My computer is slow when I right click files.?

My PC is slow at locating files on the hard disc, so when I open a picture to view it, or when I right click some MP3 files, it takes about 6 seconds to locate it and give me detailed info about it.

My hard disc has a 232GB capacity of which 45GB are free.

I think it's probably because of the limited free space, but I have heard that windows does that over time, because of the many registries created through months of use.

I will not use a registry cleaner because I don't trust them.

Thanks in advance for any info you have.

PC Specs:

Dual core viiv

1GB ram

7500LE GeForce

Windows XP professional updated

Firewall, antivirus

I dont have much spyware.

Is there a way to fix this problem, other than the obvious "delete your stuff"

some times with my computer it slowes down and i do a error checking and its good as new. but if u go to my computer right click and the c drive go to properties then in the tabes go to tools and then go to error checking. click both checks and click run. then u have to restart your computer to start it. note it will take a while at least 3 hours prob lot more with such a big hard drive. and it might not hert to rerun diskdefragmater and run disk clean up
Of course run your Anti-spy-ware and Anti-virus but I have a feeling that you could use a good Defrag.
