[In screenshot: Thunderbird was just starting, hence the high power usage, otherwise NONE of those programs + a couple more would have the temps at 72°C, except momentarily. Before submitting this post, I closed Thunderbird and still have temps mostly around 71°C. Under this particular "App-status quo" would be in the 50s or even 40°C under "normal" circumstances.]
Hi there
I would like at the outset like to rule out a mechanical problem involving the fan & dust or something related to the heat sink, etc.
My Samsung laptop [NP355E7C-S09DE, Windows 10 Pro, 64 Bit, 8GB RAM, AMD A8-4500M APU with Radeon HD graphics, AMD Radeon HD 7640, etc] was upgraded from Win 8.1 to Win 10 in 2016 (or 2015?) and actually runs well. I ALWAYS try, just like now to have the latest Windows Updates installed + that of other software.
A while back 2 years or so after upgrade, about 1 - 1.5 years ago, I noticed if I tried to use some software like Driver Booster to upgrade the graphic card drivers or get the latest version directly from AMD, the CPU got really very hot even with the PC doing nothing, with temps at idle within 60°Cs and easily rushing to the 80s & 90°Cs if an application like Firefox or other stuff was turned on, the programs I mostly use.
The normal temperature for most of my activities is 50 - 60°C and then up to 70°C with some applications but hardly more or in rare cases & not for long.
When I reverted to the previous graphic drivers, things cooled down to normal, BUT there's a time I think may be related to a Windows update that made the high temperatures remain for quite a while.
I came to this and AMD forums at the time for help and most of the advice pointed to changing the heat sink or cleaning the fan, etc. I was sure the fan was not clogged. I bulked at the local prices for changing the heat sink and doing it myself because of causing collateral damage.
Somehow, possibly related to some subsequent Windows update, the problem went AWAY on its own, without changing anything. This has been the case up to a couple of days ago.
I had not upgraded the graphic driver and for the many programs I use when multitasking, including almost always having streaming video + multi-tabs of Firefox & or Chrome, the temps were mostly under 60 °C, withing the 50s.
The temperatures have of late moved considerably up, even when the PC is idling and easily go to 70 - 90 with Firefox & co open or with my usual streaming video, a situation which is not good and normal, with the fan blowing hard.
There's been no sudden clogging with dust this past week and I do not see which software I have installed in the last week that could be causing this. I ALWAYS have a limited number of programs running in the background or auto-starting & NOTHING I did not have 2, 5, weeks ago, same to services, using Wise Care 365 to limit the number of non-Windows services auto-starting, to a couple of known programs like the antivirus and just a couple more.
I have no reason to believe I have new malware as the Windows Defender with latest definitions + McAfee Internet security + Malware Hunter Pro all show no threats found in today's scans.
I have to tried to uninstall and install the graphic card drivers [downloaded directly from AMD] to the version I was using with no trouble for over a year (temps mostly in the 50°Cs when multitasking), but with this making no difference.
So my question is what could cause this sudden temperature rise and what solution apart from what I have tried ... (other than changing the heat sink + dust/fan, which i have no reason to believe are relevant at this point) and what solutions are there?
Before posting this, this is what the Task manager looks like in screenshot, though the values like Disk are currently, i.e. after making the screenshot mostly much lower oscillating between 0 & 47% in last couple of minutes - with Firefox + Photofiltre subsequently started. I normally can have many more programs running [multiple browsers tabs, video streaming] while multitasking without temperatures going to 70°C and mostly under 60.
I would appreciate helping understanding what is going on and above all how to stop it.
Regards
