Monitor driving me nuts

[Malfeasant]

Graphics card signal is carrying spikes to the monitor. Get external card. Or power to monitor is dodgy. But I would guess signal. Is your pc on ups. If it is, then either dodgy mobo or get graphics card. Switch out monitor now as well

If this was the case, then wouldn't the monitor have worked fine when I plugged it into the 2nd PC? Yet it had the same problem. Will try to get another graphics card tomorrow regardless, just for surety sake. Though, this begs the question why it was working fine for the last week. I really can't recall doing anything different from what I usually do. In fact, if anything, I was less on the computer than normal.

Did you use a new DVI cable? I still think that the sync issue could be at play, if the same cable was used...

Yes. Currently using the one which came with monitor.

When I say signal, I mean the electrical current that is being passed over the signal cable is causing the problem. You may find there is a short on the mobo or graphics outlet, which could be pushing over-voltage down the cable. The monitor will then be receiving voltage spikes beyond what it is designed to handle. This will be why lower resolutions and frequencies are OK, because they are less susceptible to voltage variances. The problem is that you are damaging the electronics on the monitor which is processing the signal. This will be why the new monitor has been fine. After a week of taking a beating, some of the components could be giving up already.

First port of call, get a graphics card and whilst you are there switch the monitor out under warranty. Just tell them it keeps blacking out. Don't give details. Another option is the 5v and 12v supply to your mobo could be problematic. Switch the PSU. But do the card first. If the problem still exists, then try the PSU.

But I assume at some point you have installed a Linux distro and set up the same resolution. I highly doubt it is software though.

Ah ok I think I understand now. Thanks for explaining that to me. Will definitely try to get my hands on that graphics card today to test.

Good advice, I think the PSU should definitely be looked at.
