(Running Windows 7 Home Premium SP1 x64 on a Toshiba Satellite laptop, up-to-date)
I was browsing the internet a few days ago, on cracked.com and topdawgmusic.com (which I'm pretty sure are legitimate sites), no other programs open, when Windows froze, and I had to hold the power button to shut it off. When I turned it back on, it wanted to run a disk check, so I let it. It performed many operations (which I can retrieve the logs of, if needed), but when Windows started up, it only brought up a black screen with a movable cursor. If you just let it sit there for several hours, it presented a BSoD.
Windows worked fine in Safe Mode, so we ran several virus scans using McAfee (which we already had on the computer, the Security Suite), Spybot S&D, SUPERAntiSpyware, and whatever PCPitStop's virus scanner is. All scans were clean, except for several cookies. McAfee's scan never finished, and the scan stalled often, and it started locking up along with other issues (not totally sure what was wrong with it because my dad was trying to fix the computer at this point), so my dad uninstalled it. We then ran another disk check, and Windows started up normally afterwards.
(tl;dr: background of the problem, did several scans, no virus)
Despite fixing that problem, I'm now having issues with some of the Windows services. At first, when starting Windows, only the Audio Service didn't start automatically. If I ran the Audio diagnostic tool, it would start the Audio Service, but that causes the WLAN Auto-Config Service and the Desktop Window Manager Session Manager Service to stop immediately, causing my wi-fi and Aero to stop working. If I tried to start either of those services back up, the Audio Service would stop again.
I'm not sure what I did to cause this to change, but eventually the audio diagnostic tool couldn't start the Audio Service anymore. When I try to start it, my Aero and wi-fi stop working again, but the Audio Service still doesn't turn on. If I open services.msc and start WLAN Auto-Config (wi-fi) and Desktop Window Manager Session Manager (Aero) manually from there, they both turn back on easily, but if I do that with the Audio Service I get error 1068 ("The dependency service or group failed to start"), and wi-fi and Aero turn off again.
note: The faulty services are all set to Automatic, and have been this whole time.
Since I hadn't scanned since my computer only worked in safe mode, I decided to scan with SUPERAntiSpyware again, then Malwarebytes. Both scans were clean.
Because I get error 1068 when trying to start the Audio Service, I looked at the services it depends on, and checked them. All were in order except the Windows Audio Endpoint Builder, which was stopped, which explains the error 1068 I was getting earlier. When I try to start that service, I get error 1067: "The process terminated unexpectedly." Here's the log of that error:
[ Name] Windows Error Reporting
- EventID 1001
[ Qualifiers] 0
[ SystemTime] 2012-03-04T03:58:55.000000000Z
Also, COM+ System Application gives me error 1053: "The service did not respond to the start or control request in a timely fashion." I don't have a clue if this is related to the problem or not, or if it's even a problem, just a random process I tried. And that's where I am right now, out of ideas, google hasn't helped me much.. help please!
edit: My only System Restore point brings me back to the black screen problem.
