DVD ROM DONT READ DVDs MOST OF THE TIMES

i am using windows 7 32bit ultimate. since i have clean installed windows 7 mt dvd rom dont read dvds most of the time. i have tried reunstalling it using device manager even i have deleted the filters entry in the registry but still it doesnt work. i am having TSST corp CDDVDW TS-L633L.
can any one give me the solution of this or provide me the drivers so i can reinstall it using drivers.

What exactly does your drive have trouble reading?

Is it DVD Movie's, Data DVD, CD's?
Could it be a codec problem?

Can you please tell us about your system to see what were working with?

Thank you.

i am using Hp pavillion dv5 1050ei core 2 duo 3gb ram. 2GHz windows 7 32 bit ultimate.

doesnt matter i play data dvd or movie dvd it happens same thing. when i insert the disk after few seconds i can hear the sound it start reading then stop, start and stop. this only happens all the time. some times it works but most of the time it dont.

When you installed windows 7 did it install the drivers for the drive. Check by clicking Start, Control Panel, Hardware and Sound, Device Manager and check for red crosses and yellow exclumtion marks or unknown devices there shouldn't be any.

Yes do this and also check to see if you have a drive letter assigned for the drive.

If everything checks out you may need a CD/DVD drive cleaning kit. And if cleaning still doesn't help, it may be time for a new drive.

i checked this and there is no such sign or symbol. there must be some solution for this except changing the driver because i was before using vista and never faced such problem. only last months i installed 7 on my laptop and since then i am facing this problem.

What type of drive is it. is it SATA or IDE and check to see if the cables or firmly connected to the mobo and the drive.

Coco it's a Laptop that connects directly to the board.
