XP SP2 I tried to install SP3 recently but failed. Since then my machine always reboot it self every 30 seconds. I booted from CD drive with XP cd went to recovery mode and type FIXBOOT. Now I found out in my second harddisk has several folders with name such as: 0ae4089b57e590b744e373 2a884b442db579e38084a .....etc. I cannot delete these folders. Each of these folders contains dll, exe and inf files, contents of them are exactly the same. Any idea what are these folders?
