Hi,


I have tried to install Oracle database but it was too big for my PC and the installation failed. But it looks like that something has been intalled and the PC has become veeery SLOW.
So the problem is how to remove that **** (sorry) from the computer.

When i try to use Controll panel/ Add Remove programs i don't find anything named Oracle installed, so i can't remove it from there.
When i try to delete the folder Oracle from Programs, i get a message that somethinf is running and that some files cannot be removed.

Then i decided to do system restore trying many points but the restore failed all the time. One guy told me that he had the same problem but he managed to restore system in Safe Mode. When i come to that screen where i should choose how i want to start windows then my keyboard stops working and i can't move betveen the choices. The PC counts down and Win starts as usual.

ok..so i have decided to reinstall the OS but when i put inn the win xp cd i get a message NO EMULATION, hit any key to boot from CD.. but when i hit any key nothing happens an the pc boots as usual... My cd-rom works ok and the cd is in good condition...

The last thing i did to make the pc boot from cd was to pred ESC just after the pc is started. Then i get a message to choose the medium to boot from.. but again, my keyboard stops working and i cannot choose anything!!

Anyone knows how i can fix my PC???? Thanks for advices!

— the thread shows two separate problems that need to be handled in sequence: a partially installed Oracle leaving services/locked files, and a keyboard/BIOS issue that prevents Safe Mode or CD boot. and pointed in useful directions; below is a practical, non-destructive recovery path that walks around the boot-keyboard blockade and removes Oracle leftovers without formatting if possible.

First get a keyboard that the BIOS will see. Try a wired PS/2 keyboard (or a different wired USB keyboard plugged into a rear motherboard port), unplug all other USB devices and wireless receivers, then enter BIOS and enable any “USB legacy/keyboard support” option. The “NO EMULATION” message on the XP CD is normal for many boot disks — the real failure is that the keypress never reaches the BIOS. Solve that first, then set CD/USB first and use F8 for Safe Mode.

Once you can interrupt boot, start with Safe Mode and identify services/handles locking files using a tool such as Process Explorer or Handle (Sysinternals). Stop any services whose names contain “Oracle”, “Ora”, or “TNS” and remove their startup entries. If an Oracle uninstaller exists in the installation tree, use it. If not, in Safe Mode delete the Oracle program folders, remove Oracle-related environment variables from System (PATH, ORACLE_HOME, etc.), and (after a full registry backup) search the registry for “ORACLE” and remove the vendor keys and the corresponding entries under Services (CurrentControlSet\Services) that reference Oracle services.

If files still cannot be deleted, boot from a Linux Live CD or a Windows PE/Hirens-style rescue disk and delete the files offline; you can also mount the registry hives offline to remove stubborn service entries. After cleanup, run chkdsk /f and sfc /scannow to repair system files, then reboot and verify performance. Backup important data before making registry edits; if uncomfortable with manual removal, a repair shop can complete the cleanup or perform a clean reinstall once the keyboard/boot issue is fixed.

Hi,

Check in your task manager, I think that appache server was already installed on your computer, if so try to stop it any way (may be using start>>run>>msconfig>>startup). As for the files I once gut the same problems with the files Oracle places on your disk. Up to my knowledge the only way to do it is to format.

I just discovered Dial-a-Fix after going through the entire 'softwares worth downloading' thread and it fixed the problem I was having. It reloads system dll files. Give it a try.
