Maybe check the BIOs and see what voltage it runs them at stock. You are saying its running stock, but is it running stock cuz you haven't changed it, or running stock cuz you changed BIOS to stock voltage?
Other thing I was wondering is how is it failing. Failure to pos/boot, or BSOD? Good luck tho
