CPU @ 100% in Task Manager.. but in error

Resource monitor is showing a silly % here too. No Intel drivers to download for me as far as I can tell.
This is a clean install, which I was hoping would solve this issue, but it hasn't

I am going to try get ahold of ASrock, it may take them a while to get back to me... I'll let your know...

I have also been getting some BSOD's with DPC Watchdog errors, which seems to be causes by drivers

I did have random freezes (hard reboot required) until I did a fresh install, no BSODs tho. I assume yours is also a fresh install?
I'm tempted to download the 7 drivers and see if they actually install, job for tomorrow...
Asrock are pretty good, I has a BIOS update issue (which was 100% their fault) and they quickly got a BIOS chip with the latest applicable version on it in the post to me.

Nice. Unfortunately for me, a newer BIOS isn't an option, this is part of some correspondence I had with Asrock:
In 2011 there has been a recall for Intel 6-series motherboards. The B2 stepping of the Intel chipset had some bug which was mainly SATA3 related. This was fixed in the B3 stepping of the chipset. The B2 version cannot support Intel ME8 firmware either, which is part of BIOS 3.10 and later BIOS versions.
So your motherboards cannot support BIOS 3.10 or later. The last suitable official BIOS version for your motherboard is 2.00.

Finally i found people with the same issue...

Got exact same problem, task manager keeps show 100%, yet process XP or speedfan give me more... normal reading..

I got 2x Xeon quad core E5410 in a Dell T5400 (if that can help)

Like others i've tried different stuff, from disabling the search indexing to a full system scan, removing unwanted software that have been on my PC for ages but never use (in case it one program not so compatible with windows 10)

So far... nothing...

Welcome to the club :)
Removing/disabling stuff is never going to work because the 100% usage reading isn't real.
Are there any BIOS updates for your T5400 motherboard?
Although a BIOS update appears to fix the issue, I suspect the problem is actually windows 10, since windows 7 and other software report correctly.

Glad to have found this thread. I have an Asrock P67 Extreme 4, B3 stepping with 2600k running at 4.8 GHz.

Same problem, task manager showing 100% utilization across all cores. Resource Monitor is a lag fest, showing same.

I did upgrade from Win 7 64 bit Pro and saw this after upgrade. Using AIDA 64 Extreme, cpu utilization looked normal. Using Afterburner, I used the OSD to display cpu utilization while gaming, all was normal.

After 30 days, Win 10 recieved an update & refused to boot. I tried repair, result was boot image not found.

Clean install, I could not use the SATA floppy drivers from original Asrock install disk, Win 10 kept complaining drivers not signed. Couldn't load those. Upon install completion & reboot into Win 10, I loaded all motherboard drivers from install disk that could be loaded.

Checked task manager, all cores at 100% utilization. Have not had time to check with 3rd party software. On a good note my RAID 0 data drive was recognized and all data intact.

Definite Win 10 / motherboard being 4 years old bug. Everything runs well, no other problems yet. Be great to see fix for this, but motherboard may be EOL'D.

This is not what I was hoping to see. For me it's real, not the ASrock problem. Walk away, and the CPU fan is trying to levitate my laptop.

Ouch! If this was the case, I'd be reinstalling win 7! How old is the laptop?

Sailindawg, did Resource Monitor show some silly high % use, in the millions/billions? Does the 'Details' tab in Task Manager show 'System Idle Process' normal? It does sound like you have the same issue, I've still not fixed it. You might be lucky and a BIOS update works for you as it has others, I'm stuck on the B2 stepping which means I can't upgrade the BIOS

MrPumpkin, what process does task manager say is using the most CPU usage?
