I recently assembled a new computer, and today, tried to install Windows 8. It went through all of the steps, and then installed devices. Finally, the screen went to this: http://i.imgur.com/llICq.png . While on that screen, my computer completely turned off. I tried again, and saw that the previous hard drive partition made during the first install attempt was still there. I tried to make a new partition, and went through the installation process again, but got the same ending.
Here is the relevant part of my build in case it might be of help:
Optical Drive: ony Optiarc 24X DVD Burner, Bulk Package 24X DVD+R 8X DVD+RW 12X DVD+R DL 24X DVD-R 6X DVD-RW 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM Black SATA Model AD-7280S-0B
HDD: Seagate Barracuda ST1000DM003 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive
Memory: Crucial Ballistix Sport 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model
I was having this issue, but after I logged in and updating my graphics driver. Try using MoBo Chipset just for install.
Thanks, that's helped narrow down the problem...I was already using the motherboard graphics, so I borrowed a graphics card from another computer and it worked fine. I've now found that the problem only happens when I'm using the onboard HDMI connection - onboard VGA is fine, as is dedicated graphics.
Unfortunately it still happens within Windows now that I've got it installed (not often, but there must be something triggering it)...does this look like a faulty motherboard, given that onboard VGA is OK, but HDMI isn't??
Windows Event Log doesn't give many clues, just a Kernel Power error
Thats what it seems. When my old old old MoBo went in 1 of my first PC builds, the computer would turn on and I would just have a black screen.
If I were you, I'd test every component of your PC, Ram, HD's, Drives. Check out google for some diff ways of troubleshooting them. Only reason I suggest that, is because it would really suck to go and replace the whole machine for guessing the wrong part.
