XP pro Installation woes

[yanquii]

Firstly, here are my system specs:

AMD Athlon XP X2 4200+
Asus Nforce 4 A8n32 SLI Deluxe
2 gig Mushkin DDR 400
Western digital 250 gig hard drive
Evga 7900 gt ko

Now, I am in the process of reformatting my computer for the second night in a row. I reformatted and installed xp successfully last night, and now I am having some serious issues.

I installed the latest bios for my board and all that jazz last night, and everything seemed to be working perfectly fine. I turned off my computer before I went to work this morning, and when I got home today and fired my comp up, I got a BSOD saying that my computer was not fully acpi compliant. I went into the bios and found the setting to disable or enable acpi. I tried both with the same result. Below is a screenshot of the error.

After reading up on the internet, I found, on microsofts website, that when asking if i need to install a 3rd party raid driver, i should hit f7 instead of f6 to bypass the acpi check. I did just that, and then ran setup again, only to get another error labeled BAD_POOL_HEADER. Heres a screen:

So now, I am at a complete loss. I am thinking that my BIOS may be screwed up, but I dont understand why it would work ok for a day and then decide to crap out.

Any help would be much appreciated.

Thanks,

Andrew

hmm I seem to remember getting that when I had my cpu settings wrong, try using the lowest settings possible, to test

Well, I found the problem. I turned my external hard drive off that night, and that was when the problems started. So, I turned it on and everything has been working perfectly fine. I installed XP again with the External drive on and it was perfect.

Why would this matter at all?
