My problem is with my ASUS M4A78T-E motherboard and an intermittent POST (Power on Self Test). I am posting this topic from the affected computer in Windows 8.1. Which means it POSTED (power on self test) and booted into Windows 8.1.
When I shut down the computer from Windows. It will not POST again. To make it POST and boot into windows I must:
1. Turn off the power from the PSU (power supply unit), it has a switch with a -/o
2. Wait for the green light on the Motherboard to turn off
3. Turn on the switch from the PSU
4. Wait till the green motherboard light turns on indicating power
5. Press the power button on the front of the computer
6. BIOS screen shows CMOS battery Low F1 for setup F2 to load default values and continue
7. Hit F2 and Windows will load
Specs:
AMD Phenom II 955BE 3.2Ghz
ASUS M4A78T-E (stock BIOS)
Corsair 8GB (2 x 4GB)
Integrated graphics
Other info:
I tried this with 2 separate PSU's and it does the same thing. I removed the MOBO from one case and put it in another, the CPU was never removed, just cleaned and used a different cooler. The RAM is the original RAM I've been using with it for 5years. Basically the only thing that's been done to the system is that I removed the graphics card (AMD 7970) to use in a new build and want to use this system with it's on board graphics.
What could be the problem?
