I've had this problem since I bought the computer in Jan. The computer is custom built from a shop I've used before. I've took the computer back to the shop & an independent shop both have said there is no hardware issue. Recently I've also installed Ubuntu which doesn't crash.
The problem is the computer randomly hangs up, I can't do anything, I either have to reset manually or wait a few minutes for the computer to reset itself.
Windows 7 Home Premium 64 bit
Is the original installed OS on the system although I have reinstalled number of times.
Thanks for your help
