I solved my problem with lowering RAM-Speed to 800, but i want to know why 1066 dont run.

Even a new BIOS from TUL Corp. didnt help.

Windows 7 Home Premium (64-bit)

Here is the solution to stopping random lockups in Windows 7

1. Go to Start >>> Run
2. Type in msconfig and press Enter
3. Go under Services and turn off Workstation (you can alphabetize the list to easily locate this service)
4. Restart the computer

Workstation is a network service for accessing network drives - there is a bug in the .dll behind this service which locks up the system. Most home users will not need Workstation service and you can safely disable it (uncheck it under Services in msconfig screen).

Windows 7 x64 Ultimate

I lowered my ram speed to 800 from 1066 even though it was 1066 ram some time ago because the ram got SO FLAMING HOT that i could not touch the heatsinks even with airflow. I knew it would not last long if I left it that way.

Lowering the ram speed will have maybe 0.1% speed difference on your machine in reality so I wouldn;t worry about it.

7 Lockups, just like Vista, but a discovery
One of my main systems runs an ECS RS400A motherboard, a 3ghz P4, 2gb memory, not a screamer by any stretch, and it uses the non-mainstream ATI Radeon Xpress 200 chipset. It runs like a rock under XP or *nix, but ever since the first Vista betas, it has locked up after the Vista boot for only a...
