Friend has come to me with a computer problem. His computer was getting to the windows splashscreen and then rebooting. On trying to enter windos through the command prompt, he got a blue screen of death, VFAT error. Soooo...he tried to reformat his computer...didn't work. When the computer goes to reboot during the installation of windows, it hits that splash screen and reboots...and reboots...and reboots...and...well, you get the picture. Since that didn't work, he cleard the BIOS (with the jumper on the m-board)...tried reinstalling windows, same thing. This is where I come in...he wants me to figure out what needs to be done to it. I'm no longer concerned about losing data on the HDD (since he reformatted it already). Noticed that the power supply is doing wierd things. When the computer is off, the light on the FDD remains on sometimes, the hard drive seems to run a little loud at times. I wasn't able to determine what speed processor he's running, but it is a pentium-class socket 7 processor with 64 (I think) MB of ram and he's trying to run Win98SE (same OS it's been running since he purchased it in '99). He told me that he replaced the power supply just about 6-8 months ago. I tried putting another HDD in his computer to see if it would work (I've got an extra 6.4 GB)...no luck. If you can offer any suggestions as to what he (or rather I) should do, I'd greatly appreciate it. If there's any other information you need, lemme know and I'll see what I can get. Thanks for your help!
