I'm working on a Dell Vostro 220s with Windows XP. It has 2GB of DDR2 PC6400 RAM.
The owner contacted me because he was unable to keep windows running. Shortly after booting to the desktop, it would go to a 0xd1 BSOD. The BSOD refers to the ebthgy.sys file and the 'problem' was DRIVER_IRQL_NOT_LESS_OR_EQUAL. Prior to the BSOD, separate errors would appear stating that dsca.exe and aposumidinigo.dll were unable to run.
I attempted to boot to safe mode. Windows scrolled through the drivers it was loading for half the screen and stopped. After about 20 minutes a generic BSOD showed up.
I then attempted to boot to an XP CD to access repair. It loaded all the drivers; then when it was "Starting Windows" the screen went blank followed by a BSOD with a 0x7b error with no specific references.
Then, I received a blank screen when I tried to boot to VGA mode, boot to last known good configuration, boot to the Dell diagnostics and boot to the Dell utility partition. Since I tried the last known good configuration, I also get a blank screen when I attempt to boot to Windows 'normally'. In other words, I can't recreate the 0xd1 error.
All of the above was performed with the onboard video and repeated with a brand new PCIe video card in that slot on the MB.
The RAM has been tested extensively - A total of about 17 hours. I used TestMem4, MemTest86+ v1.40 and the Windows memory diagnostic from the UBCD. I attempted to boot to my DFT HDD diagnostic CD but it failed while booting and returned to the boot screen. I've also swapped a different power supply into the system with no difference.
I've attached a .zip file containing 10 minidump files.
While you experts are pondering my problem, I'll be scanning the HDD for malware while slaved to another PC. It should be available for troubleshooting in an hour or so. Mini092410-03.zip
