First, the basics: Motherboard: Gigabyte X58A-UD3R (BIOS FH) CPU: Intel i7 980X (not overclocked) Video Card: GeForce GTX 580 running driver 306.97 (latest) Memory: 6 x 4gigs Corsair (CMZ8GX3M2A1600C9) Windows 7 Pro 64 SP1 My computer has been running fine for 2 years and all of a sudden I'm having a lot of random problems which may or may not be related. Of course, nothing definitive has come up which is why I'm here. 1) 5 days ago my computer froze, screen went black, and there was a loud grinding sounding coming from the computer. I restarted and inspected all the fans, especially the PSU, but everything went back to normal. Also monitored temperatures with no issues 2) Starting today I'm noticing all sorts of keyboard and mouse issues. I'm seeing intermittent input lag on the mouse where if I move it in circles it stutters and freezes in place randomly. My keyboard is sometimes outputting information when I'm not typing like "ddddddddddddddddddd" or alt-tabing dozens of times. The mouse issues are more common than the keyboard, but both come and go randomly. As I'm typing this neither are displaying the issue. 3) I've had 2 BSODs today, both which reported almost no useful information with codes: 0x0000001e (0x0000000000000000, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000). Could this be a dying motherboard? I haven't done much software installation lately, so I don't know what could be causing it all of a sudden. I'm not sure if the crash a couple of days ago is actually related, as it worked fine for 4 days before displaying problems today. Without anything definitive I'm at a loss as to what to try next.
