My Gateway PC Tower went on the blink, I am using an older PC Tower (Windows 98 System) while the other is being serviced. The older one will boot up, slowly, upon accessing the internet or other areas, it will freeze up then shut down automatically, what should I do? Let me add, until my previous PC Tower is serviced and that matter is resolved, it is of some urgency that this temporary PC tower be resolved if there is a simple "fix" to the problem. Thanks in advance for any solutions or suggestions.
