  1. If you suspect a power problem why no info on the PSU? Its either that or the GPU is faulty.

    What do you mean by UPS? Do you have a battery back up system or did you mean the PSU?
  2. ups uninterrupted power supply for backup
    i have 450 watt psu but its not 450 actually its a old version
    and i'm using win 7 32 bit
  3. here is my mb or cpu temprature

    my room temprature is 42 c
  4. Ouch, high room temp. I'm assuming thats your bios? So you have a 51c temp at idle? The other issue is your 12V rail is a bit low at idle as well. I could certainly see if you try playing a game that the temps go up to much, causing stress on the PSU, and it causes the 12V rail to go out of spec. (11.4V is the spec, you don't wany anything lower then that.) I suggest finding a way to bring the temps down. I'd start there. You might want to see about monitoring your 12V rail while gaming as well.

    Well, it helped some. You dropped a few degrees and gained .05v on the 12V rail. Its just not enough. I new PSU will help. Getting it cooler in there will help out as well.

    I'm not that familiar with CM PSUs. They make good and bad ones. Either look up that model online or wait for someone to tell you.
  10. thank you new psu helped me
