Windows 7: Some programs won't run/install, explorer slow, ect.

It was all fine until yesterday. I copied over a game from my laptop the night before (I just installed 7 on this computer recently, was copying over stuff from my laptop) and also finished installing World of Warcraft and not long after I turned off the computer.

The next day I switched it on and didn't notice anything at first but some programs wouldn't run (Winamp would have a blank space where the music list normally is).
I tried installing some virtual drive programs such as magic disc and power iso which I usually use for isos I rip onto the computer (I lost some discs before so I've been doing that recently) but the magic disc programs wouldn't run properly and power iso wouldn't progress during its installation.
I tried installing some anti spyware like AVG and Avast (Spyware doctor detected 300 odd tracking cookies that appeared in the past week I installed, way more than it did with my vista laptop) but they would just either not respond (and then pop up with a message saying it took a while and wouldn't respond) or just not even progress when it was installing (on the part where it begins putting down files)

Explorer itself is slow and takes a while to load when on "My computer" and usually wouldn't display USB drives. Once it did but it didn't actually open it up when I clicked on it and prevented the window from responding.
I have used task manager to close all these down when they wouldn't.

When I tried switching off my computer it just stayed on the logging off/shutting down screen. I tried leaving it overnight, expecting it to finally switch off but it only ende up going into sleep mode (and popped up with the log in screen when I waked it up)

I have switched the computer off and on a few times but its still the same.

I also got the disc I used to install and tried to repair it but it wouldn't boot from the disc when I switched on the PC and when I opened it up and ran the setup file, it came up with the usual "are you sure you want to run this" dialog and didn't do anything.

I am using build 7100, any help would be great

This just started happening to me with Windows 7. Pretty much the same thing. Anyone else experience this? Any fix?

You mean it just started happening ?

Or were you doing the same thing;copying files?

Aleitheo,

If it were me, I would run a System Restore back to a point prior to when the problems began.

An online backup was in progress to iDrive. I was also trying to access a Mac drive through MacDrive 8. The MacDrive program stopped running, and then everything seemed to lock. When I rebooted, that's when the trouble started.

I tried running System Restore and two are available. One was just prior to a Critical Update and that was a day before the crash happened. I tried restoring that but it didn't help. I only have one other Restore point from two days ago, but when I try to run it Windows says the file is corrupt.

I have a very large collection of DVDs from Region 1, 2, 4 all genuine (no bootlegs). I have AnyDVD running on my Win XP pro system computer. My new Dell Inspiron 1470 has region lock on it. I installed AnyDVD but is does not seem to run. Is this normal? Otherwise, is there a way to turn off the Region lock?

I joined this site months ago and its now that people are posting in it, when I uninstalled 7 ages ago?
