Computer Problems PLEASE HELP


Solid State Member
Ok, i have a custom built computer with a build in GeForce 8100 (i know sucks) and a 550 watt power supply. Anyway, my monitor ALWAYS just goes all crazy colored and my computer freezes. And alot of the time it will do it non stop whenever i turn my computer on within 2 minutes. I dont really know how to explain it, somedays it will run fine. Other days you cant even open internet without it happening. I was thinking it was my graphics card overheating but i took my side panel off my case and put a fan blowing in and it still does it. so i don't know what it is. And i am running windows 7. I will put a pic up next time it happens. Usually it runs ok at night when it is cooler out, but sometimes not at all. :confused: :confused: :confused:
