So this all started last night, I was playing World of Warcraft when my computer just froze, i had to manually restart it. My computer freezes often, it used to be every 5 minutes until I bought a table fan and have it blowing into my computer, it now only freezes once or twice every day. When my computer came back, everything was normal, so I started WoW again, and 1 minute later it froze again. This time when I manually reset it, it came to a black screen with writing on it, this is the first time i had ever seen this on my computer, so i left it for a couple minutes, it did not change so i manually reset my computer again. This time it starts up, everything sounds perfect, it goes to the MOBO screen, which is normal, then it goes to a black screen with a flashing bar on the top left corner. As a bar, I mean ___. I can't get into safe mode, if i press F8 at the MOBO screen, a window pops up asking me which drive to boot, and if I press F8 on the black screen with the flashing bar, nothing happens.
I would really appreciate any help you guys can give, and feel free to ask for anything that might help you determine what the problem it.
I have windows XP
My MOBO is an Asus P4P800-VM
My power supply is a 430W
Thanks for your help
