P5W DH Deluxe running slow

[Acidic]

ok guys i need some help here.

 

Ive got a P5W DH Deluxe. Lately it has been running extremely slow. The first boot screen takes about 4 minutes to go away. When i press del and go to the setup menu, it takes forever to navigate around, the menu loads slowly. Even the timer in the darwin bootloader that counts down from 8, takes about 60 seconds to count down.

Also I noticed that the windows clock seems to be affected. When ever i restart the clock resets to 1200.

 

Pleaseeee help me with this problem.
