Hi. My current pc has stopped producing a video output after post. This occurred after testing a friend's SSD in my computer to confirm if it was dead. My computer now turns on. Passes post and then just goes to a blank screen and stays there. I have no idea what is causing this as I have already tried several things. All of the below result in the same blank screen: Removing all but 1 ram stick. Disconnecting unneeded drives. Disconnecting unseeded usb devices. Cmos reset. Attempting to boot from my windows 7 disk. My system specs are: MSI p45 mobo Q6600 6gb ram Gtx 560ti Hitachi 160gb boot drive Hitachi 1tb drive I was currently running the windows 8 consumer preview. Any suggestions are very welcome. Thanks.
