windows 7 strange softlocking

[AlignedManatee]

My windows 7 PC is having a strange softlock scenario where only default windows programs will open and any other program will get stuck in the background as a running process and unable to even be killed with task manager.

 

The PC is usable for 2 minutes where in that time you can get whatever you want to run, but then programs will do nothing while windows remains running and able to open default programs like windows explorer to browse files.

The exception is chrome which will softlock crash and I can kill the process, but not open chrome again afterwards.

 

There are no beeps to indicate a hardware problem, the pc doesn't shut down and component temperatures are well below maximum. GPU idles around 55c CPU idles around 30c 

 

Certain programs like my razer synapse updater will get stuck at 0% a game client I use for an online game stays at 0 also with no error message yet if it couldn't connect to the internet then it would tell me it can't connect.

Sounds like a programs priority has gotten bumped up, have you raised/lowered the priority of any programs?

Otherwise all i can think of is a virus.

Chrome seemed to of set itself below normal so I put it back up to normal but that hasn't fixed the problem.

I have a full scan going with MSE currently to see if that will pick up anything.

Do a full scan with Malarebytes (MSE is a joke, honestly), then see what comes up.

now doing a full scan with malwarebytes

finally finished scanning and it came up with 50 PUP.optional things all related to google chrome which I have now deleted but it hasn't fixed the problem even after restarting.
