i recently bought a computer (around the end of Jan 2010), and ever since about 2-3 weeks after i bought it, i have been randomly losing signal with the monitor. This happens when the computer goes on standby, sometimes when i try to turn the computer on, and sometimes after i have used the computer for a few hours. I installed dual-screen monitors soon after i bought the computer. Recently i reformatted the computer, and this seemed to fix the problem for around 2 weeks, but now it is starting up again (i went to a computer shop and they said that there didnt seem to be any problems with the hardware). specs are: * GIGABYTE HD 5750 * ASUS P6T Motherboard * Cooler Master 600W PSU * Windows 7 Pro * 1TB Hard drive * 4-6 GB of RAM (cant remember exactly, havent been able to check) My two monitors are a BENQ 22' HD LCD, and a 19' DELL LCD (which i bought around 2005). Both monitors lose signal.
