Question about Computers & Internet

FAULTY DISPLAY 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'm using a Nvidia Geforce2 MX400/400 video card which I had for almost 2 years now. What should I do?

No image, Just red and blue vertical line on display.

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.

Vertical scan lines

It sounds that there is a loose contact to some connection wires, the flat wires that comes in, and go out the T'Con board. Re-seat all the flat cables and check. Check this link too. It has screen shots to different faulty displays. Pull up older posts and compare with these images to your TVs screen, and make confirm. Remember, vertical lines can be due to a faulty LCD display screen too.

Pink vertical line

To start try reinstalling display adapter drivers. Try also to start from a boot disk or to install a different operative system.

If it does not go, and does not depend on the system, a static vertical lines is either faulty display adapter or faulty LCD display. Usually the video adapter.

I was playing online games on my sony vaio. Suddenly I got blue lines on the screen and the laptop stopped responding. So I tried restarting the laptop but I get blue thin vertical lines before the laptop...

Blue thin lines before it boots will rule out an operating system or driver fault. So it would appear something in the machine has failed.
Do you have a VGA monitor you can connect to it and see whether it shows the fault? This will show that if the fault also shows on the external monitor, it is likely an electronic fault on the main board, whereas if it works on the external monitor but not on the built-in monitor, my guess would be the cable that goes from the main board up through the hinge of the screen into it, or a connector, or an actual fault with the LCD display.
Windows booting normally once the display drivers were disabled indicates to me that Windows is no longer detecting the faulty display and therefore boots normally - possibly pointing to failed electronics in some way. It could even be corrupt BIOS that controls the video or something along these lines, though that's unlikely.
Good luck, either way it sounds like it's off to a computer repair shop. Is it under warranty?

Try replacing your video card. That video card may not work with your motherboard.

The only thing u can do is to change ur graphic card

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.
