for some reason my cpu is always at 100 unless i open task manager, someoine help me, idk what could cause this
 
Well I should think the b250m will have a usb capable bootable uefi bios so try clearing your cmos to restore that functionality. You do know how to clear the cmos?

Also another suggestion. If you have a clever friend who has a bootable windows media pre-prepared for contigencies, if he (or she) would be kind enough to disconnect all the drives from their own system so you could connect your drive and clean it, maybe you could do it that way.

Obviously you need to prevent the malware from copying itself to disks and reinstalling itself.

You said you tried malwarebytes and rogue killer not avast! and tdskiller. Different software. They aren't all the same. Some pick up malware/viruses others don't.

i belieave that function is disabled? im not sure, and no i dont have a friend that would do that for me
 
why's it disabled? You can't boot any utilities or windows setup. Why 'won't' you run avast or tdskiller? The mystery deepens. If you can't do any of that you'll have to take it to a repair shop and probly pay over the odds simply to reinstall windows. Crazy. Read the manual. All you have to do to clear cmos (or realtime clock as they call it in the manual) is 1) read the manual 2)shut down the system and switch off the mains power 3)locate the jumper on the board and move it to the adjacent pins and then move it back again.

i managed to reinstall Windows but the problema is still happening is there a chance that the malware is on the usb?
 
Yes the malware could be copying itself to any drives and copying itself back again. That's why you need a clean pc to create clean bootable media on clean drives. Basically there is no way to test that theory without a clean bootable media from a clean pc to eliminate the malware idea. Ideally what you would do is load some bootable disk management software to completely wipe the partition first and then with a different fresh bootable drive made from a clean system run windows setup.

It could also be hiding in the system memory so you'd also have to power down the system between each step.

Are there still any suspicious processes in Autoruns?

Alternative possible you might have a hardware problem though I don't know off the top of my head what causes 100% cpu usage when idle. I haven't run an intel build recently so I'm not familiar with all the issues on that platform.

You could always try a linux install to see if you're system wil run normally with that to eliminate hw problems, and use it to clean your usb drives as well.

1. Reset your firewall, so everything will be blocked.

2. Uninstall (if you can) all so-called Virus- and Malware- -Scanners. They do not scan. They 'imagine' passively what could be a malicious behaviour, by comparing fixed sets of general side-effects of viruses, worms, trojans and malware in general, known to be possible to possibly be identified in that manner. That manner is named heuristically.

3. Download and install exactly one tool: ClamAV. - Do a full scan and if possible just let it run, without using the machine, also cutoff the network, if possible (after ClamAV has all definitions and actual clones of real-probes of all kinds of malware downloaded to compare every thing that is in reach of your operating-system against it). - Read the assumingly 3-digits and up counting results contained in the report carefully, or - if you say it does not make any difference - just kill everything found. - Then plan a reinstall.

4. If you use Windows 10, you have malware on-board by default. If you use Windows Server, you don't. If you use a regular Windows 10, you have a regular part actively sucking any ressource at-will once the machine goes into idle, due to you not using it right now: That part is called Cortana, a data-mining-application that creates gigabytes of metadata to create a wholesome catalogue of any- and every- -thing that may be different in your use-case versus all other users, to help identify your every move and step. You do this freely. It is a feature. - If you do not like that: Run Windows 10 LTSB 2016 or LTSC 2019 or Windows Server 2016 or Windows Server 2019. Or any other Version before Cortana was implemented. There is no other way.

5. If you use Windows at all. Once the system goes idle, the whole system gets indexed in detail, which effectively has absolutely no positive effect at all. It steals your time, eats your ressources, creates catalogues of Meta-Data that will never be-used to any positive outcome .. at least for you; becuase Microsoft is happy if you still have that problem-reporting and automatical transmission of usage-samples and behaviour-indicators, system-logs and by-default-enabled free-sharing of all that information 'to better the services and experience Microsoft delivers you, by uisng their products. - If you do not want that, you can disable it in some versions and editions. It takes a steep learning curve tackled pragmatically in a unreasonable amount of time and you will have no guarantee that it will stay way. On the contrary if you use windows Updates you have the guarantee, that Microsoft will contain patches via Windows Update and execute them on your machine without your consent, to reset your manually disablement of all those indexing and reporting, services, because it was taught that disabling those is malware-practice. You are the Malware. Happy disabling one more time. Until the next Update. - You have to decide. Microsoft says it is a feature.

6. Do not get even the slightest idea i would use this comment to emphasize hatred against Evil Corp. Microsoft. - I do not. I use their products. I do the extra million miles to keep it in reasonable limits, what happens to my systems. Will you?

7. Start at the top. Back to the beginning. You will read this step-by-step-tutorial, again. This is sarcastic. Because it is reality. I mean it.

Hope it helps?!? Thanks for reading.
 
I wouldn't have guessed it was the gpu driver, but that looks like a new issue. I'm running 430.39 but don't have any high cpu usage, but I updated it anyway. Also the symptoms were eerily similar to a malware infection bit of a wild goose chase but for all we know it could have been both! Maybe it's specific to intel+nvidia platforms. Try updating chipset drivers if the issue persists with latest driver. Or maybe your 8gigs of ram is making it more noticable if windows has to page out all the time! It seems like quite a slow memory speed so all that together makes the performance drop more noticable.

I chose the wording "shortcut to a solution" intentionally; I could have said "shortcut to a possible solution", but that is not the point;

You took the chance of a hit and run on a possibility and reasoned it tightly sealed. It is good to be open to spontaneously constructed ways of going on. It is good to be precise. But it is always as good, when you feel that "Wait, could it be?" and you just trust your instinct. Our brains have far more power than we actually recognize, although it is a main part of our being and existence.

No fear, this won't be a philosophical discussion to jump into any given rabbit hole. Just a "Let me show my respect for that combination of thoughts and the eagerness to formulate A POSSIBLE solution ..." - I think your idea or proposal is totally reasonable and makes sense from any yet given perspective. And even if it is not THE SOLUTION. Whatever!

It is a way of thinking that should happen more often. It is part of actively participating in the process and maybe you hit the nail, point on. Who knows?

Thanks for sharing that insight. Keep the ideas rolling. It is always worth it to follow (even those ideas that to others are) seemingly unconnected trails.
 
hmm well I just gave 430.53 a whirl on battlefront 2 and I got 100% cpu usage for a couple of minutes on startup but that was the game running the prepare shaders for the first time on new driver install after that it was about 80% usage on my fx 4350 @ 1080p dsr with ultra settings on 4k quality directx 11 didn't get any lag so the driver seems to be working for me. On idle my cpu is 2% usage. No evident problem.
 
i believe there is one cuz whenever im idle cpu is 100% and when i open task manager is instantly drops to normal usage, ive ran many malware probrams and it doesnt detetct anything. anyone help me out pls
 
stick with 1 thread. don't spam the forum
ive already formatted the pc problem still happens, also ran many malware scanners, nothing detected, can someone tell me why this is happening, also noticed the red LED on the case is constantly blinking, from my research i believe it has something to do with the disks.
what i dont understand is when i formatted everything with nothing on both disks this LED was still going. someone explain whats happening pls
