I just got a new Sandy Bridge Motherboard/CPU with new DDR3 RAM. It's currently running through the latest Memtest beta build. (Tip for any other sandy bridge adopters running Memtest: Anything but the latest version will hang. It's not because your new build is bad, it's just incompatibility. So before you freak out, make sure you have the very latest beta from here - there's an .iso too if you scroll down.) All seems well on the memtest front so far.
However, I've already noticed some strange behavior regarding booting and rebooting. First, when I press the reset button, it seems to power off entirely - fans stop spinning, LEDs turn off - for a good second or so before turning back on. Perhaps this is normal for the particular board, but I can't recall having another computer that responded to the reset button like this.
More worrying is that sometimes, when it then reboots, it will sometimes do this again - shutting down for a second or two and then booting back up - after the Gigabyte boot-up screen appears. This has me worried I have a faulty board (or faulty/inadequate power supply).
Gigabyte P67A-UD3 motherboard
Core i5 2500k
8 gigs RAM (2 x 4GB Mushkin 991770)
Corsair VX 550 watt power supply
Radeon HD 4770
I haven't touched any overclocking options. The power supply and Radeon are from my prior computer and worked fine there. I suppose that doesn't get the power supply entirely off the hook as it was a lighter motherboard & CPU, so perhaps the extra power draw is making a difference.
It seems to have stopped doing the double-reboot. Perhaps it had something to do with forcing it to boot in to XP, resulting in the occasional hang.
The power-off delay when hitting the reset button is still the same, but I guess that may just be the way this board is.
Apologies for the premature post. At this point, since I can't reproduce the double-boot, Windows 7 installation is proceeding smoothly, and I'm not getting this upon powering it on, I'm hoping it was a quirk of resetting XP without a proper shutdown.
I'm not sure what you're referring to with Smart6, most of that seems to involve utilities installed after Windows is. Are you suggesting there may be some QuickBoot settings in the BIOS that I could change?
As for Win7 install, I'm aware it does. I was simply testing to see if it would boot into XP as one test to see if the new stuff was functioning all right. Once I decided to go ahead and install Win7, I did indeed use its setup to blow away my old XP partition and format a new one.
