Hi recently downloaded a program (driverscann)and(speedup my PC) it gave me a list of drivers that were out of date so I updated and installed them then I used speedup my PC and to optimize my computer it cleaned it from unnecessary things. when i was done it said restart so i did . the when windows started so many errors pop-ed up, it was crashing so I restarted to the best known good working configurations and my computer became more stable, but many programs ended up having missing or corrupted data so i reinstalled the programmes. when i restarted the computer the CD/DVD-ROM in driver manager has the yellow (!) on it so i put the data of the motherboard's CD in a usb to reinstall all the drivers because the computer now can't read cds. The CD/DVD-ROM still has the same problem, I even tried uninstalling it in safe mode but still the same problem. I can open and close the CD drawers, I have 2. the computer can see it and detected after uninstalling it and when it tries to install it it gives me this " Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)". when I went to system information- components- CD-ROM nothing is their. in event viewer-system I get the red error service control manager event 7026, description: the following boot-start or system start driver(s) failed to load: Cdrom. please help me i RAN out of ideas .

system: Microsoft windows xp professional, version 2002,service pack 3.
computer: Intel(R) Pentium(R) 4 CPU 3.00GHZ 3.01GHZ, 1.00GB of RAM. decktop :duel BIOS
the mother-boared is :Gigabyte Pentium(R) 4 titan series- GA-8KNXP XF.
please help me1) NEVER update drivers unless there is a specific need to do so
2) NEVER use registry cleaners

Use system restore to go back to a point before you did all this.In addition to what Allan has stated both those programs have less than stellar reviews on WOT and are known to drop malware....so you might want to run a few scans as well....and optical drives don't need any extra drivers...thank you for replying so quickly
i will scan my computer then I'll try the system restore
I'm hoping you didn;t pay for Speed UpMYPC....No i didn't pay for it, thankgod
unfortunately my computer has no restore point of before the disaster only after, I also scanned my computer and it's clean (I used mcafee and malwarebytes' anti malware) any other ideas please 1) First, does the registry cleaner have an "undo" feature? If so, try that. If that doesn't work:

Let's try a repair install. Boot to your XP CD and choose the SECOND repair option. This will install XP on top of itself and replace all system files with their original versions. After doing the repair install be sure to run Windows Update to reinstall of the security patches and updates. I can't promise this will fix your problem, but there is a reasonable chance it will.By the way, in the future PLEASE use a disk imaging utility on a regular basis. There are a few good FREE such utilities and they are worth their weight in gold. At the very least, download and run ERUNT on a regular basis to backup your registry.thanks, I did a backup of my registry before i cleaned it , so when things went wrong I used the restore backup in its options but it didn't do anything, i still had all the error messages pop-up, and that's when i started widows to the best known good configuration. my computer is now stable and working fine except for the DVD/cd-rom drivers after reinstalling my motherboared utilities.
my DVD/CD drivers are
1) HL-DT-ST-DVDRAM GSA-H44N
2) TOSHIBA DVD-ROM SD-M1612

I'll try your suggestion but I'll have to see if i can boot my computer USING a CD first.You should be able to boot to the CD. The problem with the drive(s) being recognized should only be after the OS loads.Okay I had this program with both my laptops. It isn't the program you using. Specially not Speed up my PC or the restore feature it has would of worked. Your computer has a Smart Trojan Virus. That is what I calling it cause I haven't been able to kill it. There is only 2 ways to temporary repair the damage, and there is only one way to fix the program so it don't happen again or till you get the virus again. The 2 ways to temporary fix the problem are to either system restore to a configuration before you noticed your CD Rom not working. Or 2nd way to completely replace all your CD Rom System Registry Files. Now to prevent it from happening again cause it will I promise you cause this virus is eating away at registry files and virus scan cant find it. Norton and McAfee didn't find them on my computers. You have to reformat your hard drive. If you have your drive partitioned like my laptop is cause Dell and Acer which is what I have, and they have a drive partition and a recovery Partition. You need to have your computer DELETE and install the new partition and reinstall your OS and System Files all over. You need to make your computer basic out of the box fresh installed.thank you all so much for your help i appreciate your time and help
before doing your suggestions I thought I'll look some more at the problem on the internet or driver manufacturer sits, then I looked up missing registry files in drivers HQ and found something so I backed up my system and tried this out:

"coppied from site"
Click Start, click Run, type regedit, and then click OK.
◦On Vista machines, Run is accessible through Accessories.
◦Click the plus sign (+) next to the following folders in the left side of the window pane:
◦HKEY_LOCAL_MACHINE
◦SYSTEM
◦CurrentControlSet
◦Control
◦Class
◦{4D36E965-E325-11CE-BFC1-08002BE10318}
2.Look for any of the following names in the right side of the window pane:
◦UpperFilters
◦LowerFilters
3.If any of the items above are listed, right-click on the item and select Delete.
4.Be sure to restart your computer after you have deleted the files in the registry.
5.Open My Computer (XP) or Computer (Vista) and check to see if your CD or DVD drives have returned.
and guess what, it worked! . my CD and DVD drives are running.
thank you so much for everthing and i learned my lesson the hard way. I will never ever use those programmes againI still think your PC is infected. Go here
Follow the directions, post the three required logs and Evilfantasy or another malware specialist will review them to assure your computer is safe. Don't be lulled into a sense of security because it's working.This is so weird! I've had a very similar problem. Both drives went out with a very similar message showing up in the Device Manager: Windows cannot initialize the driver for this hardware (Code 37)

It happened just after I loaded a OEM copy of Photoshop Elements 7. Which installed fine. I wanted to install another program, but a dialog said I should reboot to run PE.

After rebooting the disk drives wouldn't show up on Computer and wouldn't do more than open and close.

I tried the same proceedure listed by cuteice87 involving the dangerous BUSINESS of deleting two registry items and my disk drives sprang back to life.

Now the question is, why?? Were we both hit by a virus, worm or trojan? or is there some other reason why this cropped up, under very different circumstances. Photoshop Elements 7 was purchased from everythingoutlet.com which seems to be a legit outfit. Any ideas?

I'm running Vista on a Gateway machine which has been running beautifully otherwise.
