Hi eveyone, thanks for reading,
Last week I turned the computer on, it got to the welcome screen and I couldn't move the mouse cursor to select my icon, so (probly really stupidly) I just unpluged the computer at the wall, thinking that if I restart it the mouse will work, when I turned the computer back on, the LEDs on the front came on, and the fan was running, but it didn't beep atall and the monitor didn't come out of sleep mode, and just displayed the message 'no signal'. What have I don? Can it be fixed without opening the comp up?

Also I don't want to open the comp up cause it still has the warranty tag on, which stops me from opening it up, I don't want to take it off, in case its still in warranty, but I know.

Im really stressed, I'm 16, in the middle of my GCSE's, and all my coursework is on the computer, including a piece that has to be in by next week, otherwise I lose 50% of my grade, also my mum doesn't know yet, when she finds out she's going to kill me! HELP!

P.S I have checked all the cables, and held the on button for 30 secs to drain power, but still no signal

Check the connections to the monitor. Try using a different monitor and see what happens.

Checked the cables still not working, I haven't got a different monitor

What are you using to get in here?

I'm using my laptop, my 600e IBM Thinkpad which I've dug out of the closet and using a dail up connection, seen as the broad band won't work

Try connecting the monitor as an external monitor on the laptop. See if it works OK. If it does, then the problem may be your video adapter.

How do I do that?
My monitor and comp are connected, using a cable going from the monitor, to the comp. and I don't have a cable to connect my laptop

Your laptop should have a vga connector on the back yes? Does your monitor have a VGA input? Connect the VGA cable from the monitor to the laptop. This will determine if the monitor is working fine.

Most laptops have an external monitor jack. Just unplufg the monitor cable from the computer and connect to that jack.

Yeah your right, I pluged my laptop in an it came up on the monitor, so there can't be anything wrong with the monitor then... right?

OK, os the most likely is the video adapter. Now the question is whether your adapter is on the motherboard or not. If the VGA jack is in one of the slots, then its not. If you know someone who can loan you a video card you can test it out.

I don't have anyone I can loan a video card off

OK I've decide to open it up seen as the warranty is out on it anyway, what should I be looking to do? And what should I definitely not touch if I don't want to break my computer?

It's a 'EM-170 LCD MONITOR TFT' don't know if that helps, by the way I think the monitor works cause it worked with my laptop, so do you think a novice would be capable of changing a graphics card, also would I be able to use the graphics card from my laptop?
Esuming it's the video card that's the problem ofcorse

No, there is no separate card in the laptop. Changing a video card is not too hard.

I reseated the grx card, still nothing, I'm getting a cheap one tomorrow morining, is there anything I can do in the mean time?

If the current video is on board, you may need to disable it. This is done in the CMOS setup.

How do I know if its 'on board' or not? Also I read that it might be a good idea to clear the CMOS what effects will this have?

I mentioned earlier to look where you plug in the monitor. If the jack is in one for the slots, then it's a separate card. If its among the pother ports, its onboard.

Who told it was a good idea to clear the CMOS? Definitely not something you want to do.
