So my computer has been freezing up within five minutes or less after loading up. I generally get an error message such as UMDDFAPI.EXE - application error, with the explanation, "The instruction at '0x8c80d189' referenced memory at '0xfc85c6ft', the memory could not be read". I click on OK and the computer starts to freeze. A blue screen comes up with "Page_fault_in_nonpaged_area" as the error. Loading up my computer again, I check the Tasklist and it says that a RunOnce program is running. If I try to stop the process, the computer freezes. If I let it run, it goes to the blue screen. I've gone into safemode and done a Norton Antivrus check and it doesn't solve the problem. I've also tried the Spybot and Adaware programs. But maybe the problem isn't a virus, but something wrong with the memory? I have no idea.

Without the exact information about the page fault,it is hard to diagnose the problem. In most cases, this kind of error message will happen if you have bad drivers or a hardware malfunction. In your case, an educated guess would be bad RAM. If you have two RAM cards installed, removing one at a time might tell you which (if either) is the culprit.

You can check your memory by downloading a program called Memtest86.
It is a free download. It requires that you create a boot disk.
I would recommend that you let it run overnight.

http://www.memtest86.com/

This will let you know if you have a problem with the memory(RAM) in your computer.

I found no reference to the file - UMDDFAPI.EXE.
Perhaps you should post a log in our HijackThis Logs and Analysis Forum

Before you do, please read: -How to submit a Hijackthis Log

Post again with the results of the memory scan.

Good-luck,

JC :thumbsup:

It's not a memory problem after running the memtest. I've also downloaded updated versions of Adaware, Symantec, Microsoft Anti-Virus Beta, and Spybot. Yet, even though I find stuff, nothing is getting rid of whatever is troubling my computer.

Well we have eliminated two possibilities. The next step would be to make sure you have the latest drivers for your video card; you may find these drivers at the manufacturer's site. Have you recently changed any hardware?
