No signal to monitor and keyboard lights flashing

[account_disabled]

Hi,

It was all working fine until March when the screen picture started

going wobbly. Then it started flickering onto No Signal Or Cable

Disconnected. Until finally it is not showing any signal to the

monitor at all. I checked the monitor (an old VGA style one) and it

works fine on another computer so the problem MUST be with the PC.

The monitor is plugged into the blue VGA socket on the back which is

the onboard connection and NOT a seperate video card.

Now the computer just powers up and then starts the keyboard lights

(Num Lock, Caps Lock and Scroll Lock) flashing together

intermittently. I can also hear what I'm sure is the DVD Drive

clicking slowly and I can see the fan is running OK over the processor

chip. But that's it!

I have tried unplugging things from the motherboard and re-plugging

them in but it doesn't change anything!

Any suggestions or diagnosis would be greatly appreciated!

Please help.

Thanks!

I didn't find the right solution from the Internet.
