Okay, i just rebuilt my computer, now in the device manager, there are 2 exclemation point ( ! ) For my first ( ! ) iit SAYS an unknown device, Intel(R) ICH10R LPC Interface Controller - 3A16. I havn't the slightest idea of what it is. the second ( ! ) is for a communications port 2, and under properties, it says "This device cannot find enough free resources that it can use. (Code 12) If you want to use this device, you will need to disable one of the other devices on this system." Please help me. ive spent the past 28 hours trying to get this thing to work all the way, and I am rapidly slipping down the drain of dimensia.
Specs:
MoBo - Intel Extreme DP45SG
HDD - S-ATA 320 GB Seagate
Processer - Intel 6420 (i think) Duel core @ 2.13 GHz, 1066 FSB
GPU - EVGA GEFORCE GTX 260
RAM - 4 GB of Corsair DDR3 1333 mhz
PSU - 550 watt Coolmax (Model - CX series)
Found this.....

Device Manager displays the following message in the Device Properties dialog box, on the General tab, in the Device Status text box:

This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12)

Diagnosis
Two devices have been assigned the same input/output (I/O) PORTS, the same interrupt, or the same Direct Memory Access channel. The assignment was made by either the basic input/output system (BIOS), the operating system, or a combination of the two.

Resolution
This error message can also appear if the BIOS did not allocate enough resources to the device. You can use Device Manager to determine where the conflict is and disable the conflicting device.
