PC reinstall, new problems

[Skybird]

I have gotten monitor and new HD today, gfx still missing, but not needed anyway, it seems. After installin ghte HD, the system showed stable images onscreen again, and suddenly Acronis was functional again and the updates on external drives were accessible again.

Note to myself: when the monitor occasionally blacks out, needs top be switched of and on again and then works again for some time, it is the - HD. You never stop wondering with computers...

Anyhow, I have in hardware monitor now some yeloow warning triangles.
All four "Intel(R) Core(TM) i5-2500 CPU @ 3.30 GHz" are marked, both "High Definition Audio-Controller" entries, and the single "Intel(R) Management Engine Interface". The message when opening these says that "a driver service was deactivated for this device. Possibly another driver could take over this functionality. (Code 32)" (translated form the German).

I googled, and found many different comments, all pointing at different directions. What it really is, I still do not know.

I tried to reinstall the intel chip drivers that came on the moptherboard DVD, I neve rha dany others. Also installed the Realtake sound driver from this DVD again, also never had any other.

I also checked in service manmagetr for services that currently are marked as "deactivated". There were these entries listed as "deaktiviert":

- DSL Manager
- shared use of internet connection
- Logitech Bluetooth Service
- Media Center Extender Service
- Microsoft.NET Framework NGEN v2.0.50727_X64
- " _X86
- Net.Msmq-List Adapter
- Net.Tcp Adapter
- Net.Tcp Port release service
- Routing and RAS
- Windows Defender

The HD is a WD Blue, 1TB, with 64 MB Cache and 6 MB/sec, was it MB/sec? The old one was a Samsung, 1 TB, 32 MB Cache, 3 MB/sec. Is there an incompatability? I have an Asus P8H67-B3.

Windows Update, and Malwarebyte and Antivir Updates have been run. I tried to use driver reinstall option for CPU1 in hardware manager, but it said the latest version already is installed. I looked in BIOS, but found nothing catching my eye there, it is one of these newer graphical interfaces, I hit defaults in easy setup screen, then switched "balance" to high performance again, and left it to that.

Oh, and I have no sound. The icon for volume control is red-crossed. Going to "problem solving from there", gets me a message that hardwarechnages possibly were not recognised. System says no sound output device is installed.

Clueless. What to do now? Can I safely deactivate and delete the CPU drivers in Hardware Manager, and then have them reinstalled via that option there? I mean it is the CPU, not just some addon. When the CPU has no drivers working for the CPU, isn't the system then dysfunctional?
