znutar Posted June 19, 2007 Report Share Posted June 19, 2007 I have an unusual problem that I have not seen mentioned in the forums. Recently, when I run utorrent, the system process (not system.exe the trojan, but the actual windows system process), eats anywhere from 50-80% of my cpu cycles when utorrent in on. This is not related to the avast P2P shield and I have shut down other non-essential processes to see if they are the issue and they are not.This problem also manifests when I am web browsing and trying to watch some types of inline video files, often flash based. However, even when the browser is shut down and only utorrent is running, I still have the issue with the system processs chewing up cpu cycles. There are a ton of dlls associated with this process and it is essential and can't be turned off. BTW, utorrent seems to use anywhere from 8-20% of the cpu cycles during a session, which seems a bit high...Anyway, my system is a Compaq, AMD turion 64 notebook (1.8 GHz) with 1.25 Gb of ram.Any help would be appreciated.

Firon Posted June 19, 2007 Report Share Posted June 19, 2007 Check your hard drive controller. Ensure it's set to UDMA. If it's PIO, that'll cause serious CPU issues. Link to comment Share on other sites More sharing options...
znutar Posted June 19, 2007 Author Report Share Posted June 19, 2007 yup, checked that.... UDMA mode 5 for the hard drive Link to comment Share on other sites More sharing options...

znutar Posted June 19, 2007 Author Report Share Posted June 19, 2007 yeah, I turned the P2P shield off and it had no benefit at all, still grinding away. Link to comment Share on other sites More sharing options...
Switeck Posted June 20, 2007 Report Share Posted June 20, 2007 Get Process Explorer and see what's going on in the background.If you post a process list of what's running on your computer, we may be able to spot possible problems. Link to comment Share on other sites More sharing options...

znutar Posted June 25, 2007 Author Report Share Posted June 25, 2007 shutting down none of those processes made a bit of difference, instead I'd did a large scale, global repair of windows...not via recovery console, but the version that replaces all your system files but is non-destructive so you retain your setting....that seems to have fixed the problems, so I guess it was likely a slightly corrupted system file.
