Laptop Running very Hot

Did some research on this and haven't seen anything that seems to be my problem.

Running SpeedFan, attached the image.

So here's my problem, HP G62, it's about 2 years old, pretty heavy usage.
I've cleared out startup programs and processes extensively, running my computer on absolutely minimal processes and services, on average my CPU usage never goes over 10%, yet even with this stated it often times runs extremely hot while just casually browsing the internet.

I know somethings wrong because my wife has an identical laptop and she can be doing virtually the same things as me (browsing the net, watching videos, etc.) and her computer will be fine.

This problem is exacerbated when I'm running videos (obviously) or games (duh) but it's to the point where I can't watch more than an hours worth of video without it overheating and shutting itself down to protect the system.

One major difference between my wifes computer and my mine is that I dual boot between Win7 and Ubuntu, as well as having a couple other OS' (Win7 Enterprise, Server 2008, etc.) on my computer so I can run them virtually for learning purposes. I have removed most of them and put them on an external HD but even after clearing my computer of almost 80gigs of memory it is still running very hot.

I do not use it on bed/pillow/blanket or any of that very often. You can rule these out, as it overheats often even while sitting on the table. This past week alone it has overheated at least 3 times and shut itself down because of it.

Any ideas?

hi JJblayde!

First you need to shut down your laptop or risk serious damage to your CPU. the reason being is that the results of your speedFan that you so kindly posted is that your fan(s) are NOT running at all(0 RPMs isnt good), so until we can figure out what is causing your fans to stop and fix it you need to keep it off and only use your laptop for short periods that wont hurt it( i believe <2 mins at a time with a 5-10 min break to let the heatsink cool wont hurt it. please someone correct me here if i am wrong.)

now jjblayde depending on how you feel will depend on what happens next. since your laptop is only 2 years old you it *MIGHT* still be under warranty, and in that case i highly suggest you send it to HP and have them fix it, because otherwise you might risk voiding your current warranty. IF you can take this option do your best to backup the rest of your data from your laptop!

if your laptop isnt under warranty then you can either take it to a trained professional, or take the laptop apart yourself, because to find out whats causing the fan to fail requires being able to get at it.

if you chose to try to do it yourself then please read This Guide to disassemble your laptop. if you chose to do this please read through it first and remember that you dont have to take the LCD apart and you can stop at step 25 to access the fan.

since this isnt a software issue can i please have a moderator move this topic to the proper hardware fourm.

Interesting. Sorry for posting in wrong thread, wasn't sure if it was Windows 7 putting too much stress on my computer, or if it was a problem with some drivers causing my computer to run more than it should, etc.

It sure does sound like the fan is running most of the time. When it starts getting really hot the computer starts spewing hot air and I hear the rotation. Though the speedfan readings are ominous..

I've taken apart this laptop before so I'm pretty capable of doing it again. Not horribly concerned. Just not excited about having to do it either though but if that's what it takes.

The readings that you will get from Speedfan are determined by what sensors your MB has and notebooks do not have anything like the sensors on their MBs that desktops do.

Inspect the cooling fan and clean out any heat trapping dust at the same time, this includes removing the memory stick/s, blowing out the slots and then replacing the Ram securely, those notebooks are known to run hot so I suggest that you invest in a notebook cooler like the example @ http://www.newegg.co...Order=BESTMATCH

FWIW, if the CPU cooling fan is known to be none operational then under no circumstances should you apply power, it takes seconds for a processor to fry.

Yea see my computer was on for a very long time yesterday and ti ran just fine. So it appears as if the fan must be working, I can't be consistently using my computer for 6 hours straight without it overheating if the fan was non-operational.

So it seems I still don't have an answer. Remember that my wifes laptop is identical and it never runs as hot as mine. The only difference I could find was that I had drastically larger amounts of memory used up (she had somewhere around 20gigs on her laptop, where I had 120) I have since backed up and erased nearly everything yet I'm still experiencing this problem.
