	Short followup.. This morning I booted into Windows safe mode, and then did a shutdown.. The computer is shutting down properly when commenced from Safe mode.. I'm starting to think it's a software/driver thing vs motherboard problem/fault?

	Hello All, Looking for some guidance. I just completed a build (Only my second one) and most of it is working as expected. The problem I'm having is when I do "shutdown" from windows, my motherboard appears to remain powered. The CPU fan continues to run, and a light remains illuminated on the GPU, as well as the lights on the front panel of the case. I did a lot of digging on these forums and I think I have done most of what I can. This computer was a "rebuild" of my last one. I re-used the case, HDD's, and PSU (650Watt corsair gold). To be specific, the when I do a shutdown from windows, after it "shuts down" I'm able to power it off completely with the power button by holding it down. This is obviously not ideal. Build consists of: ASRock B450 Pro4 ATX Ryzen 5 2600 EGVA GTX1080Ti SC2 G.SKILL Aegis 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3000 SSD with Microsoft windows 7 Home Premium (This drive was in use with current install of windows on old machine) ASUS DVD drive. What I've done: -Flash/updated Bios to 1.8 -Combed through BIOS settings and disabled "deep sleep" mode. -Moved memory sticks from positions A2/B2 to A1/B1, then tried each individual memory stick in position A1. -Tried startup/shutdown sequence with following devices unplugged: Front panel headers HD Audio connector Front panel USB3 connector Ethernet cable in the back. - Unplugged and verified front panel power/led/HDD cables in proper position, and tried reversing +/- polarity of power sw. Open to suggestions, and I"m really hoping It's something little that I've overlooked. I do want to upgrade to windows 10 but I haven't because I don't want to loose all of the programs that are on the PC now. Perhaps updating to win10 would solve this? Thanks for any info! John
