I have a gateway computer that is less than a year old. its a Vista operating system. every few days it will just suddenly shut down, telling me there's no video signal. usually its accompanied with 3 loud beeps. after that, i can't get it to come on and stay on for several days unless i turn it off and leave it alone for a day or two. then it will work fine again for a while. my computer just went out of warranty and gateway has been no help. they just keep telling me to unplug it, push the power button for 15sec and then plug it back in. this works maybe once, but then it stops working.EDIT: Moved to Internal Hardware...MG
