UTorrent Makes Windows Crash / Freeze


Recommended Posts

When UTorrent is running for more than about 10 mins or so it causes my computer to crash - the screen freezes and the PC needs rebooting. Any help would be appreciated!

The chipset looks like some atheros, from the belkin -> jumpstart service ...

There are no indicators as to what it could be if your drivers for the NIC are updated to current. I'd try uninstalling unnecessary programs one at a time over time to see if the problem goes away. That is unless you want to play with http://slackware.com/torrents/ one night and take out everything in sucession. Things to start with the Uniblue registry booster, synchrosoft H2O, or even that additional VIA monitoring utility. Are you running a RAID for your drives? What about IE, is that your default browser, because 4 processes of it seems.. alot ??

So now it crashes once a day? Or after the day delay it's crashing same as before multiple times / hour. You could always try replacing AV, as AVG sometimes causes its own problems.

Of note, sometimes things not obvious are the result of exploits/trojans, so if you haven't scanned lately... if you'd like something with great detection rates I'd recommend http://www.malwarebytes.org/mbam.php

I am fairly certain the cause is AVG. I have had issues before where uTorrent would give insufficient resource errors when a full system scan was running at the same time as a uTorrent download.

Last night my machine blue screened. Last night I was also running uTorrent and my machine did it's weekly avg scan. I analyzed the minidump file from the crash using windbg (I don't know much when doing this, but enough to get a little info out of it.) The most relevant portion? The crashing process was avgcsrvx.exe. This process is also present in oduffy's process lists.

AVG's product has been bothering me for a while. I think I'm going to remove it (make sure it gets completely removed) and try something else.
