All of a sudden while working my ASUS p9x79 LE running windows 7 64 trouble free just shut off. No warnings. Instant shut down like power loss.
Checked power, ok. Checked surge protectors, ok. Checked: all connections, ok. Began breadboarding. Removed all components and re plugged 1 ram in A1, machine starts to ASUS BIOS. Re plugged video card. Re plugged coolers, fans, usb, front panel conns, etc. still running, CPU temp normal, coolers working, All RAM show ok.
The moment I plug in any PERIPHERAL connection as in the CD/DVD or the only SSD (1) it immediately dies. Replaced the power supply with new known good from another system I just repaired. Same problem.
The CPU light on mobo was not on during this before and after breadboarding and while it was running on the bios start up screen.
I then notice the bios version is the default original ASUS, I go to ASUS and get update onto a fat32 USB, extract, place on root, it runs and fails update. Now no bios. I clear CMOS and remove battery, replace, recon cmos to 1,2. No start. I grab older BIOS the BIOS update will not run now. Now I cant even get to the BIOS set up screen. However the fans run and the light is on, no video output.
Now when I press the power button on front panel with power on the fans start and the CPU light is red, no video to monitor, no bios screen, green power light is on,
Now when I insert BIOS USB the USB Stick gives me a blue light. When I press the BIOS update button for 3 secs it starts to flash and then 1 sec later the USB stick light goes out, like it lost its 5v and the BIOS light turns solid green indicating the update failed and stops. So it will not even go into the USB update.
Any ideas what else I can do next? To restore my BIOS?
Any ideas why the mobo shuts down immediately with a known good power supply when I connect the power to the SSD or CD? I swapped the same power supply to another system and it runs. What causes the power supply to immediately shut off when it sees the SSD or CD?
