  1. Hello I have a problem with my PC that i built a year ago. The problem has always been there, it's just never been a problem up until now that I have gotten into overclocking. The problem is that my PC will not boot up past the asus splash screen if I have not switched off the power supply switch after turning off my PC. It will get stuck at the splash screen telling me to press delete if i want to enter the BIOS. Nothing happens when i press delete or anything else and I am forced to press the power button to turn off my PC. If i switch it back on the PC boots completely without problems and i can go into the BIOS by pressing delete if i wish. At some random times the pc will actually boot without me switching the PSU off and on, but when i get to the login screen my mouse will not respond and is stuck in the middle of the screen even though I try and replug it in different USB ports. And again, zero problems after switching off the PSU and turning it back on. I have updated the BIOS and done a fresh install of Windows 10. It fixed nothing. The scary part of updating the BIOS was that the problem caused it to never boot correctly as i was supposed to restart the PC after updating. I had to turn it on and off many times before i got any response to the monitor, then finally it updated, but did not fix my problem. I also tried all the options for fast boot on and off. Nothing changes the problem. The reason I want to fix this problem now is because i want to overclock my 8700K as i have more than enough cooling to make it run stable at high clock speeds. The problem here is that i cannot make changes in the BIOS that requires the PC to restart completely as it will not boot. I turn it off and on again and I am greeted with the POSTed screen telling me that the previous BIOS settings has been restored either because of system instability or the fact that I had to hold down the power button. (Which i must when the pc won't boot) I can however make other changes in BIOS that lets the PC boot fine after changes as it does not need to properly restart. The fans keep spinning and no lights turn off and my PC is working fine after that boot. I did clock the CPU to 4.7 GHz as i can do that without changing the voltage, but any higher it will become unstable and i have to up the voltage which makes my pc do a proper restart and not booting. I believe the problems have to do with either my boot drive (120GB Kingston SSD) or my power supply (Corsair RM750x 750W). Please, any help is much appreciated. One of the reasons I believe it is the PSU is that when shutting down my PC and not switching the switch to 0 on the PSU, I can hear coil whine or if it is still sending electricity incorrectly and causing it to fail the bootup and therefore works if i turn it off and on, or maybe that has nothing to do with it? Please help.
