Multiple apps won't load at all

Question

Hello all. I'm not that mac-literate so please forgive me if this question may seem redundant or just stupid.. but I'm having problems with my mac.
Several apps just ceased to load; the main ones being Safari, Mail, Yahoo messenger, Adium, iTunes, iDvd.. just to name the ones I actually tried opening.
I am currently on a PC right now, so there is no way for me to load the crash reports or whatever they're called, however this is pretty much the gist of it all:
Link (dyld) error:
Library not loaded: /System/Library/Frameworks/JavaScriptCore
Referenced from; /System/Library/Frameworks/WebKit.framework/Versions/A/WebKit
Reason: no suitable image found. Did find:
/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/JavaScriptCore: unknown file
type, first eight bytes: 0x38 0xC0 0x00 0x00 0x81 0x83 0x00 0x00
/System/Library/Frameworks/JavaScriptCore.framework/Versions/A/JavaScriptCore: unknown file
type, first eight bytes: 0x38 0xC0 0x00 0x00 0x81 0x83 0x00 0x00
That is pretty much what it said for every single crash logs of the stated apps that won't load.
I'm not sure what exactly preceded this, but the first time I noticed this was when I went to the mall and picked up a signal (airport) and it prompted me if I wanted to get on it and I clicked yes.. and when I tried to load Safari it wouldn't open.
Could anyone please give me some insight? Or am I not making sense and better off going to CompUSA to get it checked out??
Oh and might I add that when I try to open "HELP", it won't open, neither would "Software Update"

Something doesn't compute maybe?
I think at this point you should make sure your data is backed up and do an Archive and Install of Mac OS X. You'll need to get out your Install Disc 1 again and hold
down the 'C' key at boot up. Make sure to select preserve user settings and network
settings... You'll need to run software updates and probably re-install some applications after an Archive and install.
