mixing ram speed is not good for performance.

I would try a new power supply.

i understand,that mistake happened as i bought RAM at seprate time.
i will get new power supply but motherboard does get proper power supply and on starting power button,cpu and chasis fan start as usual.
only thing their is no vga output.

i will get new power supply tomorrow.

thanks for your reply.

did you try a video card?

I keep an old PCI card for this purpose.

also, is the board shorting out on anything?

thanks iron woode for your reply,
next day i took everything apart and rewired everything,i am noob when it comes to building rigs,i had not put copper screws on case to mount motherboard.after putting those screws and then installing mobo on that foundation.everything worked as it supposed.

only question i would ask is can i test motherboard?

any utility to test same?

thanks again.
