Well,I really need help.I was opening a 1080p video,when I had been copying a file,and my system got restarted,saying a Blue Screen Error.
I have a AMD Sempron 145 CPU,Asus M5a78-m lx v2 motherboard,2 GB DDR3 Ram,250 GB WD HDD.
This error has occured many times.So I'm really confused about what is happening.I have just bought the system,which is about 4 months old....
Pls help me.Thanks in advance.
