Help please. No display on computer monitor

[shrek2]

Hi Guys. Yesterday I swapped Graphics cards as the 8500Gt I had broke.
When I put the new card in and booted up, it said overclocking failed and put me in the bios. I set everything to stock clocks and bam it rebooted and I haven't been able to get a display on my monitor.
I thought it was the mobo so I went out and bought a Gigabyte P35 and still the same so I don't really know where to go from here. I have ordered new ram from ocuk as I have Crucial Ballistix ddr2 667 so I don't know if that is the problem really.

Any ideas where I go from here?

Well I would have suggest a CMOS reset, but you've changed motherboards completely so that wouldn't be my guess. My first point of call would be addressing the GPU and if possible getting a very cheap PCI (not PCI-E) graphics card and installing that in the system, use it to boot up with and check if your main graphics card is getting detected in Windows in case it's died on you.

This is annoying. Reckon its a cpu or memory fault?
