OK. The issue I have is that (I have Windows XP), well, my computer will work sometimes, as normal. It will work for a while...5-20 minutes, then it will reboot itself, without a shutdown. The black screen comes on, the one that first shows up when the computer ON button is first pressed. I think thats the Bios screen? But,then that the computer wont load past that which means it doesnt even read the processor or the ram or anything.
At this point I would restart the computer by holding down the computer button for 5 seconds then it turns off. I then press the button to turn it back on. The first thing that pops us is that black screen again and sometimes it doesnt even show cleanerly. All the font is flashing (kinda like the matrix) but, only where the text is.
I have already takin out the hard drive to keep all the files that i need from it. It is now back in the computer and windows is running however, at any moment, it could cut off and do it all over again. Any ideas on what this could be? I was going to reinstall widnows but, it never even gets to the part to where it can read the drive....im lost.
