Blue Screen, IRQL_NOT_LESS_OR_EQUAL

Hi,

I was attempting to reinstall my windows XP professional on my Dell Precision 690 workstation.  I had wiped my computer due to a nasty spyware/malware that infected my network [System Security V4.52].  Anyway, I had decided to reformat my computer and reinstall windows from scratch due to this error, I believed it time to start from scratch on my computer as it was.  Well, I got the partition reformatted, and set up for the NTFS setting.  Well when the operating system attempts to install it starts at 39 minutes to completion.  As it installs the drivers/devices into the hard drive, the moment it reaches 34 minutes remaining, a blue screen comes up displaying the following code:

IRQL_NOT_LESS_OR_EQUAL

This is followed by telling me to disable the caching and shadowing options for the BIOS Memory, first I have no idea where that is in the BIOS setup since there is nothing stating about disabling caches.  Following at the end of the blue screen it displays:

STOP: Ox0000000A (0xFFFFFFE0, 0X00000002, 0X00000000, 0X805373D2).  This is also followed by a physical memory dump each time.  I've attempted at reformatting the partition several times as well as running the diagnostics on the system memory.  Everything checks out fine.  Using the forums as an information guide, I've attempted various solutions and have had no results.

Any suggestions as to why this is happening when I only attempt to reinstall windows and how to fix this?
