A friend called me and said her computer wouldn't go past windows 98 opening page for a week, and now it won't even go that far; it only goes to the page with PCI Device listing. She brought it over and I opened the tower and the fan in the power supply was running, but the CPU fan wasn't and everything was black inside with oily grit. I checked the cards and cables and cleaned it inside as much as I could, and the fan started running, but windows still wouldn't go further. I could open BIOS, but not safemode. I tried running the WD utilities disk to test the HD, but it wouldn't run from the floppy; neither would the startup disk or the system disk. I have a windows 98 cd and it wouldn't run either even tho' I switched the setting in BIOS. The computer is an old PC166 with EDO memory and a WD HD. Is it worth taking the HD out and trying another one I have that works? I have some EDO around too and a sound card, but no video card. Or is the computer dead?!
