Lately my 22" has been flicking on and off every flew mintutes while gaming. Go out of the game and it stops. I tried switching monitor ports on the video card etc,, made no difference.
This morning i couldn't get the video card to recognize the 22 aswell as the 17" it would only do one or the other, but on the load up screen it would appear on both monitors.

So, atm i only have the 22" connected up.

I know its not a driver problem, so im thinking since my psu is a cheap chinese pos that it might be starting to die and isn't feeding the video card with enough juice to power both monitors.

that sounds right to me.  wierd things hapen when your not getting enough power.

I had a similar problem with an older case--I had too many fans and accessories tied to an under-powered PSU.  Intermittent power on/off for the first few days told me I'd bought about 100MW too small a PSU.  Most PSUs have internal protections the trip if you're drawing too much current (i.e. overloaded).  That's what happened to me. 

So, from your symptoms, it might also be a failing Mobo PCI/PCI-E port or even the GFX card itself starting.  Depends on age of the components, and how often it's happened.  PSU upgrade/replacement is never a bad idea though.

Yeah I had that problem before I could never figure it out, I just replaced the monitor and the problem went away, I was told to switch the cabling and check the refresh rate. But I used that as an excuse to buy a nicer monitor, LOL. Try making a few adjustments and change the cables.

the thing is the monitors are fine. and the gpu supports both cards at once, just not when actually in windows explorer. its wierd

If the entire rig isn't shutting down, then it might not be the PSU.  Unless you're right on the ragged edge of how much power is needed vs. how much you're actually supplying.  Sounds awfully like a monitor problem, especially if its intermittent--Ant's not far off that it may be the cables.  Are the cords bent badly? Might be shorting out, hence the flicker. .... maybe it is the refresh rate?
