__________ _________________ ______________ _________Problem:
My computer restarts by itself at random. It restarts when I am playing games, and it also restarts when I am doing nothing at all.What I did to attempt to fix the problem:
I physically cleaned the computer inside and out. I checked my fans for adequate air flow. My RAM and PSU "appear" to be working fine I presume. My harddrive appears to be fine using checkdisk. I ran every crazy program that promises to fix your computer and I only made things worse. I tried replacing RUNDLL32.exe because it appeared corrupted, but who knows at this point NOW the problems are compounded:
I have video card driver issues and no sound is coming from the speakers. Error Messages:
*Windows has stopped "Run a DLL as an APP" to prevent damage to your computer.
*Blue screen-- NV4_disp.dll physical memory dump -- address BD161846 base at BD012000
*Sigma Tel high definition audio codec not working properly. Faulty Driver
I think I have screwed everything up and I need some help.
thanks for everything in advance!
