    Great. First my laptop and now my PC. When I switch my PC on I get a message saying 'no input signal' followed with a double 'beep beep' noise which goes on for a bit. After reading some advice found through Google, I tried (and failed) to undo the back of the processor unit. I undid all the screws but the damn thing still wouldn't come out??! Anyways I dusted of as much dust as I could off the machine and put it back in place but still doesn't work.

    I guess firstly what's up with the comp?? And secondly is there some special way of opening the back of the processor unit??

    Ta.

    I don't understand any computer technical aspects. Also my comp. doesn't switch on to a point where I can do anything, the screen is just black with this message in the middle.

    The beeps are likely to be a bios error code telling you something is very wrong. It's likely to be related to CPU, RAM or Graphics card either than one of them is broken or that they've not in their slot properly.

    If you can get into the system unit then you could try reseating the various components. If not it's probably time to find someone who's good with computers and/or buy a new system.

    What's the make and model of the machine? The beeps are a code, as every time you start the machine up it does something called POST, which checks the system. The beeps are telling you something's wrong, and if we can find out what the BIOS is, the 2 beeps should help find out whats wrong. Here's a useful website http://www.computerhope.com/beep.htm
