Hey,

A couple of nights ago, I overclocked my i5 4690k to 4.2ghz at 1.175v, and it seemed to run great in games, rendering, etc. Last night I decided to run a Prime95 blend test overnight, and I left it running - in the morning I got up, and it was fine, stopped the process and saw the max temps were 82 degrees, 70ish on the motherboard, I then shut my PC down and got to work. Just as I went to boot it now, I'm not getting anything on my screens.

I reset the CMOS, and then managed to get it to boot to my integrated graphics on my TV, then tested each stick of RAM individually, and it all booted. Then I put the graphics card back in, all the RAM back in and it didn't display anything again. Even with the GPU in but using integrated graphics, it's still not displaying anything.

Any help is much appreciated, the issue seems almost intermittent - I'm wondering if my GPU has kicked the bucket out of coincidence.

Thanks
Sam

Okay so update with a different PSU: Still the same issue, only boots when the quantity of RAM changes, so if I either take a stick out and boot it, or put that stick back in to boot it. Quite the expensive jumper 😂
