So this PC is kinda old, bought it back in 2007.

I upgraded RAM and graphic card yesterday, then my pc won't power on, it just does nothing when i try to turn it on using HD 7750 but it works fine with my old videocard.

try this steps from top to below.hope this will work

1)make sure you have connected vga or dvi cable from GPU to monitor not onboard on mobo to monitor

or

1)Remove the gpu , plug monitor cable to mobo's onboard output

2)start pc - go to device manager - display - uninstall whichever drivers is

3)restart pc - put gpu back


or

1)go to bios settings - set primary display device to PEG OR PCI E

or

1)Update your bios to latest
