Nvidia I/o controller issue

I bought a computer , Hewlitt Packard SFF dc7600 with XP-Pro on it. Upon 1st putting in a DVD I was told by Microsoft screen that appeared that I needed a dvd decoder which led me to a web-page to chose DVD decoders, I chose Nvidia, I dont remeber pying a dime for it and could plaay DVD's for years. But after a systym Restore operation my Device Mgr. showed an exclamation mark next to my non plug and play drivers area saying the device for my Nvidia I/O controller was either missing, corrupt or needed it's drivers updated. I called up Hewlitt Packard Remote Services where the tech proeeded to uninstall the driver and reinstall it. When asked if I could play DVD's I said no and he told me I needed a software program to play DVD's and that my Nvidia I/O controller had nothing to do with me playing DVD's here. I'm really confused now, as for the longest time I was able to play DVD's and since the system restore I cant. Anyvody out there who can help?

Try VLC Media Play. It's a free software and works great for playing movies that require a dvd decoder. Just google it.

Open My Computer and check to see if your CD or DVD drives have returned. You may also want to open Device Manager and verify that the yellow exclamation and error code on the CD or DVD drive is gone.

I have a HP dc7600 SFF. Tried to Install 2 graphics cards no vid


The dc7600 SFF only comes equipped with a 240 watt power supply. I think this may be causing your problems.

I am currently looking for a graphics card for the same comp with the HIS ATI HD 4350 in mind, but the website states that a 300 watt power supply is recommended.

as i can c you have a power suply of 200 wats in your pc (correct me if im not right) the GeForce 9400GT is proved not to use a lot of power. but the problem is that your pc is small and it would not get enough ventilation unless you buy a separate fan try it out
