|Have a system with a 10yr old motherboard, to which I added a PCI card for USB 2.0. I keep getting system freezes and blue screens whenever I deal with USB flash drives plugged into this card. |
Today, I wanted to transfer a folder of graphics files onto one of the flash drives, and plugging it in, I saw a msg,,"USB device not recognized,,,". I tried a few things, but ended up with a blue screen, telling me to restart, and to follow some instructions if it happens again. (Drivers, BIOS updates, disable caching or shadowing, then a bunch of numbers, after the word "STOP" (memory locations?)
The last thing on the blue screen was some notification that it was doing a dump of physical memory, and to contact "tech support".
I've heard this word "dump" before, on another thread, and wondered where it is,,(more later on this)
Restarted, tried installing again, with another USB drive, and the same thing happened, so I suspected the card, and not the drives. This card has been giving me troubles.
I got another blue screen sometime during the troubleshooting process, which also included "BUG CODE_USB_DRIVER", and more memory addresses.
Then I removed all USB drives, and tried to check the device mgr for USB devices, and it wouldn't open. (or maybe my system was just doing its "slow" thing).
Finally, I decided to restart, which gave me access to the device mgr.
Something called "NEC PCI to USB Open Host Controller" had a yellow ! on it, so I uninstalled that, and restarted again.
Then, I was able to make the drive work, and transferred the files.
I then decided to defrag, since I hadn't done so in a long while.
I ran a chk disk on restart, and a message came up saying that a serious problem had occurred, and would I like to send a report to MSoft. I declined, but took down the info.
In the report, there was a reference to a .dmp file called "Mini01131301.dmp", and the location on my hard drive. There was also a reference to an "xml" file called "sysdata.xml", again, at a particular location on the HDD. These two files were named "error report files".
I'm wondering what to do with the .dmp file in specific, since someone here told me I should look for it, that it would offer clues to what's going on.
thanks for helping
