Ultimate troubleshooting guide for Windows 7 Pending issues

Previously, I wrote the definitive Troubleshooting Guide for group problems in the Windows 7 home, which many people considered useful. Today, I am going to write a definitive troubleshooting guide for the outstanding problems of Windows 7. This includes Windows 7 that hangs on startup / crashes, which hangs at the close of the session, hangs when it shuts down, that crashes. hangs when installing programs, etc.

Although Windows 7 is a big step forward in Windows Vista, it still has many problems. I have had numerous problems with blocking Windows 7 when performing routine tasks on my computer. I have tried to collect so many solutions that I ended up using in this guide. Hopefully, someone can solve your problem by looking here instead of searching a lot of websites.

Try to make the guide more navigable by using section headers to identify what kind of hanger I am trying to deal with. That way, you can simply jump to the part that you think might address your problem. Feel free to comment with solutions / questions!

Hanging while on Windows 7

If you have already logged in to Windows and have problems with blocking Windows 7 when opening programs or clicking on dialog boxes or clicking with the right button, etc., you should try the following procedures. Usually, this means that there is some software installed on the computer that is causing problems with other aspects of Windows. It could be antivirus software or just a normal program that you download from the Internet. Either way, the best way to see if this is really the problem is to make a clean start.

Step 1: Log in to Windows 7 with administrator rights, click on the Start button and type MSCONFIG in the search box.

Step 2: Click on the General tab and choose Selective start . Be sure to uncheck the box that says " Load startup items ".

Now click on the tab Services and check the box that says " Hide all Microsoft services ". Then click on the button Deactivate all .

Click OK and then restart your computer. If you discover that Windows no longer hangs, you can be 100% sure that it is a problem with a third-party program or service. There is no easy way to determine what startup item or service is causing the problem. Basically, you have to solve it manually by re-enabling half of the startup items and then restarting. If the problem comes back, you know that the problem element is in that list of marked elements. Then you check half of those and restart again. You will have to do the same procedure with the services if it is not a startup element that causes the problem. Eventually, it will only have a marked element and that will cause it to hang.

Once you know what program it is, go ahead and unzip it. Uninstalling the program also disables the services associated with that program. Then, you can return to the MSCONFIG utility and select Normal Start.

Windows 7 crashes at startup – Classpnp.sys

One of the most unpleasant blocking problems in Windows 7 is when it hangs during startup on the "Starting Windows" screen. I have seen this problem with many clients and it can be a real pain because many of the recommended fixes (by repairing the system or restoring the system) do not work.

If you try to run Windows 7 in Safe Mode, it fails in Classpnp.sys. What we discovered was that this problem could be related to a couple of things. The first thing you should try is the startup repair or system restore using the DVD. You can read online how to boot from DVD and access these options. There are a lot of guides out there, so don't repeat that information. Just be sure to enter the BIOS and configure the Boot from CD / DVD as the first priority over the Hard Disk.

If that doesn't work, try restarting Windows in debug mode. You can restart the computer and press F8 to get a list of startup options, including Safe Mode, last known valid configuration, etc. Sometimes, Windows loads in debug mode and can then restart the computer and start in normal mode fine.

Now, the real problem arises with people trying to use the DVD and hangs on "upload files", which means that you will never be able to access system repair or restore options. That usually means that it is a hardware problem. Some people got stuck in the classpnp.sys part after performing a Windows update, which means it could be related to the software.

– In this case, you can test the last known valid configuration or try to start in safe mode and then uninstall any Windows update by going to the Control Panel – Programs dialog box. If you can enter Safe Mode, you can also try to run chkdsk, sfc / scannow or try a system restore.

– If it is related to the hardware, you should examine the antiquity of your hardware and if something could have failed. For example, an incorrect memory slot can cause this problem. Remove one memory chip at a time and see if the problem goes away. Make sure that the memory is correctly inserted in the slot. Many times, memory is not inserted completely and causes all kinds of crazy problems. Also, try replacing memory chips and see if that works. The amount of chips that go wrong is incredible.

– If you have this problem on a desktop computer, you must open it and make sure that all cables and all cards are plugged correctly into their respective slots. Be sure to check the power supply and make sure that the motherboard power is fine. If there is a lot of dust in the system, use some compressed air and clean it well. This may seem a bit too much, but if you can't even start the DVD without crashing, you have a hardware problem, not a software problem.

