Have you checked the cpu fan for fluff etc ?

The HP laptops of that vintage are well known for their poorly
engineered cooling systems. Not only can the CPU overheat but the GPU
will also overheat. This will cause all sorts of video issues. Open the
laptop and thoroughly clean out the accumulated dust in the heat sinks,
vents and fans. There are all sorts of youtube videos to walk you
through the procedure. If you repair it before the video chip gets
cooked, it should last a long time. A bit of advice regarding the
youtube videos that demonstrate how to re-flow the solder on a failing
video processor, it's only a temporary fix and not worth the trouble.

Apple sold Macbook Pro's around 2010 made with a new soldering
profile/process that caused the GPU balls to crack. Eventually they were
persuaded (by a class action) to replace any that were returned, even
outside the warranty period - but the replacement logic boards had the
same fault and failed again within a year. Ask me how I know

After over a decade of using Apple hardware, I am now determined that my
next computer will *not* be an Apple.
