Hi, welcome to the forums

We need to ask how/where you got your copy of Windows 7 before we can really progress any further.

Windows 7 Ultimate x32

Ok I read the article, that might be releated cause I had a little problem with windows xp and did a bios battery reset and changed some wires, but how didn't understand very well, can you explain to me in some familiar terms? Sorry I'm a bit newbie.

I've just found

Another classpnp.sys hangup

Also, if you can access the BIOS i've read somewhere that classpnp.sys is something to do with SCSI (not 100% sure how accurate that is) but if you can enable IDE emulation from within the BIOS it might help. You will need to press either F1, F2, F10 or F12 during the 1st (P.O.S.T screen) to access the BIOS then normally under Advanced Settings you'll find SCSI information.

I accesed Bios ,but under Advanced Setting i didn't had SCSI information. And I tried some of these thing from that thread but it didn't work. Got this problem for 5 days .
Edit: Now I try to reconnect the graphic card.
Edit: Removed and reconnected both graphic card and HDD but still the same problem.
