Netvista POST/boot problem

weak battery of voltage drain in the morning take the cable loose look for a tiny spark when you lift the cable end and touch the post repeated ly no tiny sprk key off ? get a battery from something else put in see if it runs down over nite if ? it dosnt maybe time to buy battery

If the ignition switch is jammed, and you cannot free it by moving the steering wheel back and forth while trying the ignition switch, simply replace the ignition switch tumbler and lock assembly with a new one. Before going to the trouble of replacing the entire ignition switch, try squiring a moderate amount of WD-40 or other light penetrating oil into the ignition switch key hole, let it sit overnight, then try again the next morning. Often, that will clear the issue.

Im sorry about your situation.

Does the computer turn on??
If the computer turns on do you hear or can you see the fan working??

If the computer turns on does it stay on or does it shut down after a few minutes??

This will help us determine what is going on.

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

In the morning, turn key to on position for 5 seconds. Do not crank.Then turn off for 5 seconds. Repeat this about 5 times. Then try to start. If engine starts right up, the fuel pump check valve is bad. Meaning all fuel in fuel line is returning to the tank when car sits overnight. The only fix is to replace fuel pump. If that doesn't work, replace coolant temp. sensor for the computer. About a 12.00 part.

Sounds to me like the fan relay stuck on in the first place. Are you sure that the coolant is getting warm enough to turn on the fan? Most cars don't turn on the fan till the coolant gets to 226 F. You might want to change the sensor if this is the case. Sometimes the sensor wont read high temp's. We know the relay and the computer are working now because the fan comes on when you unplug the sensor.
Post back if you need to know more about the system.
Have a nice day!!

Take the SUV to an autoparts store that features free charging diagnostic tests. They will determine if the alternator is putting out sufficient power to recharge your battery. There's also a very good chance your battery is dead. It's not uncommon for a battery to need replacing (especially in a truck with all the bells and whistles I'm sure the Santa Fe has) after 4-5 years. It's also important to ensure there's no corrosion around the battery posts/cables (will have a white or green powdery appearance). Corrosion would prevent the battery from accepting a full charge.

I hope this clarifies your problem. It's unlikely the alarm system is the culprit provided it's not "going off" all day long. Best of luck and please feel free to post back with any other questions.

replace thermostat

just run scandisk for your windows driver and check for any errors.

i once got this problem i just ran scandisk and some errors are found in the filesystem and they were removed
after that i have no prob shutting down my pc.

and if possible try to run a virus scan like avast or avg. etc.., this could take long if you have a monster harddrive and data.

hope this helps..

Try shut down for overnight and turn back on next day. I had same problem - cooling air duct was blocked by ice
