I have a HP Pavilion dv7, and recently it has been running much louder than usual. I don't know if it is just the fan, or what the deal is. Any ideas?

OK, usually when there is a noticeable sound difference in the loudness of the fan, overheating is an imminent matter. The reason for the fan noise increasing is due to the dust particles in the fan housing which is preventing sufficient cooling. Hence, the fan needs to have to turn at higher revolutions just to suffice in the cooling.

Now, the solution is to open up the unit and use compressed air to blow out all of the dust particles. This will enable to fan to cool the CPU at a lower radial speed, hence less revolutions per minute.

Please do not hesitate to let me know if you need any further assistance, i will gladly help.

Kind regards

HP Pavilion dv7-1285dx keeps overheating and shutting down

sure it does all PCs do that, full of lint, all do.
we clean it.
it has fan and vents
all fans all vents and heatsinks must breath or it overheats.
all do that not cleaned, drive your car around with the radiator blocked, boom.
all PCs run slow overheated, by DESIGN.
this slow down , reduces heat, and saves CPU/GPU burn up.
just like my chevy, truck, it cuts cylinders to save the engine.
same deal both.

same deal; same reasons.

Laptop hp pavillion dv7 turns off by itself when battery is in and it is plugged in Problem

Update the BIOS and check if doesnt work, try running a recovery on the sys.
If problem still persist than contact manufacturer as the sys has to be repaired
