  1. Are you overclocking the cpu? What is the 12v rail in amps for the power supply? 400w is marginal for your system.
  2. no i am not overcloking my cpu..!!!


    the detail wriiten on my smps is::


    AC Input
    220VAC 4A 50Hz

    DC output
    +5V 40A -5V: 0.5A
    +12V 20A -12V: 0.5A
    +3.3V 28A +5VSB: 2A
  3. is it ok??

  5. I think the problem may have been because of the psu but I can't be sure.The 5770 requires 450w power supply but you have only 400w.Try out this psu.It should solve your problem

    For a single Radeon HD 5770 graphics card system the power supply should have a +12 Volt continuous current rating of 22 Amps or greater.

    Your power supply's +12 Volt current rating is 20 Amps which is too low to properly power the system with that graphics card.

    If you can find a Corsair Builder Series CMPSU-430CXV2 it will also provide sufficient power.

    It is not the power supply's wattage specification that you should be focusing on. The most critical specification is the power supply's +12 Volt continuous current rating followed by DC Output quality (i.e. good voltage regulation, low electrical noise and ripple) and then the required number of PCI Express supplementary power connectors.
