I'd appreciate any help that anyone can provide:
The problem started slowly, and gradually got worse.
When I turn my computer on, it doesn't seem to do anything - the hard drive and CD lights come on, the fans come on, but the startup process doesn't seem to happen. Then, after 5 - 20 minutes (if I'm lucky), it may begin the startup process (ie. the Windows XP loading screen). However, the keyboard may or may not work, and if it does, it may only work for a while.
I've tried new keyboards, mice, and monitors to rule them out (everything else like printers unplugged). I've tried it in different outlets also to rule that out. My laptop computer hooked up to my keyboard and monitor works in the same outlet.
I took the computer in for repair, and they found nothing since it worked perfectly fine for them.
So I took it to a friends house, where it didn't work at first, then did after a while.
Still didn't work at home.
Took it to another computer repair place, where it worked fine.
Does anyone have any ideas?
Someone suggested the power supply ... but why would the computer only not work at my house and occasionally at my friends?
(Pentium IV, 1.8 Ghz, 512 MB RAM, Win XP)
Thanks in advance.
