Windows 7: CPU overheating after switching to x64

CPU overheating after switching to x64

hi all
i was using windows ultimate x32 and i didn't have any trouble with it except ''2.8ram usable'' (i have 4gb RAM)
so i've switched to x64 to solve this problem. there was only 3.68gb usable.
i noticed that the CPU is overheating (67 C) and when scanning with malwarebyte it gets to (83 C)
and when using IDM or VLC it gets over 90% CPU usage and there is no background processes
and it shutdown when it gets too hot. i have never faced this problem with x32
i've updated the latest drivers and latest windows updates
and there is another thing when i scan with malwarebyte and listen to music i got a freezing sound and the cpu is 100% so i closed malwarebyte and tried to listen to music with visualization on VLC i got the same crashing sound .
thx in advance

my compture specs:
acer 5733z
intel pentium CPU p6100 @2.00GHZ 2.00GHZ
4gb RAM ( 3.68gb usable)
Intel HD graphics
Toshiba hdd 500gb
windows x64 ultimate '' updated windows and all drivers(bios,chipset,graphic card..etc)"
*no virus or malware or anything it's clean
*sorry for my bad English and sorry for posting the thread here i don't know where to post it
please help i'm thinking of returning to x32 but the problem is there is only 2.8gb usable of RAM

Did you upgrade hardware between the OS version switch?
Was the heatsink ever removed?

Are you performing any difference actions that you would not be performing before?
Do you have a max reference temperature at 100% CPU usage back when you were on x32?

How did you perform the x32 to x64 change?

As Erick has said mate has the heatsink ever been removed and / or the thermal compound renewed?
Those temps are fairly out of whack for a 35 watt TDP CPU and if it were mine I would be do the thermal compound as soon as.

When you do that you need to make sure you do it properly and use the right cleaning solutions and one I always use is Arctic Silver Incorporated - ArctiClean followed by applying the Arctic Sliver 5 Arctic Silver Incorporated - Céramique 2 I have found it the best with those type Pentiums.

i've never changed the heatsink
and i didn't upgrade any of hardware!
and i don't have a max refrence at 100% cpu usage but i never faced this problem ''auto turn off when it is too hot'' and cpu usage over 90 when idle or just istening to music with vlc visualization or downloading some files with IDM
the notebook is 1year old and the fan is clean
and i've preform the change with a USB boot with a clean iso

i've been facing those problems since i installed x64 just for using more RAM

Yeah no, that doesn't make sense. if that was true we'd have a lot of information showing it's better to overclock in a 32bit system.

I'd say check the services, which are using most CPU power, check if your ram is okay. Try a clean install.

It is not due to the 64 bit OS, at least not directly, so you should focus your investigation elsewhere, in particular on your hardware cooling.

My only guess is that there's something wrong with your installation or a program you installed.

It is possible that your CPU is damaged somewhere that is only used by 64-bit OSs, but that's highly unlikely. So unlikely that no matter how much you zoomed into the probability curve it would still be parallel with the number line.

Or maybe during the install something failed, but that's also unlikely.

I'd recommend, if you can spare the downtime, doing a clean reinstall of 64bit. For the first while don't install anything except from Windows update (and drivers that Windows Update can't find) and see how it runs.

If that still doesn't work, then I'll be mystified if it works after reinstalling 32-bit.

Well I am guessing you have a stock cooler and I can only suggest that you upgrade to an aftermarket air cooler and get that thermal compound changed.

As for the CPU usage well something is suing it what have you got running in the Start up tab in msconfig? To see that look at Option 3 in Startup Programs - Change

I think you're all approaching this the wrong way.

  • What software or process are you undertaking in order to determine these temperatures?
  • What percentage of your processor was video watching (VLC?) using prior to the installation of the 64-bit OS?

  • You have 4GB of memory, correct? Are you nearing exceeding 3GB of memory usage at any given time?

I think your chip would explode if it were actually running at these temperatures, and if it is then I would suggest not using it until you have found the solution.
However, I am inclined to believe that these temperatures are inaccurate.

  • You have recently updated you BIOS. If it's possible, flash it backwards—SAFELY. Generally when it comes to BIOS, the consensus is if it isn't broken then don't fix it. This is much more likely to cause what you are experiencing than the operating system being 64-bit.
  • Check Device Manager for any (!) points or missing drivers. Make sure everything is installed properly.
Failing all of this, you'll need to get it serviced because it's too dusty and the application of thermal compound has worn.
