I found an eMachine T2642 around my house. Its a few years old, but still worked fine so I bought more RAM for it [pqi DDR-266 PC2100 512mb] I know its supported and the maximum RAM for each slot is 1 gig. When ever I start the PC with the new RAM in the BIOS recognizes it but when it gets to where the windows loading screen should be the monitor kicks off, the computer stays on and when I turn the computer off and restart it gives me the boot options menu and every time I try to start Windows safe mode or normally the monitor turns off. I have tried it with just the 512 stick by itself and the same happens I've also switched the slot it was in. It only boots with the original 256 stick in. Can anyone help me I would like to have a spare computer.
