Bad GPU or bad LCD

[Konstantine]

Hello. When I try to watch a video on youtube, be it full screen or not, or when I log to Windows Live Messenger, or just showing my desktop, I get some "objects" (I really don't know how to call them) all over my monitor. I checked the cable connection(VGA) and it's ok. I don't know if it's the cable's fault or not, but I will try when I find another.

My GPU is a radeon x600. Upgrading is not an option.

Do you have a 2nd video connection on the card? If so, try that. I had a problem with a radeon x1650 PRO from display 1 with red random lines that didn't come out of display 2.

If you mean digital(the white cable) I got one, but I cannot find it right now. Will try when I find it.

If it's displaying in the screenshot it's definitely not the LCD. What that screenshot shows is artifacts from the graphics card. It could either be bad graphic memory or a bad driver.

Those artifacts look like the signs of a bad card to me. And if it's indeed the card, and drivers change nothing, then upgrading will have to become an option. Whether you like it or not.

Deffo a bad card, nothing to do with drivers. make sure its seated correctly and has enough juice to power it, the only other times I have seen this happen and it wasn't power or installation it was due to over heating :(

If your capable enough, try a linux live cd of some kind such as ubuntu. That way you can rule out the current operating system/drivers/else. If it still occurs while using the live cd then its without a doubt the hardware videocard. Just boot off the disc and try the built in browser on youtube.

Rule of thumb;

Artifacts on screen that don't appear in screenshots - Monitor is dying.

Artifacts that appear on screenshots and monitor - GPU is dying.

Sadly, your GPU is on the way out and it will need replacing before long. Drivers don't cause this.

Thanks guys for the replies. :) Will try live cd. If it still occurs, I will have to replace the GPU. Again, thanks a lot!

Check the card and make sure it's clean as well. An overheating GPU can cause artifacts similar to this as well. It probably is a dying card, but it's worth a check.

Yeah at least with a Live CD you can verify its hardware related, then move on to checking its seating and making sure the fans or temps are clear and in range. If all else shows true then its just a failing gpu/card. In this scenerio replacing a bad gpu on a desktop isn't that difficult.

Make sure the fan is spinning on the card to keep it cool and there is enough ventilation in the case. Another way we could help is if you could possibly down clock the card and if you use any extra power cables to make the card work, try changing them. If all else fails, try changing drivers but I suspect that the card is dying and upgrading will be unfortunately the case.

The X600 is 6 years old so it's had a good life. :)

if you can take a print screen of it, then it's nothing to do with the monitor, it's the graphics card.

i have had a similar issue with software installed on my computer, mainly AVG free, which caused things to stick on screen, uninstalling it (for a totally different reason) sorted it out. try uninstalling your antivirus and see if it fix's the issue.

As others have said its eaither a bad graphics card or a resent install of a program could be the cause

Graphical artifacts are 99% bad hardware, usually memory or the GPU is over heating.
