I am getting a message "boot device not found" and "please install an operating system on your hard disk." What does this mean. My laptop is only a year and a half old and I can not afford to buy another one.

First, do you have a. DVD/CD insert or USB. You can install a fresh copy if you have this on your computer & if you have the Windows Installation disk. This is under normal conditions or old school repair technique with a Laptop, however I discovered lately that certain Computer Manufacturers have shut the public off purposely from Self-Repair, literally forcing. Yoiu to be at their mercy for repair. I am not talking Rhetoric just stating a fact. If you are under warranty & have not altered your Laptop, you qualify for a free replacement Hard Drive & Windows Operating System, both are seprate replacement items. Call HP Support give the Nomenclature (name, number, model) of your Laptop, they will look up Hard-Drive you need, likewise, will send USB loaded with Windows Operating System, that came with your Lapotop, because you won't boot it, but, install a fresh copy onto new a Hard Drive.

There are many reasons a computer freezes. Windows Operating may need updating, because, this changes the system to current Internet. Protocal. Drivers for Programs may have fallen off, & need updating, your hard drive could be full at its maximum capacity. You could have to many Programs on automatics Start Up when you turn computer on, or you make be giving the computer to many commands at onetime.

I did a Hard Disk check on my computer and the quick test the hard disk passed. But, on the full test, @ 49% it came up with "Hard Disk 1 Full (305)" and then the smart check said "Hard Disk 1 Smart (301)".....so, what does that mean?

If the following error message:

The system has detected that a cooling fan is not operating correctly

Error Code : 9b

is showing up then do below suggestion.

If it is other error message then please write this error message in the next reply and ignore below suggestion.

Perform the Hard reset :

1. Unplug the AC adapter from the notebook PC.
2. Remove the computer from any port replicator or docking station, disconnect cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices.
3. Remove the battery from the notebook battery compartment.
4. Press and hold down the power button for about 1 minute to drain any residual electrical charge from the capacitors that protect the memory.
5. Insert the battery and plug the AC adapter back into the notebook PC, but do not connect any of the peripheral devices.
6. Press the power button to turn the notebook PC back on.
