I've recently been having a lot of trouble with my pc, I built it myself about three to four years ago and for the first two years it ran very smoothly. I had spent a lot of time and money into it and was very proud of what I had made. Since installing windows 10 about a year and a half ago I ran into some issues, I would consistently get a BSOD and at the time did not know what was causing my problems. As a typical teenage boy, i let the problem drag out without trying to find a solution for it, I would pray for lucky days and then play video games for as long as I could hoping that it wouldn't crash. After reaching a point where my PC just wouldn't run 5 mins without crashing I resorted to sending it to a local expert to take a look but they couldn't find my problem. I would then spend hours looking for problems and even resorting to just resetting my system. After a few months with no success, I decided to upgrade some parts assuming it was a hardware problem. I bought a new CPU and a new Motherboard. As I say I was a teenage boy that makes rash and impulsive decisions. After trying these new parts out I came to a conclusion that my PC was finished and left it for about a year without going on it as I couldn't handle the stress. Tomorrow I leave for University and over the last couple days I have been trying to fix my PC once again as I would really like to take it with me, I am also studying a course that will require a computer that can run some heavy programs (ngl I also would like a game of LoL once in a while). I downloaded a blue screen viewer program and received information back that said I had an error code 119, after research, I assumed this was a graphic design program. First, off I ask for anyone who may have the knowledge of PC hardware that first with these issues is it safe to just upgrade parts? I was thinking of upgrading my graphics card next purely to see if that's the issue with it being a few years old now (Its the Asus GTX 660) whereas id consider my motherboard and CPU to be fairly new. And second, I ask would you say at this point its legit worth buying a whole new system, maybe keeping some of my newer parts and going from there. I have been told that even my windows could be a problem. After suffering for so long with so much help, all i ask for is a little guidance from anyone who may be able to give it. I also do not know the exact specs of all of my components but I know I'm running 8GB of memory, I7 intel processor and i have an SSD as well as a WD Harddrive. As I say, any little helps such as any good for value graphics card suggestions or even if it's just a funny joke to cheer me up. Thanks.
