Weird problem is happening with my computer... When I turn the computer on it comes on for 3 seconds and then automatically shuts off (I can try this as many times as I want still never works). When I remove the battery from the mobo it and put it back in about 5 mins later, the computer will start and then load to the POST SCREEN saying: Load system with: Defaults Last known Good The thing is if I click default the computer restarts and then turns off (doesn't work after this, goes back to the same problem as above). When I click last known good it won't work at all. I just recently took my water cool out and I was having this same problem before, but when I would click last known good it the cmos would go back to 2.66 GHz OC with all the other settings I had and would work fine. Unfortunately, I'm using my stock heatsink now so I can't run the CPU at 2.66 GHz, therefore I can't get the computer to start. What could be the problem?
