Windows Vista Vista prefetch files corrupt

Hello ,
When i start this computer (MSI Notebook) it says that 1 or more files couldnt load because they are corrupted, and shows the Prefetch folder as the source of the troubles... (but the programs still start without problems)Now it was possible in XP to delete the prefetch files and XP would rebuild them at the next boot. But is it possible with Vista? Can I do the samme action? Vista recommends to run chkdsk, but when i restart the computer, chkdsk just quits without any checks and the boot sequence continues...
What should I do? This Vista version is a Business version.
Thank you for your help!

 

Thank you for your help, I used Ccleaner instead (I did it before i posted this thread!) but didnt touch the Prefetch folder. Now, after I read your answer I went right away to the folder pointed at it and clicked "properties ".. The folder is empty. And if I try to open it I get this error message, " This folder is corrupt ". What do I do next? Could I delete it and create a new one?

 

Well couldnt delete the folder either... And sfc /scannow didnt worked.. In fact, the CMD window just went dead (And again a prefetch error)... I couldnt write in it, and i couldnt close it either... I did a restart (Hard reset, had no other choice), pressed F8 and choosed safe mode with command console and wrote chkdsk /f. The computer wrote that it had to run the task as a scheduled task and asked me to reboot. I did... Tooks a looong time and rebooted again, but then all the prefetch errors were gone! Then I ran sfc / scannow from the CMD windows ant it went well. It repaired some files and I was (at last!)this time able to close that window. I restarted it again and wrote chkdsk /f and it (again) ran after the next boot. This time all went smooth! It corrected somme minors errors. And now Vista runs smooth again!
Really thanks for your help! Im pretty experienced with XP, but have not much experience with Vista, so your help has really been appreciated!
