Windows 10: Computer is suddenly really slow, and I have no clue why

I was watching Netflix, not really paying attention to my computer. Suddenly it powers off, no clue why, thought it was a overheat which I later found out no. Booted it back up, powered off again whenever I opened Opera GX. Opened it up again, the third time it didn't power off again, but since then it has been literally unusable. Games I could run more than perfectly before are literally unplayable. It takes seconds to type a word, sites don't load quickly, apps don't load quickly. Looking at task manager everything is normal. It's almost like my computer is running at 100% CPU and GPU at a

COMPUTER SUDDENLY SLOW

Hello-

In the last two days my computer is suddenly displaying the message 'low memory.' It has been fine over many months with zero hold ups even with multiple tabs open. I know when I just have too many tabs open slowing things down, vs a certain certain shopping websites

I ran Microsoft Security Essentials, Malwarebytes and disk check / scan last night -all with no change.

Suggestions?

Lenovo laptop suddenly slow

I have a new Lenovo E580 laptop (bought January 2019) which suddenly started to run very slow. I have especially noticed it with build times in Visual Studio and loading times for a local website in IIS.

I have tried to reinstall Windows 10 Pro by formatting the entire computer but it’s still slow.

Laptop spec:

• Windows 10 Pro 64-bit
  
• CPU: i7-8550U 2.00GHz
  
• 16 GB RAM
  
• 512 SSD
  

Software where I really notice the slowness:

• Visual Studio Community 2019 Version 16.3.9
  
• IIS to Windows 10
  

I have tried to setup an older laptop with the same software installed as the new laptop, to compare the loading times. The old laptop has a very similar spec. (i7-4700MQ 2.40GHz, 16GB RAM, 256 SSD). The load time for a local website on the new laptop is 78 seconds where on the old is 30 seconds. On the new laptop it used to be around 30 seconds as well.

It’s not just Visual Studio and IIS that is slow it’s the entire laptop. I thought it would be fixed by reinstalling Windows but there were no improvements. I suspect it’s a hardware issue, but I don’t get any errors, and everything looks fine.

Does anyone have suggestions to what I can try to pinpoint this issue or is it better to contact Lenovo support, as the new laptop is still under warranty?
