hey guys, i have a hp 1254 an i upgraded the psu an tried to install a friend of mine's video card (evga gtx 295) i know that its a older card but i know it works and would be a hell of a lot better than the integrated graphics. my problem is is when i put the card into the pcie slot and boot the computer i hear 6 beeps from the mother board. i have went into safe mode and disabled the drivers for the stock gpu before the installation of the "new" one. so when that happened i got my friends evga gtx 560 and tried the same process. no beeps but it will not show any video. how can i fix this problem?
