I recently replaced the fan on the northbridge chip on my motherboard with a heatsink, as the fan was bust and very loud! To do this, I had to basically dismantle my PC and remove my motherboard. I did this very carefully, to ensure everything was safe, and went back in the correct place.
I connected everything back up, booted up, and it started and was completely fine. However, my mouse and keyboard seem to dis-engage them selves at random intervals, and I have to re-boot to get them back and working.
It seems to happen when I leave the computer for 10/15 mins or so, although this could purely be coincidence. They are fine when I boot up, and I do not jog or move the tower at all.
Any possible help/ideas/thoughts on this would be very much appreciated.
Thanks so much for your time
