Test in another system if possible, or try a different card in this one. If the display is still blank, then video card is probably defective. If you hear beeps, re-install the video card. IF you don't hear beeps then either the RAM is bad, or the MB/CPU has died If the RAM is good you should hear beeps indicating no video card installed. If the system starts to POST with the on board video, re-install the video card and continue below after "If you hear beeps, re-install the video card."

If the screen is still blank, then either the RAM is bad, or the MB/CPU has died.

You should hopefully see the system start to post, and get a keyboard error. Re-install RAM - if the system will work with just one stick installed then install just one stick, and try to boot again and choose the appropriate section below: try 3-4 times, unplugging the power in-between tries for at least 60 seconds. Try to boot the system - some systems will give a beep code with no RAM, some won't. If the MB has on board video and you remove the video card connect the monitor to the on board video portĬheck that CPU fan/heat sink is mounted properly and FAN is plugged in.Ĭheck that case speaker is connected properly - Did you normally hear the one beep when POST finishes before this problem started? - If not, try to test speaker on another system - if the speaker is bad you won't hear any beep codes If that doesn't work, or the system doesn't have on board video then we need to remove everything and see if we can determine if it's the MB/CPU or an add in card/RAM If the MB has on board video and you are using an add-in card, remove the video card and hook the monitor to the on board video. If you are not familiar with good anti-static procedures, then as they say Don't try this at home or you may damage other components. NOTE: Before removing any components be aware that static can easily damage components. I'm assuming you've checked the monitor on another system, though with a dead monitor you should still hear the normal startup sounds, single short beep indicating POST was successful, windows start up sound (assuming it boots directly to desktop) etc When you turn the power on, does the CPU/Case fans spin, do you hear the hard drives spinning up? Some motherboards have a way to recover from a bad flash, even when the system won't post so will need to look up the manual to see if that is possible. Since this all started with errors with awdflash.exe I suspect the BIOS may have been flashed with something it shouldn't have and now the system won't even boot.

Before buying the new MB, there's some things to try.
