Windows 10: Win 10 BSOD after reducing number of CPUs

• Win 10 x64 running in VMware Fusion VM on MacBook Pro w/ 6 physical cores & HT.
• When VM is configured with 5+ CPUs, Windows runs fine.
• When VM is configured with 4 or fewer, BSOD INVALID SYSTEM CONFIG INFO
  • WINLOAD.EFI missing or corrupted
  • Attempt to repair using ISO image fails

OS X 10.15.4, VMware Fusion Pro 11.5.3


Win 10 Enterprise

Version 1703

Build 15063.2108


Any suggestions appreciated, as I need to move this VM to another HW config with fewer physical CPUs.


Thanks!

Laptop starts work slower and shows BSOD

No, there was no minidump file.

After 4th BSOD, I did the following:

• installed last Windows updates,
• replaced Sleep with Hibernate (suggestion from here - Asus Zenbook Crash After Sleep – Kernel Power Event ID 41 | g.fisk ),
• performed Battery Reset - (suggestion from here - The Technologically Inclined Theologian: Zenbook Prime and the Unexpected Shutdown Problem ),
• removed some visual effects, reduced number of programs in autorun and disabled windows search for increasing overall performance.

Hopefully, it will solve the issue. I'll post here if BSOD will happen again.

 

Help with How To Reduce or Control Excessive CPU usage by Service Host Local Service & System

Thank you very much SPIRITX for your suggestions.

I went down the list of "Tips To Improve Windows Performance in Windows 10". By the time I got to number four I had reduce my CPU and Memory down to 2% and 10%. I did it by first getting 7.5GB of storage back when I did a system Clean up of the hard drive.
There were a bunch of unnecessary system Backups, Windows update , log files etc. the next thing was to remove application running in the background starting with Norton Security antivirus. As you suggested this application was a huger of memory like the application
alone is 588 MG itself thus freeing up memory and CPU. After restarting I saw immediately a huge improvement. I proceeded by removing unnecessary programs. All these steps I did it it as an administrator since I had less programs as opposed to user. After
completing step #4, I checked the system performance in Task Manager and saw that my CPU was about 2 or 4& and memory less than 10%. I was happy then. restarted the system and logged in as a user.

Here is the weird part of all these. Task Manager CPU was again high about 80% and memory back over 60%. I then decided to remove a huge memory huger application I had been using "Wondershare Filmora". Bingo. After restarting the system my CPU was less than
10% and Memory about 15%.

Apparently Wondershare application services was always running in the background even though there were days I was not using. I guess it was in the starting of programs during initial logon.

My PC is now running faster and better. I still kept Iolo system Mechanics but disable it, letting Windows defender do its job that by the way is doing very well. Thank you for that suggestion.

I am very grateful to you and your team of experts.

Best Regards.

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?
