    PC suddenly turned off and now only boots if 1 CPU core is enabled

    Yeah I tried but still the same. At least I can run it on the one core until I get a new PC. Is there any possibility that there could be a fault in the power supply and it can't supply enough power to the CPU when all cores are enabled? I'm not getting my hopes up!

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    Not sure if I understood the instructions correctly but here is what I did. I got Linux lite and used Rufus to create the bootable USB stick. I get the initial start-up options but when I launch Linux I just get a blank screen. I also tried Ubuntu and I also get the initial options but after I...

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    You can run faster RAM with the Z170 chipset motherboard. I did not change the RAM, MB, or CPU since the original 2015 build. I have not enabled XMP in the last few years. I did not know you should not boot from USB 3.0. Memtest did the same thing anyway. I tried Windows installation media...

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    Oh sorry it's 2666Mhz. It took a long time for Memtest86 to boot. I got a black screen after the MB logo for many minutes. When I first tried memtest I did not wait that long on a blank screen before I assumed it was not working and turned off or restarted PC. I will try it again in a USB 3...

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    RAM is 1333Mhz. I inserted one stick of RAM into slot 2 and used a regular USB slot on the back ( I was inserting it into a blue USB 3 slot on the front) I have noting in the USB 3 slots now. Memtest did start but it froze after 30 seconds. I tried it 3 times. It also did not run smoothly...

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    I've tried entering Windows Recovery Environment but it does not start. My PC was on high performance mode though, I thought it was on power saving. I've changed it to balanced but I still couldn't enter RE. I have 2 sticks of RAM, I've tried them individually and in different slots. I ran...

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    Yes I did restore to default settings through the BIOS. Sorry for the confusion. I just mentioned the CMOS and the removing of HDDs to show that I did all the usual steps I found online to fix the problem. Disabling the cores was the last thing I tried and just by pure chance. I also did not...

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    Hi, thanks for your reply. I had already tried another GPU and I did set the BIOS back to default settings. I removed the CMOS battery, disconnected all USB devices, all the HDD and SSDs and it still wouldn't boot the Windows installation media from a USB drive. I also could not get into safe...

    PC suddenly turned off and now only boots if 1 CPU core is enabled

    Hi, my PC which I built about 7 years ago suddenly turned off while I was watching YouTube. When it turned back on it said it was "preparing automatic repair" but it kept restarting before it even got to the windows logo. I tried to run Windows installation media from a USB drive but it would...
