Im not sure whats wrong i was having the same probs so i transfered all my stuff to my d:/ drive and formated c:/ and clean installed which has always worked in the past.

it always resets about 4-6 hrs after its rebooted.

Hi,

One minidump is insufficient to find out the culprit. The prelimary finding is faulty ram. Attach more dumps here.

Suggestion
1. Check the temperature of the CPU and make sure that it is not overheat (ie temperature < 60C)
2. Reseat the memory stick to another memory slot
3. Downclock the ram
4. Clean the dust inside the computer case
5. Make sure that the ram is compatible to the motherboard
6. Check the bios setting about memory timing and make sure that it is on
If it still crashes, diagnostic which memory stick is faulty
1. Take out one memory stick. If windows does not crash, the removed memory stick is faulty.
2. If you have only one memory stick, replace the ram
