Peter via email asks:
Hello Aunty, I have a HP DV7 laptop that I upgraded from Windows 7 to Windows 10 which has worked fine except that when I connect to my TV using the HDMI lead, the laptop screen shrinks to half the normal size and the TV picture is missing a large part on the left side. Also the sound only comes from the laptop speakers and not through my TV. I know it’s not the laptop as everything was working before I upgraded from Windows 7. It is an official Windows 10 which I bought from Amazon UK.
Hi Peter. This is most likely to do with the driver software for your graphics card. Go to the hp.co.uk website and the “support” and “Software and Drivers” section where you can enter the model of your laptop and download the latest Windows 10 drivers for your graphics card. Once installed connect everything up and run the “wizard” that should auto detect everything and help set things up. Sometimes it helps to switch everything off, connect all the cables and just switch the TV on and set it to the HDMI channel. When you start your laptop it should auto detect that you have your TV connected and configure everything for you.
June via email asks:
Hi Aunty, I have an all-in-one desktop with a touch screen but the screen is constantly covered in fingerprints and I was told they are delicate and there are some “must nots” when it comes to keeping them clean. What is the best thing for doing this?
Hello June. Touch screens are not particularly delicate as they have been designed and tested to handle all sorts of poking with sticky and greasy fingers. I use the cheap microfiber cloths from Mercadona which I slightly dampen with a mix of bottled water and a couple of drops of white vinegar. You can also add a few drops surgical alcohol onto the cloth to help sterilize the screen as you can never be sure where those fingers have been.
William from Algorfa asks;
Hi Aunty. I somehow installed an app called TurboYourPC as it reported I had 300 errors and it would fix them. At the time my laptop was running painfully slowly so I thought what the hell. Since I installed it I cannot open any of my apps and when I can get on the internet it is so slow and I get adverts popping up every minute, I want to throw the thing in the bin. Any advice on how to get rid of it?
Hello William. This is one of many apps that offer to sort out computer problems but invariably make things worse by loading loads of junk and advertising malware onto your computer. TurboYourPC is particularly sneaky and it seems to have a pretty nasty payload that will cause exactly these kind of problems. You may be lucky and successfully remove it via “programs and features” and then do a full scan with an updated Malwarebytes and your chosen antivirus program.
That’s all for another week, email you questions to email@example.com and I will see what I can do.
