Hi, i have an Acer Veriton M464 computer, the lights come on when you push the power button but nothing else happens not even a motherboard beep or keyboard lights flash. The Cpu fan and PSU come on but nothing on the monitor or even a bios splash screen.I tried a Post Probe card and it came up with a code of D4 and D5 (mostly D5). I have lost my Post Probe manual so i am unable to make out what it means. Anyone have any ideas what the problem could be. It's says Ami bios on a sticker.Thanks in advance.
