DESCRIPTION
Problem started as i changed my Winbond (or something similar to that [-peep-]-it never realy worked properly) NIC for 3Com 905b-tx. (In that time i did'not know the relation)
My computer started to restart as i wrote. In Event viewer i found something like "error category 102" or "Cdrom had
a bad block". First thing that came to my mind was that my teac "is done", but as i mechanicaly took out 3comNic it worked again properly. So I thought that 3-com is that what is wrong so i changed it with one from my work (a better one:-) exactly 905c-tx. It didn't help so i additionaly found original drivers and some testing software for them but no one was detected to malfunction (and I don't believe two 3com NICs could really get wrong). Then i tested RAM (with Goldmemory and Docmemory) but RAM was also good. I tried to format whole disk, new instalation, new drivers, flashing bios and any bios setting that came to my mind but it did't help. I tried to change my power supply but no change. Strange is that the CDs despite of message "data verification failed" seem to be good (acctualy there was a bad cd but at that time i used really cheap cds..)
I got an anger and took my PC to peaces cleaned it ,controled jumper settings and changed ID cables to new 80pin on both channels and set it again but still no change and i tried also other XP release with SP. It never showed unknown device or any device conflict. Possibly only thing i did't tried yet is to dissable device but not to disconnect-that really couldn't help but could tell something...Oh and i tried other PCI slots of course.
Now i really don' know what to do. Somebody told me that there could be a device conflict despite that XP doesn't show any, but till now i haven't found the way how to change IRQ - this setting is not accessible. I tried something about setting "PNP os installed" in bios, "reseting cofiguration setting" and "enabling flash write"...but none of these setings helped...Help please if you go an idea. Thank you

You've tried everything that I would have, except trying another brand of NIC. You may want to try buying one from Best Buy or CompUSA, something cheap, and if that doesn't fix it just return the card. Much easier to return a card to a store than it is to RMA.

definitely easier to return it.
