When I start up the computer the screen goes black at windows(vista home premium) startup and states "no signal". If I put the computer into sleep mode, then wake it up, the screen works. This also tends to happen when I playing certain video games, such as Free Realms, but not other games such as Oblivion and Civ 4. I had it diagnosed at a computer store and they said that no problem was found in my hardware and that "there were signs of Windows O.S. corruption" and recommended a system restore.
I restored my computer to factory settings yet that hasn't helped. I also cleaned the inside of dust and put new thermal paste on the heatsink.
My computer is a gateway with an AMD Phenom 9600 Quad-Core processor, 4 GB DDR2 memory, and an ATI Radeon 3650 HD graphics card. The monitor is only a few weeks old and works perfectly on other computers.
Any help or suggestions would be appreciated.
