Windows XP is famous for the blue screen of death, and the lack of information it gives you about the cause, which can vary greatly.
I suggest you check your system logs in your event viewer. With XP, there is without doubt a huge amount of events recorded, many like the tcpip limit being exceeded are normal when running torrents and can be disregarded, but to simplify things, and considering you have an issue that’s easy to reproduce, I’d recommend clearing all events then checking after your bsod, and see what events are reported.
I also suggest you try running BitComet with windows in Safe-Mode (with network support) and see if it runs stable or not.
Also, since you’ve been able to run another client that is ONLY a bittorrent client without issues, then lets try disabling everything in bitcomet that isn’t bittorrent, and see if it runs stable on your system. It’s very possible that one of the devices your using (or it’s drivers), or some software you have installed is conflicting with some of bitcomet’s advanced technology. Try disabling LTseed, emule plugin, comet ID and all the items under “services”. Also disable dht, peer exchange and peer discovery.
Disable these all as a test only. Features like LTseed are what makes bitcomet superior when downloading public torrents, so hopefully we can get them all working, but if disabling these stops the bsod problem, then enable them one at a time until you find the one that triggers the bsod.
I’d also consider completely uninstalling that relieance netconnect device. It obviously has serious issues with stability so I’d remove it completely until this issue is resolved, then you can work on getting it to run after your system is stable.
One additional technique I use to diagnose these things is to install another copy of your windows operating system on a different partition, then install bitcomet on it so you can eliminate the cause being a problem with your current windows operating system, such as corrupt files (damaged) or incompatible drivers, etc.
Many users prefer to just do a reformat when they get BSOD errors. Most repair shops do the same thing, as it’s easier to do this then to troubleshoot the cause. It’s also much easier to estimate the cost to repair if they know exactly what they need to do. I prefer to actually fix things, but if you want a sure solution, then reformatting is a good option.
