ok... new one happened today... scarred the crap out of me, cause It made the HD vanish for a good time... (HD wasn't recognized after boot... it simply said that there was no HD)
*photo of error on attachment*
sadly... no minidump file... no idea why.
weird thing is, I turned on the laptop an hour later... and it logged on windows, perfectly... no errors or anything...
I'm keeping this updated here, but I'm pretty sure I'll just take it to the tech support in a couple of days... maybe fighting against it isn't worth it hah!
again, thanks for your help so far.
