Hi I have an older computer and it can't seem to boot up. all I get is the Motherboard screen and that's all. its running on Linux and it always booted up but now it does not. is there anything that i can do ? Im not sure what the problem I unhooked the HD and put it back the video card works just fine the mouse and keyboard are non functioning so i can't get into bios at all... Other than throwing it away what else can i do?
