This is an Asus S56C notebook running windows 8.0 For about 3 months now it's had a problem that it takes several minutes before the initial bios screen appears, and then it stays on that screen before windows starts to boot. Once it boots it works absolutely fine.
I've flashed the latest bios into it. This made no difference. Has anyone got any suggestions as to what the problem might be?
Edit: Actually, i'm not convinced that i'm correctly interpretting what i'm seeing. I said it takes several minutes before the bios screen appears. I said this because this is a screen which says 'Asus' across the middle of it. But actually now i'm thinking that this is part of the Windows 8 boot up sequence. But for sure, we are seeing a completely black screen for several minutes, If I press the F2 key during this time, I eventually get into the Bios screen. I've tried disabling hardware in there, and applying Optimal and Setup defaults. All to no avail.
