My mom’s PC has been acting strange lately. At times, when typing several particular keys, gibberish alphanumeric characters show up instead. My husband suspected something amiss last week, suspecting it was due to a faulty keyboard, he replaced it with another keyboard but the problem persists. The funny thing is, sometimes the problem crops up and other times it doesn’t. This is not good. The PC is barely 3 to 4 years old, but I don’t think we’ll be fixing it as it will be difficult to pinpoint where the fault actually lies. It could be the motherboard, system memory or the CPU, you’d never know. So it’s better to just draw up the specs for a new budget PC instead of fixing the old one. Like maintaining old cars, faults will just keep on coming one after another. It’ll be better off just retiring it and setup a new PC that hopefully gives another 3-4 years of trouble-free usage.
