I tried upgrading my PC from Windows ME to Windows XP Home Edition on a Compaq Presario with a Athelon 1.3GH processor, 256 MB RAM, 60 GIG HD. After I was done, I tried to defrag the hard drive and the PC crashed to a black screen and then restarted itself. I then decided to do a clean install of Windows XP in case there was some problem with my Windows ME installation that had carried over to the upgrade. I reformatted the hard drive and installed Windows XP again, then I installed the latest Windows XP drivers for all my hardware: Microtek Scanmaker 5900 HP CD Writer model 8220E Soundblaster AudioPCI 128 sound card Creative Modem Blaster v.90 PCI DI5630-5 SanDisk SmartMedia card reader HP Photosmart printer model 1218 NVIDA GEForce2 MX/MX 400 videocard File System is FAT32 I tried to run the defrag program again to analyze my hard driver and it crashed again. I got the blue screen of death because I disabled it from automatically restarting after a crash and got an error message: IRQL_NOT_LESS_OR _EQUAL ***STOP: 0X0000000A (0x7fffffff, 0x00000001, 0x804e414e) Beginning dump of physical memory.
