Hi,
I hope you learned people can help me out here. These are the problems that have been cropping up recently.
1. Upon turning on from cold, my PC will start, post (sometimes) then turn itself off and immediately back on again, this sometimes happens 2 or 3 times then it boots up.
Therefore I thought it was the power supply, however the other issue which may or not be related.
2. Whilst playing a game or just right clicking a rar file to extract, or anytime really. The signal to my monitor goes, and i get a black screen, also my phone which I charge at my PC stops charging. However the power to the PC stays on and I can hear the game still playing in the background. So it is as if the signal to the monitor is turned off as is the USB. Although I have not seen my external USB HD turn off!
Any ideas? As I said I thought it was a power supply issue but not al the power goes, also I do not think it is Windows as it happens on boot.
I should also point out I have made no hardware changes, nothing has been overclocked etc. Nothing has been changed for months.
Thanks for any advice.

Well, I would make sure first that its not the PSU, is it possible to swap it for a week?
If not:
Carefully fiddle with the PSU cords during your computer is running, carefully "twist" "touch" them, move them around etc. I think You get the idea.
Also run a very demanding game with vsync/fps limiter off.
if the problem occurs during these 2 scenarios it is very possible that its the PSU.

could be easily the psu, but i would go for a broken board. open the case and check for damaged capacitors

A bit of an update.
I stupidly did not realise that the only USB devices to lose power were those plugged into the monitor
I ran Furmark continuously for about 20 mins, no issues
I loaded up WOW and it did it twice in about 5 minutes.
Leaving the PC on idle does not seem to cause the issue.
So it seems as if for some reason something is knocking the power or signal off to the monitor, as I said the game can be heard running in the background so I don't think it is the GPU or the PSU. I am going to swap the DP cable once I can get hold of a new one. What confuses me is why it does it now and again then is fine for hours. I had a marathon gaming session yesterday and it did not do it once.
I have also thoroughly checked the Windows power options, no changes have been made to those, and anyway the monitor did not turn itself off whilst I was out this morning for 2 hours.
Any further suggestions would be welcome, obviously it could just be my monitor is dying?

uff, try another display (or try that monitor with another pc). maybe its occuring randomly hence it happened with wow and not furmark?
still can be the psu,board or even gpu. without testing stuff you cant find the problem
