and i used a very old WD hdd 500gb with Windows 7 and my system worked flawlessly without a single problem
But sadly my hdd died so i decided to buy WD hdd 1tb black and install windows 8.1
Yesterday the hdd came and I installed the windows without any problems, i left it all night for updates and some games to install and later this afternoon i shut it down completely for the first time.
Sometime later I turned on my pc again and this is where all my problems began:
My pc turned on for about 3 seconds then shut off then turned on again and shut off again, this happened for about 4 times and then managed to boot with a message MAIN BOOT CORRUPTED and started loading a backup boot and all worked perfectly, but now every time i shutdown my computer the same thing happens all the time. I removed the battery so cmos can reset, but it didn't fix a thing.
Do anyone know what may cause this?
(Sorry for my english)
I did as you said, I reinstalled windows and it was ok, but later I installed intel drivers and I had that problem again, after some searching I found that the problem was intel graphics driver, I uninstalled this driver and now my computer runs normally
Thanks for your opinion, it was not a motherboard problem as I was fearing
