Ok here we go, the guy above is right in the sense that your video card is broken, but what he didnt check is if its onboard video or a seperate video card, can u say which it is? and also if it is onboard video, do you have an agp/pci express slot(pci express is NOT the same as standard pci), the problem you are describing points to whatever video adapter you are using, does the pc beep in any way at all?

How to install wirless mouse

It depends on the wireless technology used by the mouse.

1. Infrared
If your mouse used Infrared for communicating with your PC, you will have to place an Infrared receiver on your desk, in line with the mouse you want to install. You will definitely have to install the drivers supplied with the mouse/Infrared receiver.

2. Bluetooth
If the mouse uses Bluetooth, first you either will have to install a Bluetooth dongle on your PC/Laptop (if it doesn't have Bluetooth integrated) or activate the Bluetooth on your PC/Laptop. Then, using the Bluetooth software supplied with the dongle or PC/Laptop, search for new devices and choose the mouse to pair with. You may have to install the software provided with the mouse for if to work.

E-machines T3624 windows xp unit powers up but the monitor reads no signal , the keyboard lights all the lights in a blink but doesn't command , the mouse isn;t recognized

The fact that the monitor displays the "no signal" message confirms that your monitor is getting power and switching on but it's not getting a signal from the graphics card, either due to a fault with the RGB cable between the PC and monitor or a fault in the graphics card itself. If you're convinced that the cable is fitted securely, then the next most common cause of this is a loose or defective graphics card. Taking appropriate precautions against static electricity, open the system case, remove the graphics card and then re-seat it carefully but firmly in the slot (you'll need to disconnect the monitor cable first). Make sure that the copper contact edge is making a secure (i.e. relatively even) connection across the whole length of the card.

Do you hear any beeps? Is this a new problem? Were things OK before?

Are you familiar with opening the case? Do you have the manual?

Inside you can:
Check if the fans run; clear the CMOS;
Re-seat the RAM; Vid Card; CPU; those would be initial tests.
Check for red lights on the front of the case & or the board itself.
If no beeps try starting with the RAM removed: any beeps now?

Let us know if that helps

Try connect your monitor to some other box and try if it works the same way or as a normal pc boot. If it works well with other box, the issue is with the BIOS. Get the BIOS flashed with the latest version of flash program for the Bios chipset which your board is using. If the monitor shows the same symptom on a different box too.. you may need to get your monitor repaired. Good Luck

BIOS intermittently loses CDROM

Hi, first check that your RAM chips are seated firmly, then check the CPU fan for dust, then if you still have the problem try disconnecting the on/off switch wires that run from the case to the board, bridge the two pin out to mstart the computer and see if problem still exists. The final test I can offer is the power supply, If you can use a multimeter and test the voltage. Yellow =12v red=5v black=ground. If you get a variance of more than 2v replace the unit. Another way is to try a diferent power supply. Regards mistyman
