4850 Gigabyte

I really do need your help.
I am currently on my sisterinlwas laptop (an old clunker) Can not get my PC to work now.
I installed a Gigabyte 4850 card into my PC and it booted to windows and then crashed then booted and crashed etc etc I checked all the connections nothing untoward ...I changed the connector the screen was pluged into (that turned the screen pink ) and it crashed just the same.
Not sure what is wrong or what to do...help
I dont have my system specs here sorry I know its a 650watt PSU and Gigabyte mobo
If I can find my first post I may be able to get the details but I need advice

  1. Did you make sure to completely remove your previous card's drivers? I.e., uninstalling your old graphic card's drivers, booting up into safe mode and use driver sweeper or some uninstalling/cleaning program to remove all the drivers, prior to installing the new ATi Catalyst ones?
  2. I think there is something major wrong
    It will not stay logged in long enough to to anything even drops off from the Bios screen and re boots ...I was there looking to see if there was something needing altering
    Could it be a power problem?
  3. Possibly. 650 W is more than enough, but what brand is it, and how much amperage is there available on the 12 V rails?
  4. It restarts while you are in BIOS?

    Do you have the problem when you remove the graphics card.

    It says +12 v 29amp -12volt 1.2amps
    Model ATX 680watt
  7. Sounds really dodgy.. 29 A on the 12 V rail, while being a 680 W PSU?
  8. Ok I will have another look ...what should it be to run this card?
  9. Model :ATX 680watt
    AC input 230 volt 50 HTZ 5 amp
    DC output
    +3.3v 23 amp
    +5volt 45 amp
    +12 volt 29amp
    -12volt 1.2amp
    -5volt ...
    +5vSB 2.3amp
  10. Best answer
    I really think 29 A would be more than enough for an HD 4850 system. Then again, your PSU does sound a bit dodgy... might be a really bad PSU.
  11. Anyone else have any ideas?? what else could it be if its not the power supply?
  12. Problem solved :new power supply installed card runs well :hello: :hello:
