misq Posted September 20, 2010 Share Posted September 20, 2010 Hi there, Currently I'm unable to boot my PC. When I turn on the computer, all things seem to be working for a few seconds (fans spinning and harddisks rotating) and then the system restarts itself. This process repeats continuously. I unplugged all power connectors and test the PSU using the "Paperclip Test" method outlined by the Tech Support Express and found that the PSU seemed to be working (the PSU fan was spinning anyway). Then, when I only connect the 24-pin ATX power connector to the motherboard, the PSU again seemed fine (fan spinning continuously). However, when I connect the 8-pin EPS12V connector to the motherboard (with 24-pin ATX power connector connected but not any others) and turn on the computer, the computer again restarts itself every two or three seconds. The fans of the PSU and the CPU all start and stop at a 2-3 second interval. I wonder whether there is a problem with the PSU's EPS12V power supply? Or is it the motherboard's problem? By the way, the system is only about one-year old and the motherboard is Asus P5Q3. The computer is not overclocked and it's mainly used for word and graphic processing. Thank you in advance.

If possible I would test the PSU in a different system and see if you can duplicate the same issues. If all else fails then we can certainly try replacing the unit for you.

misq Posted September 20, 2010 Author Share Posted September 20, 2010 Thank you RAM GUY! I'll find a way to test the PSU on another system. Will keep you posted. Link to comment Share on other sites More sharing options...
misq Posted September 26, 2010 Author Share Posted September 26, 2010 Just thought you'd like to know that it turned out to be the motherboard's problem. :) Link to comment Share on other sites More sharing options...
