Troubleshooting Hardware Problems

When your computer is acting peculiarly, turn off the computer. Click on the Start button, select the Shut Down option, and then choose Shut Down. Leave the PC off for 1 to 2 minutes. Turn the PC back on again.

An Unresponsive PC

  • First check the cable. Unplug it from the computer and the outlet. Re-plug in both sides and try booting it again.
  • Check the wall outlet. Plug something else into the outlet and see if it works.
  • Turn the system off and wait 30 seconds and then try again.
  • Reach behind the machine and see if you feel air blowing out of the power supply. If you do, then you know the machine is getting some power.
  • Look at the keyboard for the indicator lights being lit up as the machine boots.
  • Sometimes the monitor has something to do with the system acting up. Unplug the power cord from the monitor and the wall and re-plug it. Unplug the cable from the computer to the monitor and re-plug it into the monitor. Try rebooting.
  • Listen to identify a beeping series if there is one to report it to the technical help.
  • Turn in all comments to the Service Desk.

Monitor Troubleshooting

The monitor screen is black

Check to see if the computer turned on.

  • Is the computer turned on? There is a light on the CPU. If the computer is on, it will be lit.

Check to see if the monitor getting power.

  • If no lights appear on the front of the monitor at all, it is not getting any power from the power source. Check to see if ALL plugs are secure.
  • Power cord from the computer to the power strip.
  • Power strip to the wall socket.

Check to see if the Power Strip turned on.

  • There is a light on the strip. If the strip is on, the indictor light will be on.

Check to see if the monitor getting a signal from the computer.

  • There is a light on the monitor. If the monitor is on, it will be lit. If it is turned on, check the contrast and brightness buttons to see if they have been tampered with.
  • A green light on the front of the monitor would indicate that it is getting a signal from the computer.
  • An orange light would indicate there is not signal from the computer. Make sure the computer is on and you see lights on the front of it. Check the cable that runs from the monitor to the computer to see if it has worked loose.

Check to see if the brightness has been turned entirely down.

  • Make sure you check the brightness and contrast buttons or settings on the monitor.

Check to see if the computer in Power Save or Sleep mode.

  • Move the mouse or press any key on the keyboard to see if the computer will "wake-up."

Check to see if all peripherals plugged in.

  • Verify that all cables and cords leading in to and out of your computer to insure they are all in tight and not disconnected.

Secure the following to the computer:

  • Monitor
  • Mouse
  • Keyboard
  • Printer
  • Network cable to computer and wall (Blue)

Check to see if the monitor goes black just as Windows is loaded.

  • This could indicate a problem with the video card driver or settings in Windows. Since you can't see to get to the settings, this is difficult to fix without a visit from technical support.

The screen is not synchronized

  • Check to make sure the signal cable is firmly connected in the socket.
  • Check that the output level matches the input level of your computer.
  • Make sure the signal timing of the computer system is within the specification of the monitor.

The screen is too bright or too dark

  • Check if the Brightness or contrast control is at the appropriate position, not at the maximum or minimum.
  • Check if the specified voltage is applied
  • Check if the signal timing of the computer system is within the specification of the monitor.
  • Especially, check the horizontal frequency.

The screen is shaking

  • Move all objects that emit a magnetic field, such as a motor or transformer, away from the monitor.
  • Check if the specified voltage is applied.
  • Check if the signal timing of the computer system is within the specification of the monitor.

Printer Troubleshooting

The Printer is not printing

  • Check to see if the printer getting power
  • If there are no lights or no display on the front of the printer, the printer is not getting electricity or power. Check to make sure the power cord is plugged in both to the wall or power strip and to the back of the printer. Wiggle the power cord where it plugs into the back of the printer to make sure it is not loose. Some models of desk jets have a two part power cord. In this case, check along the length of the power cord to make sure both parts are plugged in together.
  • If the printer is still not getting power, plug the power cord into a different outlet on the power strip. If this does not work, try plugging the printer into a different wall outlet.

Check to see if you can print a Windows test page

The windows test page is a basic communication test between your computer and the printer. To print a Windows test page:

  • Left mouse-click on the Start button.
  • Go to Settings and then select Printers. Inside the printer window, you should see a small printer icon with the name of printer you are trying to print to.
  • Place your mouse arrow on the small printer icon and right mouse-click. A small gray window should appear and the last choice in the box is Properties.
  • Left mouse-click on Properties. A printer window with several tabs should appear.
  • On the General tab, there is a Print Test Page button in the lower right corner. Left mouse-click on the button. You may click on the "Yes" button on your screen, but the real question is: Did anything print from the printer?
  • If the answer is no, please call or e-mail the Service Desk at x1112.
  • If you can print a Windows test page, try to print from a different program. If the document does not print from that program, the printing problem has to do with that program.

Check to see if there is paper in printer. Is their a paper jam?

  • If the printer has paper in the paper tray, the paper may be jammed or not feeding properly. Take the paper out of the paper tray and check to see that the top piece of paper is not crinkled or bent.
  • If the printer is a DeskJet, lift open the front cover and look to see if a piece of paper is halfway fed through. If it is, remove paper gently from the top and close.
  • If the printer is a LaserJet, open the top of the printer and check for paper underneath the toner cartridge. If there is paper there, gently remove it, and replace the toner cartridge.

Check to see if the computer getting a signal from the printer.

