    More likely it is heat issues or some other component failing. Power supply, RAM, motherboard are the most likely culprits.

    You should observe the crashes more closely.. Do they happen when you are doing something specific? Is the computer under heavy load or has it been running for some time when it dies? It the machine getting hotter than usual? Any unusual sounds? Do you see anything in the Windows event log?
