I am getting a "tablet" Error message everytime i Restart or shutdown my computer. It says something about 0x0012e818 and "memory could not be written"
Also i have got a black screen with "No OS found" Insert Start up disk and hit enter error message on start up. I have an External Seagate Hard Drive connected and have noticed that if i turn the power off on that when i am booting I don't get that message.
I am not good at this sort of thing. Any help would be great.
