Hello. I have a a Intel Pentium 3 computer. The other day it crashed due to viruses and pop up ads taking over it. I ran various spyware and adware programs nothing worked. I tried going into safe mode to see if i can fix from there but can't because the computer shuts down and reboots in the middle of me tryingto get ito that mode. So i decided to start from scratch and reinstall windows 2000, the problem is that it does'nt load all the way, only half way then the computer shut down, and rebooted. So i tred again and the same thing happens . It gets to a certain point in the loading process then shuts down again. Sometimes i'll get a message saying there was a hardware confuguration problem, other times it will just shut down ad reboot. Do i need to erase all on the hardrive first ? if so how ? or what might the problem and solution be to get windows installed? Thanks for your help!!
