Can I ask another question regarding the problem I posted earlier.

"I'm running Win 2000 on my office machine.

It has a CD drive fitted. When I put a disk into the drive the green light comes on but I cannot see it in Windows Explorer.

I brought in a standalone USB CD drive that I have at home. If I plug it in the Plug and Play recognises the new device but, again, I cannot see it in Windows Explorer.

In groping around the Properties of both drives I see a reference to:-

c:\winnt\inf\cdrom.inf

and references to:-
wnnt\system32\drivers\cdrom.sys..............."

If I delete those files and ask my PC to re-install them will it install files from something like a CAB directory on my machine or will it go on to the Microsoft site on the internet and download fresh ones. I read somewhere that, although the machine looks as if it is searching the internet it may actually not be doing so.

How can I make sure that it is not simply re-using the ones on my machine?

TP

You might be able to download the drivers by themselves and save them to a specific place. You could then tell the system to look there for the drivers.

Good idea Haystack.

Just need to see where Mr Gates has them stored.

TP

What about drivers from the actual device maker.

H.

You are right in suggesting that. What made me think there was a deeper problem was when the PC failed to recognise the USB plugged in CDROM.

TP

Mind you XP is pretty good as spotting new hardware and figuring out how to handle it.

H.

Snag is that I'm on 2000 on this office PC.

No, what made me feel that looking for the device maker's driver was the experience when I plugged a CDROM into my USB port. The machine recognised the new USB device, System Manager saw the drive, but Windows Explorer would not give it a drive letter.

What is this cdrom.inf file? Might this be the problem?

TP

It describes the device driver and how to install it. You can view. It is in text.

Hi Guys I have had a lot of trouble with one PC. It was very very slow. CPU usage in task manager is at 100%. Culprit appears to be SPOOLSV.EXE, which is using 99%. Any ideas how I can fix it??

Bob

Bob - I'm sure the cavalry will be on this thread soon, but in the mean time -http://www.neuber.com/taskmanager/process/spoolsv.exe.html

Tks Skinny

Believe it or not I have fixed it myself by deleting all my printers in control panel.
CPU usage now looks normal. If I have trouble after reinstalling printer driver. "I'll be back"

Thanks Haystack,

Mr Google suggests it could be a registry problem:-

http://support.microsoft.com/kb/270008/

Snag is I have not the nerve to tinker with the registry as I know my CD drive, which I'd need for a 'recovery' is not working.

Frying pan to fire syndrome.

TP

Am I not right in thinking that this Upper Filter entry is a bug?



If so, any suggestions as to the safe way to get rid of it?

TP

Tp first couple of entries might be usefule - http://www.google.co.uk/search?sourceid=navclient&ie=UTF-8&rls=GGLD,GGLD:2004-12,GGLD:en&q=upperfilters

TP, have you ever used TweakUI by any chance? It has a facility to hide drives.

K.

No never.

Sk,

Yes, I've seen that. It was the reason I was looking at that entry.

Presumably I delete the whole of that UpperFilters line. Yes?

TP

If you uninstall the driven then those entries should go. Didn't you say earlier that you had done that already. What is the whole entry if present at all when you uninstall it?

H.

The entry that I photographed above remains the same when the drive is uninstalled.

Reading some more threads, such as this one that follows, it does seem that the Upper entry could have crept on to my system through looking at Ipod software.

Anyway I am pretty convinced that this GEARAspiWDM is the problem.

I'm not sure which registry entries are the problem, but if you want to play around with the registry, then select a key in the left hand pane, and click File - Export to save the key to a file. You can then delete or modify the key and restore it by opening your saved file.

Only use this method for minor registry settings, there are some parts of the registry where changes may immediately make your system unstable and it would not be possible to recover in that way. Idealy, you need to make a ful registry backup and be able to restore it from your boot CD.

BTW, will your system boot from your W2K setup CD?

Op,

"be able to restore it from your boot CD.

BTW, will your system boot from your W2K setup CD?"

No. This was going to be my ultimate problem. The machine will not see the CD drive so I was terrified that I might screw the operating system and not be able to recover with a CD.

Anyway, the long story has come to a happy end and having removed that Upperfilters entry in the registry I can now see my internal CD drive again.

Thanks to all of you who have patiently fed an assortment of ideas. It is annoying that my various bug tracing software progs could not spot the error in the registry.

Thank heavens for threads like this and the marvel of Google.

Back to do some real work now.
