Hello, I have a Compaq desktop with an AMD Athlon 1.1GHZ 128MB of RAM a 16mb TNT video card and 60GB HDD I tried to reformat the hard drive because I initially had a virus on it - so the only means was to format it. The first time I reinstalled it successfully with a copy of a WinXP Pro cd, that came with a dell laptop of mine. BIG MISTAKE-- the computer tripped out and was asking for authentication. No problme arised yet, windows xp installed, and authentication was the only thing that was being irritating. I commensed to reformat the hard drive with nothing in it except the OS installed, with a different copy of WinXP that did not come with my dell laptop. In the middle of reformatting, however, about 51% complete, I powered down the computer because I thought it would not hurt the formatting process, so I could take it back to the owner's house and finish up the reformatting process there, and at the same time be able to hang out at their pool. the old idea of "kill two birds with one stone" or something. >_< I feel pretty stupid. I hope you guys don't chew me out now, but yeah. So I tried to turn the computer on again later on to finish reformatting. I pressed the power button and everything seemed to go right, until nothing appeared on the monitor. the monitor stays black, with an orange 'standby' light as if the computer was on standby. P.S. does extreme heat destroy the desktop or the computer parts? i had left it in the car for about 30 mins. to an hour. A day after, I troubleshot the harddrive to see what the probem was, by swapping out a good hard drive and unplugging all the other cards, like the NIC and whatever else was in there. the monitor still refused to respond. Any ideas?
