It would be MUCH appretiated if you could put some time into reading this and helping me out.
I recently upgraded my computer with a a brand new Gigabyte GA-K8NF-9 motherboard, Athlon 64 3000+ and Radeon X800 XL. Previously I had Athlon XP 2400, Radeon 9600, and not sure about the motherboard, though I can look it up if anyone asks for it.
I have 768MB DDR266 RAM and Windows XP Professional installed. I did a clean install of Windows after the upgrade. If anyone needs any other info please don't hesitate to ask me.
Ok, my problem is as follows:
No service packs installed: My modem (Fujitsu FDX310) begins to synchronise. At the exact moment when it does synchronise, I get a BSOD with the following messeges: DRIVER_IRQL_NOT_LESS_OR_EQUAL, and also something about usbohci.sys (0x000000D1).
This happens every single time without fail, and im positive it is the modem synchronisation, because when I stop the modem from synchronising from it's control panel the BSOD never appears. The modem works fine on another computer that I have (Pentium 3 550MHz).
I have formatted and done a clean install of Win XP 5 times, trying to install motherboard drivers first, modem drivers first, various combinations, but it's the same every time.
Service pack 2 installed: Now here's where it gets interesting. If along the line I install service pack 2 weird things start to happen. Initially it seems the problem has been sorted out. The modem synchronises, no BSOD, and I can connect to the internet no problem.
Buuuut. After about 10-15 mins, the internet connection simply dies. I get NO disconnection messeges, the internet connection icon in the taskbar remains and WONT GO AWAY if I try to 'disconnect' it, and the modem synchronisation doesn't seem affected. In fact, If I wasn't connected to the internet I wouldn't have noticed anything, except that in that case the modem would de-synchronise and not ever attempt re-synchronising again.
The weirdest bit is still to come. When this happens, some other things stop functioning as well, for example, pressing Alt-Ctrl-Del fails to load task manager and gives an error window, saying 'Application failed to initialize properly 0xc0000017'. I've also noticed windows messenger and Winamp won't work. Also it won't restart properly from the start menu: instead of getting a whole new screen saying that windows is shutting off, I get a small window saying the same thing, and eventually the screen just goes black and nothing happens. I have a feeling a lot of other weird things happen that I haven't noticed.
The only solution is to restart, when things go back to normal again. Now, again if I prevent the modem from synchronising in the first place using it's control panel, NONE OF THIS WOULD HAPPEN. Alt-Ctrl-Del would work properly indefinitely. When I allow it to synchronise, same stuff happens after 10-15 mins. It seems after the modem synchronises a countdown starts to set off these events!
By the way, when I say 10-15 mins, it's because I haven't bothered to measure exactly how long it takes. I'm not sure if it's a set time at all, it may not be, but it seems to be about the same length.
Sooo, what do you guys make of it? I personally reckon it's something to do with my new hardware configuration (duh) and perhaps irq conflict of some sort? Please please help! I have a nice vanilla cookie for you!
