So I was installing Kaspersky on a client's computer when it froze up. So I restarted it and then windows said it had to repair. So I clicked that and then it said it cannot repair whatever happened. What happened and why? I did buy ddr3-2400 ram cause the MB said it could handle it. When I got home I realized the cpu (i3-4170) said that nothing over ddr3-1600 would work. Well when I installed it and got the pc up and runnin everything worked fine and continued to work fine until today. I asked in a thread on this site if that memory would be ok and you guys said it would be fine and not to worry bout it. Could the memory be the problem? I'm reinstalling now and hope all is well.
