Machine running slow even after Vista just installed.
Posted on 2009-04-25
Had a problem with a laptop starting about a week ago. Suddenly, it started running slowly with DWM consuming about 90% of the CPU. (I posted another question about it but closed it after it suddenly went away.) After a few reboots I found that about 60% of the time the system would crawl, but 40% it was fine. However, in SafeMode the system runs fine.
I gave in a decided to reinstall Visa. Even just after Vista has been installed the system is crawling. I turned off all Aero features thinking it was that but still no good. I look at the Event log; no hardware errors were clocked but in the performance subsection I got the following error:
EventID: 500 Opcode: Video Memory Degredation.
To try to rule out the video card, I ran Microsoft's Performance test. (The one that rates the system.) The system scrored 1.1!!! The system had always scored about a 4.0. Also, it was the CPU that killed the score. It was a 1.1.
The only thing that makes sense to me is hardware. But, my experience has always been hardware either works or it doesn't. Except when heat is a problem. I don't think it's that because the problem occurs at boot.
Thanks in advance for help and sage advice!
