I have an old IBM desktop(PIII) that started randomly(very randomly..sometimes every 10 mins, sometimes every 45 mins) rebooting..no error, no nothing..just rebooted. I took the computer apart and tried replacing the power supply. I thought that this fixed it as it seemed to work for a couple of hours..I unplugged it for a couple of hours, plugged it back in, and now it would either freeze or reboot as soon as it gets into windows.
Now here's the strange thing. Using IBM's recovery console, I can reformat and reinstall Windows 98 fine. I have done this twice now and it has not frozen or rebooted.
I have tried replacing the memory and hard drive, but this does not help. I haven't been able to replace the motherboard or CPU because it's such an old computer..can't find parts in the store.
I have everything unplugged from the motherboard except the hard drive.
Why would booting into windows cause a reboot or freeze if reformatting and installing windows doesn't? I'm really at a loss here.
Please help. I have been working on this the ENTIRE(!) day. Any kind of help will be great. I'm taking a break for the first time all day but I will definitely be checking this post later tonight.
