Find two fields: "core Frequency" and "dram Frequency". Reduce the rates of both frequencies. First, change the values to 50 MHz. Press the "Test" button, and complete the analysis of the stability of a video card. If at the time of inspection errors, reduce the frequency by 50 MHz. Follow this procedure until, until the device starts to work stably.
Remember that this process will lead to slow performance. It is natural to use the faulty device is extremely dangerous, so it is better to sacrifice performance. Select the check box next to the option "Load settings with Windows" and click "Save". Then restart the computer.

Advice 2 : How to know whether the burned out video card
Video cards are devices that are used to display graphic images. They can be expansion cards or integrated into the motherboard. Expansion card inserted into the slot on the motherboard, the integrated runs in a separate chip or as part of the North bridge. These details of the life of graphics cards you will need to know how to act if you turn the computer on the monitor does not appear at all, or it is distorted.
After turning on the computer in the normal mode, if the speaker connected to the motherboard, you hear one short beep. In case of malfunction of any equipment the signal changes. There are special tables of signals BIOS that can help you determine the problem right at the start of the computer. Most of the motherboard manufacturers to indicate a malfunction of the video card appointed one long and two short beeps. So when you switch on the system unit you hear one long and two short "beeps" and on the screen appears the message "No video signal" or no image, the problem is with the video card.
Unplug the system unit from the mains. If your graphics card is made in the form of an expansion Board, Unscrew the tightening screws which it is attached to the body. Pull down the plastic clips securing the card in the slot, and then remove it. Take a normal eraser and wipe the contacts, the problem may be that they are oxidized. Piece of thick paper (not newspaper) roll into a tight corner and wipe the contacts inside the slot.
Insert the graphics card back firmly until it clicks and turn on the computer. If nothing has changed, in the same manner, check the map on a known good computer. If the other computer the image appears, then the problem is in the slot on your motherboard.
Video card failure can manifest itself differently: for example, appear on the screen stripes and dots (called artifacts), colors are incorrect. Remove the card from the slot and carefully inspect it on both sides. The map should not be swollen and leaking capacitors, burnt areas and mechanical damage. If visible defects are not, perhaps, the cause of the problem – the overheating of the card. Perhaps inside your system unit, there is little ventilation. Check the video card on another computer.
When you hear one short beep, and the display on the monitor there may be from the external connector's disconnected or faulty interesny cable.
