If I understand you Shaddy you wish to restore to back before the issue of 'not responding' but after the tech did his work. If there is a restore point created in between those 2 dates then yes you can. However if there is none then you cannot restore to that time frame. This is why I like to suggest (but often forget to do myself sadly) that people should create a restore point before making changes to their computer. Then if those changes do not create the desired effect the computer can be restored to before the changes made. On the issue of 'not responding' take a look in your Event viewer next time this happens. To do so click Start click Control panel click Administrative Tools click Event viewer Now you have a new window, look on the left site and click on System so you can view the results in the right side. Scroll down if needed looking for red error marks or yellow warning marks. Double click on any of these for further information. Much of it you will not understand but there will be a link there and if you click that you will be taken to the Microsoft site and hopefully an answer to your problem. If not then report back here with the error number and any pertinent comments they make.

I remember having this happen to me some time back. I still don't know why, but I booted into SafeMode and was able to do the System Restore. You might give that a try and see if it works for you.

In some cases when a hard drive starts going, there will be a password prompt. With persistance in taking it out and putting it back, you might be able to get in once and salvage what files you need. Otherwise, the HDD is probably toast and what is there is gone

Sorry I didn't mention what I have running. I have WindowsXP. I have Norton Internet Security. I ran Malwarebytes (a full scan). Anyway, I thought if I did a system restore I could install my printer. This is the second new printer I have tried to install. It just continually loops and doesn't install. I removed any printer that had been installed on my computer. Here is the result of my scan:Malwarebytes' Anti-Malware 1.40 Database version: 2670 Windows 5.1.2600 Service Pack 3 8/29/2009 4:06:04 AM mbam-log-2009-08-29 (04-06-04).txt Scan type: Full Scan (C:\:) Objects scanned: 275483 Time elapsed: 1 hour(s), 57 minute(s), 9 second(s) Memory Processes Infected: 0 Memory Modules Infected: 1 Registry Keys Infected: 4 Registry Values Infected: 1 Registry Data Items Infected: 0 Folders Infected: 0 Files Infected: 1 Memory Processes Infected: (No malicious items detected) Memory Modules Infected: C:\Program Files\alot\bin\alot.dll (Adware.BHO) -> Delete on reboot.

I am so computer challenged. Is this what I needed to do? What do I do next? Thank you for any help you can give me.
