I had this issue for the second time within the space of one week. I start up my PC which powers on for a few seconds then turns off. When it succeeds in powering up I am led to a screen saying 'overclocking failed!' I enter the BIOS and click on a 'use default settings' option and continue to windows with no further error.
I would like to try and prevent this from happening again, and to understand what the error actually is. I know nothing about computer hardware.
I will add below some PC specs below, please let me know if you want additional details.
Windows 10 Pro 64-bit
Intel Core i5-2500K
GTX Titan Black
I should mention this PC is second-hand, built by a friend. I have not tinkered with it in anyway myself. I am waiting to hear back from him as to whether he ever had this issue but I doubt it as I have owned it now for several months without this error occurring.
Many thanks for any assistance.
