My computer has been giving me problems recently. I have: Z68 mobo i7 2700k 16Gb ram AMD 6950 2Gb 240gb solid state drive various spinning drives I noticed it first a three weeks ago. We had a birthday party for my son. After the party my computer would post, but Windows wasn't loading. I opened up the bios and startup was pointing to the wrong hard drive, and other things weren't right. I figured that somebody just pushed the clear cmos button during the party. People had been admiring my setup, so that seemed like a reasonable possibility. But now I've been having random crashes. The whole system will freeze and become unresponsive. If I'm watching a video, three seconds of the video will repeat over and over. There's nothing I can do but turn off the power by holding the power button or flipping the switch on the PSU. The startup issues have also been on and off. Sometimes it just takes two or three tries to get it to start and then it runs fine, but there have been increasing instances of the freeze/crashes described above. I've checked the CPU temps, everything is well within normal. I figure the next check would be to replace the battery on the mobo (in case I'm losing power and the battery is dead and that's resetting the cmos) and to test the PSU. I'm not sure what other issue this could be since I've had this computer for years and this is the first time I've had issues like this. Let me know if this sounds like something you've encountered and let me know what steps I should take to fix this.
