Is it possible my mother board or power supply is bad or dying?
I have a computer that was having a lot of problems so I tried to reinstall windows XP. Due to several problems I pulled the HD and installed it in a external case and formatted the drive and reinstalled it. tried to load windows again but it took over a day for the files to copy over. I thought it was a bad HD so I put in a new HD and had the same problem. However once it was installed the video resolution could not be adjusted. I thought this was a problem with my reinstall disk so I overwrote everything with Ubuntu and had the same slow loading. Now Ubuntu starts to load but then it takes a very long time to boot and then everything moves slowly (for example I move the mouse and about 15 seconds later the screen registers the change). any ideas as to what is happening?
