mp3s multiply themselves

I have this problem with my Lumia 720. I upload mp3s through the cable, put them on my SD card. At first its fine, but then after few days when I try to access them through the standard mp3 player the song list is doubled. Now I have 2 of every song. I
left it untouched for another few days and they multiplied again, it got to a point where I had 5 copies of each song on the list. And they all work. I have to listen to the same song 5 times or skip the copies to get to next one. I tried to delete the multiplied
copies but then the song stops working and I get error code 80070002. Note that I only get this error code after I delete any of the unwanted copies. Help.

 

W10 can connect to wider internet but cannot access web pages

I have an odd issue with my W10 laptop linked to Sky broadband in the UK via wifi using a Sky router. The effect is that while I can actually access the internet (I can send and receive emails using Outlook and can connect to other machines using TeamViewer) I cannot access any web site (Google, BBC etc). There is no specific error message, merely that the access request timed out and a suggestion that it may be to do with proxy.

I have tried the following:

1. Other systems (W10 and ios) can access web sites using the same Sky router (therefore probably not a router problem)
2. I have sent and received emails using Outlook, so the broadband connection is working (probably not a Sky problem)
3. I have tried two different browsers (Firefox and Edge), no connection (not a browser problem)
4. I am using Windows Defender and have:
   1. Made sure that Firefox is in the list of allowed systems in its Firewall, no connection after a reboot
   2. Turned off the Firewall and tried again - no connection

My next step will be to re-install Windows, but has anyone got any other suggestions? Could it be some sort of virus (I have carried out a complete virus check using Defender)

So - any suggestions?

 

B(lack)SOD after closing GPU demanding applications and games

I would like to suggest 2 more things if you don't mind,
1. Seat the GPU in another slot, if possible, and see if that helps anything
2. Use the GPU in another system, if possible, this is a step to determine that it is really the GPU and not multiple defective slots or something else from the system.
