edit: I still hope this helps someone, but the problem is back. Everything was flying after the driver was installed, but after the computer went to sleep, the incredibly frustrating problem is back. Even typing this is causing annoying lags. I have nothing installed except Firefox and Avast I hope this helps someone else! I installed Windows 7 RC1 32 bit on a clean, formatted partion and install took hours. A problem I see quite a few people having. (I've used the same disk to install on my laptop and it's running great and took 30min. tops.) After installation everything appeared to be running fine, except windows for all applications would work and then stop responding for up to four or five minutes at a time, regardless of what applications were running or installed. I tried installation and setup with a zillion different configurations based on many great suggestions from this forum. (reghakr is the MAN by the way) At last I've solved my super frustrating problem, and it was so simple - In Device Manager there was an unknown device. I selected it and checked the details tab and the value was ACPI\AWY0001. I went to the below site AMD ACPI/AWY0001 Driver Summary downloaded the driver for free, unzipped it to my Documents folder, and then installed the driver. Without even a restart, my machine is FLYING again. It's the driver that controls Away Mode, and it was preventing programs from waking up properl even when they were only idle for a second.
