My Toshiba laptop emits a high-pitched whining sound that starts and stopps irregularly. I thought it was the hard drive, but I just replaced the hard drive and the sound is unchanged. My friend recognized the sound as that of a failing graphics card (I know this is an integrated processor, though), and we localized the noise to near where my processor is.

My questions:

-do you agree with this diagnosis?

-can anything be done?

-is there a way to "underclock" this - to prevent/delay failure? I am taking the medical school Step 1 board exams in 2 months, so I want to preserve my computer until then. (I am making frequent backups.) I will not run any videogames on it, though I do use Macromedia Fireworks to edit images on a semi-regular basis.

Thanks for the help!

 

Stats:

-the computer has been running slowly recently, but that might be my immagination. It can still run all my aplications, etc. without problems.

-The "CPU Usage" (in the windows task manager performance tab) idles around 29% on a fresh reboot, no applications launched. It is also idling around that number right now as I type this message, though with more variation (26..34%)

 

More stats:

Issue Details
above

Motherboard or System Make & Model
I'm not sure. It's the default motherboard for:
toshiba satellite L775D-S7222


Display Device(s) and Connection(s) Used
Generic PnP monitor, default with laptop

Applications and Games

no specific applications or games. I use MS Word and PPT 2003 most often, as well as Chrome.

System Memory Type & Amount
6 GB RAM

Additional Hardware
old hard drive was the default: hitachi hdd 5k750-500
New HD: Western Digital Scorpio Black wd5000bpkt 500GB 7200 RPM
The old hard drive was cloned onto the new one - not a fresh install. (The switch to AF was handled properly using WD Acronis True Image. I don't think it's a hard drive issue anymore.)

Additional Details
Avast antivirus
semi-recent scan with malwarebytes Antimalware, found no issues.
I always use the laptop on a flat surface, never my lap.

When was the last tome you cleaned out the heatsink fins of dust, it doesn't take much to clog it up and overstress the fan.

I blew into the airvent using compressed air, if that's what you mean. The vents haven't ever gotten very clogged, though. I haven't ever opened up the computer to look at the motherboard (or the heat sinc directly), though.

You have a dieing bearing inside the laptop that cools your APU then if you've blown it out. RMA your laptop and have toshiba fix it if its under warranty.

What is a safe core temperature? I've been running it all day today with moderate use (loading large files, but no gaming), and the temperature has ranged from 37 to 66 degrees C.

According to http://products.amd.com/en-us/NotebookAPUDetail.aspx?id=8&f1=AMD+Quad-Core+A6-Series+APU+for+Notebooks&f2=&f3=&f4=4&f5=FS1+uPGA&f6=&

AMD is saying 100C. Which I wouldn't believe if my life depended on it seeing as how Desktop Vishera CPU's are rated at 62ish max C. 

Second the reason I don't believe that is because the A10's are rated at only 74C.

Third reason I don't believe it is because the AMD Radeon GPU's Thermal downclock happens at 100C. 

So I would *never* consider anything past 62C on *any* current piledriver/bulldozer CPU/APU's. Safe for product longjevity. But I mean hey if it'll work at 100C great, I just won't imagine it'll last very long.   (according to AMD) I Just know one thing. You have to have pretty !@#$ty cooling to have a 35W TDP item running that hot.
