I done goofed [solved]
I got my raspberry pi model b yesterday, put some heatsinks on it and started messing with it, after i got it up and running i did what i always do, i overclocked it, and now i'm having some issues, when i first started using it, it worked fine but now i can only get it to show up on the display in hdmi safe mode, before it would do it in normal mode, i have undone the overclock and reformatted the sd card and put a new image on it to try and see if that fixes the issue but it didn't, i wanted to know how to go about fixing this, i am powering it with a supercharged usb port from my desktop, i'm using a 22 inch led hdmi lg monitor and the pi has a standard wired keyboard and mouse and a cat 6e ethernet cable going to it and a 4gb class 4 pny sd.

The board of a Raspberry Pi does not contain any components that can be altered by the user. Other than physical abuse (dropping, tearing bits off... ) or electrical abuse (static electricity, higher than specified voltages applied to the connectors... ) your RPi board is the same now as when you first unpacked it.
Any changes that you think are persisting must therefore either be in the SD card you are booting the Operating System from, or in connected equipment such as the display.

Re: I done goofed
Not completely true. If you run a large current through a PI's (poly)fuse it will blow, and for a few days (until the fuse recovers) your PI "won't be its old self"! 
But yes putting (even for a very short time) more than 6V on the PI's supply will blow the fuse, ("higher than specified voltages applied to the connectors...") so yes, in that sense you are right.

Re: I done goofed
well i rebooted it after work today and it started working right again, so i guess that fuse recovered.
