I got my HP Pavilion dv6000 laptop running Vista Ultimatge back from the shop on Wed. They installed a new hard drive, Windows updates (including Service Pack 2), and AVG 9.0. On Wed., the cursor froze up a couple of times while I was on the Internet, and I had to manually shut down the computer. I also noticed that when not in use, the screen goes black except for a floating Windows symbol. The computer had not done that before. Thursday morning I found the laptop frozen up with the Windows symbol in the middle of a black screen. Had to manually shut down and reboot again. This time the computer screen said that CHKDSK was checking a disk for consistency, and something about NTFS. Mostly normal operation afterwards. Again last night the computer froze up with the Windows symbol on a black screen. Again manually shut down and rebooted.

So far I've done a system performance report, which says AVG is not recognized as functioning. I've looked at the Event Log, which lists several warnings such as: ntaskrnl.exe, iexplore.exe, and svhost.exe are using up too much system memory; also some delays resulting in degradation; also NVIDIA is using too many resources.

Does anyone know what's wrong or what to do? Thanks.

sounds like they have a screensaver when windows goes to sleep.

to change that go to. start - control panel - (classic view) - power options

choose when computer sleeps (left pane) I choose never.

Thanks, Kenny1111! I have given that a try.

The power changes didn't help. The computer still is freezing up occasionally when online, but every time it's left idle for a while. All of the blue lights are on, but it won't wake up when I tap the touchpad. Control/alt/delete does nothing. Just got off a chat with HP, and the person said it was "an issue with windows partition" and with all .dll file formats and said I needed to do a system restore. I know the repair people backed up everything before they changed the hard drive, and when I got my computer back all of my files, pictures, etc. were on it. I'm really frustrated and don't know what to try next.

Thanks! I'm still struggling with this. An online chat with HP tech said it was an issue with windows partition and all dll file formats and that I needed to do a system restore. I called the tech guy who repaired my laptop this morning. He said to uninstall AVG 9.0, download AVG 8.5, and run the disk degragmenter. AVG is done, but the defrag ran for a couple of hours, then the computer froze up. Called the tech guy back; he said shut it down and try Defraggler. Downloaded Defraggler and ran it for SIX hours before the computer froze up again. After shut down and restart, no record of any defragmentation showed up! Ran "analyze" on the Defraggler and it said there were 43 fragmented files. The tech guy said it might be something with the hard drive controller on the motherboard, but that the motherboard was an expensive thing to fix. Can anybody help? I'm ready to scream!
