Basically, I bought an HP dv7 3178ca laptop about 3 years ago. However, recently (past 6 months) I've had an issue where my laptop randomly blue screens or black screen with a different error everytime. I was sure it was the ram however, when I replaced the ram around (5 months) ago, it just keeps crashing either blue screen or black screen.
I also sent my laptop back to HP where they supposedly cleaned the fan, replaced the thermal compound on the cpu, and replaced the hard drive.
The most odd thing about my laptop however is that if I boot it a couple times run performancetest it will crash a couple times until the point I can boot it and it won't crash at all. I'm not able to reproduce my crashes by doing something and it seems like it will randomly decide to never crash once it gets past the point of crashing a couple times.
At this point in time I'm completely unsure on what to do and how to resolve this issue of intermittent crashing. Is it the hard drive, motherboard and how would I test to ensure it's one of the components for sure before paying to replace it.
Thanks in advance! fox
