Question about Graphics Cards

1 Answer


My PC display is experiencing problems like corrupt images, faulty animations, sometimes I can see vertical lines on the screen. On the worst case, my PC frequently stops responding and more often the screen display starts blinking or blacking out. I tried reinstalling the display driver a few times already. I already got the latest version of the driver. I put the display configuration & the hardware acceleration bar to the lowest setting & still the problems persists. Only on the windows safe mode and when I disabled the video card on the device manager properties the problems stop occuring. I think it could be the Nvidia GeForce2 MX400/400 graphics card that has problem. On the other hand, my power supply already has problems. Can this be the cause of the glitches in my display? What should I do?

It is highly likely the graphics card is faulty and or the RAM on the graphics card is faulty.
Try reseating the graphics card first, if this does not fix the problem, beg, borrow a different graphics card and swap it with your Sigma video card. If it is OK then the Sigma is faulty and needs to be replaced.

It displays colorful lines on the monitor...cant see nothing

Test your laptop with an external monitor and find out if the external video goes bad too. If both, internal and external images go bad, you have a problem with the video card.
If external works fine and only internal goes bad, most likely it’s either bad video cable or LCD screen failure.

This may not be much of a solution but it seems odd that a video card would have some white lines gong across the screen. I would say its a driver error or the monitor is busted. Only way to tell is if another monitor is used on the system.

If it is a AGP card it is not possible that the graphics card can make the keyboard and mouse not respond.
If it is a PCI card there is a chance that it can do what you mentioned.
Also it could be the size of the graphics card, a 512 mg card can sometimes need a 500W power supply so you could get your power supply diagnosed as well.
Hope this helps

I have the same card....and my PC stops responding from mouse movements sometimes, but not anymore. I found that if I always use the HIBERNATE feature of Windows, that my video problems vanish, so I think the problem is related to video RAM, but not sure, because virtual memory caching plays a large role during wake from hibernate. Also ensure that BIOS video settings are not too extreme, go with the normal or default video settings.

Its most likely the video cards fault,
however a bad PSU can cause these problems.

No Power To The Computer
Here you must first check the wall outlet for power by connecting another device such as a radio or lamp to be sure power is present. If the computer is connected through a surge protector, check it as well.
If the wall out has power, check the power cable going to the PC to see if AC voltage is making its way to the system unit. Do this with the use of a multimeter.
If there is power, you will have to open the PC and check for power from the power supply to the motherboard.
When using a multimeter to check voltage, be sure you have a good ground for the black lead of the multimeter.
Rebooting Problems
One main problem you may face with an ailing power supply is that it may reboot the computer without any warning. All information is lost and it seems as though this happens at the worst possible time.
Booting errors when the computer first starts up may be another indicator of this component going on the blink.
Power Distribution Problems
When the power supply begins to fail, you may receive power at one device and not another. For example, the hard drive may receive power, but the CD-ROM drive has nothing at all.
Another headache that would cause rebooting is the intermittent power going to the drives or the motherboard itself. Follow the steps below to check your power supply should you experience some of the above problems.
