Hello guys i seem to have a problem that has only recently (about 2 weeks) started. It does seem to be pritty random anything between 5 to 20 minutes the screen will just go black, as if the screen saver has just come on for being idle (while i am using the computer, makes no sense to me)

I have checked my power options (windows 7) and my screen saver has been turned off, hibernation off too so, i have no idea what is causing it to do this, nothing set on my monitor either to make it go off.

No discrete GPU? You're using the onboard then?

... You're using an OcUK Swift PSU? Well... I think I can see the problem.

Well I bet you it's probably the PSU finally struggling to power the 5770. You should avoid the OcUK PSU range if you're building a gaming PC, they give very poor amps on the 12v rail and aren't made from reliable quality parts. I would usggest replacing it with something like this if you want to stay cheap: http://www.overclockers.co.uk/showproduct.php?prodid=CA-063-OC

i originally had this Corsair CX 400W ATX Power Supply (CMPSU-400CXUK)

but the fan went on it, so just bought a cheap one as i was planning on building a new PC
 
Well, even for a cheap PSU, the Swift range doesn't have the power to power a 5770. Even the CX 400 is a better PSU. When did you replace the PSU?

over a year ago, plays all my games perfectly fine(BF3, ME2+3, Fifa 12 ect ect), as i said its like the monitor will go into sleep mode, really strange.
 
I would still replace it anyway, I wouldn't trust that PSU in my system at all. Could be the PSU finally on the verge of giving up.

I suppose you could try updating the graphic drivers to see if that helps.

The problem seems to have happened when i updated them. When i build my new computer i will put a better PSU in there.
 
just realised there is an update for my card, will try this and hope it fixes my problem.

Thanks for all your help guys.
