I have been using 3G USB stick on my laptop which has Win7 64 bit installed. It worked fine for last 1 year and suddenly one morning when I tries to connect USB it said
Please connect device. I unplugged modem and tried multiple times but system couldn't detect it.Then I looked into device manager and it showed yellow flag on device drivers for USB modem with below error:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

I re installed device drivers but no success.
I Googled about it and only solution I found is press F8 while booting and then disable driver signing. Just wondering how it worked for 1 year and suddenly stopped working.
Note: Previous day I had changed some services and set start up type as Manual, I don't really know which all services I modified. Can this be an issue?

Since you have changed system services and don't remember which ones, you can try System Restore to set your system back to a point previous to the changes. System Restore can be found by going to START > All Programs > Accessories > System Tools > System Restore.
Typically one the latest restore points are shown. If you don't see a date before you made the changes, you may need to check the box at the bottom to see more restore points (see image below).

Absolutely it will be. You should not change services unless you know what they do and how it will affect the system.
