Need to clean HP s7410n of dust

the top just above the door should be spring fastened or are there screws in the back cover
mine i just pop the top and locate the front face screws to remove the front

it seems to be a typical box PC, so I would try removing the side panel then look for some snaps on the front, and unsnap the front plastic bezel from the unit. (one side snaps, the other side is tabbed in with some plastic hinges that will just open as you pull the snaps back). once the plastic is off you should have access to the plastics inside the face panel.

Hi, you can download a driver here at HP:

http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=us&dlc=en&lc=en&product=1844325&

But you have to select your operating system.

You can also try windows update.

Hope this will help you.

1. Remove all originals from the document feeder tray.
   NOTE: It might be easier to work with the automatic document feeder if the document feeder tray is removed first.
2. Lift the cover of the automatic document feeder. Figure 1: Lifting the ADF cover
3. Lift the lid on the HP all-in-one, and locate the notch near the top right edge of the lid backing. Figure 2: Locating the notch near the lid backing 1 - Notch 2 - Lid backing
4. Place one or two fingers in the notch, as you lower the lid of the HP all-in-one. Keep your fingers in the notch until the lid is almost closed. Figure 3: Inserting fingers into the notch
5. Push against the top of the face plate with your thumb as you pull the bottom away from the right side of the HP all-in-one with your fingers. Use a slight twisting motion to help release the face plate on the right side.
   CAUTION: Do not pull the face plate all the way off yet. There is a plastic catch on the far left inside of the face plate that helps secure the face plate in place. If the face plate is pulled straight off, the plastic catch on the inside of the face plate might be damaged. Figure 4: Releasing the face plate from the right side of the HP all-in-one 1 - Releasing the right side with a slight twisting motion
6. Slide the face plate to the left until the plastic catch on the left side is not touching any part of the HP all-in-one, then pull the face plate away from the device. Figure 5: Removing the face plate from the HP all-in-one 1 - Sliding the face plate to the left 2 - Pulling the face plate away from the HP all-in-one

Cleaning the rollers or separator pad Follow the steps below to clean the rollers or separator pad.

1. Once the face plate of the ADF is removed, use the blue-green handle to lift the pick assembly. Figure 6: Blue/green handle and the pick assembly 1 - Blue-green handle 2 - Pick assembly This allows access to the rollers and the separator pad. Figure 7: The rollers and the separator pad 1 - Rollers 2 - Separator pad
2. Lightly dampen a clean, lint-free cloth with distilled water, then squeeze any excess liquid from the cloth.
3. Use the damp cloth to wipe any residue off of the rollers or the separator pad.
4. If the residue does not come off using distilled water, try using isopropyl (rubbing) alcohol.
5. Use the blue-green handle to lower the pick assembly.

Reattaching the face plate of the ADF Follow the steps below to reattach the face plate to the front of the automatic document feeder.

1. Hook the face plate onto the left side of the HP all-in-one so that the plastic catch on the far left inside of the face plate catches on the notch on the front of the automatic document feeder. Figure 8: Hooking the face plate into the left side of the HP all-in-one 1 - Notch 2 - Plastic catch
2. Line up the right edge of the face plate with the right side of the HP all-in-one, and then press on the right side of the face plate until it snaps securely into place. Figure 9: Snapping the face plate into the right side of the HP all-in-one
3. Place your hands towards the center of the face plate, and press until the center of the face plate snaps into place. You should hear two clicks; one when the left side snaps into place, and one when the right side snaps into place. Figure 10: Finishing re-attaching the face plate
4. Close the cover of the automatic document feeder.
5. If you removed the document feeder tray, reattach it.

When you updated the sound drivers probably were not windows 7 friendly.
You need to do two things first search for an updateed driver for your sound card.
Do a system restore before you upgraded and see if that works?

as mentioned, there are more screws under the spacebar. The only way to safely get the spacebar off is to wedge a flat blade into the front centre of the spacebar and lever it off. If you try to pull or lever it from anywhere else you'll just snap something off it.

How do I clean my Cyclone or Air Companion™?
Lay the fan face up on a flat surface. The front grill should be facing you. Remove the screws from the rear grill. Place a flat-head screwdriver into the gap between the front and rear grills. Pull the front grill towards you, exposing the fan blade. Do not remove the knobs on either side. Then, wipe the blade with a soft, damp cloth. Use a mild detergent if necessary. Be sure not to touch the motor. Click here to download product instruction sheet.

i also have the same problem can you please give me instructions on how to disassemble it? thanks!

Wow, You are asking for a complete disasemmbly. If this is necessary, you have to remove any screws you can find that are connected to the front panel. Usually they are in the top of the set ( you'll find them after removing the mirror panel and mirror ). I wouldn't remove any tubes as the tube convergence would have to be all reset and that would require a cross hair generator. I do hope this has helped in some way, but all I can do is send you my best wishes as I certainaly don't suggest disassembly if there is any other way. Good luck
