Okay I have a problem with my computer. Okay the computer at first was overheating and shutting off and there were problems. Now me being the lazy bastard that I am just stopped everything that was unnecessary from using power like the cd drive and floppy drive and all of that junk. I don't know if that affected anything but my computer stopped overheating. Okay next on a couple of weeks later my computer shuts off permanently and I just think that it is the same thing from before and try to cut it back on later. But the problem is when it comes on that screen that says the computer power supply was interrupted and blah blah blah do you want to start normally or in safe mode etc etc. So when I make my selection the computer starts to come on but then a blue screen comes up and as soon as it comes up it shuts off and restarts the whole process again to just return to the blue screen and shut off. Now I opened up the case and cleaned everything out with a can of air and checked all the parts. Everything looks okay from what i can tell. But it still does that whole come on select option, blue screen flash and shut off. I don't know what to do and was asking for help. I have one of those HP computers out of the box and it is about two years old. I am also running windows XP. So if anyone can please help me please do so. Pretty please. Oh and when I try to boot up from the cd so that I can fresh install windows I get this error message ==> PCI Parity Error on Bus/Device/Function 00F0h. So if anyone can help me please I would really appreciate it.
