My tower will not turn on

Make sure you are set up for correct monitor. If keyboard lights flash and HD beeps, but no picture, you may have an incorrect monitor setup. In BIOS, make sure you are set for proper internal/external video, and be sure to plug into right port.

Hi,
if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .

1. Bad video card 2. Bad video software

To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.

If the light changes to green and back to amber the video port on the tower is bad

Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.

reset the surge protector first!

then investigate the power supply

It may be that the cord you have plugged into the tower either a.) doesn't like the plug in or b.) your going to need to adjust power and voltage settings to the monitor

Pull the power cord out and allow it to reset. If you still have issues you may need to replace your power supply.

If your batter has gone bad (won't hold a charge) then it may not even have enough power to complete a boot up sequence. It will simply shut off from lack of power.

Plug it into an outlet and try booting it up with AC power. If that works, then most likely your battery is NG (no good).

If it acts the same way on AC power, then see if you can borrow another power cord and try it again. If that works, then the converter on your power cord has gone bad and you need a new one of those.

is there check engine sign on ? if so go to the right hand side of the dash and pull a lil blue plug from a dummy green socket only has two wires use a lil wire to complete circuit the check engine sigh will begin to flash a code one short flash is 1 and one long flash is 10 example long long long short short short is 33 if there is more than one code a new series of numbers will begin and start all over automatically most likely its you idle air control valve dealer only part dont buy used 99%of time there burned out good luck

Unplug the tower

Remove the ram and turn the tower on wait till it give you fast beeps. (telling you no RAM)

once that happens shut the system down by unplugging it again

Re-install your RAM and try to boot again

Sounds like it is time to go to best buy with it and ask for a new power supply.

when ur starting the tower and it light are on and ur fan there is no problem with the power supply, i think that u rily need a new motherboard because ur board will not boot on start up..
