I was give this. eMACHINEid
Intel Celeron
128Syne DRAM
20 GB HDD
128 L2 cache W/66MHz Bus
3 D agp Graphics
56K Modem

An they didn't kill it before giving it to me.

There is no pointer on screen. I TRIED a PS/2 an a USB mouse.
I tried the options in set up for the mouse no change.

Does the keyboard work? If so...using your keyboard...navigate to the control panel/system/hardware/device manager and see if there are any issues with the installed mouse. You may have to find and install drivers for the mouse...be it USB or PS2.

Other issue may be the mouse port is bad. If so...take it to a tech.The mouse cursor should APPEAR on the screen regardless of whether it senses a mouse or not. Could be weird mouse or display drivers.

If the cursor does not appear even when BOOTING with no mouse then its PROBABLY software/driver based. (I'm guessing here that the OS is like XP or Vista, because I know the cursor will show, even with no mouse).Did this computer come with any CD's? If so, which ones?
