I built a computer recently and everything seems to work fine, but from time to time both monitors loose the signal and I can't turn them back on unless I reboot the computer manually.
It does not seam to be a heat problem and I don't know what else to do.
I don't know if this is a drivers problem, or if the GPU does not work properly.
Does anyone have a clue on how to solve this?
