I'm hoping for some advice on a video issue I've been having that I can't find any solution to. I do not know if the problem is software or hardware related, but please note that while I'm competent enough with most things software I am essentially ignorant about hardware technicalities.
Computer boots normally, monitor works normally up to the windows login screen.
I log into windows normally, but within 5-10 minutes (has been as soon as essentially instantly) the monitor starts snapping on and off into standby mode. It seems to happen in fits and starts, maybe 10-15 cycles of snapping on and off followed by random pause of 10+ seconds. Once it gets started doing this it will not stop until the computer is reset.
During pauses in the fits of on/off snapping what is displayed on the screen is all screwy - slowly/unevenly updated, ghosted windows, blank fields/windows etc.
I will reiterate that it shuts down to standby mode, not just "soft" flickering.
After determining with confidence that it was not a virus/malware (or at least not one within my competency to find and destroy) I pulled out my system recovery disc and reloaded the computer to factory settings. Once I did this I needed to reload the drivers for my aftermarket motherboard and my aftermarket video card manually. The mobo drivers went on smooth. BUT...
The instant I loaded up the driver for my video card the screen flicker issue reappeared.
I immediately deleted the driver and the problem went away again.
This driver is off the original in-box disc, so I don't think it can be corrupt. Without the driver installed (video card sidelined) there is NO problem.
I have checked all physical cables/connections etc and these seem fine. Is the video card itself dead/damaged? Or could it be something more insidious (super virus/malware that somehow survived the system recovery nuke?) And what diagnostics (physical or software) do you suggest?
Many thanks in advance!
