Windows 10: Performance degrades from 100th percentile to 0th within minutes after clean boot

So I recently bought a laptop for gaming, ASUS ROG GA502. Ryzen 7 3750h, 16GB of ram, 1660Ti, Intel 660p 512GB.

Installed a fresh Windows 10 Pro, 64-bit, (same link as in sidebar), but had issues almost instantenously. Updated Windows and drivers, ran memory tests, scanned for virus/malware, optimized disk, no improvements.

What weirds me out and have stopped me from returning the unit right out, is that right after boot it works well. A couple of minutes later, without any activity, it is out-right unusable, as in not being able to load something like GMail.

Anything obvious that could cause this behaviour? Below are user benchmarks for right after boot and a few minutes later.

Silent boot failure

List your specs out and tell us each step in cleaning you did.

 

Can't Perform Clean Boot

I gave it a go but still no joy unfortunately. Whatever I do it still starts as per original screen shot when it's supposed to be in clean boot.

What I noticed was, even after doing your step 3, (checking 'normal startup' on general tab, and enabling all services 'hide all' box unchecked, and all items in start up enabled) then restarting ....when it boots up (supposedly now in normal mode), if I go into config, the general tab is as following screenshot;

So it seems as if it never actually boots up in 'normal startup' mode to start with, (although at this stage all services in list are ticked and all items in startup are enabled).

But from here, if I go through your procedure from step 1, and just uncheck the 'load startup items' box on general, etc, etc, then when I reboot, it will always be as my original screenshot (with only a small number of services remaining unchecked and the 'hide all' box having unchecked itself). The following screenshot in how it now looks in general tab (so when it's supposed to be in clean boot);

I'm not sure whats going on in that 'load system services box there. It's all quite confusing.

Hi Allen,

So we can further isolate the issue, we suggest that you perform a clean boot
by following the instructions on this link. This link has the step-by-step procedure on how to perform
clean boot in Windows 10.

Keep us updated with the result.
