8 Core Processor only registers as 1?

[AlexanderFX]

Ok, so I built a pc that I use for graphic design I make 3D models in Cinema 4D, and animate in After Effects. Yesterday morning I got up, and I didn't feel like starting the day with intense activities. So I decided I wanted to play a game on my computer. I got on, and for some reason I get random lag spikes... I was thinking its not possible my computer is lagging in this game. I checked my task manager, and it showed 94% cpu usage. I looked what was taking up that much of my cpu, and it was my game! I was so confused cause I let my little sister use my computer to play the exact game about 3 days before this, and I wasn't in the least laggy. So I go into C4D to model after a while of modeling, and animating the cameras in Cinema 4D. I start rendering the animation in png format, and I only saw a single core working on this. I went to msconfig to see if It can change the processor settings, and it only has 1 core in the drop down. I've tried many things to get this issue fixed I sat on support lines for the longest time seeking help, and they weren't going to do anything for me unless I paid 150$. I've tried 3 different lines, and none seem to work out without any sort of charge this includes Microsoft tech support. I would greatly appreciate some help here I'm doing my best to get this issue fixed as soon as possible because I have due Graphics projects, and I cannot afford to pay 150$ to a tech support line.

Alex,
Have you got a restore point prior to your sisters playing on the comp.
If so use it, and make a note of which program will be changed, then youll know what she changed.

see screenshot to amend processor count

I used the computer after her, and it worked liked its should then, but as soon as I turned it on yesterday it did this :/

 

[torchwood]

see my edit

 

[AlexanderFX]

I did that, and that where it shows a single processor. You can see this in my Screen shot

It shows always "1" - this is not unusual, just confusing. Here is my quad core:

 

[AlexanderFX]

I even have the box checked, My cpu and motherboard drivers are up to date. I've uninstalled all my cores, and then re-installed them. I have no idea what to do...

If you "need" to check that everything is working correctly with your multi-core processor you will need a more specific tool - the one I recommend is freeware HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information, Analysis and Monitoring Tools which will show a lot of info on the processor and everything else on your PC. (for some reason this program will often offer to upgrade the program, on start up, to the latest version even when you are running the latest - this can be ignored, the program is fine)

I think I want to restore my pc to Wednesday I will check this stuff out though

There is nothing you need to do. You worry about a red herring.

Hi,
Yep seems a normal boot to me on quad or 6 core intel cpu :/

Have you checked your power plan or saved desktop theme to see if it's changed ?
Most people would use a performance power plan and keep boot as normal
Go to control panel and power plan to see what it's set on switch to performance and see how it goes the system should adjust to needs automatically if not you might have an issue but I doubt it's with the boot options.

 

[LMiller7]

In the advanced boot options dialog the number shown for "Number of Processors" will always be 1 by default, regardless of the number you actually have. With the checkbox unchecked which is the default condition it will use all available cores. If the box is checked it will limit the cores to the number shown. In post #7 the box is checked which will limit the cores to 1. The box should be unchecked except for diagnostic and testing purposes, not normal use.

 

[wasnotwas]

How many cores does the OP see in Task Manager - Performance ? Should look like this (ignore cpu 100% - I'm rendering ATM)

 

[Layback Bear]

As LMiller7 has stated. Remove the check mark from Number of Processors.

It should look like the picture in whs post #6. NO check marks.

 

[Barman58]

It should also give the option of 1 to 8 cores with the option ticked - which it appears not to do - which would indicate that there is an issue as also indicated by the program that initially brought this to the OP's attention

 

[VsUK]

Has your settings changed in BOIS settings? But I think your board has UEFI. This happened to me once & for some reason the multi core cpu support was disabled so I only was using the 1. So simply enable it & leave the cores 1-8 left on auto & when you exit, will immediately switch off then back on again & your core's should be restored. That is, if this is the problem you have. But I've never come across missing cores unless its a failing cpu! But I have the exact same CPU & mine runs great!

 

[torchwood]

Agree with the Barman thats why i posted the screenshot, Even my dual core option is not greyed out.

Roy

 

[Barman58]

I have a similar 4GHz 8350 and mine shows all eight cores as selectable options in the drop-down, which is why I assume all in the series should show the same

 

[whs]

It will show "1" - regardless of what you do.

 

[torchwood]

Mine must be defective then.
