Hi, I'm new to this forum but I am an experienced computer user. I have a S5000 series slimline desktop (model S5615uk to be precise) and recently it has started to randomly drop video to the external monitor. This can happen afeter 2 hours, 30mins, 10mins completely random and does not seem to be related to what I am actually doing at the time. So, the monitor goes black and only way to get back working is to do a hard power switch re-boot. I am rumnning Win 7 premium edition, have cleaned out the fans/ interior, reseated memory, cables, checked for virus, malware etc etc to no avail. On occasion, the screen displays ramdom characters instead of black but still need hard reset to get it working again. This is the standard onboard video I am referring to as I have not installed a separate video card. Suspect it is more likely to be hardware related than software but would appreciate any suggestions you may have.
Thank you.
