I just installed a new SATA/Raid port into my HP a220n and connected a HP DVD 1070i. When I booted the system the first time after installing the port, Windows booted fine and detected the port. After I finished installing the drivers for the SATA port, I turned off the system and attached the DVD Burner to the port and rebooted the system. 1st few times the computer powered on but the screen stayed black. Finally windows started but runs very slow and freezes soon after booting. I tried installing 1 GB of DDR ram but windows still crashes. I removed the hardware deleted the drivers and started over, repeating the same steps as before. Again, computer freezes after DVD drive is installed. Any suggestions?

Sounds like your new controller card doesn't support SATA DVD drive. Check the specs. Why did you buy a SATA burner if you didn't have SATA ports? IDE ATA/ATAPI drives are still available and there is no advantage to the SATA interface.

I bought a SATA RAID 2 Port PCI Host and a HP dvd 1070i. I'm not totally knowledgable about computer hardware and was originally looking for a USB 2.0 external drive, but was talked into the SATA port and drive by the salesperson at CompUSA who claimed SATA was better for lightscribe cababilities, a feature that I was looking for. Anyway, I checked the specs of the controller card but nothing about DVD drives specifically, it does say that it supports all windows drivers for XP. When the computer is working (like right now), windows reports both the controller and the drive as "working properly" and all driver's are current. If I try to use the drive however, windows freezes up. Do you think the problem could be the new RAM I installed?

Give the specs on your computer.
