i am using an ASRock 990FX Extreme 4 Mainboard (with bios 2.0). I installed an AMD FX-6200 processor and i use a be quiet Straight Power E9 CM 680 Watt power supply.
I have the following problem:
When my PC is turned of for longer than approx. 10 minutes and i turn it on again it does not start at the first try. It does not even display the Power On Self Test Screen.
The Dr. Debug displays 36 in this case. According to the manual this means: CPU post-memory initialization. System Management Mode (SMM) initialization.
On the second or third try the PC starts without a problem and runs very good and stable.
When i just press the reset button it does never help. I need to turn the PC off with a long press on the power switch and then turn it on again.
I already tried the following:
Checked all cables for proper connection.
Checked whether the main board is mounted properly in the case.
Started without USB device connected (with the exception of keyboard and mouse).
Started the PC with only one DDR Ram Module.
Loaded Bios defaults.
I did not overclock anything.
The behaviour when starting the PC is always identical: Two or three tries required when booting the PC.
There is no problem when starting the PC from the hibernate mode.
When i received the board i installed the bios v 2.0 right after the first two or three start ups (so that i am not 100% sure whether the problem was not there with the older bios)
I also found that a very similar problem is described here:
990FX Extreme4 Sleep problem with new V2.00 BIOS (second post/ solution described does not help for me)
My next try would be to use bios version 1.8.
Can s.o. please comment whether it is possible to downgrade the bios on this motherboard?
Thnaks for any comments.
I flashed Bios version 1.8 and the problem disappeared. Just in case s.o. experiences the same problem.
I'm having the same sort of problem, after it's gone to sleep when I try waking it up, it wakes up then the keyboard, mouse and video switch off, also have you noticed the volume lower with windows 8? My profile will not update, but bios is 2.0 and windows 8 pro

i am using windows 7 64 bit and therefore did not notice a lower volume. Also i did not have any problem when the system wake up from sleep mode. I only expereinced problems with cold boot.
Why don't you try using the bios version 1.8 as well?
