Weak or dying PSU?

post #1 of 4
Thread Starter 
My psu couldn't supply much power, i could say that because when i boot up, shows the desktop, and for a couple of seconds the screen turns black and my PC reboots. After it reboots, no display comes out and i am pretty sure its because of the PSU. This happened when a sudden blackout occured then by the time I turned my pc on, this happened. Not just because of the blackout, but i did already experienced this before the blackout. I can prove that my psu have "sometimes" no juice to power up my system when I remove the RAM stick and count the seconds of delay of the beep. Sometimes my psu will work fine but sometimes this problem happens again. Need help?
