HIS Radeon HD 6770 Black screen

I received my new >HIS Radeon Hd 6770< from newegg this morning. So right away i took out my old Card
(Radeon HD 3650 512MB) and plopped in the new one. My Motherboard only had one pci-e x16 slot so i put it in that one. The card came with a 2x 4-pin to 1 6-pin adapter(?) so i took two 4-pin connectors from my >PSU<, plugged into the 4-pin slots, then plugged the 6-pin into the card. After that I took the DVI to VGA connector that came with the card and plugged my monitor into it.
Now I turned on my PC, the cpu fan revved up, the card's fan revved up, but the monitor was blank... Nothing showed up at all and I could not even go into the BIOS.
I was wondering if anyone could tell me what the problem is.
I uninstalled my drivers and disabled my old card beforehand btw.
HELP!


please? :??:

    Well, it's quite low... I think around $25-$35
  10. well you better stay with the old card for now a good psu cost the double of this by the way give the name and model for your motherboard some older card could not handle new graphic card

    But I read somewhere that v 2.1 cards can work on v 1 slots?
    and i think my current card is pci-e 2.0
    EDIT
    wow sorry... I should have read that wiki article you posted: "2.1 breaks backwards compatibility" :sweat:
    oh well... so I need a new Motherboard AND PSU?
  14. befor you buy something what are the specs of the other parts and complete mobo is not a dell or hp or any similar maker

    Well i think i might just get a refund for the 6770 and buy a gts 450 because it is almost the same performance and takes less power and is pci-e 2.0
    Btw my cpu: pentium d 945@ 3.4 ghz
    Ram:4 gb ( 2 sticks 2gb ddr2 533 MHz)
    HDD: samsung hd400LJ 400gb sata 7200 rpm(not sure)
  16. Best answer
    i would suggest to to take that refund money from the 6770 and get a new psu and wait when you will have more available to go for a graphic card then upgrade motherboard cpu an memory,because even with the 459 gtx you will be limited by the cpu speed and memory to gain any perf with those parts
