Frequent BSOD's, ntoskrnl and usb drivers

[Newtype]

Oh, and it is normal for my computer to be a little slow when verifier is enabled right?

 

[Thedoctor44]

Yes, Driver Verifier slows down your computer but it should return to normal speed when you disable it.

 

[Newtype]

Here's my most recent one, I believe driver verifier is enabled

 

[Newtype]

When I returned to my computer this morning it was on sleep/standby (Even though I have it set not to do that) and when I started it up apparently it gave me the error prompt and another dump file.

I know BlueScreenView isn't as reliable as WinDbg or whatever it is you guys are using, but I like to check it out anyway after my BSOD's and it's pointing to ISCTD64.sys again. I didn't think I had it installed because it doesn't show up in my uninstall programs list, so I'm not sure how to get rid of it.

I see the driver file in the path: C:\Windows\system32\drivers\ISCTD64.sys but I don't know how to remove it or if it's just safe to delete it from there. I'll hold off on messing with it

 

[Thedoctor44]

You are correct.

The bets way to remove it is to find the actual program the driver is for then remove that.

The driver ISCTD64.sys is the Intel Smart Technology Driver.

Can you take a picture of your programs installed via control panel?

Unable to load image \SystemRoot\system32\DRIVERS\ISCTD64.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for ISCTD64.sys
*** ERROR: Module load completed but symbols could not be loaded for [COLOR="Red"]ISCTD64.sys[/COLOR]

Here you go

 

[Thedoctor44]

Can you find anything in your device manager?
Are there any yellow triangles or any devices that might be related to the driver?

 

[Newtype]

I found Intel Smart Connect Technology Device under system devices. Should I uninstall it from there?

There's also a SM Bus Controller under "Other devices" with a yellow triangle above it, if that's worth noting.

 

[Newtype]

Here's another one that just happened while watching videos on Youtube

 

[Thedoctor44]

It's recommended to run and download the Intel Chipset installation utility from here.

https://downloadcenter.intel.com/Se...on+Utility&ProdId=816&LineId=1090&FamilyId=42

The SM Bus Controller is the system management bus controller that is a chipset driver, this means it's important to update it.

Also please remove the Intel Smart Connect Technology Device from your device manager.

 

[Newtype]

Alright, uninstalled intel smart connect and installed Intel Chipset.

 

[Gandalf]

Please post an image of your latest Device Manager. Thanks

 

[Newtype]

Here you go

 

[Gandalf]

You have an Unknown device.
Since this is the first DM in the thread (I think), please delete the Unknown device and reboot.
Recheck the DM. Do you still have an Unknown device listed?

Uninstalled it through Device Manager and it reappeared after I rebooted

This might help you find a driver... It's FREE.

Just be sure to read everything, before clicking anything.
Being free, it has tricks to get you to buy the Pro version.
But, if your careful, it works well for my Win7 PCs.

That software found me an intel driver which seems to have done the trick. Once I installed it I no longer have an unknown device in device manager now.

Also attached a dump from a BSOD I got before updating that intel driver, verifier wasn't enabled for this one though. Really hoping that driver fixes all this .

Anyway, thanks for the help so far you two

You have some USB functions in the stack.

What devices are plugged into your USB slots?

 

[Gandalf]

I too hope we have stemmed the tide of BSODs on your computer. Time will tell. Please, just don't install any new software of any kind, until you are sure your BSOD issues are resolved.

 

[Thedoctor44]

I agree with Gandalf but I was just looking ahead, lets see if that driver install fixed the issues first.
