I keep getting "Error compiling." when trying to upload sketches

I've been using my Arduino Uno for a few months without any problems. Today I tried to compile a sketch and it gave me a Error compiling message. It didn't give me any errors in the output field. I tried it again with the Blink sketch and it gave me the same error.

If it's at all helpful, this is what the output said,

C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avr-g++ -c -g -Os -Wall -fno-exceptions -ffunction-sections -fdata-sections -mmcu=atmega328p -DF_CPU=16000000L -MMD -DUSB_VID=null -DUSB_PID=null -DARDUINO=105 -IC:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino -IC:\Program Files (x86)\Arduino\hardware\arduino\variants\standard C:\Users\PHYBER~1\AppData\Local\Temp\build7313227511724971617.tmp\Blink.cpp -o C:\Users\PHYBER~1\AppData\Local\Temp\build7313227511724971617.tmp\Blink.cpp.o

Any help would be greatly appreciated.

Under File:Preferences, check the verbose output boxes, recompile again and post all the notes that come up.

Perhaps your IDE got corrupted. You could try reloading it.

The verbose output boxes were checked, that was the entirety of the output. I uninstalled the IDE and reinstalled it, it gives me the same problem.

When I select Uno, and Blink sketch, I see all this when Verify button is clicked. You can enlarge the IDE window and the lower section, highlight all that is there:

That's everything.

Wow, that doesn’t look right at all.
I don’t know what to advise when it just stops like that.

Any chance its a Windows permission issue, not letting the IDE create needed folders or something like that?

I just tried running as administrator, I got the same error but it gave me a lot more information.

Ok, we need some software guru help here. I don't all that should be coming up. If you compile a 2nd time, does it do the same?

It does the same thing every time.

Okay, I'm calling in the cavalry - sent a request to the other moderators. Some one is bound to have seen this.

What is your computer & operating system? Does it have any recent upgrades/patches?

Is your C drive full?

I'm running Windows 8. 1.30 GHz processor, 2GB Ram. It's a Toshiba Satellite C855D-S5302. No upgrades of any kind. I'm using 38GB out of 287GB on my C drive.

I don't use Windows but are you using the right IDE for the right OS? I mean, are you using a 32-bits IDE on a 64-bits OS? Have you downloaded the IDE installer or the IDE package? I see "programs-(x86)" into your path.

Try completely removing the IDE and downloading again the installer.

Windows 8 x64 is perfectly capable of running 32bit programs. Phyberlogik has already reainstalled the IDE. His (and my) problem persists, even when using the .exe installer.

I've found that if you're using Windows 8, refreshing your system seems to fix the problem. I know it's like going after housefly with a bazooka but it seems to do the trick.
