My HP laptop is overheating, FAN is very noisy. It says Thermal shutdown occured......System temperature(90D).

I have remove all dusts from air vents and heatsink,update BIOS and apply new thermal grease on CPU but problem still persist. Windows shutdown automatically after a few minutes. Is there any expert who can solve this issue. Thank you.

You either used too much/little thermal paste, or the fan may need to be replaced.

Sometimes the heatsink gets clogged with dust, hair etc. This can be hard to see but you should check for this if you didn't do so already.

The video shows what I mean and also how to clean the fan thoroughly, which might stop it being so noisy :-

There are only about 500 flavors of the G42 so, if you want accurate information, I need the full model number or the product number (almost always ends in #ABA) from the HP sticker on the bottom of the laptop.
If; however, it is an AMD model, the odds are overwhelming that the GPU (Radeon something) is overheating; they're infamous for doing exactly that and are not part of the CPU chip.

Its a Japanese flavor of an HP G42-474TX and here is the US support page:
https://support.hp.com/us-en/produc...-series/4346229/model/5053107/troubleshooting
Unfortunately, the specs are unavailable and it shows two different possible graphics devices. One is the Intel HD which almost never has overheating problems; but, the other is an AMD and, in that vintage (2011), they had huge problems with overheating.
If it will stay running long enough, do Winkey+R or start -> Run and type DEVMGMT.MSC in the box then hit ENTER. The device manager should appear. Click the arrow next to Display Adapters and tell me what it thinks the video device is?
BTW (By the way), you may be able to seriously lower the temps by raising the back edge of the laptop with two rubber feet, a pair of erasers, or even a pair of pencils. Just a little more vertical space underneath can lower the temps a lot.

Please run DEVMGMT.MSC again, double-click on that "standard vga" device, go to the details tab, click the down arrow next to DEvice Description, choose the second one down (Hardware ID's), right click on the top entry and copy, then paste it into your reply, OK? (mine, for example, is PCI\VEN_8086&DEV_041E&SUBSYS_78501462&REV_06)

Its a royal PITA (pain in the a**); but, here is your maintenance manual:
http://h10032.www1.hp.com/ctg/Manual/c02623161
On page 92 is a picture of the fan/heatsink assembly; but, it is the part that is underneath #3 in the picture, not the CPU, which is probably overheating. It should have a gray or blue thermal pad that presses against the graphics chip.
Did you already take it apart once AND, if you did, did you replace that pad?

You're welcome!
But; as a note, WhatsApp only works on Windows 8 or above and I still use Windows 7 so I can't install it....
