Issues in Intel DG41RQ motherboard

Hi guys, two days ago i bought new Intel DG41RQ for my rig, i used Dualcore E5200, SBlive 5.1 Soundcard, 1 x SATA DVDRW (H73-GSN) and 1 x IDE CDRW (Sony) with this mobo. i preferd to use the onboard video to save my budget.

The issues that i am facing are as follow:

1 - booting with SATA DVD-RW is too difficult, it always shows error like "file not found", (my DVDRW is working perfectly).
After installation of OS (windows XP SP3) with my CDRW, i use to DVD (came with my mobo) to install drivers. it is taking hours to access the data in DVD (when i tried to install drivers using my DVDRW).

2- i used to onboard Realtek GB Lan, when the system start the LEDs on LAN device show normal behavior, but when the window loads it turns OFF, and both LEDs start to blink with some period. In Windows it says that Network cable is Disconnected. I used a seperate 3Com PCI lan card instead of onboard Lan, it worked like charm.

3- The Motherboard comes with GMA X4500, which has some muscles to run games like COD4 and NFS Most wanted. when ever i run the game the system restarts automatically. The system shows no anamolies while doing any thing else than gaming.

I need to know what is the problem, is this mobo is faulty or the Drivers are not properly released. Does any one else facing such issues.
