Not sure if this is the right place to ask, but... my PSU is 6 and a half years old. Recently I have been having random full system crashes when playing video games. As far as I can tell, this is not an overheating problem. So, I'm wondering if the PSU is failing. I am not really experienced with diagnosing hardware problems or know how to read much of the info in HWiNFO. Am I supposed to look at the voltage numbers under the motherboard section to determine if the PSU is working correctly? Also is it possible that a bad HDD could cause these crashes? The S.M.A.R.T section shows a drive warning for my HDD (however my OS is on a separate, healthy SSD).
