With regard to the Laptop Keypad not Working post, I’ve heard of spyware causing  keys to stop working, so a good malware scan might be worth while – my flavour of the month is Malwarebytes – try Googling it and run it on your machine.

Have you checked in the device manager to see if the keyboard is listed? Right-click on My Computer and select Properties, then click on the Hardware tab and click on the Device Manager button. In the list that pops up find the keyboard and double-click on it. A window will pop up with information on the keyboard – check this for errors. It might be worth going to the manufacturers site and downloading the drivers. I’ve also heard of a fresh Windows install curing this problem.

That’s all that I can think of – let me know how you get on.

Declan is having a problem with his PC shutting down while gaming or watching Youtube videos.  

Like most PC problems there could be a gazillion reasons for this, but the most obvious is a graphic card problem, possibly overheating. Open the case on your PC and clear out all of the dust from the inside. Check the fan on the graphics card (if it has one) – the graphics card is what the monitor plugs into – and clean it if necessary. Do the same for the fan on the motherboard and make sure that all vents on the case are clear. Run the machine with the case open to check that the fans are turning. Newer graphics cards have software that allow you to monitor the temperature of the card, so this might be worth looking at.

Download and install the latest drivers for your card – use drivercleaner to uninstall the existing drivers should you decide to reinstall.

It is possible to change the settings for shutdown temperature in the Bios, but this is not recommended.
