Laptop Crashes

[Zeeshan_Asad]

Hello Dear people!
I bought a used pavilion 15 gaming laptop model cx0xxx. The issue I am having is sometimes when the laptop is running it crashes and the screen shows some weird lines and squares. It happens randomly throughout the usage.

Help would be much appreciated. Thank you in advance!

g’day and welcome to the forum.

how long have you had the laptop for?, and how long has this been happening?
where did you get it from?
did it come with any sort of warranty?
maybe this is the reason the previous owner got rid of it???

but being used, the first thing I’d be doing is a clean reinstall of Windows.
I’d want to make sure no previous junk is left behind, no malware, no history, and a fresh install of the latest Windows build and all the drivers was done.

that then would give you a clean foundation to troubleshoot from.
