Situation is, just built this machine:
Gigabyte UD3H-B3 board
550 Ti EVGA
16GB Vengeance
60GB SSD for Windows 7 64 Bit
Corsair 800 Watt PS
Intel i5-2500k
etc...
Now, been built, working fine for 2 months....but I took out 550 ti to sell it because im going to upgrade...everything worked fine, video...post...booted to windows. Perfect. Now that i've taken card out, using the motherboards VGA it will post, I can get into BIOS, but when it ends it post, shows the hard drives, cd roms, etc....the Motherboard beeps and monitor says "no signal input", this is where I dont understand why it wont even show windows is starting, what is causing it to stop where its supposed to load the OS, any input would be helpful as I have a PC that posts but wont boot off Mobo's VGA.
