My laptop, a Dell Studio XPS 13 has been working fine for the past two years. However, a few days ago after intermittent lag spikes while gaming, it froze and I had to hard restart it. After that, it kept freezing not long after logging in, and through gradually turning startup services on one by one I discovered the cause of it to be WLAN Autoconfig.
Turning it off enables my laptop to run perfectly fine on normal mode, sans wireless networks connections, but as soon as I turn it on again, it begins to lag and processes begin not responding until freezing completely. However, it works in Safe Mode without any problems at all, and I have no clue why it won't do the same normally.
The night before, I had installed a Windows Update, but nothing went wrong up until the crash the next afternoon. System Restore is not an option, because I tried it already and while my laptop worked temporarily, it stopped working again after a restart following the downloading and installing of that earlier Windows Update, and now for some reason says I have no restore points. As for the update, I made sure to uninstall all the updates made on that day, but it didn't have any apparent effect.
Thank you for reading all this, and help would be greatly appreciated! Thank you in advance!
