i recently got a very old computer from my grandpa to tinker with. it has a socket 754 amd sempron 3400+, 512 mb of ddr memory, and nvidia 6100 graphics which i believe is chipset graphics. i plugged a monitor and peripherals in and right when i plugged in power the case fan and cpu fan spun up which i thought was weird as i didnt press the power button yet but the monitor said no input so i pressed power button but still nothing. i opened it up and did the regular stuff like re-seating memory and stuff but it still did not want to output to the monitor. i tried shorting the front panel power button pins but still nothing. is something dead?
