HP Laptop keeps turning off randomly

Hello,
So I have a very old HP dv7-2185dx on win7, thats always been good to me, but recently it would jsut randomly turn off. Whats strange is that when I turn it back on, i dont get a message saying that it was forced shut off and want to boot in safe mode kind of thing. Its as if it was properly shut down, but wasnt.

I dont ever move it, so I took out the battery and just have it plugged in all the time. Maybe I thought it was the power cable that made it shut off randomly, so I put my battery back in and with a full charge AND plugged in, it still shut off.

I checked my RAM and laptop with the windows memory diagnostic tool but no errors came up.

Any other ideas I can do to try and find a solution, besides buy a new laptop?

I totally agree with Fireberd. Seems to be high temps.
As it's an old laptop, the heat sink must be clogged with dust.
Use open hardware monitor - Open Hardware Monitor - Core temp, fan speed and voltages in a free software gadget
Download , extract to a folder (C:\Program Files (x86)\HardwareMonitor) , run the exe file.
Under options tab set it run on start up.
If the CPU or GPU temp goes higher than 80ºC you will have to open and clean the heat sink.

May be heat. Laptops do not have the CPU cooling that a desktop has and are prone to overheating. Most have thermal protection and will shut off if it gets too hot. One thing to consider.

I downloaded the program and will monitor the temp after it randomly shuts off again and boots up.
But right now its going around 47-52

In full agreement, temperatures, do not place the notebook in areas where the .cooler can attract suet particles; Such as room games, blankets, etc. Another thing and for the care of the same is not having or using the laptop on the legs other than being dangerous attracts amount of dust particles. Having an external fan you have to look for the compatible model where you have the fan on the exact side of your laptop.
Fix the connectors if they are s-ata that are attached to the connector, in your case also the hard disk that is not saturated by the functions that are performing the temperatures can be high and this, for security stop working (rare because according to says That no recovery messages appear). For me.

Taka, with CPU load at 10% you already have temperatures of 49ºC. I would say that you must clean the heat sink.
On the service manual http://h10032.www1.hp.com/ctg/Manual/c02638165.pdf at page 4-51 you will have the instructions to get it done.

Your fan should be very noisy as well,
check your power settings here, see screenshot.

If you feel that you are up to the task, you could use some high-quality thermal paste to affix your heat sink to your CPU.

Arctic Silver 5 is an excellent thermal paste:

Doing this can bring down the temperature significantly.

If you decide to do this, then you should do a couple of other things while your computer is disassembled:
* Replace the CMOS battery -- your computer is old, and so the CMOS battery should be replaced.
* Get ALL of the dust out.

Make sure you wear an anti-static wrist band while working on your computer. Here is an example:

Thermal probem. Get somebody to re-apply thermal paste and make sure the fan is running properly. Also clean the vent to make sure there is nothing blocking the heat exhaust. If you look in the system event log, you will see the error message.
