This has been happening for a few months now. It's not the screen saver. In fact, I use the screen saver to let me know how long I've been away from the computer. If I see the screen saver, I have to touch the mouse pad or do something like minimize a window in order to prevent the computer from freezing. If I need to get away from the computer for a while, I have to log off of my user account because it doesn't freeze when I'm logged off or in safe mode. And occasionally, instead of freezing, I'll get an error message that says, "Host process for Windows Services stopped working and was closed."
At first, I thought it was a game I have (The Sims 2). On the same day this started, the game froze and an error message came up and I had to "terminate" the game. I remember the error message had that word in it and that's all I can recall of it. I tried uninstalling the game and downloading patches for the expansion packs and after that, the game ran fine, but the computer would still freeze if I left it idle. It's a mystery to me as to why this all started to happen.
I checked Event Manager once and got this:
"Log Name: Application
Source: Application Error
Date: 6/20/2009 4:44:43 PM
Event ID: 1005
Task Category: (100)
Windows cannot access the file C:\Windows\Prefetch\AgGlUAD_P_S-1-5-21-445318638-3710151374-614389321-1000.db for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Host Process for Windows Services because of this error.
Program: Host Process for Windows Services
The error value is listed in the Additional Data section.
1. Open the file again. This situation might be a temporary problem that corrects itself when the program runs again.
2. If the file still cannot be accessed and
- It is on the network, your network administrator should verify that there is not a problem with the network and that the server can be contacted.
- It is on a removable disk, for example, a floppy disk or CD-ROM, verify that the disk is fully inserted into the computer.
3. Check and repair the file system by running CHKDSK. To run CHKDSK, click Start, click Run, type CMD, and then click OK. At the command prompt, type CHKDSK /F, and then press ENTER.
4. If the problem persists, restore the file from a backup copy.
5. Determine whether other files on the same disk can be opened. If not, the disk might be damaged. If it is a hard disk, contact your administrator or computer hardware vendor for further assistance.
