Hi, Could any one help or suggest how to fix my problem?? I have a gigabyte motherboard S-series with a quad-core processor and 2 gb ram. So the problem is that when i turn on my pc , it doenst show any display,

so first i have tried another monitor...

The problem contynued so i thought that it could be the graphic cards problem... so i have changed the graphic card but again the same thing nothing is displayed at all....

also i forgot to tell you that when i turn on my pc i dont hear any beebs.... also in my motherboard there is no any led... working....
all the fans work normaly ( gpu , cpu unit ).
Also the hard drives work normaly i cann hear them.

So this should be my motherboards problem or my cpus??

Thanks in advance :)
