Hi everyone. I have a huge problem and I'm at the point where I have no idea how to fix it. It all started a couple weeks ago with a Windows update, the kind you have to restart your computer. I fell asleep watching a video on youtube, and when I woke, my computer was frozen, sound was glitched like a skipping cd, and the prompt was up to restart my computer for the updates. So, I restarted and once back to my main screen I checked for the update that I supposedly needed, but couldn't find it. Ever since then, my computer has been freezing up/crashing/blue screening at least every hour.
It was at least tolerable until yesterday. Like usual, it completely froze so of course I held down the power button to restart it. It loaded the bios menu( I think that's what it's called, with the system recovery options, boot manager, etc.) then after that it came up with a black screen saying 'BOOTMTGR is compressed. Press crtl+alt+delete to restart. I did, and it repeated this, no matter what I did. I got this fixed fairly quickly with the Vista install disc by repairing the boot drive. Thinking it was all better and fixed, I restarted and browsed the internet for a bit. Not even 20 mins later, it froze. It's still crashing and blue screening along with restarting itself.
I've attempted numerous virus scans with Security Essentials, just the short quick ones. But every time somewhere after four mins in, it freezes. Sometimes during the scan, it just stops and says it can't scan my computer because the anti-virus is not turned on. After this happens, I get an alert that pops up saying my Windows Defender is now turned off.
I really have no idea what to do at this point. I've never ran into a computer problem I couldn't fix and I'm entirely stumped on this one. Here's everything I've attempted so far:
Running in Safe Mode: Everything loads up fine, but it's incredibly slow. I'm not able to perform a system restore as it says it's already running and it will now close.
Defraged my HD but every time it finishes it says it needs to run it again.
I've uninstalled all the most recent Windows Updates, but it changed nothing. I even tried reinstalling them, same outcome.
I've ran TDSS rootkiller but it showed nothing. Along with every other single system scan I've attempted with my computer, they all pass.
I've checked my computer temperature, fans are running fine and it's not overheating.
It all seems to have started with that Windows Update. I know I'm leaving some things out, but I can't remember off-hand. I've tried pretty much everything I know how to do and Google hasn't been much help for me in this case. I'm no computer expert, but I do know how to solve most problems. This is not one of them... Any help would be greatly appreciated as I work from home and can't get anything done with my computer crashing every hour.
After looking through the net all day, I've deleted certain corrupted files and now the freezing occurs less often, maybe once every two hours. I've ran multiple virus scans from different AV providers, came up with nothing. It looks like most of the problems are coming from Windows Defender. It's completely updated but it constantly freezes and says it needs an update. The version says it's the current one, but it says it hasn't been updated since January of 2013. I can't find anything that specifically coincides with my problem. I also realized I entirely forgot to post my systems specs. Not really sure what I need to put here, so I'll list as much as I can.
