Windows 7 overheating my pc?

Hello,

5 months ago I bought a Toshiba Satellite z830, recently over the last 2 weeks I've noticed it getting very hot while running programs etc (i figured this was normal), however it gets so physically hot I thought maybe not so normal. I download speccy and it showed the following:
CPU: 80 - 85 degrees
Motherboard:80 -85 degrees
Harddrive: 55 - 60 degrees

Last night I would get those temps about a minute after I turn on the pc, after about 5 minutes windows will freeze and I would have to shut down. Some times a window would pop up saying 'the program is not responding' or something like that.

I figured this is a hardware issue and have booked it in for a service with Toshiba's mobilecare.

BUT... Way back when, I though I'd try ubuntu, I didn't really like it and kept using windows. When I started getting issues last night, I thought I'd try booting into Ubuntu to see how that goes, and after
using it last night and today I have no heating issues at all and the pc runs perfectly. Which makes me believe that this is a windows issue.

If I log back into windows and do nothing it will freeze in 5 minutes everytime, so I can't really give you any diagnostic info because windows will sh*t itself. I tried sfc /scannow it got to 72% then froze.

Thanks for reading my essay and please help!

It is well known that Toshiba notebooks poorly resolved cooling components.
I'm bought the docking station, although the difference is not large, but anyway better that before.

I tried crystal diskinfo and it said everything was good. I guess I'll just wait and see what the Toshiba people have to say.

Have you checked for dust build up? Vents should be cleaned periodically with compressed air. Is the fan actually spinning? Sometimes dust on the blades or spindle will slow down rotational speed. Also, when using the laptop never place it on your lap or any other soft surface like a pillow, bedspread, etc. A lot of people also recommend using a cooling pad to enhance air circulation.

after a while you get a build up not just on the fan but the heatsink the fan is suppose to blow air out through.

so could be fan clogged
air vent clogged
hdd faulty..lets be clear those temps are bad for a hard disk.

but you are taking the right course of action by sending it to a repair centre.

I`d kill for numbers like that in farenheit but i`m sure they`re celcius. No wonder, that`s 176 degrees farenheit.

Reinstall windows.
