As long as the mobo has onboard graphics but you need at least 1 gb RAM installed otherwise it wont boot...you should see some life from the system. Do you get the post beep? Is the PSU light on?
What make and model mobo do you have? Does the mobo have onboard graphics? Did you use a anti-static wrist band when installing the hardware to prevent static shock which can be deadly to hardware.
An upgraded CPU and especially a more powerful graphics solution are likely to demand more power. Did you ensure the PSU is able to support this upgraded hardware? Also note graphics cards often require additional power connections directly from the PSU.So tomorrow I'm just going to get a good motherboard and go from there.
Sure! What information can a graphics card display if board it is installed on does not work because the CPU is not working? The computer will not make it past the very first stages of POST if no CPU is detected.I can’t get any video so can a bad CPU not even give you video and how likely it to get a bad CPU?
