New PC, integrated graphics not working

[Jasio-]

Hey there,

I just got a new computer with a Gigabyte M68MT-S2P motherboard.
With everything installed, including graphics card (GTS 450), the monitor said no input signal (the monitor works on other PCs). Trying with just the integrated graphics, still no signal. Ive taken out the ram, switched it around, used one stick at a time, unplugged all peripherals, and anything out of the blue I could think to solve this issue.

Any ideas, or if the motherboard just seems to be a dud, let me know.

Thanks in advanced

Try booting the PC from a Windows disc.

Has it been like this from day one, how long have you had it and did you change anything before this problem occured.
