Critical - Sleep Transition Gone Wrong

Ok so for hours now ive been trying to figure out what is wrong with my
computer, its a toshiba, and ill explain what happened. So I was on my
computer when i realized my battery was unplugged and it began to shut off, i
plugged it in quickly and waited to see nothing responded, so i thought it
was frozen so i held the power button down and turned it off. When i turned
it back on i found that i could log into my user and everything else was
fine, until my background and start menu wouldnt appear. I could use task
manager and use that to open other files. Everything is working except the
start menu and it is driving me insane. I was looking for the problem when i
came across event viewer and found a critical just around the time of when my
computer stoppped working and this is what it says:

The last sleep transition was unsuccessful. This error could be caused if
the system stopped responding, failed, or lost power during the sleep
transition.

It doesnt give me any help on how to fix the problem and i was hoping
someone could help me out.
