Greetings!! I have a P4P800 SE Motherboard with 3.0Ghz and 1Gb of Memory. I decided to reformat the system and install a fresh copy of Windows XP SP2. During setup the system rebooted randomly and it restart the setup again at 39 minutes left. I tried installed Windows XP around 3 times and the third time it installed. But know what happens is that I log into windows and when I go to install any software’s or even plug in my memory stick the computer freezes and I cant not do anything until I restart. I restarted again and still the same thing. I have changed the Memory on it and the Video card and still the same thing. I have unplug all unnecessary devices such as CDROM, Floppy, Second drive and still it did the same thing. The only thing I did not change is the CPU and the motherboard. Can anybody help me why the computer freezes even when I log in and just click on start it freezes sometimes? Please Help Thanks. P.S. I had WINXPSP2 from before and it was working fine.
