I suggest that you do not delete the prefetch files.
If you do, it will cause your computer to take longer to boot and longer for your aps to open.
If you know when the problem began and it is less than three weeks ago try using Windows System Restore to reset your system state to a workable condition.
To access Windows System Restore click start/programs/accessories/system tools/system restore.
Choose a highlighted date from before the problem began.
Have you recently used any kind of registry cleaner or any ap that changes or modifies the registry?
Have you scanned for malware?
Do you have the Windows XP CD?
Can you access the internet with Internet Explorer?
Is your system fully updated with SP2 and all the subsequent Critical Updates?
