Hello everyone,
I came cross this problem last week and since then, i did a hell search, so its not the boot disk or the boot flash drive, also its not a memory and its not a hard drive, its mot likely an issue with either motherboard or video card, sound funny right? anyways, i just want to tell you how i over come this problem, the windows i was trying to install is a genuine full version of windows 8.1, i took my drive to a different computer and i used that computer to install windows 8.1 64 bit, then i took the hard drive and put it back on the original computer and it works, more information one of the test that i did when i bought the software from best buy which is 8.1 Full version, it came with 2 disks, 1 32bit and second 64bit, so when of the test i have done, its trying the 32 bit, and it works, but because i need it windows 64 so i had to do the above, if you have more question please post your question, thanks
