First you need to isolate the scope of the issue. Meaning, where it occurs and where it doesn't. Start out by creating a new user in Windows. This will allow you to log into your PC with a fresh and clean local profile; including default browser behavior settings. Now start testing via going to...

Most ransomware don't install rootkits unless aiming to completely hijack the OS with a ransom message and instructions upon boot. But for the majority, they run from a browser and execute remaining only in RAM. None of the binaries of the malware stay on the system so as to explicitly prevent...

Depends on if the encryption key was made public / reverse engineered, leaked...etc by anti-virus vendors. If so, they might be able to be decrypted. Otherwise, they files are lost forever unless you have a backup of them. I recommend installing Bitdefender AV and performing a full scan. Oh...

You got hit with ransomware.

https://nvd.nist.gov/vuln/detail/CVE-2017-14491 Basically it's a DNS process overflow vulnerability. You can mitigate it by setting the TCP/IP (v4) properties to use static primary and secondary DNS rather then looking up host names via your own router acting as a forwarder via it as provided...

According to Dell, the following WiFi modules were available at the time for that Dell Laptop. Dell Wireless 1390 (802.11g), Dell Wireless 1490 (802.11a/g), Dell Wireless 1505 (802.11a/g/n) The 1390 is limited to 54Mps. You can get after-market wireless cards, but you'll need to check if it's...

Did you run a Dell ePSA boot diagnostic? Be sure to update the BIOS to the latest version. To run diags, press the F12 key upon powering the unit on and choose diagnostics from the boot menu. Also, you might need to turn off Dell Fast Response Free Fall Sensor in BIOS if available

How old is the TV? Also, does that occur with any other source of input to the TV (console, cable/sat TV box..DVD..etc)? If the answer is "yes", that could mean an internal electronic fault within the TV itself.

Try scanning with Trend Micro HouseCall and Malwarebytes https://www.trendmicro.com/en_us/forHome/products/housecall.html https://www.malwarebytes.com If you want a recommendation for a good (really good) AV, then I recommend BitDefender. I personally use the Antivirus Plus edition, but...

Most likely a drive failure. Have you attempted to run on-board diagnostics? Usually it's found in a boot menu the moment you turn on the laptop and just before Windows loads.

Replace the CPU? Possibly. It's also possible that the tests failed because of a problem with a SODIMM (RAM module). You can try downloading and running Memtest86 and the official Lenovo utilities. If it's under warranty, they should be able to assist with the RMA process to get it repaired...

Years ago, I spilled some water on a Unicomp keyboard. I let it dry out for a week, but I had a similar issue. Pressing multiple keys or even a single key gave miss registration typos as I was typing. Honestly, I'd replace the keyboard. To verify, just plug in an external USB keyboard. If the...

Depends on the laptop. Some laptops can have the entire keyboard replaced under the palm rest. They're not expensive, and can be found between $16 and $21 in most places. It could also be a loose ribbon cable connection. If so, you can take the laptop apart and remove, reconnect the cable to...
