Last night, I left my computer on while I slept; the sleep function has not worked for some time (it tends to kick itself awake randomly). This has not presented a problem so far, but this morning I awoke to find that my monitor had not only failed to automatically blank into power-saving mode, but also displayed some issues that made it unusable.
Specifically, there was massive vertical flickering - the top of the screen stayed more-or-less where it's supposed to, but the bottom of the screen kept flickering between different points varying from where it's meant for to an inch or more below the bottom of the monitor, dragging the middle of the screen with it. Horizontal lines would appear as it did so. There was also a little bit of discolouration; the colours seemed dimmer
So I jumped online and started researching. Before I found an appropriate answer, the issue ceased. The monitor is currently functioning fine, and has been for the last hour. Nonetheless, this issue concerns me. If this monitor breaks again, I cannot currently afford to replace it.
I've run a program from the manufacturer to install drivers for all their monitors. I've also updated my GPU drivers. I ran the Windows 7 Troubleshooter before either of these steps, and found no issues. I also switched my monitor plugin to the other DVI port on my card.
Specifications:
Windows 7 64-bit
4gb RAM
Nvidia GeForce GTX 560
i5-3570 CPU
Just as I finish posting this, the issue has returned. The vertical flicker and horizontal lines are less intense, but now the colour issues seem more pronounced. This flashback lasted less than thirty seconds.
So what's causing this? Is it my monitor, ribbon, GPU, or some other part of my system that needs replacing? Maybe it just needs a good cleaning?
Additional issues, maybe related, maybe not:
Windows Update has been non-functional for maybe half a year, unknown reason.
Computer likes to kick itself out of sleep mode without input.
I get an error 1935 message whenever trying to install Visual C++ 2005 Redistributable, which comes with several games, and am unable to play these games because of it.
That's all I can think of. Here's hoping!
