Most people may try a few easy troubleshooting options, but they ultimately become frustrated after a few minutes. But the true PC problem solvers are a more stubborn breed. Weíll stick with a problem for E hours until our system is running smoothly once again. But between swapping components and taking time to figure out POST error codes, even a few hours might not be enough time to solve your troubleshooting issues.
