I just build my game PC, but what a disappointment , faced a lot of problems:
1- random blue screen (some thing about dumping physical memory).
2- when installing games a lot of files failed to copy.
3- the time keeps changing randomly.
1: You need to see what the actual error is. Every blue screen will dump the physical memory so that isn't helpful.
2: Sounds like a problem with the hard drive.
3: Sounds like a problem with the mobo battery.
