WINDOWS HANGING ISSUES SOLVED

Post by Admin on Fri Sep 23, 2016 1:02 am

Even though Windows 7 is a big step forward
from Windows Vista, it still has it’s share of
problems. I’ve had numerous issues with
Windows 7 hanging when performing routine
tasks on my computer. I’ve tried to collect as
many solutions that I ended up using in this
guide. Hopefully, someone will be able to fix
their problem by looking here rather than
searching a bunch of websites.
I’ll try to make the guide more navigable by
using section headers to identify what type of
hanging I’m trying to deal with. That way, you
can simply skip down to the part that you think
might address your issue. Feel free to comment
with solutions/questions!
Hanging While in Windows 7
If you are already logged into Windows and are
having problems with Windows 7 hanging while
opening programs or clicking on dialog boxes or
right-clicking, etc, then you should try the
following procedures. Usually this means there is
some software installed on the computer that is
causing problems with other aspects of Windows.
It could be an anti-virus software or just a
normal program you downloaded off the
Internet. Either way, the best way to see if this
is really the issue is to perform a clean boot.
Step 1: Log into Windows 7 with Administrator
rights, click on the Start button and type in
MSCONFIG in the search box.
Step 2: Click on the General tab and and choose
Selective Startup . Make sure to uncheck the box
that says “ Load Startup Items“.

Now click on the Services tab and check the box
that says “ Hide all Microsoft services “. Then
click on the Disable All button.
msconfig
Click OK and then restart your computer. If you
find that Windows is not hanging anymore, then
you can be 100% sure that it’s a problem with a
third-party program or service. There is no easy
way to determine which startup item or which
service is causing the problem. You basically
have to manually figure it out by re-enabling
half the startup items and then restarting. If the
problem comes back, you know that the problem
item is in that list of checked items. Then you
check half of those and restart again. You would
have to do the same procedure with the services
if it’s not a startup item causing the problem.
Eventually, you will only have one item checked
and that will be causing the hanging.
Once you know what program it is, go ahead and
uninstall it. Uninstalling the program will also
disable any services associated with that
program. Then you can go back to the
MSCONFIG utility and choose Normal Startup.

Windows 7 Hangs at Startup – Classpnp.sys
One of the more nasty hanging issues in
Windows 7 is when it hangs during the boot up
on the “Starting Windows” screen. I’ve seen this
issue with many clients and boy it can be a real
pain because a lot of the recommended fixes
(using system repair or system restore) don’t
work!
If you try running Windows 7 in Safe Mode, it
fails at Classpnp.sys. What we figured out was
that this issue could be related to a couple of
things. The first thing to try is the startup repair
or system restore using the DVD. You can read
online how to boot from DVD and get to these
options. There are a ton of guides out there, so I
won’t repeat that info. Just make sure to go into
the BIOS and set Boot from CD/DVD as the 1st
priority above Hard Disk.
If that doesn’t work, try restarting Windows in
Debugging Mode. You can restart the computer
and press F8 to get a list of boot options, which
includes Safe Mode, Last Known Good
Configuration, etc. Sometimes Windows will load
in debugging mode and then you can restart the
computer and it will start up in normal mode
fine.

Now the real problem comes in with people who
try to use the DVD and it hangs on “loading
files”, which means you can never even get to
the system repair or system restore options. That
usually means it’s a hardware problem. Some
people have gotten stuck at the classpnp.sys
part after performing a Windows update, which
means it could be related to software.
– In this case, you can try Last Known Good
Configuration or try booting into Safe Mode and
then uninstalling any Windows update by going
to Control Panel – Programs dialog. If you can
get into Safe Mode, you can also try running
chkdsk, sfc /scannow, or trying a system restore.
– If it’s hardware-related, you need to examine
how old your hardware is and if anything could
have possibly failed. For example, a bad memory
slot can cause this issue. Remove one memory
chip at a time and see if the issue goes away.
Make sure that the memory is properly inserted
into the slot. A lot of times the memory doesn’t
get pushed in all the way and it causes all kinds
of crazy issues. Also, try to replace the memory
chips and see if that works. It’s amazing how
many chips go bad.
– If you’re having this issue on a desktop, you
need to open it up and check to make sure that
all the cables and all the cards are properly
plugged into their respective slots. Make sure to
check the power supply and ensure that the
power going into the motherboard is OK. If there
is a lot of dust in the system, use some
compressed air and clean it out good. This may
sound like a bit much, but if you can’t even
boot the DVD without it hanging, you have a
hardware issue, not a software problem.
– Next, you need to go into the BIOS and disable
all the hardware including USB ports, sound
card, floppy disk, 1394, media card, network card,
etc. Try to use the internal/onboard graphics
card rather than the dedicated card. If you can’t
disable something, try disconnecting it. For
example, if you have a DVD drive(s), then go
ahead and disconnect them from the system
internally. I’ve had a client whose DVD drive was
causing the system to hang. Try to boot up now
and see if you can get past the hanging screen.
If so, then it’s definitely a piece of hardware
causing the issue.
– Another piece of hardware to check on is a USB
multi-slot card reader. If you have it attached to
your computer during boot up, it can sometimes
try to use that as a boot device and fail. Go
ahead and disconnect any peripherals attached
to the computer.
– If you’re using any kind of KVM switch for
multiple keyboards/mice, then go ahead and
unplug that and plug in a PS2 mouse/keyboard
into your computer. A lot of those KVM switches
use USB and for whatever weird reason, it can
cause problems with the boot process on certain
machines.
– Also, others have had success by changing the
HDD settings related to ACPI. Try enabling and
disabling this feature and try to restart your
computer. There are a lot of settings in the BIOS
and you can try to go through one by one and
change a setting, restart, and if it doesn’t work,
then change it back and change a different
setting. It’s impossible to say what settings in
the BIOS can make the system hang, but a good
number of folks have had success by changing
settings there.

