Problem with IRQL blue screen

Qutie the problem. I've checked around for sources of this error and after reading other solutions I've 1) upgraded the drivers on my USB wireless adapter, 2) ran Memtest for 6+ hours (no errors), and 3) checked all of my HDs (no errors). I only get the "IRQL NOT LESS OR EQUAL" error when running Bittorrent; at no other time or when using other P2Ps to test, or when playing games or anything else. The file with the error message is ndis.sys. I think I once got the message with the afd.sys file as well. I also checked my IRQs and the USB didn't seem to be sharing with anything else, so I have no clue how to go about arriving at a solution.

specs:
Athlon 64 3000+
Chaintech VNF4-Ultra mobo
1 gig Patriout PC3200 (512x2)
Maxtor Sata 250GB x3
Netgear WG111v2 USB wireless adapter
Win XP32 Pro
 
I think ndis.sys is a graphics driver file. In my experience, however, that error is related to RAM. When I OC my ram too much/set the timings too low, I get that error. Maybe lower the settings a bit to see if it helps, and if it doesn't, atleast you know it's not the RAM and that I was wrong 🙂
 
I should've added that I have the RAM running at spec, currently. And nothing else is OC'ed as well, so I don't know if running them even slower will help.
 
NDIS.SYS is the file that allows Windows to talk to simpler (sometimes generic) device drivers. If you are getting that error, and it only happens when you are using the wireless connection, it is likely being caused by poorly written, or improperly installed or corrupted drivers for the wireless adapter. Check with Netgear to make sure you have the newest certified drivers for the adapter.
 
AFD.SYS is part of the TCP/IP protocol stack that controls the flow of data. Again, bad drivers are the most likely culprit of the problem since uncontrolled or excessive flow of data from the drivers (or bad data from the drivers) can cause a memory overflow in AFD.SYS that can result in blue screen errors like the ones you are getting.

It is also possible that your Bittorrent client itself is causing these errors by opening too many connections (or invalid connections) at the same time and the Windows networking components can't handle it. This isn't very likely, but I thought I'd mention it just in case reinstalling the wireless drivers don't fix the problem. Reinstalling Bittorrent wouldn't be a bad idea as well.
