recently bought a new pc, my specs are
AMD Athlon X2 5200+ 2gb ram 250gb hdd nvidia 8500GT ASUS M2N-e SLI 550w EZcool PSU running windows xp pro service pack 2 this came with a 550w psu installed. it only came with 1 fan (for the cpu) and it was running quite hot, around 55 degrees c. so i bought 2 80mm fans to provide some extra cooling, i mouted them, and plugged them in the 3 pin connectors on the motherboard.. started it up and they worked fine. my system was arouind 15 degrees c cooler. the computer was fine all day. running normally. the next day i went to start it up again. and it began starting up and just after the bios beep it suddenly turned off. i tried to turn it back on but it did the same thing. i waited for 10 mins and turned on and it booted fine. loaded up windows and everything. i went opened firefox, and then suddenly it turns off again, not shutdown, just turning off. i turned it back on, and it was fine, firefox was working and everything seemed to be ok. i launched a game (hl2 garrys mod) and when to spawn a prop, and it turned off again. after all this i decided to remove the fans i added and sure enough, system boots fine and operates normally without random "turn-offs-" i know it is not a virus because this only happens when the fans are plugged in. also my system is cleanof viruses and maleware. basically i think my psu is shutting down due to too low voltage. am i right and would a new psu fix this? my voltage readings (without extra fans) are Voltage CPU 1.36v DIMM 3.33v +5v voltage 5.07v +12v voltage 11.33v i have don't really know much about psu's so please help me! Thankyou |

I've commented before on these EZ cool psu's, and just how terrible they are. They're very inefficient, less than stable and run hot regardless of build.
I completely agree that the psu is your problem. Frankly, you answered your own query with the removal of the two fans. I'd swap it out and look for a Coolermaster 500w, Antec 500w or Enermax Liberty 500w. The Enermax would be my choice.
