[HELP!] My mac is acting weird.

I don't really know how to describe it but, when I start up my mac, log in, there is just a white screen, then after a few minutes the bar up top shows up with the apple icon. But I do not have a dashboard, i don't have icons up to the right either, such as wifi and battery life, that's gone. I only managed to open Firefox through Spotify (which was the only thing that popped up when I first started my computer.)
My mac froze when I was playing Garry's Mod, and after I restarted everything was like this. Is there any solution to this? I have no idea what's wrong.

Copy and Paste commands doesn't seem to work either.
I cannot access Finder.
I cannot download anything.
I cannot open WoW (says there is no internet connection which is obviously wrong since I do).
The only way for me to access files is to go to the Apple icon and press Recent objects.
I just realized it's not just WoW saying it's an error, it's every single program with almost a diffrent error everytime.

G'day and welcome to the forums.

What mac and what operating system? Hard to help without the vital stats.

Macbook Air
10.7.4

Boot to your Recovery Partition: Hold down your Command + R keys as soon as you hear the boot sound. Once in Recovery, select Utilities, then select Disk Utility, Highlight your Macintosh HD and select the verify tab. Repair if necessary.

Thank you.
I had already repaired it several times, but I thought oh well, i might just try one more time.
So I opened it up and literally SPAMMED repaired on everything i could.
So it works now

Another hint: Make a backup as soon as you can. When a hard drive begins to act up like yours has, it's telling you that it may fail at any time. Again, make a backup now.

I got the macbook in 2012, i believe it's 11", 64gb ssd disk and an i5 1.7GHz processor.

Apple has a drive replacement program for that model..
