BSOD system service exceptions

Were you playing a steam game at the time of the crash? Also, how much free space is available on your C drive?

I noticed in your event log that AiCharger failed to load drivers quite a few times. Do you use the iPod charger-thing that Asus provides? If not, I'd uninstall that thing.

The bugcheck 0x0000003b can sometimes be caused by issues with the video card. Are you running updated drivers (from the manufacturer, not from Windows update)?

Do you mean you never update Windows? If that's the case, you need to run Windows update.

I highly recommend you allow Windows to check for updates automatically. You can choose to let the updates get installed automatically or not. Personally, I let it check but not install unless I select the updates.

No. Updates don't take a lot of space. But, there isn't a lot of space left, so make sure you keep an eye on your downloaded files/plugins/etc, so you don't run out of space. You should consider installing another drive for your file storage and game save locations.
