Greetings,
Thanks for adding your system parameters. I can now better visualise your system.
Can you expand as two how your system when from "it is running fine.." in your second last post to the boot and shutdown anomalies you posted in your last post. Did you make any change to your system configuration or the BIOS or windows settings?
Have you disabled RAID and selected IDE as interface? Does your Seagate hardrive need a firmware update?
Have you disabled all power savings and sleep options in both BIOS and Windows?
Are you still running with onboard graphics or are you using your PCIe video Card?
Remember that your posts are our insights into your system. In future posts try to be as specific as possible. For Example: I have not made any changes to my hardware config or BIOS settings but I now have new problems. My computer now .... or I changed BIOS setting X and Y... and Connected my video card...and..
In summary many things could be causing the new sympthoms you described. We need to assert your config and settings first before being able to take pertinent corrective action(s). Take a few moment to answer above questions.
Meanwhile, double check your speaker connection on the motherboard, confirm both proper insertion and polarity.
