I have a dimension 8300 (spare me the laughter and snide comments, please). lately, it refuses to boot windows. it keeps giving me a message saying one of my hard drives was not detected. I have 3 hard drives: 2 160gb pata drives and 1 750gb sata drive, drives C, D, and G. it keeps saying it can't find my D drive and sometimes my C drive as well. the g drive is the boot drive, so I usually keep going with the boot procedure. Once it gets to the win xp screen before the account log-in screen, it just sits there. One time I let it run for >30 min and still nothing. this happens even when using safe mode. I've been trying to figure out what the problem is and fix it. after all, a computer that won't boot the OS is just a useless heap of metal and plastic. I recently added 2gb of ddr1 pc3200 ram, so perhaps that's the cause? in addition, for a while before the computer completely failed, I would get BSODs every time I tried to wake the computer up from hibernating. apparently this was due to a driver issue, maybe the graphics driver. I can provide the detailed BSOD error message if that helps. any advice would be greatly appreciated. thanks!
