Just recently my laptop monitor has been displaying random green dots/pixels on my monitor, it has happened one time before a few weeks ago, but I turned off my computer and it worked normally again. However today i woke my computer from sleep mode and the green dots appeared again, but this time I have shut my laptop down a few times and the green dots appear every time I start it back up. I have been searching Google and everybody has different suggestions to fix this issue and different reasons to why it is happening exactly.
I would also like to note that my computer overheats frequently, it may or may not have something to do with the problem
My laptop is a refurbished HP Pavilion DV7 from 2010. There is no overclocking or any hardware adjustments to my knowledge
