I have a old desktop computer manufactured about 11 years ago, and it came with a nVidia GeForce 256 graphics card installed. (Not built-in; it came as a PCI card pre-installed)
Now, for the past few years this card has worked perfectly fine. Until recently.
Recently, my screen has abruptly started adding weird-colored lines across the screen, then promptly freezing my entire computer - keyboard, mouse, screen, all not working - and I have to power off/reboot using the power button.
I ended up changing out the card with a ever older one that can't display anything higher than 800x600x16 resolution - which quickly got on my nerves.
I've since put the nVidia card back in, and so far it's working fine - except for two times it's distorted the screen's color, then returned to normal.
This has only happened about a year after I got linux, but I have no way of checking the card with a windows computer (the hard drive on my PC is too small).
What could be causing this? I've checked the fan on the card, it's a bit dusty (after blowing compressed air at it) but it moves freely. Is there any way to fix this before it completely goes out (and I have to deal with 800x600x16 for the rest of this computer's life)?
Thanks in advance!
