up to 5 min to load windows98

Hi!

I have an old intel p2 350 with 64 MB Ram, 6 GB hard drive (2 partions 4GB&2GB)

5 years ago when I got this PC, windows 98 didn’t took too much time to load.
But now, the windows 98 loading screen can take up to five minutes to FINALY enter in windows.
It is not because I haven’t formated it in five years, the last time I formated it, it was two months ago.

Can you tell me if it’s the hard drive, or the PC that is getting too old.

Thanks!
