Bios Worm

[JV268]

I have a question for you. My computer is black screening. Can this problem be caused be a bios worm? If so, what do you recommend on how to remove the worm? My motherboard is an ASUS M4A785T-M and I'm using a AMD Athlon II x4 640

When did the problem start happening?
Have you made any recent changes to hardware or software?
Do you see the POST screen when you turn on the machine?
Any beeps coming from the motherboard when you turn the system on?

Pre-Built Brand & Model Number
Custom Built-Brand & Model of RAM-Graphics-PSU.
I doubt the problem is in the Bios.

JMPC: It happened weeks ago and no i didn't made anything recent hardware changes and yes the pc boots until it black screens usually 5 minutes after log on. Then after when it black screens it takes a long time until it gives me another 5 minutes of use.

Ultra PSU's are very poor quality.
Patriot RAM has been known to be flaky.
