Thank you for a quick reply!
It's going crazy somehow. I again just checked the settings and suddenly 8191MB was allocated though no paging file is still checked. That made my internet work again. F-Secure has crashed though (edit: it managed to restart itself now) and I wouldnt want to reboot again just yet because it's quite hard to ask for advice with mobile phone internet in case it stops working again.. Oh, and now that I checked again the checkmark is finaly in system managed size as I set it in the first place..
Should I let it be so or use the custom size, and if latter, what should I set for initial and maximum size?
I dont know if this is related, but just before this I unpluged the other 3 HD:s to help solve the BSOD issue. After that, everytime I boot it says for half a second that no hard drive has been found. However it gets to the windows without problems. Also the DVD-drive went missing (though now it seems to be back again, havent tested it yet though). Edit2: and no, right clicking the dvd drive just crashed windows explorer so now I'll be trying to restart windows.
