hi everybody ive got a proplem with my pc i think it might be a power problem but im not sure. when i turn on my pc all the fans turn on but the cpu fan its spin a bit than stops and spins and stops and the dvd drive makes a sound like when it trys to read a dvd and on the screen it says no signal. so i turn of the pc and turn of the psu from the back then wait a little and turn it back on after a small delay its starts and everything is bak to normal but i have to do this every time i start up my pc.
ive narrowed it done its not psu, not ram, not the optical, not the hdd, it could be either motherboard or GPU
4gb ram 800
1tb wd hdd
320gb wd hdd
new vantec 600w ion+2
It is quite possible that it is that PSU going through a slow death. I'd replace that Craptech PSU with something else now! Look for: Antec, PC P&C, OCZ, Corsair, Enermax, Zalman, BFG, or Silverstone/Seasonic (unless in a 220v area). The fact that you have to flip the power switch on the PSU means it's dying. Vantech is not known for any quality PSU's. A good quality 550W is more than enough for that system (with a little extra for upgrades).
Quite possible that the crappy coolermaster damaged the motherboard. However that Vantec is not doing any good anyway, they aren't even a 3rd rate company. Always go for top tier when it comes to power supplies.
