So even after you did all that, you get no post error, no lights come on your motherboard ?
If thats the case I'm going to say his motherboard has finally had it.
Only way to confirm that is take it to a computer shop and have them test it for non post.

Try pulling ram out individually.
Try booting without the Hdd.

Then Try booting without anything attached. (No Ram, no i/o devices, no HDD, no optical devices etc) you can keep monitor plugged in

I know you said you tested the PSU, but do any of the fans spin?

*After all these are tested then you can start to assume its the MOBO. Although i highly doubt it is. - Check for burst caps on the board while your at it

lights come on ..I can here the hdd just spin but not like its reading and all fans come on. I also disconnected all devices accept for psu and monitor still no display...well I went ahead and ordered a new cpu hope thats the prob

When a keyboard is attached do any of those lights flash?
Mainly the caps lock?

 

[mustwatchtv]

yup lights flash......crazy thing just happened just plugged back in the comp and now Its froze on bios screen

Okay well that indicates that it's the motherboard..
If you can cancel/return the cpu it might be best, unless you'd like to try it yourself first

ok found the problem ...both my computer ram and my "test ram" was bad which led me to believe it was something else...DAMN...oh well I got a cpu coming in the mail

thanks to all who helped out
