hi, im new here & not sure if im in the right place but here goes....
i've had this pc setup for 3 years working perfectly, about a month ago i removed the video card (sapphire hd4870 512mb) to use in another computer. so i didnt power up this pc for a month & just yesterday i tried turning it on using the onboard video card and the asus splash screen was all distorted and frozen. i turned it off and unpluged all unnecessary hardware then powered up again and got a black screen (monitor light flashing-no video). i then tried putting the hd4870 back in the computer thinking maybe its a problem with the onboard graphics card but no change( black screen) & 3 lights on the video card started flashing which ive never seen before. i also tried 2 different power supplies. ive noticed in a lot of cases its just a matter of an adapter or plug not properly seated, i tried my best to make sure everything was connected properly. so in the end i just have the power supply connected to the mother board with 2gb ram & using the onboard video, i tried with & without bothe the harddrive and dvdrom... no change.
specs...
processor: AMD Phenom II x2 - 3.1ghz
motherboard: Asus M3A78-CM
memory: kingston 2gb DDR2
power supply: Corsair vx 450w
dvdrom: LG
harddrive: western digital 320gb
i posted in the motherboard section because it feels like thats the problem but i really hope not.
if theres something obvious im not seeing i'd appreciate any suggestions, thanks a bunch.
