Windows 7 Win 7 64 Bit Freezes after startup

[Antracith]

Hi!
I have an odd issue and I have tried to find any usefull info in the event logs already.

What happens is this:
When I boot my system, the system freezes when loading startup programs. I see wallpaper, taskbar and everything but it freezes there after about 20 seconds UNLESS i move the mouse constantly. So IF I move the mouse constantly when the system is loading then it is all fine and I can use the system for hours without any issues. This happens every thime I boot the system and don't move the mouse. The event log views a Kernel-power error but I believe this is the result of the forced shutdown I have to do when the system freezes. Note that pressing Ctrl+Alt+Del does not work, nothing works, it is frozen.

Any help is much appreciated. System specs can be shown below.

Motherboard: Asus M4A785TD-V EVO
CPU: Phenom 550 BE (not OC and not Unlocked, can be unlocked however...)
RAM: Corsair XMS 3 3 x 2 GB (6 GB in total)
Video: Ati HD4850
PSU: Corsair HX620
HDD: Seagate Barracuda 7200.12

What programs do you have running on startup ? Boot in F8 safe mode and see if it still freezes. It can be a driver issue. (e.g. mouse, keyboard)

Update your system and drivers.

Do not force your system to shut down, wait up till it unfreezes, then reboot and attach your log file here.
