ABIT AN52V bios issues

[beachy532]

Computer I am trying to fix is running a
AMD Athlon 64 x2 6400 cpu
4 gb Corsair xms2 (2 sticks of 2gb)
500 watt power supply
Abit AN52V with a phoenix bios

I have been informed the computer is at least one year old and was working fine. Then it started throwing up BSOD and would only boot into safe mode. I entered safe mode backed up all required data and attempted to repair the installation of windows XP (sp3) it failed. While doing a fresh installed it failed during the GUI portion of the installation throwing up a BSOD with the IRQL_NOT_LESS_OR_EQUAL. I attempted to reinstall using different discs and drive still throwing up the BSOD on the gui part showing IRQL_NOT_LESS_OR_EQUAL.

At this point I believe it was a RAM issue and began to use one stick in a different slot every time. It would throw up different errors every time but looking into the error codes it always pointed to ram. It seemed both RAM sticks went bad at the same time. Deciding to use memtest x86 I popped the CD in and restart.

The bios hung, it displayed I had 2tb of ram at 128 bit. Great now what? So I guess is i the RAM, the mobo, the power supply or something else I am not sure. I should also add it hangs on detecting IDE drives, there is only one IDE slot yet hangs after seeing no IDE in the first channel.

EDIT I fixed the bios hang, reset cmos and one sata cord was loose put it in working much better! =) windows still no go, prolly ram issue

You need to flash the memory for the Bios as it may be required. Flash the bios for the system with the latest file that is been required. This might then help you out to work.
