Hello, My computer has been randomly crashing and complaining about memory problems on a blue screen a lot lately. I've tried all sorts of methods to fix this suggested by friends and other people, I've also run all sorts of antivirus/anti-spyware/anti-adware programs prior to this, but to no avail. I finally decided to simply format my hard drive and start fresh. However, when I finished formatting and tried to reinstall windows, after the completion of the first phase of installation the computer restarted. It was supposed to do this, so this is normal. But then after it rebooted it said "Installation is re-initializing" or something like that on the lught blue Windows XP installation screen and then... The screen went black and this large rainbow-colored blob just floated from the right side of the screen to the left. And then the computer restarted and did the same thing again. And it keeps doing that every time until you turn it off. What could this problem be and how can I fix it? None of my friends have ever even heard of a problem like this...

its could be 1 of 3 things bad hard drive bad RAM CPU overheating

How do I find out which one it is? And what do I do? It can't be overheating, I've tried leaving it off for a few days and trying again.

identify the make of your hard drive and goto their website, download their diagnostic tools download and run memtest86, it can be found using google
