My PC seemed to be doing better for a few hours day. I deselected "Use hardware acceleration whenever available", in Firefox and Youtube videos started playing. But, then BOTH Firefox and Chrome stopped working. I reselected hardware acceleration, but nothing changed. Loading is worse than dialup. I can open Firefox or Chrome, and once it finally loads I can type in a website, and it will take an hour or longer to load that site. When the site finally loads, forget trying to do anything, because it takes another hour for whatever you are trying to get to in that site to work.
I rebooted, and noticed NVIDIA in the startup tray. I went to startup and deselected the option, I also npticed There is something called NvCpl. I deselected that to startup as well.
I am only able to get online using safe mode with networking, and I can use my mouse, but once I touch any key on my keyboard, everything will lockup. I used Malwarebytes in Safemode, and it identified Adware.ChinAd C:\Index.html. I quarantined it, but doing so did not improve anything. I can edit pictures or text documents in my PC, but I can not get online, and it takes an eternity for virus software to open and run.
I am using my husband's computer now.
