Two hard drives and still out of space

Old HP Pavilion Entertainment PC / windows 7 / AMD Turion 64 X2 Mobile technology TL-60, 2000 Mhz, 2 Core

C / G Hard drive - patitioned at 29.11 gb NTFS (this is where the operating system is) and 203.77 gb NTFS

D / E Hard drive - patitioned at 29.11 gb NTFS and 137.47 gb ntfs and 131.51 gb unallocated (I tried to add to D but it didn't work - it made D dynamic though)

The computer runs on c and it is completely out of space - I can't even do a system image. I have performed numerous disk cleanups - the only thing left is the actual program files. The amount of available space varies but it's about360kb...

I have all this hard drive space - how can I fix this?
I didn't partition any of the drives.

The drives are
WDC WD2500BPVT-22JJ5T0 ATA DEVICE
WDC WD3200BPVT-00JJ5T0 ATA DEVICE

It's telling me that I can't write to the cd drive so I can't use the repair disk - it won't read from it.. I ran all the troubleshooting on the cd/dvd drive and I don't know what is wrong with it. It's definitely a dvd write drive.
PIONEER DVDRW DR-KD08HB ATA DEVICE

I performed a system image to an external hard drive. I also tried to perform a system image to the d/e drives but when I remove the c/g hard drive and only install the d/e drive - it says that it needs windows.

I only have the windows upgrade disk - not the entire install. it was an upgrade disk from Vista.

I know it has to be something easy.
I appreciate any help.

 

I forgot a detail -

the hard drives are empty -
c: 183 mb free of 29.1 gb - this is the drive that's full
d: 5.67 gb free of 29.1 gb
e: 134 gb free of 137 gb
g: 203 gb free of 203 gb
