Hi guys sorry if this is in the wrong place,

I upgraded from a gt440 to a gtx750 ti, i also upgraded to 8gb of RAM now when i turn the PC on it wont boot. Jist shows a black screen which says f12 to boot in the bottom left corner. My keyboard wont work and the PC beeps and this screen flashes on and off.

I thought it might be a power issue so i tried putting the old card back in and the same thing happens,

Any idea what could be causing it?
 
Solution
Check to see if you have an EUFI or older AHCI "legacy" BIOS. GTX750 came both ways. But sort out the memory first. Get the latest BIOS also memory support can be updated there.
