Any beeps when you switch it on? Any changes to the PC lately, crashes (or more frequent crashes), blue screens? Any strange noises from the unit when it's on? Possibilites include overheating (and subsequent damage to the CPU) or failing power supply. If the guarantee has run out you can take the side off the machine and see if loads of dust and fluff has collected inside and around the fans, that would point to overheating, but it sounds as if the damage has already been done on that front.

Do you know whether you have integrated graphics or a separate card?
Either way it sounds as if the display system uses some of your RAM for itself.

Did you put in the new memory chip before or after the failure?

If the stuff on your HD is as valuable as you say it would be wise to remove the HD temporarily and either put it in another computer as a slave, or in a powered USB case and backup its data contents before anything worse happens.

Above all, don't try and interfere with the OS and contents of the HD until you have a normal display again.

Once the display is back on the monitor you can reconnect the HD.

With the HD disconnected the computer obviously will not boot, probably saying no disk or operating system, but at least you will by then have the graphics working again to see that.
