Refreshing

[I.am]

Try one thing for me. Go to Start> Run > regedit

HKEY_CURRENT_USER > Control Panel > Desktop

On the right pane you will see some values. Adjust the middle scrollbar to the left so the right pane is shown clearly. Now try to take a screenshot of this image and past it back. I want to see how much is each delay on desktop functions. Dont know if that'll do anything but lets try it out.

You didn't say what your CPU usage was when this occurred. That's more likely the problem.
With a few of the crappy new hot fixes from MS, there is again a problem with the way the kernel and CPU resources are managed. There's a good chance that a lot of applications and services refuse to open or close and total threads will show some rediculous number.
You won't always see what's happening, but it may feel like you're back on a pentium 2 instead of your 1000mgh.
It'll feel like a bad hard drive at times, bad ram at others. You may be tempted to replace the CPU, all of this is thanks to the potheads at MS who keep pumping out shit code to "repair problems" instead of doing it right the first time.

A few things to try-

Shut down and clear CMOS. In the BIOS, reset the time and date and select "optimal settings", save and restart.
when windows is up and running, go to a command prompt and type >chkdsk /r

Select "Y" , enter. Close the command window. Clean all temp files and history, disable any "go back" programs or system restore. Defrag with the windows defragmenter, twice if any red shows.

Restart and let the checkdisk complete. It will reboot if any problems are found. When windows restarts, check task manager again and compare the results.
