Hello,
I recently just went and bought a new GeForce GTX 550 and a larger power supply, installed both in my HP pavillion (which i just bought last month). When I turned it on I heard windows start up but there was no picture. I tried putting back in the card it came with but that got me the same result. I switched to the onboard video card and the computer came on (with very bad graphics) I tried installing the drivers for the new video card (both from the disc and Nividia web site) but I keep getting an error saying no compatible hardware is detected, even though my new card is plugged in. I checked in BIOS and my PCIe slot is enabled. SO im totally at a lose and starting to freak out that I just dropped a grand for giant paper weight. PLEASE HELP!
