Try a good cd lens cleaner they work well may solve it.
If your winXP check your registry under: HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}]
if there is a string labeled either UpperFilters or LowerFilters.
If either of these mention "PxHelp20.sys" remove it. You should see
results almost instantly.
Another way to look for this is to go into device manager and look
at the properties for the drive in question. In the driver tab see if
that file is mentioned.
If you have vista it might be the same, but if not try running a search in your registry for this file.
cd drives have 2 different eyes one for the dvd and 1 for cd,im guessing that your cd is not being picked up by the cd palyer. because theoptical eye for cd is not working i would try another cd/dvd player..ive seen this many times and it usually ends up being the cd eye has malfunctioned.

Since the problem first appeared, she has installed several software downloads, and I recently upgraded the machine from Win 98SE to Win XP (I had to make a backup copy of the install CD on DVD media to manage that!), but that didn't solve the problem. Checking under Start >Control Panel > System >Hardware >Device Manager shows no yellow triangle and indicates the DVD drive is working properly. I've tried using TWO CD lens cleaners, to no avail - the machine still reads DVDs but no CDs.
I don't think we have, yet, but I don't see the relevance, since we're not having problems with DVDs, and the problem started when she had 98SE on the machine
The UpperFilters and LowerFilters strings are not present under that registry item, nor does the file PxHelp20.sys exist on the computer. I ran the HP/Compaq diagnostics; the CD drive tests work fine when there's a DVD in the system, but with a CD they report no media present.
System ROM has been updated to the latest available version, also.
You may well be right. Today I did a search on the specific rebadged Toshiba drive model with the result that it is a known problem with the particular model - and a suggested cure has been posted elsewhere on this site, involving tweaking an internal potentiometer on the drive. Since replacing the drive is impractical at this time, I'll give that a try.
Tweaking the pot controlling the CD read "eye" did the trick. CDs are now being detected and read properly.
This turned out to be a hardware issue - the sensitivity of the CD detector needed adjustment.
Did you download and install the WinDVD Player Version 1.4, 2.4, or 3.0. update for customers who have upgraded one of the Compaq EVO notebook models to Windows XP?http://h20000.www2.hp.com/bizsupport/Tec...
Have you installed any new software lately? If yes, what was installed? Have you changed or upgraded operating systems? Go to Start >Control Panel > System >Device Manager. Look to see if there are any yellow triangles.
