Dear friend, we need more info so help us help you. Please answer specifically and with detail, use your own verbiage:

• What USB device did you unplug?
• Does unplugging this cause the PC to reboot?
• If so, does the PC shut itself down? Explain the process, does it just snap off or does it go through the shutdown sequence? details...
• How exactly do you connect to the internet? Describe your layout.
• Are you sure you have the right drivers?
• Please post your system specs - os? 32/64bit? Motherboard model number or PC model number etc etc.
• What changed recently with your setup??! <---- !

OK, lets take a look at your device:
1. In device manager, right click the network card (should probably be a yellow triangle or red X) and select properties.
2. Go to details tab
3. Under "device instance ID" Please include the part with the numbers where it says VEN_####&DEV_###.

Lets look for more clues in the event viewer:
1. Right Click My computer
2. go to manage
3. click on the event viewer
4. Look through events in Application and System - browse around and look for anything obvious, pertaining to drivers, network card, windows installer etc etc. Try installing drivers and see what comes up too.

You should also look in:
1. Control Panel > Network Connections
2. What do you see? Screen-shot?

1. i just unplugged a usb to mini usb cable, it wasnt connected to anything at the time
2. yes once in a while this does cause it to turn off
3. it just snaps off, like if i were to pull the plug out of the wall
4. i am wired through a router from a cable modem
5. i am sure it is the correct drivers, it is the same one i used when i reformatted it a few months ago
5. Intel Core 2 Duo E6550 Conroe 2.33GHz LGA 775 65W Dual-Core Processor Model BX80557E6550
Intel BLKDG33FBC LGA 775 Intel G33 ATX Intel Motherboard
ASUS EN8500GT TOP/HTP/256M GeForce 8500 GT 256MB 128-bit GDDR3 PCI Express x16
Western Digital Caviar SE16 WD3200AAKS 320GB 7200 RPM SATA 3.0Gb/s Hard Drive
(2)CORSAIR XMS2 1GB 240-Pin DDR2 SDRAM DDR2 675 (PC2 5400) Desktop Memory Model CM2X1024-5400C4
OS- windows xp home sp3
6. no changes made in anything since reformatting a few months ago

i will get the rest of that info for ya when i get home tonight, thanks again guys

Hmm.. that's tough, it feels like some odd hardware issue... So sometimes you unplug the cable causes the PC to powerdown? If so, I'm suspecting perhaps there's something wrong with your internals - i'm thinking along the lines of the motherboard having a crack, a loose component, loose power cables or even USB connectors, perhaps they're not connected to the motheboard correctly (sometimes the come in single connectors like here USB Header pictures), perhaps a loose screw rattling around?

Does jiggling the USB connection cause this? Perhaps there's something broken there that causes some kind of short? Lets try to recreate the issue - how would i be able replicate the crash? Does using another USB jack cause the same issue? does another USB cable do the same?

This still leaves us with the NIC issue. Again, make sure everything is seated in (may want to re-seat the parts and cables). Touch the case before touching any parts, unplug before working inside.

VEN- 8086
DEV- 0000
and nothing is the screen shot

the PCI Database does not show any device for intel that's x0000 so this leads me to believe that its either a broken NIC or it needs to be re-seated. I could be wrong, but we should be seeing a dev number other than 0000's.

What do you mean by nothing is the sccreen shot?
