I have removed my hdd, dvdrom and other peripherals from my machine while getting rid of some dust. I wanted to upgrade my memory to DDR400. I only used 1x 512 DDR400 and 2x 256 DDR333.
The poblem I'm having now is that the motherboards starts and then goes of in about over 5 seconds. I have plugged in only 1x 512 DDR400, which was plugged in originally and my monitor and keyboard. When I start the machine the screen does not display anything and thenm it goes off in about 5 seconds.
Unfortunately my internal speaker has broken for quite some time. So I will not be able to identify any beeps.
Please help me to get a general idea what could be wrong. Do I scrap it or is it salvageable?
