Reboot issue - help to diagnose please

[tophee]

Hi,
My pc has an irritating habit of rebooting itself on start up.

I've checked the connections, though I will do again (more thoroughly later when I've finished doing the work I'm currently doing). But I'm a bit perplexed to why it's doing what it's doing.

I press the power button, and the pc posts, shows the BIOS flash screen and gets to Windows login screen then restarts. Once it has rebooted again, it's all fine and works well. No issues with any processor intensive programs or anything. Games seem to run with no issues, I can virtualise other OS's fine. Not overclocking currently. All setting in BIOS are stock I think, - apart from turning on the virtualisation optimisations.

Running Windows 8 64bit release preview

My hardware is:
Intel i7-3770K
Asus P8 Z77-V LX
16Gb Samsung Green ram DDR3 PC3-12800 (2x8GB kits)
Nvidia 460GTX
Samsung 250gb 830 series SSD
500Gb SATA3 western digital drive
40Gb SATA2 OC vetex SSD drive (as photoshop scratch drive)
1Tb Samsung drive
Corsair TX 750W PSU

Thanks

This used to work on previous asus motherboards.

In BIOS change settings to XMP instead of auto.
Check BLCK to 100MHz (may be different now for ivybridge)

Also check memory one stick at a time in different slots and run memtest.

Or set your ram manually. XMP on my board tends to set the ram at 1333mhz and max voltage 1.65v. So i don`t use it.

Ok, I'll check those settings. Thanks
