I have a Dell Inspiron 5100. I recently upgraded to 1 MB of RAM in 2 512MB PNY Modules. The system was fully updated w/ XP SP 3 and was running fine. Last week, I installed a Belkin Wireless G Notebook Card, Model F5D7010v8. On reboot, I would get the BSOD w/ the stop code 0x0000007E. I would get it for 3 or 4 boots, then the system would boot and run fine, then 3 or 4 boots, and so on. When it would boot succesfully, the Belkin notebook card worked flawlesly. I disabled the Belkin drivers, and had no problems w/ any BSOD occurrences. I contacted Belkin, they told me they didn't have drivers for SP3 and recommended I roll back to SP2. I did that, and re-actived the drivers and on the next boot got a PAGE_FAULT_IN_NON_PAGED_AREA message with win32k.sys. I re-booted, and the system booted fine. I was in the middle of downloading XP updates, and I got another BSOD, this time with the stop code 0x0000008E.
I have a Fujitsu 30GB hard drive. I ran the built in XP test and it passed. I downloaded and ran Fujitsu's HD utility and passed both the short and extended test. Memtest86+ v1.7 is currently running from an Image CD during boot. So far, it has completed 2 passes w/ no errors found. I'm waiting for it to finish at least 7 passes. I attempted to update my BIOS from Dell's support website, and they have an updated BIOS for my system, but when I attempt to flash it, it will not allow me to continue and tells me I have an unsupported system.
Any other suggestions on where I can look, or possibly on known issues and work arounds w/ the Belkin drivers and Windows XP?
