Windows 7 Ultimate x64 - Problems with sleep.

I don't know if anyone else experiences this. But the problem is that at random times when i would wake the computer up from sleep (it would be on sleep for either less than an hour or ever 5 hours, time doesn't matter), everything would be ridiculously slow to the point i would have to force shutdown.

It is not a hard drive problem because this happened in the past with my old HD and i recently bought a brand new one. This also never happened with vista.

Basically what would happen is that instead of the logon screen showing up almost immediately like normal, my LCD would stay black for a few seconds and then the logon screen will show up, the password field will be black for a few seconds and then show up, everything is stupidly laggy and slow and nothing will work. My mouse would take 5 seconds to move and respond after every movement etc.

Edit: Event viewer just showed that my display driver stops responding around the time this happened.

 

Even before seeing your edit, a driver or bios issue is what I was leaning toward when reading your post.

Since you upgraded from Vista from Windows 7 I would check with your computer manufacturer to make sure you have the latest bios update and also verify that you have the latest video driver installed for your video adapter. You can also check with your video adapter manufacturer for their latest driver.
