since loading Q/B computer has slowed down, not just in quick books
I'm here to provide some troubleshooting steps to help you resolve the performance of your QuickBooks Desktop and computer.
First, you'll want to check the system requirements for QuickBooks Desktop. Its performance is based on how much system memory (RAM) you have on the computer. It usually requires a minimum of 4.0GB RAM. Check out this article for more information: QuickBooks Desktop system requirements.
Next, there may be some conflicting programs that are running alongside QuickBooks causing performance degradation.
Some antivirus security programs can cause performance issues. You can temporarily disable it to see if performance improves.
On the server computer, disable the anti-virus security software.
Open QuickBooks. See if the performance has improved.
If the performance is the same, proceed below to check for third-party programs conflicting with performance.
If the performance is better while the antivirus program is disabled, set exceptions to allow your security program to bypass QuickBooks.
Note: Make sure to turn your antivirus back on after testing performance.
Running some third-party background applications can cause performance issues with QuickBooks. An easy way to diagnose if this is the cause or not is to use Selective Startup. This will only load the basic drivers and startup items required to use your computer.
Press the Windows key+R on your keyboard to open the Run command. Type msconfig, then press Enter.
Select Diagnostic Startup, then press OK.
Reboot your computer. Test the performance of QuickBooks.
If the performance is the same, proceed to the next solution.
If the performance is better while in Selective Startup, it is recommended you work with your IT professional to determine which specific program is causing the performance issues.
Once you have finished testing the performance in Selective Startup, follow these steps to get back to normal operation:
Press the Windows key+R on your keyboard to open the Run command. Type msconfig and press Enter.
Select Normal Startup, then press OK.
Reboot your computer.
