Blank Screen and Dead Mouse...


Which makes me think it's not hardware related....

Hi all - thanks in advance for the thoughts/advice.

When the computer is off and the monitor is on, I get a 'no signal' message on the monitor so I know it's working.

When I turn the computer on, the monitor blinks once and then the monitor power button blinks on and off - as if there is no input (?) but I can't get any display, including the POST messages so I can boot to safe mode.

At the same time, the mouse (optic) is receiving power as I can change the dpi settings but the laser does not power on.

Both of these problems arose simultaneously.

The first time it happened, we just left it on for a while and the both 'came back to life'.

I did shut down the computer and now can't get either to respond, no matter how long I let it run.


Are you getting any POST error beeps ?
If so count them. The number will indicate whatever PC component is faulty.
Thanks Terry - I'll do that tonight when I get home. I'll report back after that.


POST Test reports no errors (beeps) at all. In fact, I can hear Vista load and give me the 'welcome' chime. Just can't see anything or use the mouse.

You haven't got kids or pets that might have dislodged some of the connections behind the PC ?
Seems strange that 2 unrelated things should fail simultaneously.
(nobody spilled anything ?)
Is the mouse USB or PS2 ? If the former, have you tried a different port ?
I do have kids and pets - but I've checked the connections. They're solid.

I tried another mouse and I can get a laser on it but still no response from the monitor. I'm going to try to hook up a different monitor. *sigh*
