My first thought was to update my sound drivers. I did that, to no avail. Updated video drivers next. Nothing. Then I realized that it was taking forever to boot. It always took longer that I thought it should on this PC, but now it is in the several minute range.
At that point I started thinking it might be my hard drive. I ran check disk, but it froze up and I had to go back to previous config to boot at all. All the SMART data shows to be good. I also ran HD Tune. It all looked good. I have ran multiple anti-spy tools(Spybot and Malwarebytes). I have scanned with antiviris. I have not yet tried pulling RAM sticks.
I'm just wondering what ideas others may have. I know that this could possibly be pretty well anything. What would you suggest trying first though? My CPU is an Athlon 64x2. Four gigs of RAM. Video is an ATI 2600HD. Oh, and the sound card is on-board. Any help or suggestions would be appreciated. I'm considering formating, just to see if it helps. I did have a pretty bad infection of Virtumonde a bit ago. It took running Malwarebytes in safe mode, plus Hijackthis to get rid of it. It seems to be gone though.
