joep84 Posted January 12, 2007 Report Share Posted January 12, 2007 Hello,Sometimes when i use µtorrent, my CPU usage goes through the roof, I have read in the FAQ that this can happen with Norton, McAfee and other firewalls, but i don't use any of them. I have tried to solve it with the tips that were giving, but it stills happens. It seems only to happen when i try to download a big file (more than 1GB), i have no problems with albums. Who could help me out? If it stays this way I'll have to start using another bittorrent client, which would be a shame cause I like µtorrent.

DreadWingKnight Posted January 12, 2007 Report Share Posted January 12, 2007 This sort of behavior also occurs when a drive has lapsed into PIO mode. Link to comment Share on other sites More sharing options...
Sun Guru Posted January 13, 2007 Report Share Posted January 13, 2007 Somtimes when I use Utorrent my computer slows completely down because "System" is using all of my CPU. Why is this happening? Link to comment Share on other sites More sharing options...
Ultima Posted January 13, 2007 Report Share Posted January 13, 2007 Check for incompatible software as listed in the FAQ. Link to comment Share on other sites More sharing options...
Sun Guru Posted January 13, 2007 Report Share Posted January 13, 2007 I have gone through the incompatible list and my anti-virus/firewall is not listed in it. I am using Panda at the moment and I really doubt it that that is causing the problem.I have run both sysinternals process explorer and RATTV3. But I really do not know what to do with that info. I am positive that it IS some sort of software that I have installed because lately my computer freezes and when I turn on my computer it is kept a a black screen for at least one minute. After that the startup continues.But usually when I start the torrents in Utorrent, the CPU that Utorrent uses goes to about 10-15% and the process "System" uses the rest of the CPU.Is there anything that you can tell me what to do , step by step in order to find why "System" is using that much CPU?...EDIT: interesting!!!When I run Utorrent and use Sysinternals, I clicked on the System process and looked at it's properties. In the threads tab I found the processes using all that CPU...and it turn out that EVERY process that is using that CPU is of PANDA. I clicked on Module and look at the tab version.And now something more interesting. When I opened my panda and went to the preferences, I got a warning that I am not the administrator. But uhm, I am the only one on this computer and I am logged on as an administrator....So I am going to uninstall and reinstall that software...I will et you guys know whatever happens next...EDIT2:I have reinstalled my Panda. But it seems that that was not the problem. "System" is still using memory when I turn on Utorrent. Although not as much as it used previously, but now it uses about 20-30% of my CPU.And another question: when I try to change my settings in my anti-virus, I am given a warning that I am not the administrator and that I cannot change the settings. But I AM the administrator of my computer. Any body an idea to that? Link to comment Share on other sites More sharing options...
Switeck Posted January 13, 2007 Report Share Posted January 13, 2007 I've heard about rootkits and viruses changing admin settings on a box, but usually to escalate to admin so they can run without restrictions...not lower them. Link to comment Share on other sites More sharing options...
joep84 Posted January 13, 2007 Author Report Share Posted January 13, 2007 What is PIO mode? I don't think Panda is causing the problem. I think utorrent is just not cooperating well with a lot of antivirus scanners. I don't think you should have to reinstall your anti virus software in order to make a bittorrent prgram work properly. I haven't had any problems with high CPU problems the last couple of days, but i also haven't been downloading large files, so i'm pretty sure that is causing my CPU problems.

Ultima Posted January 15, 2007 Report Share Posted January 15, 2007 Start > Run > devmgmt.mscFor the IDE controllers, check the current transfer modes. Link to comment Share on other sites More sharing options...

Ultima Posted January 16, 2007 Report Share Posted January 16, 2007 Whether any of the current transfer modes are in PIO... Link to comment Share on other sites More sharing options...
joep84 Posted February 2, 2007 Author Report Share Posted February 2, 2007 I have two IDE channels, the first is in PIO mode, the second isn't. Do I need to change this? Is the PIO mode causing the problems? Link to comment Share on other sites More sharing options...
Switeck Posted February 2, 2007 Report Share Posted February 2, 2007 PIO mode *IS* causing the problems. You probably need to go into safe mode and delete ALL hard drives and CD/DVD drives. Then reboot. Link to comment Share on other sites More sharing options...
Ultima Posted February 2, 2007 Report Share Posted February 2, 2007 @joep84: Is it only the current transfer mode that's PIO (whereas the preferred mode is set to some DMA mode)? If so, select DMA in the preferred and reboot. If not, then yeah, try as Switeck suggested. Link to comment Share on other sites More sharing options...
