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

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?

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?

Possibly. 650 W is more than enough, but what brand is it, and how much amperage is there available on the 12 V rails?

It restarts while you are in BIOS?

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

Sounds really dodgy.. 29 A on the 12 V rail, while being a 680 W PSU?

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.
