Running Fedora 22 from live USB

So i fired up Fedora from my usb and i have to say it's butter smooth compared to running it inside Virtual Box. But there are lot of problems.

These things didn't happen when i was using Mint 17 however i don't want to use other distro right now because i'm learning from a book that is based on Red Hat and Fedora.

I can't even update Firefox without the whole thing crushing down.

run memtest and see if it spits back any errors.

The only time I have seen this type of issue is when 1 of my ram modules was dying.

Have you performed a package update on a read-only live iso?

LOL I tried but during the process terminal told me that I run out of space. I have only 8GB USB key with 7.4GB of usable space. After the installation of Fedora I had only around 600MB space left and to install all the updates I need 850MB. Sad times...

It's ok now. If my RAM was dying i would be seeing something similar when using windose. But win7 runs fine.

99.99999999999% of the time, you are correct, but sometimes you do not see the problem unless you are completely stressing your ram.

Sometimes weird crap just happens like that.
