pc wont switch on

Hope someone can help, my computer crashed and when i restarted it it just wont come back on at all. I keep getting check signal cable message come up. The lights on my tower are on and ive tried 3 different monitors and it keeps saying the same thing, so it seems to be the tower although the power is going to that because the lights on the tower are on, ive checked all the cables. I hope someone here can help.

thanks

open it see if any little or big cables might have unplugged.
Does it allow you to get to the Bios?

 

no nothing just says check signal cable, the tower is on i can open the drawers on it, so the power is going to tower.

thanks

 

Ive had a look inside and i cant see anything loose but the tower must be working because the router thats connected to it is still sending the signal to this computer upstairs.

Any suggestion are much appreciated
thanks again

 

have you tried to boot the pc of a floppy?

 

No i havent tried that, wat do i do. The computer was given to me without any discs, i havent got any recovery disc or anything like that.

 

what he meant was; have you added any cd/floppy disk in ur pc at the moment?

 

Check the cable between your monitor and video card. It must be loose.

 

Its not doing anything, when i switch it on the lights on the tower come on but a message on the monitor says check signal cable, now ive tried 3 different monitors with 3 different cables and it keeps doing the same thing, its as if theres nothing going thru to the monitor.

 

Try clearing the CMOS. Check your motherboard manual to find out how you doit.

 

I think it could be the same problem ddp helped me out with, have a look Kala21 - http://forums.afterdawn.com/thread_view.cfm/463203

I had to reset the video card a few times but it worked in the end.

Good luck
