Solve : Urgent help please!!?

Answer»

My desktop has power but the monitor says no signal, tried a new monitor still has no signal. Thinking there could be a problem were the connection is, as the keyboard seems to turn off and on randomly. Looking for suggestions, as I really need some files off this desktop, ASAP.  Is there another way to hook up a monitor other than the vga (this is an older desktop)?
Hi try these steps...
1) CHecked video card - I replaced with an old one which definately works and still no activity. I then thought it could be the AGP slot but when I put the original card back i removed the power connections for it and it started beeping, so I presume the slot is OK? Not sure though.

2) Made sure all cables were in correctly - yes

3) Removed CMOS battery and replaced - no difference

4) Memory - removed one stick - no difference, removed other stick - no difference.

4) CHecked CPU - seemed to be seated in correctly but removed and replaced anyway, again no difference.

5) Monitor - monitor screen works as it displays 'no signal' when it attempts to boot.

What is the MAKE and model of the computer, or if the computer is a custom built, can you LIST the hardware?

If it's a custom built, does it have a built-in video CHIPSET or a video card? If it has a card, make sure the card is seated PROPERLY (you can even pull it out and push it back in). Check the VGA cable and make sure none of the 15 pins are bent or missing. Check the VGA port on the card or motherboard and make sure it isn't loose or damaged.

Remove and reseat the memory (RAM).

Is the power supply working properly? Try swapping it out with another known working power supply if you have one available.
