Graphic card turns off, monitor shuts down

simcat
Hello,

I have a strange problem and I do not know what to begin with.
I have Asus P5K mb and Asus GTX260 graphic card. PSU is 400W. WinXP.
For about 3 months everything had been working perfectly. Several weeks ago the monitor started to lose video signal and go to sleep mode (and did not wake up). The thing is this can happen any time, not only in power consuming games - during movie, reading, surfing. At first, rebooting helped. Then it got worse - I could not even pass through Windows loading screen. When monitor shuts down, the sounds are as if the loading stops. And yes, when I am watching movie - after monitor loses signal movie sound also stops in two seconds.
Sometimes when I reboot monitor is off from the beginning, and beeps tell me that there is no VGA card. I cleaned the connectors, but that did not help.
I searched some technical forums, and saw advice to update the drivers. During the update process in Windows the problem repeated, video signal was lost. I successfully rebooted and tried again, and at the same place of drivers update that happened again.
I rebooted in safe mode, deleted old driver of the card, and installed the most recent.
For a couple of days it worked ok.
I even rebooted several times in a row to test, no failures.
But then the problem returned. Now sometimes there is no video signal at all, sometimes Windows loading completes successfully, but in several minutes lost video signal again.
Onboard temperature of VGA even in 3d does not exceed 60C.
It might be PSU problem (not enough power), but again, it worked properly for several months.
Sorry for the long text, but I am really confused with this.

    Power supplies can sometimes gradually fail and then reach a point where they breakdown supplying power due to overheating. As teh heat increases in the power supply, the impedence rises (think resistance) and generates more heat, which breaks the unit down even faster. Typically this is an electrolytic capacitor that is the source of the problem, but unless you are an electrical engineer, you aren't going to find it.

    You may also need firmware updates for the system board and BIOS to run some of the newer cards.

    You could also have a video card that has been damaged because it didn't get enough power, which is an issue known as brown-out burn.

    Replace the power supply.

    Update the firmware.

    Update the drivers.

    If the issue doesn't go away, bad video card.

    Thats right the card you are trying to use is a power hungry monster.
    Time for a new PSU.

    You will need a 650 watt or higher to over come your issue.
    Your computer is shutting down because it does not have enough power to support it. So get hold of another power supply, get hold of a 700 watt, or over, and you will be fine. :)

    or the power supply is failing/going bad. Whatever the reason id suggest getting a NEW 500-550 watt PSU.

    Yesterday I finally got to the shop and purchased a new PSU - now I have 700W Thermaltake.
    It seems to work ok, so I think the problem's solved.
    Thanks a lot for your advice!
