Laptop Toshiba Satellite L745
Windows 7 64-bit
Intel Core i5 2410M (2.30GHz)
GT 525M Graphics card
A little more than 3 years old.
Started about 1 week ago. Basically nearly everything happens 10x slower. Slow to boot, slow to login, slow to load desktop, slow to manuever in Windows explorer. Even opening Google Chrome takes literally 5-10 minutes. Also every few minutes sometimes the computer hangs for 1-3 seconds. Interestingly when Google Chrome has opened,and web browsing is fairly normal except for the sudden 1-3s hangs. About 5 days ago it didn't even manage to get to the desktop. It took forever to log in, the windows toolbar never loaded, no icons either, I shut it down with the power button fearing it was a overheating problem. Didn't try to start the computer until today, opened the window to let cool air in and hopefully cool the laptop.
Task manager shows CPU Usage oscillates only between 1-10% despite the programs etc loading slow or trying to transfer files. It occasionally spikes up to 60-80% for like half a second. I downloaded CPUID to check if it was indeed a overheating problem at it shows the CPU at about a constant 55-65 Celcius, there are rare spikes to 80 Celcius. I am unsure how to interpret this. Note these temperatures I got by trying this with the cool night air blowing in. Room temp is probably like 10-15Celcius.
Also the computer seems to be 'not even trying'. I mean I hear the fan, but it only blows hard once in a while, maybe because the CPU is only being pushed once in a while. But it doesn't make sense because everything is so slow, why isn't the CPU working harder?
I ran CrystalDiskInfo on my brothers advice and it said my HDD Health Status was Caution. I want to post a log, but I'm not sure how to. I found the folder with a bunch of csv files, not allowed to attach them?
I scanned with AVG and Malwarebytes about two weeks ago, no problems detected. Didn't download anything since then. Actually the computer was slow but not as bad about 3 months ago, ran CHKDSK, found some problems and it seemed to fix the slowness then. It became a little slower again maybe a month ago, ran CHKDSK, no problem. Than last week this full blown problem appeared. I am in the process of copying essential files since as expected even file transfers are super slow.
So I would like to ask for help on solving this problem. Is it overheating, HDD failure, or something else? It would be great if I at least find out what the cause problem is to better determine my options. E.g. If it's just a cooling problem maybe I can save my HDD
Please do tell me what you need me to do to help in the diagnosis/solution. Your help is very much appreciated.
EDIT: Also I tried to open up my laptop to clean it and rule out dust bloackage, but I was unable to open 4 screws for some unknown reason. so abandoned it.
