System no longer boots after msconfig Safe Mode setting

With minimal hardware connected. Verify all internal connections, Re-Seat all Pcie and memory cards, Verify all power connectors. If your computer has onboard video use this port for trouble shooting.

I tried all of this and got some debug lights to come on but still no picture. I'll try it one more time but I'm expecting the exact same result.

With the clear CMOS Jumper Enabled. Power on the computer and wait a little until it... Shutdown or reboot or boot normally

I don't have a jumper.

Do you have a Voltmeter ?

No.

Your troubleshooting avenues are starting to be restricted. So it's a reset button you have ? try to hold it while powering on. If you dont have a vom do you have a spare psu ?

I can read that your board is

Flash BIOS Button: Simply use a USB key to flash any BIOS within seconds, without installing a CPU, memory or graphics card

Capable...

You should be able to recover that machine, if it has no other physical problem.

I'm in the middle of my final attempt to reassemble everything with minimal hardware installed. I do have a spare, lesser quality PSU but I don't know if I should bother with it. It would be yet another tedious step with no guarantee of changing anything. I did attempt to use the Flash BIOS button but it didn't work. Always the same problem is no picture on any monitor.

Thanks for replying...

I bare with you on all the steps you have to take to test ALL this.. But you are not forced to install it... Just connect main power, the 2 board power and your video's pcie if required. and fire up... If you are confident that your spare psu is good. It will rule out this avenue.

If this fails. I would honestly begin to think that something is broken If your are confident that you followed trought the troubleshooting steps you had by followers suggestions here...

To isolate the culprit requires another complete working computer of the same "grade" so you can remove everything and try the MB alone... With completely new parts. If it starts. Then replace parts one by one, with the one you have until it doesn't start...

This is easy for me to do at the office... but for someone at home, it can become a very tedious if not physically impossible task.

Error LEDs, increase the likelihood of there being a bad CPU socket.

Really? How's that? The only reason I got the board with error LEDs is because I had no way of diagnosing bad parts otherwise. Never got any beeps, even with a beep speaker installed right where it needed to be.

The error led can also means a bad overclocking profile. Even if you where not... Does Your mobo have a fail safe switch somewhere ?.

I don't know.

If I read well.. You still have a couple of boards coming dead in a very short time on that PSU, isn't it ? Personally I would nuke that PSU, get a new one. And RMA that board again...
