My USB devices, mainly my headset and wireless adapter keep disconnecting, when I looked at device manager they appear to have a yellow exclamation mark. I have uninstalled and installed their drivers several times and still no luck.

If I take the PC apart what should I be looking for?

You don`t need to take the computer apart.
what you are seeing are too many drivers, or other hardware wishing to use what we call an Irq.

Or Interrupt request.
Every bit of hardware with its driver should be assigned it`s own Irq number.

It is given by the mobo so each device via its driver can request data through the cpu of the system you have or via the cpu access system memory.

When you have a yellow exclamation mark next to your driver it means the board cannot allocate a Irq for a bit of hardware or what the driver can, or is requesting for the device to work.

You should check for a later version of the motherboard chip set driver, in your case.

A tip here is also to enter your bios of your motherboard.
Any Interface you...

A tip here is also to enter your bios of your motherboard.
Any Interface you do not use should be disabled/ turned off.

Examples are:
Floppy drives/ and the controller.
Serial port devices, and parallel /com ports.
Midi ports.

If the board supports Sata, but also has a connector for the old style 40 pin block for HDD`s and Cd rom drives.

Disable the IDE selection along with smart mode ect, if you know you have all Sata connected device to the mobo.

This will free up Irq numbers since the resource is turned off and you will have free Irq`s.
That can be assigned via windows and drivers of the hardware you have.

If you get too many devices at the same time Requiring the same IRQ number from the board it`s why drivers fail or you loose the device in windows, marked with a yellow exclamation mark.

Give it a try.

Your other option is to set the way Irq`s are assigned by changing the setting in the bios from auto to manual.
That will force hardware to shuffle Irq`s and may solve the problem also.
