After a year of getting blue screens and having multiple problems the computer is now in need of serious help. Recently every time I got a blue screen i would hit the back of the computer where the graphics card is located and it would boot back up. One day the computer blue screened as normal and the computer would not turn back on. I removed the graphics card and the system booted up using the motherboard graphics. I am pretty sure that the problem is that the computer needs a new graphics card but I dont want to spend 300$ on the wrong part. Any suggestions/help?
