I see you also have a problem with explorer.exe in this post;
I would scan for malware first. Viruses, spyware, and trojans.
explorer.exe drive not ready- Drive A: may be open
this message is appearing everytime my windows xp sp2 starts, since YESTERDAY,
The Drive A: is the floppy disk
i dont know what to do
how can i close it
should i open my pc and on the inside of it maybe something could be wrong there!
