I upgraded my Motherboard and CPU a couple of hours ago. I reinstalled Windows on my previously used Samsung 830 128GB (I formatted and deleted it before) and sometimes when I just turn on My Computer it makes a Post Beep (one beep) and then restarts itself and other times it boots in to Windows and just randomly freezes and then I have to manually shut it off and turn it back on. I set my SSD to AHCI mode and I am positive I plugged in everything right. Should I try reinstalling windows again? Maybe this time to My HDD? I dont know if when I formatted and deleted my SSD before installing Windows it messed something up? I just spent almost $300 so I'm a little disappointed. Any ideas on what the problem could be? Also I noticed that on the upper right lower left corner there are no screw wholes to where there was standoffs and there was one whole for a screw in the middle but I didnt have a stand off below it so I just left it, dont know if that has to do with anything just thought I would throw that in there. Also my specs are in my signature. Please Help me figure out the problem, I will greatly appreciate it.
