Until today my PC has been functioning mostly regularly. I had to replace the PSU sometime back when I upgraded my GFX card. I know my system is aging and sooner than later will need to build a new system as this one was built in 2012. But in the mean time an issue has cropped up with this one. The system won't post with the RAM configured to it's specs of 10-12-12-31 DDR2400 and voltage set to 0.1v higher than spec because for some reason that I can remember. It will post and run fine now if I reset the BIOS and keep the RAM default settings 9-9-9-24 DDR1333. At this time I have not tried any other settings as I wanted to post this first for advice on how to proceed. It's been so long since I have had to do anything that I don't even know if the testing software I used 2012 and back are still relevant or if there are new preferred stuff. Thanks.
