I have isolated the issue to a problem that only occur when the Intel HD graphics drivers are installed. No problems with the windows default VGA drivers but the intel drivers cause a reboot with no warning or BSOD. The reboot usually occurs at teh log in screen, but on a few occasions I have been able to log in only to be rebooted in under 2 minutes.
Have tried about 3 different versions of the driver and the same thing happens with all 3.
Having a very similar issue on a very similar setup:
i5 2500k (so, same Intel HD Graphics 3000)
GSkill 2x4GB 10666CL7D
Crucial SSD C300
My issue is that completely randomly, about once or twice per day, the screen scrambles up and the system freezes. Only way out is a reset. No BSOD or anything in the event viewer. So, sounds like the same issue but maybe my system is just holding out a little longer and not automatically rebooting.
Ran memtest for a few passes, no issues. Updated the bios to F7 (google it... it's not on the Gigabyte page). Didn't help.
The latest thing I've tried is giving the RAM a bit more juice. Sticks are rated 1.5V but I bumped them to 1.56V, stock timings. So far so good... it has lasted through the evening and night, but we'll see what happens.
I hadn't tried isolating the graphics drivers (probably should have, duh), but I'll try that next if the voltage tweak doesn't work!
Good luck! Post back if you get anywhere and I'll do the same. Glad I'm not the only one.
I had issues as well. Lock up when scrolling in any browser. I was able to get a stable system by running on 1 stick of Ram. Updated BIOS to F8 didn't help either. I left BIOS settings at default level. I ran stable for one day and just tossed in 2nd stick in different color slot and have been stable for an hour. But I'm not using the onchip HD 300 Graphics. Maybe I'll try removing ATI 5450 video card tomarrow and see if that works.

I've been up for 24+ hours by disabling the Intel drivers... will continue through the night to confirm. That said, the drivers at this point in the game shouldn't be this bad. I am leaning toward a hardware issue with either the Gigabyte board or the CPU.
I had the same problem. After loading the Graphics Driver the system would hang up at the welcome screen.

OCZ 2x2GB 1600 CL8D Slots 1 & 3

No graphics board
I ran through the situation with Intel. They told me I had a chip with a bad GPU. I replaced the chip and installed the 126.96.36.1996 driver from Intel (NOT Gigabyte.) The machine hung on the welcome screen. I don't have a password set up yet specifically for situations like this. I said screw it, let it hang. After about 15 minutes at least, I noticed the screen had begun to show a curser. I right clicked on the screen which did not have any icons or toolbars and went into preferences. After I set these, everything started to work. I then restarted the machine and let it run overnight to check for problems. None so far. The only I can say is the OS is very slow to load - on the order of a minute or so when 30 seconds was the previous norm. Also, the GPU probably was not bad. But wait at least 15 - 20 minutes before hitting the reset button.
Had same issue turned out there was a conflict between integrated graphics drivers and intel rapid storage tech. Could not run both. one or the other. This was back in Jan. and since have purchased P67/ and now Z68 so never came up with a solution as I turned in my H67 for the chipset recall. Hope this helps someone at least a little to poss. narrow down. good luck
Bummer that this issues has not been solved yet. I am having the same issue on a new build. I think I need to install the Intel driver in order to utilize sleep mode but I can get a driver that will work. Win 7 64bit, i7 2600k, no video card, 8gb RAM, GB Z68xp ud3 mobo, HDMI hook up to monitor.
Whenever I install the Intel drivers, I restart and get a flickering screen and freeze at Welcome screen. Did anybody figure out how to fix this?
After several late nights of tests, I've narrowed it down. RAM is all good, but more than one stick causes file corruptions and the above-mentioned screen flickers and freezes. Running with one ram stick but would love to use the onboard gpu.
Is there a way to disable the Intel Rapid Storage Tech?