– Then, you must enter the BIOS and disable all hardware, including USB ports, sound card, floppy disk, 1394, media card, network card, etc. Try using the internal / integrated graphics card instead of the dedicated card. If you can't disable something, try disconnecting it. For example, if you have a DVD drive (s), continent and disconnect it from the system internally. I had a client whose DVD drive was causing the system to crash. Try to start now and see if you can pass the hung screen. If so, then it is definitely a piece of hardware that causes the problem.

– Another piece of hardware to verify is a multi-slot USB card reader. If you have it connected to your computer during startup, sometimes you can try to use it as a boot device and fail. Continent and disconnect all peripherals connected to the computer.

– If you are using any type of KVM switch for multiple keyboards / mice, then go ahead, unplug it and connect a PS2 mouse / keyboard to your computer. Many of these KVM switches use USB and, for some strange reason, can cause problems with the boot process on certain machines.

– In addition, others have succeeded in changing the configuration of the hard disk drive related to ACPI . Try to enable and disable this function and try to restart your computer. There are a lot of settings in the BIOS and you can try to go one by one and change one setting, restart and, if it doesn't work, change it again and change a different setting. It is impossible to say what configuration in the BIOS can cause the system to crash, but a good number of people have succeeded in changing the configuration there.

– Speaking of hard drives, you can also check if the configuration of your hard drive 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, such as the memory diagnostic. If you return to Windows, you can do a system restore, etc.

– Some people have also succeeded in resetting their BIOS. You can reset the BIOS by deleting the CMOS. You can clear the CMOS in several ways, including pressing a button on your motherboard, changing the configuration of a bridge, etc. You should perform a Google search for your particular machine to discover how to clear the CMOS.

– If you still go strong and try to solve this problem, you can really put your technical skills into practice by trying to replace the classpnp.sys file with a copy of another computer. The location of the file is C: Windows system32 classpnp.sys. Of course, Windows does not load, so you can only do it using Linux, such as an Ubuntu Live CD. You will have to search Google for how to copy files using this, but it's really not that bad. It has worked for several people, so it is worth a try.

As a last resort, you can try using some spare parts if you have any and replace as much as possible: graphics card, sound card, hard drive, etc.

Windows 7 crashes when shutting down

If you have problems with Windows 7 hanging while turning off, then you are luckier than the previous set of campers. This is because you can at least enter Windows and, normally, it is only a software / program problem in which Windows cannot download or delete a particular process, etc. It is much easier to deal with that with hardware, BIOS and all kinds of crazy repair tools.

Keep in mind that the first thing you should try is to restart the computer in Safe Mode and then shut down. If the computer hangs while shutting down in Safe Mode, it could be a hardware problem. If it restarts well, then it is likely to be a Windows-related software problem when loading all normal drivers and processes.

Here are a couple of things you can try, which should eventually solve your problem:

– Go ahead and install the latest Windows updates. Microsoft has published some revisions that refer to this exact problem and, therefore, will be able to solve your problem without you having to do anything.

– The following is the hardware connected to your computer. Unplug all USB devices, network cables, firewire, HDMI, etc. and then try restarting. If you're lucky, it could be as simple as that.

– In addition, it is better to update all drivers for any hardware on your computer, including network cards, graphics cards, sound cards, card readers, etc., especially if you are running Windows 7 64-bit. If you do not have a compatible driver installed, it may cause the power off problem.

– After that, check the software on your computer. If you are running 64-bit Windows, you must uninstall any third-party application that may be causing conflicts. A client had 7-zip installed and caused Windows 7 to crash on shutdown. Another client was using the Sticky Notes application that Microsoft wrote! After putting a note on his desk, the computer began to hang. Deleting the note and the application solved the problem. It is better to review any free software application you have downloaded and try to uninstall it. Other programs include anti-spyware applications or antivirus applications, which can definitely cause this type of problem.

– In addition to third-party applications, disable any additional programs that may be running on the taskbar, such as the graphics card monitoring software or the printer management software. HP has some crap printer monitoring programs that you don't need and can cause problems with shutting down. People have also reported that NVIDIA software causes problems. You can disable all these applications quickly by going to MSCONFIG and then clicking on Startup Items. Disable all startup items and see if your problem goes away. If you do, re-enable the items one by one until you find the problem start item.

– If you still have problems, it could be a problem with a Windows service. This is a bit more complicated because it is difficult to find out what service might be causing the problem. The best way to see if it is a service problem is to go to MSCONFIG, click on Services, check the box to hide all Microsoft services and then uncheck all that is left. Those are all third party services. You will have to kill the computer after doing this, but all services must stop when you log on to Windows again. Then, try to shut down as usual and see if you can do it. Then, manually enable one service at a time until you find the culprit.
