Recently I got a new graphics card, a new SSD and win 8.1. But I am stuck with a problem. Very often, may be 2/3 times, on startup the system will freeze. Only available is to move mouse and press Win key to bring up that new Start screen thing and to hide it back. 

From event viewer there is only one  error that is with Source: amdacpusrsvc and the description says: "The description for Event ID 0 from source amdacpusrsvc cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."

Thus said, I am not even sure if I am asking on the correct place, but my guess is that Windows installed some drivers to run and can't get rid of them. I uninstalled drivers with the uninstall utility, tried using both 14.3 and the WHQL, but both yield same result. 

If I am at the wrong place, please, excuse me and direct me to somewhere I can find some help regarding this. My search powers couldn't help me further

I suggest you unisntall your graphics card drivers and do a clean reinstall, and if your using beta drivers then that may be your issue

I have never heard of "amdacpusrsvc" and im sure its not a part of AMD's driver package, do this, search your PC for the file and tell me where its located, because that sounds like it may be adware or some kind of virus.

After 2 days of tinkering, searching and immeasurable amount of restarts, I reached the conclusion - 2 of the auto-updates that Windows made immediately after installing are the cause of problem - KB2884846 and KB2919442. Actually, I am not sure which of the two did it, because I removed them at the same time, but now everything is OK.

Apparently, a small number of systems are having this problem from the KB2919442, which I guess is the actual cause.

I searched about the "amdacpusrsvc" and it is in the extract folder of the 14.3 graphics driver package ( C:\AMD ). Anyway, since removing those updates, event viewer logs no such errors anymore. I would guess they were caused by whatever the updates were messing up.

A virus scan reveals no threats in this file.


edit: As if I cursed myself for saying this stuff, it just happened again..

Hi sorry for digging this thread up, but I can't see how to make a new topic I have the same errors from amdacpusrsvc.exe...what is this?

I am not bluescreening or crashing yet, but I have before with windows 8.1, somehow the AMD drivers ALWAYS get corrupted, and I have to reinstall, PC works fine for a few months, then stuff goes bluescreening again.

But yeah I just noticed these errors and wanna find out what they are.

Firstly, make sure you are virus-malware-FREE.



Never, ever, ever, ever, EVER, let windows automatically download and install gpu (or any) drivers.

Should i say the word "ever" again ?


Close internet connection, uninstall all leftover drivers/ driver software through device manager first.

When you are only left with the microsoft basic vga driver, then clean install whatever catalyst software you want.

If it is supported, it should not fail to install correctly.

If it fails, that means you still have to deal with leftovers before you try again, or you are still letting windows decide for you.


Test and post back.
