I wonder if anyone can shed a little light on the problem I'm having. Came to start up the laptop this morning and was presented with a very strange display of lines and an attempt at the HP start up logo. The whole screen was a mess of lines and it looked as though the video signal wasn't being processed properly. After a trawl through some of the threads on here I remove the memory module and cleaned the contacts. This did not alleviate the problem. I then found a copy of the service manual for this machine and set to diagnose the problem with that. I tried starting whilst pressing F10 (the default key for bringing up the boot menu on this machine). This seemed to take me to the boot menu - I was presented with a BEEP BEEP BEEP because I was still holding the key down. What I didn't get was any visual information on the screen. It was just black - rather than the off black colour off a screen with no power going to it. I tried using the up and down keys which gave a beep, but the left and right didn't beep - making me think that the cursor was at least moving somewhere.
What could be causing this problem? Has anyone come across it before? As far as I am aware the hard drive information should be recoverable if connected to another machine. Am I right in thinking this?
Any help would be appreciated.
By the way, I think it is running SP3, but I can't be certain of that. I use the auto update function so in theory the system will have all necessary updates in place.
