I have purchased an OEM pc yesterday and I installed windows 7 x64 on it. Everything went great with installation. No errors or anything. But when i restarted my computer, after the motherboard splashscreen a black screen with a blinking cursor top left appears and windows doesn't boot. But sometimes, especially when i wait a few minutes to turn it on it boots normally till I shut it down. it is so random. What should I do? Please help me because this is driving me insane.
My specs are:
Motherboard: gigabyte 970a d-3
Memory: CORSAIR 4GB VENGEANCE DDR3 1600MHZ CL9(*2)
CPU: AMD phenom ii x6 1100t black edition 3 .3ghz
GPU: Sapphire hd 6870 1GHZ
OS: Windows 7 Ultimate x64
İ have tried all that you said. I even formatted and reinstalled windows. Btw I don't need to boot in safe mode because sometimes it boots normally. Like I said it is so random. For example right now I am playing assassin's creed for hours and it works perrfectly. But if i try to reboot it won't boot. I know because I tried that so many times.
Do you have a spare Hard Drive you could load a basic windows on just to eliminate your current one? Presumably the problem would show itself during setup when restarting...Failing that it is increasingly looking like an intemittent mobo fault, nightmare to find!
Unfortunately i have no other hard disk. But i think it is not windows related because it happens when I try to install windows, the setup restarts the pc and there goes the blank screen again. My entire pc is brand new so does my hdd. Is it possible that my hdd causes these problems? And here is another thing. When I go into repair pc using system disk. I entered the command "Set PROCESSOR_ARCHITECTURE" and it says my architecture is x86. But a x64 windows is installed. Is it an important thing?
Not familiar with that command, is it from the Command prompt? I have a similar rig I'm building to yours with a Phenom II x 6 1055T but an Asus board, if its a DOS command I'll try it to see if it comes up with the same result
Probably for the best,the mere fact it was intermittent would make it next to impossible to fault-find ,especially whne you don't have access to spare mobos and HDDS! Good luck, I'll be interested in the result...
I just built this computer and I have a problem like the OP, a lot if not all the times that I restart or install drivers I get this black screen with blinking cursor. After that happens I alt+ctrl+delete to reset and the Windows Boot Manager Black Screen pops up:
Windows has failed to start, etc etc repair your computer etc.
Info: The boot selection failed because a required device is inaccessible.
So I hit enter and another black screen error message pops up:
Windows Error Recovery
Launch Windows Recovery
Start Windows Normally
I select Launch Windows Recovery and then the Windows Boot Manager Pops up again, I hit enter, Windows Error Recovery screen is back again and I select Start Windows Normally and it works.
My question is how do I fix this so I don't have to do this all the time?
