Recently a problem has arose with my main PC. About a week ago, the screen just turned off and back on again, repeatedly, and never stopped. I had been using my PC, went downstairs for a while, and came back to the screen flashing on for 0.1 seconds then the power light on the monitor went off, came back on ... screen flashed back up ... then off again and repeat. After a hard restart, the same thing happened. I turned off the PC, tightened the DVI connectors on my monitor and the graphics card, and turned it back on and it happened again. So I took the PC apart, cleaned everything, re-seated the GPU and RAM etc and that seemed to fix it.
Until today. It is happening now randomly all the time. Anyone know what this could mean? I read somewhere to check my cable (DVI to DVI) but I don't have a spare to try. I'll try to get an HDMI lead tomorrow to see if that solves this problem. It is clearly not software.
I am thinking along the lines of :
1) MY PSU is blown (it's a 6 year old XFX 550W Pro Edition)
2) My monitor is blown (it's a 4 year old LG 24" IPS 1080p)
3) My DVI cable is blown (probably NOT though right?)
4) My monitor power brick is blown (don't have a spare to test either)
5) Something ELSE is blown.
I have spare GPU's so I can test that. I have spare monitors so I can test that too. But guys - what would think it was off the top of your head / in your experience? I have never seen this before.