– Speaking of hard drives, you can also check to
see if your hard drive config is set to RAID. If so,
change it to IDE. This may allow you to boot
from the CD/DVD and therefore run the Startup
Repair tools like memory diagnostic. If you get
back into Windows, you can then do a system
restore, etc.
– A few people have also had success by
resetting their BIOS. You can reset the BIOS by
clearing out the CMOS. You can clear out the
CMOS in several ways including pressing a
button on your motherboard, changing a jumper
setting, etc. You will need to perform a Google
search for your particular machine to find out
how to clear the CMOS.
– If you’re still going strong and trying to solve
this issue, you can really put your tech skills to
use by trying to replace the classpnp.sys file
with a copy from another computer. The location
of the file is C:\Windows\system32\classpnp.sys.
Of course, Windows won’t load, so you can only
do this using a Linux, like an Ubuntu Live CD.
You’ll have to Google how to copy files using
this, but it’s really not too bad. It has worked
for several people, so it’s worth a shot.
As a last resort, you can try using some spare
parts if you have any and replace as much as
you can: graphics card, sound card, hard drive,
etc.
Windows 7 Hangs at Shutdown
If you’re having issues with Windows 7 hanging
up while shutting down, then you’re luckier than
the previous set of campers. That’s because you
can at least get into Windows and normally it’s
only a software/program issue in which Windows
is not able to unload or kill a certain process,
etc. That’s much easier to deal with than
messing around with hardware, the BIOS, and all
kinds of crazy repair tools.
Note that the first thing to try is to restart the
computer in Safe Mode and then perform a
shutdown. If the computer hangs while shutting
down in Safe Mode, it could be a hardware
issue. If it restarts fine, then it’s probably a
software issue related to Windows when it loads
all the normal drivers and processes.
Here are a couple of things you can try, which
should solve your problem eventually:
– Go ahead and install the latest Windows
updates. There are a few hotfixes that Microsoft
has released that pertain to this exact issue and
therefore could solve your problem without you
having to do anything.
– Next up is hardware attached to your
computer. Unplug all USB devices, network cords,
firewire, HDMI, etc and then try to do a restart.
If you’re lucky, it could be as simple as that.
– Also, it’s best to update all the drivers for any
hardware on your computer including network
cards, graphics cards, sound cards, card readers,
etc, especially if you’re running Windows 7 64-
bit. If you don’t have a compatible driver
installed, it can cause the shutdown problem.
– After that, check out the software on your
computer. If you’re running 64-bit Windows, you
need to uninstall any third party apps that
could be causing conflicts. One client had 7-zip
installed and it was causing Windows 7 to hang
on shutdown. Another client was using the Sticky
Notes app that Microsoft wrote! After putting a
note on his desktop, the computer started
hanging. Removing the note and the app fixed
the problem. It’s best to check any freeware
apps you may have downloaded and try
uninstalling them. Other programs include anti-
spyware apps or anti-virus apps, which could
definitely cause this type of problem.
– In addition to third-party apps, disable any
extra programs that may be running in the
taskbar, such as graphics card monitoring
software or printer management software. HP has
some crappy printer monitoring programs that
you don’t need and can cause issues with
shutting down. People have also reported
NVIDIA software to cause issues. You can disable
all these apps quickly by going to MSCONFIG and
then click on Startup Items. Disable all startup
items and see if your problem goes away. If it
does, then re-enable items one by one until you
find the problem startup item.
– If you’re still having issues, it could be a
problem with a Windows service. This is a bit
trickier because it’s hard to figure out which
service could be causing the problem. The best
way to see if it’s a service problem is to go to
MSCONFIG, click on Services, check the box to
hide all Microsoft services and then uncheck
everything that is left over. Those are all third-
party services. You will have to kill the computer
after doing this, but all the services should be
stopped when you log back into Windows. Then
try to shutdown like normal and see if you are
able to do so. Then manually enable one service
at a time until you find the culprit.
If you follow the steps mentioned above
thoroughly, you will be able to fix this problem.
If you can’t or if you need some more help with
certain instructions, then post a comment here
