for quite a while now, waiting for the day I bought myself a motherboard that supported DDR. I was given the RAM a while back, but I didn't know if it was working or not. They are 2 sticks of 256MB, equalling 512MB. First attempt to boot up the computer was unsuccessful; POST beeps telling me that something was wrong with my RAM. One of the sticks of RAM appeared to have been burnt previously, but not by me. Something I overlooked. Now I just have the 1 stick of 256MB RAM in, and the computer is working, but not how it should.

Google pretty much says that my problems are related to the RAM being corrupt and defective. The motherboard, CPU and PSU are new, the HDD, optical drive and floppy drive are not but I know they have no problems as I've used them before with no problems. The only thing I can put it down to is the RAM, as it's the only odd thing out.

Does anyone think there could be any other reason as to why my computer keeps randomly rebooting, displaying sendable errors non-stop and showing me the PFN_LIST_CORRUPT error?
