Virtual Box constantly crashing.

[s1lenc3]

Hello, I've installed Windows 8.1 x64 on Virtual Box using Windows 7 x64 host OS. Yet it constantly crashes after 20-30~ seconds after starting. Sometimes it takes longer, however, it's just a matter of time. Could you help me out solving this problem? There's 46~ percent of used memory (out of 4GB) before and after using the Vbox, perhaps i should allocate less memory for the VBox (since I've given 2gb)? I've attached the error and log files.

You have more memory assigned to the guest than you have available for one thing.

Thanks, I just found out that it must be in a powered off state instead of saved, in order to adjust the amount of ram. Would've just done that before. Thanks anyway. Cheers!
