Random Signal loss.

Hey everyone, Randomly my Monitor will go completely black and display a message saying "No Signal", This has happened once on boot up, twice whilst watching youtube videos and once when browsing the web.

I haven't got a clue as to what is causing this, I've checked temps:


GPU Core 25C
VRM's 25C
CPU 30 - 35C


GPU Core 34C
VRM's 60-70C
CPU 48 - 55C

I've also checked the monitor cable which seems to be fine, Used my xbox 360 with my Monitor and it worked fine ( No signal loss )
Voltages seem to be normal, here's the system

Core i7 920 @ 4Ghz 1.296V (WaterCooled)
3 x 1GB OCZ 1333Mhz 7-7-7-21 @ 1200Mhz 6-6-6-18 1.64V
Gigabyte HD5850 Reference @ 1000Mhz Core 1200Mhz Mem 1.225V (WaterCooled)
Gigabyte GA-EX58-UD5
Corsair HX850
Corsair Obsidian 800D
ASUS Xonar D2 7.1
Lamptron FC6
Sammy Spinpoint F3 500GB
7 x Fans. 2 x Cold Cathodes
10W Pump
Custom WaterCooling
Acer GD245HQ

Seems to me that the Monitor is fine as I don't get the problem whilst using my xbox360. The Graphics card seems Fine aswell, I played 3 hours of Fallout new Vegas maxed out with no problem at all.

Some kind of PSU problem perhaps?

Any suggestions are much appreciated.
