I bought a Gateway computer in the winter of 2001 I believe and all I know is that it's AMD 1100. It came with windows millenium installed and really did not like that so when windows xp came out, I spent the money and installed it on my PC and it's been okay to this day. Recently the system started to freeze on me in the middle of what I was doing. Hard boot was the only solution to this point and even then it would literaly take about 10 times to boot properly. I thought my hard drive was getting all cluttered so I formatted the hard drive with no complications but as sson as I was done it started freezing on me again. I went ahead and removed, one at a time, all the hardware I had and trying to boot between each of them and nothing happened. I did this until all I had was the video card and one slip of ram. I tried a different video card and slip of ram and still nothing. Do you think I ned an upgrade of some sort for my cpu or my cpu shot or is it the motherboard???
