Computer won't turn on. PSU clicks then pings. Graphics card fans only spin for a few seconds.


I hope someone can help me here because my computer doesn't want to turn on, I have pretty much tried everything. A few days before it stopped turning on a few messages appeared showing Asus anti-surge was triggered, but I checked the voltage readings and everything was normal. I replaced the PSU to see if that was the cause but it made no difference.

The RAM, PSU, CPU and graphics card are not at fault here because I've installed them into another computer, using a different motherboard, and it starts and boots up perfectly. I had ruled it down to be an issue with the motherboard, so I purchased another one but that didn't fix the problem either.

After installing everything back into the original case I've attempted to turn it on and noticed a slight click and then a ping sound coming from the PSU. This happens with both the old and new PSU's. The fans on my graphics card also spin for a few seconds and then stop.

I didn't swap over the CPU cooler or hard drive and I used different cables when installing the parts into the other computer. So could a problem with any of these cause my computer not to start?

EDIT: No luck with those options. I've reset the BIOS, removed the hard drive and pressed the MemOK button but its still not working. Also tested the power supply in the other computer again and it starts with no problems. :??:

  1. You may want to wipe your BIOS and make sure that are you haven't got any issues in your BIOS but to me that sounds like a dodgy PSU, I suppose that possibly the HDD has died and is stopping the PC from loading up, which is an issue I have faced before. You could take the HHD out and see if the PC turns on. Is there any chance you could post your PC full specifications including both of the PSU's???
