want to upgrade the video in my CQ5300y... have upgraded PSU to 550w, RAM is 4GB, CPU is Phenom 9750 quad core.
I bought a Sapphire Radeon R7 240 4GB but computer does not seem to know it's there, just keeps going to onboard vid. I did change it in bios to the PCI x16.
Is this card not compatible? if not, any suggestions on a good compatible card would be much appreciated.
