I have a HP Pavilion P6-2035uk computer. The specifications are as follows :
Intel i3-2120 3.3Ghz (dual core)
HP Cupertino motherboard
Win7 64 Bit version.
Intel HD Graphics.
I want to get a nice card which can run games at 1080p resolutions. I was looking at the Radeon 7750 , GTX 550i and the Radeon 6870. I purchased the 7750 and it won't work on my computer. The fan spins around on the card , but nothing shows up on the screen even if my monitor is plugged into the onboard graphics or the card. My PCI-E slot uses 2.0 format , whereas the 7750 uses 3.0 -- Could this have something to do with it? I'm going to send it back to the shop and get the 6870 but I'm not sure if it will work . Can someone verify it it will?
There is no reason why a Radeon HD 7750 card won't work on your computer. PCIe 3.0 is compatible with PCIe 2.0. Make sure tha you are plugging your video cable into the graphics card outputs and not the motherboard. When you install a discrete graphics card, the onbaord video is disabled. The documentation for the motherbaord clearly states that "Either integrated graphics or the PCI Express x16 slot are usable at one time; they are not usable concurrently." Check your specs here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02...
Have you downloaded and installed the graphics driver for the Radeon HD 7750 from http://support.amd.com/us/Pages/AMDSupportHub.aspx ? The problem could be your power supply. 300W is pretty slim for using discrete graphics. AMD reccomends using a 400W or greater PSU with the 7750.
I would recommend that you replace the PSU before anything. Something like a Corsair Builder series 500W or a Seasonic M12II 520W would do the job and give you the flexibility to use a better graphics card.
