I have a compaq computer with 6150se intergrated graphic card. I bought a new graphic card for it but after I finish installing, the screen doesn't turn on. I think there may be a problem with my power supply because the recommended is 400w and I only have 250w. PLz help me out

buy a new power supply.
Did you disable integrate graphics in the BIOS?
actually that will probably do it, but I dont know about your power supply.
