Annoying problem PSU or MOBO

post #1 of 2
Thread Starter 
Hi guys.

I have a problem that has lead to consider replacing new parts just because i figue out which one it is and I'v tried troubleshooting. No fix frown.gif
The problem is that when I hit the power button, my PC will turn on but not boot, not even to the bios and the power light doesnt come on. The fans spin but increase and decease speed in a 1 second pattern. If I give my Case a bit of a knock, the power light comes on and it boots up. Its my current PC in my sig. Im pretty sure its my PSU as my friend had a problem with his psu which is the same as mine. I just find it weird that it boots after a knock. Its not the HDD because I tried a boot test with certain componants plugged and unplugged. Also checked the power button with a jumper and a different power button from another case and still the same problem.

I was thinking of getting a ASUS M5A97 PRO mobo (Yes amd tongue.gif) and can someone recommend a 600+ watt PSU that isnt more than $150, Im really liking the corsair. thumb.gif

My current PSU is a Gigabyte something 585 watt. It squiels and the fan is noisy mad.gif

Anyway. Should I just replace or has someone had this problem before or any possible explanation?

Dont be affraid to get technical, i know my computer jargon tongue.gif

thanks

Follow this link to test your PSU http://www.overclock.net/t/96712/how-to-jump-start-a-power-supply-psu-test-a-power-supply-and-components

It'll show you how to jump start your PSU when it is not connected to a mobo. Make sure you do connect a hard drive or fan to it, so you can see if it's actually working or not.
