Windows 7: An unknown device appears

It looks like your RAM supports XMP profiles, I'm hitting a bit of a snag on your motherboard though. The ASUS page for your motherboard suggests it supports XMP:

However, having read through the manual I can't find anything pertaining to XMP profiles. It suggests you have to manually set your RAM timings.

If you're not 100% certain of how to do this then leave things as they are.

Have a look through your BIOS Advanced Mode and see if you can find XMP profiles. If you do there should be two pre-loaded options of Disabled or Profile #1. Disabled will keep your RAM at the default 1333MHz, if you load Profile #1 that should set your RAM to 1600MHz. The screenshots below are from my BIOS and may not represent the layout/options you have in yours, they're there for reference only.

Once set, check your target timings for DRAM have changed accordingly.

If you can't find XMP within the BIOS then I wouldn't worry, you'll never notice any difference between 1333MHz or 1600MHz anyway, and even benchmark results can show only marginal increases in performance.

Legacy USB are disabled now. There is still the unknown device.

As the ram, with this configuration(1333), will increases the duration of live ?

Well that's ruled that out then. Set it to Auto and leave it be.

Slartybart : Screen shots, Done.


I have all my information on CD in case to restore the system with Acronis.

I agree with Skim, is becoming a little tedious

Thanks, yes it is tedious

I'll reiterate my suggestion from a day ago -> uninstall / remove the unknown driver
reboot and see if it gets reinstalled (I do not believe it will be installed after you reboot)
or
Use your backup and restore

Your choice

edit: Thanks for posting all of the device screens. I tried to find a command or utility that would dump the information, but either I couldn't figure out how to isolate the unknown device in a list, or the information was not presented using the tools I tried.

Your patience and diligence are very much appreciated. Sorry if I sounded curt above, I was really only agreeing with you.

No problem.


I not know if there will be other thing that can be done. I downloaded the malwarebytes free version(I have not installed yet). But ESET found nothing, so maybe have the same result.

Concerning the restoration, i can activate Windows so many times i want ? It is the boxed version.

When you uninstall the unknown device, if there is a checkbox or prompt to uninstall the software answer yes.

If ESET didn't find anything, then Malwarebytes (Mbam) probably won't either. It won't hurt to run Mbam though, it's fairly quick.

Concerning restoration: I was referring to your post that said
I have all my information on CD in case to restore the system with Acronis.

To answer your question, yes you can install and activate Windows as many times as you want with a retail box version, on one machine.

I did, and did not show any message after restart. The list does not show any unknown device.
Although no longer appears, I do not feel quite relieved Because i not know which was the origin of that thing: by software, hardware, or virus.

So ?

1- If it was a virus, would be only affected the C drive, right ? (Since I have only the image of the C drive)
2- If it was a software, was originated by using HWMonitor ? (1.22> 1.24> 1.22 : version without installing)
3- And hardware, perhaps by a recent windows update?
