Question A Device Attached to the System is not Functioning

For some reason my computer becomes unresponsive after sitting going to standby, but only sometimes, like two-three times a week. The screens go blank, so I try to remote desktop it and it says :

A Device Attached to the System is not Functioning

Very odd, any ideas before I reformat? I did just install the OS a few days ago, BUT I did flip the reg from ATA to AHCI and then did so in BIOS, but that never caused it only other test machines i've done this on.

Take a look at the 'Windows Logs' and 'Applications and Services Logs' in Event Viewer. In the Windows Logs look for warnings and errors logged under both Application and System. In the Applications and Services Logs look for warnings and errors logged under both Hardware Events and in the Microsoft directory.

I agree that the ATA>AHCI Reg hack and BIOS edit shouldn't cause any issues, and the error message that "A Device Attached to the System is not Functioning" is so ambiguous that a look at the Logs may point out exactly which device the error message is refering to.

I would also pull up device manager and see if you have any yellow ! by any devices.

It just did it again while I was in a meeting ... the screens go blank and act like they're disconnected.

I got home a few hours later VPN'd in, and remote controlled it, logged int, and that is where I get the device message...and I can only click OK...freaking weird!

Like I said, fresh format of Win 7 x64 SP1 ISO I got off MS's technet site. The only change is that I added the SSD.

I dived through windows logs each time, nothing stands out, no drivers missing...It only has an error that it was unexpected shut down (when I hard bounce it to get it back).

The only oddity I see show up that might be related is :

Quote:
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.
EVENT ID 10
Source WMI
Level ERROR

I am trying this to resolve it : http://social.technet.microsoft.com/...-bb9912ca64d7/

Vivi, I think you're on the right track; have a look at this discussion:

Windows 7 - WMI Event ID 10 "//./root/CIMV2

If it happens again, i'll see if the same error follows, even after the fix in that technet I posted.

So I had it happen again. I tried video drivers from Dell's website, since I am running an opitplex 960, and it happened...albeit took an extra day to occur.

Checking event viewer, still no issues that stand out.

I thought it was possible misaligned SSD, but it is indeed aligned. I just can't tell if it's software of physical, grr.

I do have 1 attached mechanical HDD, but that was there prior to the install of the SSD.
