Check your network hardware. Updates for network cards aren’t all that common, but if your card’s manufacturer offers a newer driver, download it. Resetting your router and modem can help with connection problems, too. Most routers and modems have reset buttons, but pulling the power cable for a second or two can do the same thing. Don’t cut the power for much longer, or the hardware may reset itself to factory defaults.
Still having problems? Call your ISP, which can tell you whether the problem is on your end. As a last-ditch measure, the ISP could reset the master connection to your home.

Hardware problems are hard to diagnose and solve. First, confirm that you aren’t just getting the latest wave of Windows updates, which can automatically restart your computer during installation. Then work on updating all of your critical system drivers. Your graphics card, motherboard, and network card drivers are crucial.
“Sometimes it can be viruses, sometimes it can be adware, sometimes it can be overheating, and sometimes it can be something as simple as making sure your video card is updated,” Geek Squad’s Meister says.
Is your computer making weird noises? If you’re lucky all you’ll need to do is give the machine a thorough cleaning. Modern computers have safeguards that shut down the system if a component is overheating, which can be the cause of frequent restarts when you’re running resource-intensive programs or games.

If you’re not running your Web browser and are still getting pop-up ads on your desktop, you’ve most likely installed adware—a program that displays unwanted ads. Although benevolent adware exists, most of the time adware is up to no good. Getting rid of it isn't easy. “There’s a ton of little system-utility tools out there that promise to clean up everything, with names like PC Speed-up, PC Speed Pro, PC Speedifier,” Geek Squad’s Meister says. “A lot of times those programs are not going to do much. Some programs will work, others are snake oil.” Running a full scan with credible antivirus software is your first step. If that program doesn’t find and remove the adware, turn to Malwarebytes Anti-Malware Free, a great utility for removing all types of malware. Just make sure to disable your standard antivirus software before running it.
“Multiple antivirus programs working at the same time will often result in problems,” Falcon Northwest’s Petrie says. “You only want one active, real-time antivirus scanner installed, but it doesn’t hurt to run an additional ‘on demand’ virus or malware scanner.”
Searching online for the name of the advertised product can sometimes yield solutions from fellow victims. If all else fails, there’s always the nuclear option: a complete system reinstall. It might take a long time, but it’s the only surefire way to remove adware or spyware. Remember to back up all your personal files.
