You won't know

by Jacky Howe In reply to tried passmark..

if the port is fried until you try a known working PS2 keyboard. Normally a keyboard will stop working before a port goes out. You say that it isn't working to enter BIOS, so it probably isn't being detected at post, which is well before the Operating System kicks in.

I will try another kb (usb). if it works its the port or kb that is gone, if it wont work i guess my motherboard is toast...

Have you got a friend

by Jacky Howe In reply to tuesday

close by, that you could borrow, a working PS2 keyboard from. It won't take long to test the port. If it fails, then, you can invest in a USB keyboard.

USB-keyboard works...

by colrouphobic In reply to Have you got a friend

..I don't have a chance to try another ps2 kb on my pc.
In light of the fact that the USB works fine, but my dvd-rom and ps2-kb don't, does anybody know the most likely errors?
Just would like to fix it permanently (as well as possible) but atleast I bought myself some time meanwhile...

OK, check this

by Jacky Howe In reply to USB-keyboard works...

Check to see if it is showing up in the BIOS. If it is not showing up you can remove the cover to check the cable connections.

Remembering to ground yourself, by placing the back of your hand on the Power Supply Unit and not moving your feet. By not taking this precaution it is possible that you could inadvertantly cause damage to the PC from an electrostatic discharge.

Remove and reinsert the cable that is connected to the motherboard end and CD/DVD end.
Do the same with the power connector.

Check the BIOS again, if it's not there it has seen better days.

If it is now showing in the BIOS set it as the first Boot Device, use a bootable CD/DVD to test the Optical drive.

If it Boots it is OK, if not replace the Optical CD/DVD drive.

Edit: missed a bit

Excellent tip, will check it out...

by colrouphobic In reply to OK, check this

Though last time I checked, both showed in the Bios...
If it turns out that they do not show in BIOS, what is it that has "seen its better days"? The keyboard/DVD-driver or the motherboard?
Good to know since I will need to replace whichever then. :) Thank you for all the advice, it is/has been really helpful so far!

LOL

When a reference to 'has seen better days' is used it means that it is of no further use to anyone, "used to describe objects which are worn out". We were discussing the CD/DVD optical drive unit.

The reason for using the Bootable CD/DVD is to see if the laser-lens is still working. They will wear out over time especially if CD/DVD's are left in the caddy and are constantly being read.

You could get yourself a CD drive cleaning kit for tray-based CD players or for caddy and auto feed drives, make sure that you get the right one as they are different.


If you can boot from a CD/DVD drive but it isn't working in windows try this.

Step 1: <b>Start Registry Editor</b>

Click Start, click Run, type regedt32, and then click OK. Registry Editor starts.

5. In the right pane (topic area), click UpperFilters.

Note An UpperFilters.bak registry entry may also appear. To delete the UpperFilters registry entry, you must click UpperFilters and not UpperFilters.bak.

6. On the Edit menu, click Delete.

7. When you receive the following message, click Yes to confirm the deletion of the UpperFilters registry entry:

Are you sure you want to delete this value?

The UpperFilters registry entry is removed from the {4D36E965-E325-11CE-BFC1-08002BE10318} registry subkey.

<i>Note Do not exit Registry Editor. You must have this program for the next step.</i>


Step 3: <b>Delete the LowerFilters registry entry</b>

1. In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.

2. Expand SYSTEM, and then expand CurrentControlSet.

Step 4: Restart the computer

If a CD recording program no longer works after you restart the computer, you must reinstall the CD recording program.

Contact the manufacturer of the CD/DVD Drive to obtain an updated driver for the CD/DVD drive, and then follow the manufacturer?s instructions to install the driver.
