i did all the things reinstalling connectors, even take out my mobo for it from casing nothing happening .. some one told me that coolermaster xtreme power 600 isnt that good. any one running with it ??
Assuming you didn't change anything else, its either a bad card, or your psu doesn't have enough rails and/or the rails aren't balanced. Is the card connected to the psu via pci-e from the psu, or from molex adapters?
So when you boot, you see the POST screen flash?
Hit F8 until you see the options for safe mode and such; go down to vga mode and boot that. Your resolution will be really low, but you should be able to see stuff.
From there, install the drivers, restart, and you should be good to go.
