A few months ago the card was not working normally, causing blue screens on Windows and not letting the load. I took the card and cleaned it from dust. I also removed the heatsink and cleaned all the dust and the card was working again. A few days ago I had the same problem. I cleaned everything again but the problem wasn't fixed. The PC crashes on nvlddmkm driver. If I remove the nVidia drivers, the PC boots but I can only see a very low resolution with very low colors.
I intent to replace the card, but just wanted to ask if anyone knows anything about this problem.
The first time a few months ago, no I did not. I put it back as it was and worked immediately. I just removed the dust which was enough. But now, after I tried it a couple times with the old paste and didn't work, I removed the old paste completely very carefully and applied new paste.
The weird thing, is that the problem appeared when I tried to install and launch a new game. Since then, the problem disappeared once and I was able to use the card with my old games, but I tried again to launch that game and since the second time, it is not working. I tried several time installing and uninstalling the drivers, I even formatted my drive and tried with a new installation but nothing.
I would say that the card is dead (or dying). Always when removing coolers new paste is required otherwise you can not ensure that there is enough heat transfer from the GPU (same applies to CPU´s) to the cooler.
Probably it is dying.. But the first time when I removed the cooler and put it back without applying new paste, it worked for another 4-5 months without problems until now..
Why without drivers the card works with 640x480 resolution and 4 colors? Isn't that weird? Shouldn't be not working at all?
