acer aspire m7720
intel(r) core(tm) i7 cpu 920 @ 2.67 ghz 2.67 ghz
9 gb ddr3 ram
64 but operation system windows vista
old graphic card is nvidia ge force gt 220
old power supply was 450 watt
got a new 750 antec earthwattts
and a new radeon xfx hd 5870
i had no problems with installing the power supply and everything is hooked up to the right place but when i install this new graphic card all sorts of problems started ... at first i uninstalled all nvidia drivers then turned off the computer removed the card and placed the new 5870 and hooked up the 2 pci e connectors from the power supply to the video card and when i turn on the computer everything is fine i install the drivers from the cd giving with the card and when i comme to play any games the screen flickers allot and after a while turns in a green and white line across the screen ( the color depends on the game ) now i installed the lattest drivers ( i think ) and when i restart the computer i get no signal from my screen so no pitcures and i notice my mouse and keyboard was also not turning on and i didnt hear a beep noise ... soo i removed the graphic card and reinstalled the old gt 220 and everything works fine ... im thinking its a driver problem or a bios problem or something ... any help ?

I had the same problem. Try downclocking your card a little. Helped in my case.

Got to be a faulty card if it can't even POST (Power On Self Test). I'd get it replaced as soon as possible.

For example if you somehow put two 6-pin PCI-E cables into the card or left one off instead of using the required 6-pin and 8-pin the card would beep like crazy and not shut up until you switched it off, so it's got to be a dead/dying card I'm afraid.
