Question about Computers & Internet

1 Answer

Not working I cleaned out the dust from my dell (older model) desktop. I removed a few cables but replaced them all. I also removed something that I fear may have been the processor. Its tall, sliver, and has ridge like structures. The computer "turns on" but no image appears on the monitor. "n ligh" is yellow/orange. Help?

    Alright, so the memory is in correctly. I have a feeling the problem is with the processor. When i removed it, some of the gold "finger-like" connectors look bent up. I straightened them out. The silverlike structure on top is no longer attached to the chip. Problem?

Hi,

:-) It gud that you cleaned your system. But make sure all the things at place from where you picked up.

While turning ON system. Does it makes some whisle sound?

If it do so please check the RAM( a long chip equal to finger size.). remove it and make sure its properly IN on the slot. Same way check the Processor too. Dont not force to push. All the things are of correct size. If it is on right place it will go very easily.

How to clean a dusty computer


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Most of the maintenance you will do in the course of your desktop PC's life is software-based: adding and removing programs or updating drivers. But from time to time, you may need to clean the inside of your desktop computer. Dust, carpet fibers, hair and smoke can enter the system and clog the cooling fan and other vital components. Close all of your programs and save your work. Click "Start" and "Shut down" to turn off your PC. Then, unplug all of the cables and cords from the back of the tower and move the case to a flat, dry surface where you have room to work. Press and hold the power button for 10 seconds to clear any static electrical charges from the system. Let the computer cool off for a few minutes before opening it. Use a screwdriver to remove the side panel of your PC, if necessary. Different desktop systems have different ways of being opened. Older systems those made around 2000 usually have a few captive screws on the back that hold the side panels in place. Systems made since 2001 or 2002 are usually a lot easier to open and feature a large release button that, when pressed, allows the system to swing open like a book. Have a close look at your desktop computer, or refer to the user manual if you aren't sure how to open it. You don't need to remove both the left and right panel. For low-profile systems that sit horizontally instead of vertically, remove the top panel assembly as Identify the power supply from the inside. You can look at the back of the computer to see where your AC power plugs in, and then just follow the part inside. The power supply has a fan in the back and extends into your system as a large metal box. Hold the compressed air canister upright and spray compressed air around the power supply and fan, using the extended nozzle. Use the compressed air canister to blow dust and debris out of your system, beginning at the power supply and moving toward the outer edges of the computer. Blow the dust clear of the PC completely. Check the side panels for built-up dust, and wipe the panels clean with a dry paper towel. Reattach the side panels or close the PC, and reconnect it to its cables.

Check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490 Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

My printer is a dell A920. In using copy/scan I am getting a black rectangular block appearing both on preview and when I copy. No problems with the printer in ordinary mode.


Have you tried to power cycle the printer first? Just unplug the power cable and the USB cable for 3-5 minutes then plug it back in. Check if that removes the appearing block.

My computer hangs/stop responding expectedly and when i check the processor , it very hot , !!! help me plz ...!!!


Hi,

You can try to disasseble your desktop and check if the processor fan is not working properly. Try to clean accumulated dust and replace it if needed. Also add more fans to decrease temperature inside the system. Do not operate your desktop as possible, it may do further damage to other components of the system.

Hope this helps.

1) How to you open the cpu case to get to the fan, etc. 2) My fan has started making noises......can it be cleaned - or is it likely to need replacement?


Things You'll Need:
  • phillips Screwdriver
  1. Shut down your Dell desktop computer.

  2. Remove all of the power and peripheral cables from your computer. There should be no cables connected to your computer when you attempt to remove the cover and open the case.

  3. Watch for the green "Power" indicator light to dim. This light is on the back of the case near where the power cable plugs in. Your computer will hold onto an excess amount of energy for a few seconds after it is unplugged. You don't want to open your Dell computer case while this light is still lit.

  4. Use a screwdriver to remove the screws holding the side of your Dell desktop computer's case. Set the screws aside.

  5. Use your hands to pull up on the side of the case, separating it from the base of the computer. This will allow you to access the inside of your Dell desktop computer.

Dell 4700 sleep on bootup


ok here's what i can suggest. Two things.
1. Check your power settings by going to the Control Panel and then going to Power Options. Take a look at the power schemes..specifically the option where it says turn of monitor...you can select the "Always On" power scheme....if this doesn't do it...
2. Right click on your desktop and click on Properties. Go to the Screen Savers and verify that the time before the screensaver comes on is not something ridiculous like 1 minute. You can just disable the screensaver if you'd like by selecting "none"..

I'm pretty sure you're dealing with one of those two problems.

My dell dimension 9200 desktop won't boot up. When I turn on the machine it remains in standby mode, ie. the power light is solid amber. I all the fans and drives power up but the computer will not even...


Unplug the unit. Open it and reseat all components you can reach and all cables. Blow all dust from the unit. Try to boot again. If still unresponsive, remove all memory and replace one piece at a time. Attempt to boot with each piece, try all the available memory slots. If still unresponsive your motherboard is probably the culprit and the system needs a technician to look at it.

Dell 5150c shuts down orange flashing light


As a temporary measure, taking the side panel off the dell 5150c stopped it from shutting down, so in my case it was clearly a heat problem, as suggested by previous the poster. The following instructions assume you're comfortable replacing computer hardware components - do at your own risk!

The solution is to buy an 'air duster' and some thermal compound for the CPU heat sink. If your CPU fan doesn't sound healthy (mine didn't), also buy a new one (ca. £20 on ebay: search for G9474 ).

Read the service manual: http://support.dell.com/support/edocs/systems/dim5150C/en/sm/index.htm for details on how to install / remove the fan and heat sink.

Clean out dust from the heat sink with air duster. Remove the fan, and clean or replace (recommended). Also clean the grill in front of the fan. Clean off old thermal compound from the CPU / heat sink and replace with a thin layer of fresh compound. Replace heat sink and side panel and you're done.
