This sounds like the dreaded Windows Vista Black Screen of Death (KSOD). you might have a bad hard drive, but even more likely some software or a driver is causing a problem and caused Vista to get stuck. The repair will not work. You might be able to run a complete repair from the Windows Vista CD, if you have one. If you are not too experienced, take it to a reputable computer service center. If you are at all technical and have time, google your problem and you will see thousands of similar users with same problems.

This is one reason Microsoft released Windows 7 so soon.

MFC-490CW Won't print black


We are going to attempt to do a "power purge" to get rid of any clogged ink nozzles. Note, this will probably eat up about half of your ink, but that is the price you must pay in order to attempt to fix this bad boy.

1) Get into maintenance mode. Press these keys: Menu -> Black Start -> Scan x4 (hit it four times). A number pad should come up. If not, do it again.

2) Hit key 7, then key 6.

3) Press the right key until you get to "CLEANING BLACK."

4) Press 3.

5) Press Black Start.

After it purges and gets back to the main maintenance screen, press keys 9 and 9.

Let your printer start back up. If this does not work, try the above steps up to three times. If it does not work then, you need a new print head, which is not a user-replaceable part on this model.

Good luck.

HP Laserjet 1300 yellow light STILL flashing


Re-installing the print driver will not solve a flashing light. If the printer is functionally ok, it will come to ready simply by plugging into the wall. It sounds to me like a fatal error at this point.....could be a long list of things, but I would lean towards a formatter board. bottom line with this printer at this point in it's life is, if it doesn't work, it's not worth fixing. Replaceable for about $100.

Well my router has all the lights light up accept the wireless light how can i fix that without messing up all the other connections?


Type in 192.168.0.1 OR 192.168.1.1 OR 192.168.2.1. Whichever works.

If none of the IPs work above, go to Start > All Programs > Accessories > Command Prompt (Start > Search: cmd if Windows Vista. Make sure to right click and run as Administrator)

When the black box comes up on the screen, type in ipconfig and press enter. Type in the Default Gateway into your web browser.

You should be directed to your router configuration page. Look for any options such as Wireless, or anything similar. Make sure it is enabled, and mark down your network key.

Scanner & black pages


The black printing usualy occurs when there is a faillure in the light, since your light is working fine, there may be a problem in the imaging device inside(camera) or the reflector. There is nothing wrong with the cartridge.
