BSOD, Driver_IRQL_NOT_LESS_OR_EQUAL, classpnp.sys - MSI 880GMA E45 MB

I'd second Captain's Jack's post. Since the failing drive is not the OS drive, try disconnecting it and see what happens.

Though with the current price of hard drives, there really is no reason not to get a new one. Here is one the same size: Newegg.com - SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

You can't beat the price!

Thanks for the report, I'm glad it worked for you. Let us know if you need anything else!

Hello,

Try installing these updated Realtek Ethernet drivers: Realtek

If the BSODs persist, enable driver verifier: Driver Verifier - Enable and Disable

Good to hear you've found that.

Have you replaced it yet? Is your system stable?
