|As Richard said, XP & 2000 are out...you don't have enough RAM. Win98 or WinME are your only options. The BSOD is most likely caused by bad RAM. Do you have a floppy drive? Download memtest86, unzip it, open the folder, double click on INSTALL.BAT & follow the instructions (have a floppy disc ready to go)|
Once you've created the disc, boot off it & let the test run for at least once complete series. If any errors are found, the RAM is most likely bad & will need to be replaced. To be sure, try removing the RAM, cleaning the contact edge, then running the test again.
