Hi I was just using my computer when it just switched itself off randomly. Now everytime i try to turn on the PC it just turns off and turns back on again. The steps are: 1. Turn computer on. 2. Light on the Computer comes on. 3. Switches off. 4. Switches back on. 5. Switches off again.... It keeps repeating that until i turn the computer off at the mains. I'm not really sure what the problem is and thought you guys might be able to help me .
