No Signal to the monitor

[Billly10]

Now i know this thread has been made before but my situation is slightly different, see about 2 months ago my BIOS crapped out and so i ordered a new one, when it arrived i popped the old one out and put the new one in no problems thus far... So i switch on my PC and all of the fans start and i look up at the monitor and it gives me the no signal sign (it doesnt say it but theres this thing on the screen that basically suggests that and it happens everytime the monitor goes off)

So I'm thinking that its either a faulty bios...the wrong bios....or my CPU / Mobo is broken

So heres what i know:
-The PSU is OK b/c i was using it in another pc prior.
-The RAM is fine for the same reason, its been used in another pc and both sticks of 512 DDR1 are OK
-Ive reset the CMOS
-Unplugged monitor plugged back in
-Took out everything except the motherboard and put it back in
-Re-Applied thermal paste
-Did the whole turn off the PSU and hold down the button for 30 secs....

and stil nuthin'

Any help is appreciated

My SPECS-

-680 watt SunTec PSU
-AMD Sempron 3100+ 1.8GhZ (i think)
-1 GB of ram (2x 512Mb)
-Ati X1900 XTX 512MB
-Mobo is First International Computer K8MC51GLF

and yeah i'm upgrading soon anyway..b.c that Card doesnt belong with such a crappy system ^.^


Thanks!
