Um, no offense but this is Related to DMICall.sys Sony DMI Call service driver.

Yours dated 2000. It cant possibly work in win 7

So how can I go about fixing it?

I would remove it at least to test or permanently if it is the cause. If it is critical I would update it to the newest version.

I know this may sound a little dumb, but where would i remove it from and also, where could I find an updated version?
Your help is much appreciated.

Given that the hardware is about 2.5 years old it is something you probably installed. To uninstall it go into control panel>programs and features>find the program and click uninstall

You can try to find an updated version by googling it.

I can't find it there, but it is in c:\windows\system32\drivers

Please help as this is driving me crazy
