My "good" computer is having problems starting up. A few days ago I had to erase the hard drive and reinstall windows due to a SERIOUS malware infection that couldn't seem to be erased any other way. I ended up being able to use my computer for games and other things afterwards, meaning everything seemed to be running smoothly.

Today I started it up. It went to the screen that was all black and said something like "Windows stopped working unexpectedly last time" and asked me to choose safe MODE, and the other two types of safes modes and "last good config" as well as "start windows normally". If I choose any of the sade mode options, it runs through a bunch of text (Hopefully you know what i mean, i can't recall the long strings of text) and then just hangs there... doesn't startup. If I choose "last good config" it also hangs on that very black screen, doing nothing, even the number at the bottom that counts down until windows starts up stops (screen appears to be frozen). Start windows normally does the same thing. This happened a few times, eventually I got it to main screen and was doing normal things (Internet) when the screen flashed blue screen of death and then restarted. Then this happened again and it's not working.

This doesn't make sense, it was working just yesterday PERFECTLY with no bad happenings. I remember in the past it would flash the BSOD and I would freak, but it would restart normally (It didn't happen often).

All my drivers are up to date, as I have checked that yesterday and made sure everything was fine.

Also note, something in the tower is making a strange buzzing noise when it is running.

I would really appreciate any information as to what is going on with this computer.

PC info that I can remember (I am not computer savvy, and because I can't start it up to check). 1GB RAM, Geforce 6600 GT GFx card, good processor (can't remember the NAME, it's not old though) and power source working fine (Had checked PC Wizard just yesterday, no abnormalities).This just in. Computer is still being funky. I'm on it right now.

I was just sitting here messing with my screen, I hit "Recall" option on it, whatever that does... then restarted the computer seeing as maybe I would give it one last shot.

I started in "Last good config" it startup up and at desktop gave me the following two windows both titled "RUNDLL"

C:\Windows\System32\NvMcTray.dll

and C:\Windows\System32\NvCpl.dllBoth Nvidia related. Don't know what "Recall" option is and have no idea exactly what message(s) you are getting.Bothe of those are related to the nVidia Control Panel APPLET...
Try booting into safemode by tapping F8 repeatedly upon powering up and before you see the splash screen...
Then re-install the nVidia drivers from the original CD that came with the card...newer Drivers are not always better Drivers...and this may be the cause of the issue.
