unexpected shutdown and reboot

Hello Gus--

Code 9f BSOD almost always points to a pure hardware problem causing a
forced shutdown for a few reasons.

The most common are:

1. Grounding problem with your case - Your motherboard is seated improperly
on the brass motherboard standoffs, and it is causing a short on the
motherboard. This can also affect how well any expansion cards or video
cards sit in their slots. Try reseating the motherboard or booting it
outside the case on a non-metal surface (preferably the non-static bag it
was wrapped in).
If its still shorting out when you place it in the case, try using the
plastic or paper spacers that sometimes come with a case, or using big
squares of electrical tape on top of the standoffs and screw right through
them.
2. No fan plugged into cpu fan header - You need a fan (any small fan will
do) plugged into the CPU fan header initially until you turn off fan
monitoring in the bios.
3. ATX 12v connector unplugged - You forgot to plug in the square 4 pin
power plug with 2 yellow and 2 black wires. It is located behind the
heatsink bracket, near the top left corner of the motherboard. THIS THE MOST
COMMON CODE 9.F PROBLEM.
4. Heatsink bracket overtightened - The screws should only be barely
tightened, NOT tightened to the point the screws can't turn anymore. When
overtightened, it will cause the motherboard to warp near the RAM sockets,
and the RAM will not seat properly (especially in the middle). Make sure and
support the board with your fingers underneath the RAM sockets gently
applying pressure while you insert the RAM. This problem is also associated
with code 0.4
5. The only other issue that code 9.F refers to is insufficient power. Make
sure your PSU meets the minimum requirements of atleast 350 to 400 watts and
18-20 amps on the 12v rail. For High-end setups with multiple hard drives,
high-end video cards (especially Geforce 6xxx series), multiple case fans
and/or lights, make sure you have atleast 400 watts and 22 to 24 amps on the
12v rail. If the PSU has 2 rails, add them and make sure they meet the
minimum."

Good luck,

Possible causes are
1. power supply faulty or poor quality, your machine needs a minimum of a
350w and Intel /AMD certified
2. faulty RAM
3. overheating; check CPU fan and blow out any dust from heatsink fins
if present

Thanks for all the input. I will check out these things!

Hi,

BCCode 116 (or 0x00000116) is usually video driver related. You may need to
reinstall or update yours with a fresh set from the manufacturer.

Sorry to reopen this thread again but i have am ibuypower gaming
notebook and it has a lot of wierd sleep errors were i will try to go
into sleep mode and it will turn off the screen but the system will
continue to run but won't take any input. When this happens i usually
do a force shutdown then just start it up again or i can leave it for a
while and it will eventually shut down on its own but when i start up
again it gives me the bluescreen 9f error. I looked at some of the
suggestions and i know it cannot be the power supply and it would be
rvery very difficult to remove the motherboard because it is a notebook.
Does anyone have any ideas?

The blue screen 9f error occurs if drivers do not handle power state
transition requests properly, usually during one of the following
procedures:
Shutting down
Suspending or resuming from Standby mode
Suspending or resuming from hibernation

To resolve the error and prevent the error from recurring, update or
remove the offending driver. This error can occur because of a device
driver, but it can also occur because of a file system filter driver
(for example, a driver that is installed by an antivirus, remote
control, or backup program).