  • The computer and the printer must be communicating before the printer will print. When you send a document to print, does a small printer appear on the Windows taskbar (down by the time)? If this printer appears on the taskbar, the computer thinks the printer is receiving communication. At this point, the printer should blink lights (if a DeskJet) or says "printing" or "receiving" on the display (if a laser printer). If the printer is not receiving the communication from the computer, try restarting the computer. After you have logged in, see if you can print now.

Check to see if Printer offline or Paused.

  • If the printer is off-line or paused, the print jobs will just stack up in the print queue but nothing prints.
  • Left mouse-click on the Start button
  • Go to Settings
  • Then choose Printers
  • The Printer folder should open and display the printers installed on this PC.
  • Place your mouse arrow on the printer you are checking and right mouse click. A dialog box should open.
  • If the printer is paused or offline you will see a black check mark next to the words "Pause Printing" or "Printer Offline."
  • Left mouse-click on the black check mark and see if you can "uncheck" it.
  • If the check mark will not go away, try restarting the PC (Start – Shutdown – Restart).
  • Then repeat steps 1 through 7 again.
  • If the printer is still not printing, please contact the Service Desk at x1112

Check to see if there multiple jobs in the Print queue.

  • If the printer is a local printer (i.e., there is a cable running directly from the printer to the computer you are printing from), power off the PC, power off the printer, count to 10, and then turn both the printer and the computer back on again. Sometimes this will allow the printer to start printing again.

The printer is printing streaks on the page

  • If the printer is a DeskJet, go to the HP DeskJet Utilities menu in the Program menu. Choose the "Clean the Print Cartridges" option. If this does not work, try replacing the ink cartridge. If the new cartridge does not help the streaking, place the cartridge back inside the original packaging and save it until the other cartridge has been used up. This just tests to see if the ink cartridge is defective.
  • If the printer is a LaserJet, try changing the toner cartridge. If the new toner cartridge does not improve the streaking problem, return old cartridge to the printer and place the new toner cartridge back in its original packaging for later use.
  • If neither option works, please visit the printer maintenance vendor list to schedule printer service.

The printer in spite of everything is not printing?

  • Turn the PC off. If the printer is a local printer, i.e., has a direct cable hookup to the PC, turn the printer off also so both the PC and printer are turned off at the same time. After 30 seconds, turn the PC and the printer back on again. Try to print a Windows test page. If the printer still does not print, please contact the Service Desk x1112.

CD Troubleshooting

The computer won't read the CD

Check to see if the label side of the CD is faced up

Check to see if the CD be read from the CD Rom drive of another computer

  • If the CD can be read from another computer's CD ROM drive, the CD ROM drive may be bad and need to be replaced.
  • The CD ROM drive may also have dirt or debris inside. Try cleaning the drive with a standard audio CD player cleaning kit. After cleaning the drive, try to read the CD again.

Check to see if the CD scratched or dirty

  • CD, CDR, or CDRW drives read discs by shining a laser onto the CD and then measuring the amount of light that gets reflected back. Most of the time a small scratch won't matter.
  • If the CD is dirty, you can clean the CD using a CD Cleaning kit or you can also use a mild detergent, like dish soap, and warm water, wash the CD and dry with a soft cloth. Once the CD is fully dry, insert the CD into the CD ROM drive and try to read it.
  • If the CD is not dirty, you can try to clean the CD Rom drive using a professional CD cleaner kit

Check to see if the CD is a CD-R or CD-RW that was burned

  • A number of older CD drives cannot read some types of CD-R CDs. Try using a different CD-R disk with a different dye under the reflective layer. You will have noticed that some CD-R disks are blue, gold, green, or even silver colored. Some of the colors have a lower light reflectivity value and an older CD Rom drive may have difficulty reading that brand of CD-R media.

Keyboard Troubleshooting

Keyboard doesn't respond and gives off a constant beeping noise when booting up

Check the plug to make sure it's connected securely.

  • Try unplugging it and re-plugging it again. If there is no response, check the indicator light on the keyboard. Is it on? Do the lights respond when you press the caps lock or the num lock key? If not, maybe your keyboard is broken.

Check to see if there a key stuck

  • Gently pry off the cover and clean it with alcohol. Make sure it is not connected to your machine when you are cleaning it. The space bar frequently comes off track. Gently pry it off, noting which way the bar lies in your particular keyboard so you can replace it properly.

Mouse Troubleshooting

The mouse is not working

mouse troubleshooting flowchart

 

The mouse is acting erratic

Reboot the computer and see if that corrects the problem. If not check to see if there is insufficient memory.

The mouse will only move one way, either vertically or horizontally

  • Clean the mouse
  • Shut down your machine and unplug your mouse from the computer. Open the underside of the mouse and remove the ball. If the ball is a rubber ball, do not clean it with alcohol. Clean it with a soft cloth. There should be no lubricant placed on a mouse ball. Clean the roller in the body of the mouse with a cotton swab that is slightly damp with alcohol. Replace the ball when the rollers are dry and replace the bottom portion.

Networking Troubleshooting

My PC is not working on the Network

Programs that require network drives to run or operate properly: SIS, HR, FRS, PROD – ALPHA, Network Shares, and some school applications. You would also need a network connection to print to the network laser or color laser printers within CCRI.

Message "No Domain Server Available" or there are no Network drives (like the S drive).
