This is the first time posting on this forum so I'm not sure if I'm posting in the correction section but here goes.
I'm going to start off by saying that I am very disappointed with the Dell XPS L502x that I bought 2.5 years ago which in my opinion not that long for a laptop. I expect a laptop to function fine for about 4 years then start to deteriorate over time. My previous laptop, a Sony Vaio, lasted for more than 5 years and still counting with minor wear damage that is normal for a laptop that was very frequently used. However, this Dell laptop I got only 2.5 years ago are having multiple problems that have yet to be fixed through various means I have tried.
The problems arose about a year ago when I experienced the first of many crashes. It would make a loud buzzing noise (the sounds of the video game I was playing at the time repeating or stuttering) and my computer would lock up preventing me from doing anything on the laptop. Sometimes this would cause a BSOD but other times it would just freeze forever and I would have to force shut down by holding the power button. Now this problem is occurring more and more frequently and now it won't even BSOD but just freeze and my computer and make the loud noises.
I have tried updating all the drivers including video card drivers to the most current ones, updating the BIOS, taking the computer to the shop to get the dust out from the fans, diagnosing it for problems in the hardware, undervolting the BIOS so the video card wouldn't overheat but nothing worked. Now over a year has gone by with this problem and not being able to fix it by all the ways I have researched and tried. I am fed up with this and need fixes, more suggestions, or answers to the problems my laptop is having.
