CPU Is Unstable Problem Solution

CPUs rarely “go bad.” They typically work or don’t work. Usually, it’s everything around them that breaks. If you’re overclocking, stop. Try to isolate CPU problems by running a CPU-intensive app such as Prime95. If it blue-screens, check thermal issues first (see “CPU Is Overheating”). Also check your RAM with Memtest86+ (www.memtest.org).
Check your power supply connectors to the mobo and GPU. If the PSU is overheating and failing, it could cause crashes. Failing PSUs cause power sags, which can look like a bad CPU, too. If you have a known good PSU you can swap in, do so. Oddly enough, a failing GPU can resemble a CPU failure, so if you have a spare GPU or an integrated option, try switching to it and testing again.
