How to resolve desktop PC common issues, there are multiple ways to resolve the problems. Here you will see the solution for common problems/errors.





 
 1. Blue screen of death cause
Typically this is occurred by driver or hardware conflict.
Solution: try to look at the dump file to figure out exactly what is the cause of the error. Alternatively update hardware drivers or consider the situation in which blue screen of death happen. For example you've installed new hardware or software also you might want to run hardware diagnostics.   
2. Missing dll files cause


 Typically caused by incomplete software installation
Solution:  reinstall software find the missing dll and copy it to system 32 or while 64 folder registered DLL if needed through command prompt.
Example reg SVR 32 space and then the name of the dll.  
3      3. Software or application will not install
Caused like not enough drive space, newer version already installed, you didn't install prerequisite software. For example vc read dist x64 MS net or direct x or not compatible with the operating system.
Solution: free up space on hard drive, look for previous installation of newer software install and all prerequisites acquire compatible OS.
4    4. Software or OS is running slow cause
 Lack of resources such as RAM CPU or hard drive virus or malware infection missing updates.
 Solution: open task manager and look for RAM or virtual memory allocation any applications use all of the RAM adjust virtual memory if necessary check CPU usage levels, check your hard drive space through task manager, check the system processes and look for sketchy names using a lot of CPU or RAM. Virus can have similar name to common windows components perform full system scan for viruses if you have a virus that you can't remove consider OS reimage or reinstall. Install all updates for your computer. Let them finish reboot updates can take up resources and time as a side note you can also upgrade to SSD storage for a huge boost in OS performance.
5    5. Computer restarting multiple times
In this case software or Windows not updates or a virus
Solution: you have to update the windows. When those updates alone can restart the computer many times and take full scan by updated antivirus.   
^    6. Suddenly applications or computer behaving abnormally
For example software keeps crashing missing files or runs slow cause virus infection or hard drive going bad.
Solution: run virus can check Windows system logs for NTFS system errors or other hard drive related logs. Replace hard drive if necessary. 
7. Internet or website issue error 404 page not found cause
Page is missing or deleted, wrong website link or website is down.
Solution: if specific page is missing search the website for desired content, double check
the website link because it may have been changed if all pages are 404 contact website owner.
8   8. Computer is running hot overheating cause
Poor airflow, not enough system fans, dust or dirt accumulation, CPU fan not working,
CPU heatsink is loose, power supply unit fan is not working, computer case is open, overclocking room or ambient temperature is too high
Solution: add system case fans, clean your computer from dust, if CPU fan is not working replace it,  if CPU heat sink is loose attach it, if power supply unit fan is not working
replace power supply, close the computer case, stop overclocking, move the computer to lower room temperature.
9  9. low memory RAM or hard drive storage cause
Too many programs open such as games, video editing software, and large Excel spreadsheets. See in the task manager hard drive storage.
Solution: close application that use too much RAM and only use one at a time, perform this cleanup to free up space this should you remove recycle bin, download folder cache data temp files, old operating system restore points, alternatively you can purchase more RAM or add a second hard drive.
1  10. Very slow internet cause
Too many downloads at the same time, too many computers sharing internet connection, bad Wi-Fi signal and a virus or malware infection.
Solution: limit downloads, if too many people are sharing Internet you can limit or set
max speed in router for even distribution of bandwidth, check Wi-Fi signal distance and adjust in router, check PC for virus or malware infection, reset router, call internet provider
