I've just put together a home theatre pc for my stepdad to find that it turns on, and has no screen input.
Specs:
Thermaltake DH101 with Media Lab VF7001BNS
Creative Sound Blaster X-Fi Titanium PCIe
ASUS M4A78T-E Motherboard
Samsung SH-B083A Blu-ray DVD Combo Drive
Western Digital Green 2TB WD20EARS
AMD Phenom II X6 1055T $
Corsair TW3X4G1333C9A (2x2GB) DDR3
Corsair HX-750 Power Supply
I have tried:
Different PCI-E slots for the GPU
Different GPU altogether (in both slots)
All combinations of RAM slots, including only one stick.
When I have my 3870X2 in there, the D25 diode flashes red, and the card whirls the GPU fan continuously. Like a WHOOOooooshh. WHOOOoossh.
All the fans turn on, everything appears to be on, but there is just no screen input. I've also tried the motherboard's DVI connector since I think it has onboard graphics too.
Any ideas on what could be the problem?
Maybe a fucked up motherboard? Try using another motherboard, and if it works, then you can just return it.
I'll try using RAM from my desktop since it's the only other ddr3 ram I have. I won't be able to swap out the motherboard without swapping out most of the other parts too since they're different sockets and ram types etc.
I had this problem once. Processor had bent pins :/. Pretty sure that's the problem.
The only thing I can think of that might actually be malfunctioning is either the motherboard, which can't be the case since everything else powers correctly and all lights come on, or the CPU, which is the only thing I haven't checked yet. You might be right. Shit.

Oh and yeah I had the same problem with the DDR3 from my main desktop in the HTPC, so it's not the ram at least.
Pull out the RAM modules, if the PC doesn't beep when turning on then your Motherboard or CPU is dead.
Could it be the cable?
Last time my pc said no screen input the graphics card had died so that could be your problem.
when this happened to me it was because i needed to switch the monitor out of analog mode
Check out all of your power plugs unplug them and replug them in.
oh yeah btw
the motherboard was DOA
swapped it out and bingo
i knew it wasn't my fault
