Unbelievably slow speed to turn on and re-open

Hi there. I bought this refurbished from an online company. Ever since the first week or so it's been unbelievably slow. It takes an age to turn on and then when the desktop has loaded it can take something 5 mins+ just to open a browser or any apps. Sometimes it then works fine, but sometimes even just switching between apps or tabs on a browser can take forever. I don't have loads of apps or tabs open, hardly anything saved on the laptop and only a handful of apps. It's 8GB RAM and core 1.5 8th gen so nothing obvious for it to not be working well. Any ideas would be super appreciated! Thanks, Tim

Hi @timothyreynard

Try the following and check if any resolves the problem.

a). Turn on the laptop and when it starts to boot into Windows, force stop the laptop by pressing and holding the Power button until it turns off, then release the button.

Do this 3 times in a row i.e. turn on > start to boot into Windows > force stop > turn on > start to boot into Windows > force stop > turn on > start to boot into Windows > force stop.

On the 3rd attempt it should boot into the WRE menus (Windows Recovery Environment).

Once there, select Troubleshooting > Advanced > Startup repair and follow the prompts. Do not select Reset this PC because if you select the wrong option after this all your data may be erased as Windows will be reinstalled.

b). Start the laptop and on the Windows desktop, type cmd in the search box on the Taskbar. Select the Command Prompt > Run as Administrator option.

In the Command window type sfc /scannow, then press the Enter key. This is old time computing as the mouse doesn't work in a Command window. If you make a typing error use the backspace key to delete back to the typing error and re-enter the command. Yes there is a space between the sfc and the / characters but not between the / and scannow characters.

c). Check how long it takes to start in safe mode with networking.

If it is a lot quicker then there may be a driver problem. Only generic Windows drivers are loaded in safe mode and not hardware specific ones

Have you checked that all the drivers are the latest version?

Check Device Manager for any entries showing a red cross or yellow exclamation mark, showing a problem with some hardware in the laptop. To get to Device Manager in Win10/11 press the Win key + x key (both together) and click on the Device Manager link.

d). Check in Event Viewer for any Critical, Error and Warning events that show multiple listings. If there are any search online using the Event ID and Source information to find out what it means. To get to Event Viewer in Win10/11 press the Win key + x key (both together) and click on the Event Viewer link.

Report back with what you find if you need more help.
