Boot up into Safe Mode with Networking and download the free version of MBAM and run that while in Safe Mode with Networking.

Uncheck the box if it asks if you want to run the Pro trial version.

What happens when you right click on ASP.NET - Properties - and change the Start up to Manual ?

See if this ESET program will reinstate your services http://kb.eset.com/library/ESET/KB%20Team%20Only/Malware/ServicesRepair.exe

Also can you open a Command Prompt as an admin and enter sfc /scannow

Should you need this go Start - type cmd.exe - right click on cmd and select Run as administrator - accept the UAC - type sfc /scannow then press enter and let us know what it reports.

Have you also checked Event Viewer or Reliability history to see if they have anything on these ?

Edit -

For some reason or other the Hyperlink for MBAM isn't working - use https://www.malwarebytes.org/

Once you've cloned the HDD, perhaps one of those rescue disks could get you back in.

For me, I'd prefer an OEM machine to come back the way it was and then if there were any other problems, HP Diagnostics (in this instance) or the factory reset would return it to pristine, providing the HDD is still serviceable.

Wonder if this Repair disk with its auto repair would get you past that https://neosmart.net/blog/2012/windows-xp-system-repair-and-recovery-cds-available/

Edit - Sorry, thought this was a freebie.

The Kaspersky or Hiren's disk should be able to help, which are free.

What happened to the old HDD and why did you have the computer ?

i ran both fixwin and fix wmp but still got the same problem.   

From that link did you also try the Advanced WMP Troubleshooting sub link ?

You can also reinstall WMP by unchecking it's box in Programs & Features/Turn Windows features on or off/Media Features - reboot then go back into Features and recheck its box.

There's also this YT showing how to fool Windows into thinking it hasn't been installed to reinstate it http://www.youtube.com/watch?v=ubyHbleePZs and there's also this ESET Repair Tool that you could try which is designed to repair services following an infection http://kb.eset-la.com/library/ESET/KB%20Team%20Only/Malware/ServicesRepair.exe

The Teredo Tunneling Pseudo-Interface doesn't reinstate on the reboot as other devices do in Device Manager.

I had to fix this a while ago for someone else and before I advised uninstalling, I tried it myself after first creating a restore point and it didn't for me.

Went on a Google run and came across http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/how-to-install-teredo-tunneling-pseudo-interface/754c8f29-3a87-4e77-babd-a69c8910e17e but it may have Dependencies in Non-Plug and Play Drivers which you need to click on View/Show hidden devices in Device Manager to view.

I uninstalled it again and followed those steps and it came back in Device Manager.

If there's anything wrong in Non-Plug and Play Drivers, it will have a yellow alert against it and expanding, scroll down if needed until you come across the item with the alert.

For the most part I think they will reinstate on the reboot or Action/Scan for hardware changes after uninstalling - but always create a restore point first before making any changes - if in doubt, do nothing and post if you find any of them with a yellow alert against them.

Sometimes printing problems can arise because the Print Spooler has stopped for some reason in Services and this should be set to Started and Automatic and it's only Dependency is RPC and if that is stopped, then you would also have a myriad of other problems as well.

What's that other device with the yellow alert in Devices and Printers ?

Running a sfc /scannow as an admin from the command prompt should fix that.

The tutorial for the clean boot walks you through and how to revert to a normal boot, but it's the only method I know of that can isolate programs (except an AV program) to determine if any are in conflict.

The only way to isolate the AV program as the cause would be to either disable it, change it for something else or boot up into Safe Mode with Networking, but Windows Updates don't work in Safe Mode with Networking.

A tech would probably use the same method to eliminate any possible software conflicts, so why pay someone to do what you can do yourself.

Read carefully through or even print out the tutorial so you are familiar with all of the steps and then proceed with confidence.

I was nervous the first time I factory reset my laptop but trusted Windows to know what it was doing, just as MS gives the steps for performing a clean boot.

That sounds like bundled unwanted software that came with another download, so there maybe something else listed with the same date stamp - but glad you were able to find the culprit and thanks for the update.

If it still fails in a clean boot then that will point to your AV or aspects of it such as AVG Secure Search Toolbar if using AVG or you may have picked up a malicious one - so did this occur shortly after downloading anything - in which case your restore points should be able to come to your rescue and have you tried running IE without add-ons ?

Did an offboot sfc.

Windows Resource Protection did not find any integrity violations.

next step is the repair install... will wait for more free time for that one.

Strange.... - but hope you have better luck with the Repair install.

Don't forget to back up your Drivers folders in System32 as the ISO doesn't include any and then you will be able to drop them back in after.

You may want to use the restore point to revert what WR may have done, but have you tried resetting IE to defaults as this problem is usually caused by add-ons.

To confirm, run IE without add-ons - go Start - All Programs - Accessories - System Tools - Internet Explorer (No Add-ons) and click on the home page icon to browse.

The reason Opera is being affected is because other browsers use aspects of IE and if that's buggy, then it can affect other browsers.

When down/upgrading IE because of problems then it's best to reset it to defaults first so you don't take its problems with you.
