Burning smell and display issues

Hi all, hopefully you can help me! :)

I have a GTX 650, slightly overclocked, stable on OC settings and I have never had any issues before, along with a Samsung SyncMaster 2443BW monitor - again, no issues for years.

That all being said, I started to have issues with my screen going black, after noticing an electrical burning smell a few days ago. I shut everything down there and then, however, after checking everything, I could not locate the source of the smell.

My GPU smells fine and I have done a hoover of my computer, including GPU socket since. I have also tried disabling my drivers for my GTX 650 and I have also put it back to the original, standard clock/memory/voltage settings to no avail.

I have tried plugging my DVI to DVI lead from my display directly to my motherboard (without doing anything computer wise) instead of my GPU and this doesn't seem to do anything.

I have downloaded Teamviewer and my computer is fully functional when the screen issue occurs.

I also get the following on Windows 10 start up now: 0xc00000f (boot config) - although you can bypass this by ESC and everything seems to work fine (windows wise, not the display!!). I am not sure if this was caused by my multiple inpatient restarts to get the screen to work! Windows is on it's own SDD.

The display issue is really intermittent. It sometimes works on start, sometimes it doesn't, then sometimes I can use it for 15-20 minutes after logging in... only to encounter a random period of blackness. I must stress that it's not a simple flicker - it's more like 10 minutes + of no display.

The monitor blue light remains constant (meaning it has a source), however, nothing shows.

I did do a reboot in safe mode, same issue with the black screen, however, I did notice on a couple of occasions, the screen was on, but there was no backlight, but it's a mix of no backlight or complete black screen.

I hope the above all makes sense, sorry for the lengthy post - I would be grateful for some help!

Cheers

Alex
