I've recently started having issues with my pc just randomly freezing. Mouse becomes unresponsive and can't ctrl+alt+del, I have to force a shutdown each time. I did upgrade my ram recently from Corsair Vengeance Pro 8 GB (2 x 4 GB) DDR3-1600 Memory to G.Skill Ripjaws X Series 16 GB (2 x 8 GB) DDR3-1866 Memory. I'm assuming it has something to do with that as nothing else has changed recently. I don't have a profile in my bios for 1866 as I don't believe my MOBO (ASRock H97M PRO4 Micro ATX LGA1150) supports it so I have it set at 1600, there is no XMP profile. I've also tried changing that to 1333 but it still freezes. I just ran memtest86+ and it found no errors so I'm not sure what to do next.
My only guess is an incompatibility between the motherboard and new ram however according to PCPartPicker they are compatible. Maybe I should check to see if my bios needs updating. Thanks in advance!
