Sounds like it may be your power supply. Try swapping it for one that you know works being careful to plug everything back as it was.

Hp p6530z desktop will not boot


It could be the monitor. Try a different monitor. Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

Is that a SATA drive? Try plugging it into another desktop computer. You will need to change SECURITY SETTINGS for the users folders in order to access the data. I can help you going as far as possible in this case.

Forgetting that the computer was on, I went to turn it on and shut it off while in sleep mode. The screen won't work.


A monitor does not normally save any states such as sleep. If unplugging the monitor from the power source for ten to twenty minutes and re-plugging it in does not fix the problem check and see if the monitor's menu comes up.
Even in sleep mode, the menu for the monitor should show. If it does, try resetting the monitor to factory default settings. If the menu does not show up, then there is an issue with the monitor.

Thank you for using FixYa

I would try shutting down the computer in the normal way, and turning off the monitor.
Boot up and turn the monitor back on.
If it still doesn't work, then I would check the cables and power plugs and wall plugs.
Check the mouse and keyboard cable and any other cables plugged into the computer.
The next step requires a seperate monitor or laptop.
Try unplugging the monitor and pluging in another monitor. Most laptops have a common
VGA adaptor jack or even an Svideo jack.
If the other monitor does not work, Then take to a qualified technician for repair.
It could be your power supply in the computer or video controller.

I hope this was useful and please comment if this was helpful to you.

Power Green Light Flashing HP Desk Top PC m7250n


During a power outage their is a surge when power come back on the grid (surge can be caused by lighting strikes akso). This surge trips the internal procters inside the power supply to protect the Mother Board, hard drive, processor and fans and any device that pulls wattage from the power supply. Since all these power using devices are trying to pull power at the same time to boot the computer back up one ends up with a loop of surge thrugh the power supply with a protective trip, reset, surge again and trip again. This will continue in this loop as the computer is trying to boot all the devices at one time (Mobo, Hd, processor, cooling fans and other devices). Simoly, more power wattage is being demanded than the protectors will allow at one time causing a protective shutdown followed by a restart followe by a protective shutdown in a continious loop.
The normall sequence for a boot is to boot the board, processor and fans followed by a boot of the hard drive, and other boot devices once the board is energised, NOT all devices at the same time, as this results in an overload and trips the protectors. This protective loop is indicated by the blinking light as the power is turned on and then shut down for protection as the wattage pull is over the demand that the protectors will allow.
Blinking light indictes you are in the protective loop.
SOLUTION: 1. Disconnect the Mother Board connector, with the computer unplugged, this will allow the power supply to reset at maximum wattage upon reboot.
2. Disconnect the Hard Drive power connector and ay boot device power supply cables, this will allow the Mother Board, processors and fans to boot without an overload of the protector inside the power supply.
3. Plug in the computer and the indicator light will be solid green indicating that it is reset and out of the loop.
4. With the computer pluged in and the Power Supply fully energised, plug in the Mother Board. The computer will now boot, and the processor fan will come on and the cooling fans.
5. After computer has rebooted, shut the computer back down and connect the Hard Drive power cable and any other power cablis that were unplugged.
6. Reboot with all cables connected and you are up and running again.

POWER SUPPLIES HAVE AN INDICATOR LIGHT FOR A REASON.
REMBER - BLINKING LIGHT IS AN OVERLOAD OF THE PROTECTORS AND ELLIMINATING THE OVERLOAD SOLVES THE PROBLEM AND THAT THE POWER SUPPLY IS WORKING AND CONVERTING POWER.
NO LIGHT MEANS NO POWER OUTPUT AND THAT INDICATES THE POWER SUPPLY IS NOT FUNCTIONING AND NEEDS REPLACED.

Hope this helps everone with power outages and lightining strikes. It is a rather common problem and can also occure when building a computer and one missmatches the power supply with the board wattage needs. If the board wattage needs are greater than the power supply output you will get stuck in a potective loop eventually. WHEN BUILDING A COMPUTER ALWAYS MAKE SURE THE POWER SUPPLY CAN PRODUCE MORE WATTAGE THAN YOU CAN CONSUME AT THE MAXAMUM LOAD.
Have a great computing experiense.
