Hp pavilion modelp6510f press power switch on top of pc does not light computer fans blow but compute does not turn on


ok th p6000. complete range when they were made had to be recalled as they put the copper expansion pipes ran across the gpu & cpu hence a massive overheat problem. they put copper shims over the cpu & gpu but this worked for a short time but it was inevitable and both units ended up being cooked i had this problem with mine. so if you have tried external monitor with no images it would sound or more likely to be the gpu cooked sorry for the bad news.

My Acer Veriton X480 turns off after few seconds and won't boot.


Have you cleaned it lately? Is it getting sufficent air flow? A few cans of compressed air and a can of Electronic Contact Cleaner spray. If so, I would suggest the PSU may be bad. Reseat the memory mods, Try to reboot. If it starts, LED's blink, then completely powers off, Test the PSU with a multimeter, replace if necessary. Do you get anything on the monitor? Or does it shut down before? Had you done any hardware or software updates/upgrades?

My dell gx260 ligth come green if i turn it on but for a few mins time it turn orange why


Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.

The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.

Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.

Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.

Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)

I hope this helps.

I unplug my pc and put it back after a few hrs then plug it back but there was only a blinking green light it does not turn on or off i tried everything like plug off and plug it on still the same i tried...


check the back of the power supply and make sure the voltage selector is set properly. try to switch it back and forth to the correct voltage. Swap the power cord with the monitor. Switch it on again. If the blinking green still comes up, press and hold the power button for about 5 seconds and see how it goes. If this does not work, disconnect all removable items and cables inside the system including power connection and connect them all and test the system again. Hope this helps

My emachine T1742 desktop will not turn on. When plugged in the power supply's fan turns on, cpu fan doesnt start, both hdd/power led's flicker and pressing power button doesnt power on/off system.


Disconnect all the devices from the computer(tower) including keyboard, mouse, monitor(everything)..even the power cable

Now keep on holding down the power button on the computer tower for 15-30 seconds..

Now release the power button, plug in the power cable, monitor, keyboard, mouse and turn on the computer...

If it works, great!!!

Otherwise, take it for repair..

Stack of computer hp pavilion 1430 just keeps blinking cannot turn on or off


Can you explain what you mean by "stack"? Is this an external RAID array? Is this a software error message you are getting on screen? If on the other hand you are referring to the box that everything else plugs in to that would be the computer, everything attached to it, including the monitor is a peripheral. If it's the computer that has a blinking light on it and won't turn on or off, it must be on for there to be a blinking light... to turn a computer off manually you need to hold down the power button for over 4 seconds to forcibly turn it off.
Disconnect all external devices such as printers, scanners etc. etc. and try turning it on again, if you get the same problem disconnect absolutely everything including the power cable and hold down the power button for 30 seconds (time it as it will seem to take forever) and try again.
Message back if it's not the computer, just a peripheral your having problems with or if you still get the same problem.

HP desktop monitor problem


hi try this ,,,
  1. Ensure the video cable is connected (and connected to the correct video port).
  2. Turn off the monitor using the monitor's power button and then restart the monitor.
  3. Cycle the power on the monitor as follows:
  4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
  5. Unplug the power cord.
  6. Wait 5 seconds.
  7. Plug in the power cord.
  8. Press the power button on the monitor to turn on the monitor. One of two things happens:
    1. The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
    2. The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
    3. Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
      • If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
      • If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
      hope it will work for u .. little_angel
