What should I do to fix my totally unresponsive Windows 7 (very slow folder opening changing names on folders, very slow internet, everything very slow)?

I have already run virus-scans with both Microsoft Security Essentials and Malwarebytes PRO and they did not find anything.

Then I checked my system, and the battery and the fan did not pass the tests.

Battery can't have anything to do with this, but what about the fan, is it possible these Windows problems are due to the fan causing everything being overheated and thereby unresponsiveness and sluggishness and even freezing windows and a black window for a long time when I opened Google Chrome?

I have Windows 7 Home 64-bit.

Certainly, the Cooling fan can be the cause of your issue.
Try blowing or get it fixed from a vendor, either the reason you are deemed to change it.

Probably RAM is overheating is the other part to look into!

It it still slow when the laptop has cooled down? Overheating of the processor shouldn't
cause problems until it heats up after a few minutes.

I would concentrate on item #2 in this list (Reduce the number of startup items)
Then work on eliminating unnecessary services as described in #1

Another Guide ....

First install a thermal monitor program (there are lots of them), and have it check to see if the CPU is going into thermal throttling.  If it throttles on an otherwise idle system then there is a hardware problem that must be addressed first.  It's not at all uncommon for the cooling air ports on a laptop to be blocked by lint and hair that is not visible from the outside.  And if the fan isn't spinning, that explains all the other slowdown problems right there.

Get a copy of Microsoft Autoruns and have a look at what is running at startup time.  Chances are you will find quite a lot of stuff that does not need to run at all.

If this doesn't improve the situation significantly, look in your Startup group for more junk such as the Office toolbar and Office updater.

Good day,
                   By chance can you give me the specs of your system? You can use this tool to verify the temperatures on your laptop, Speedfan. http://www.almico.com/sfdownload.php. Normally your system would just shut down completely when overheating badly. You can check to see if your hard drive is failing or have bad sectors use the free version of Hdtune to check. http://www.hdtune.com/download.html Hard drives with bad sectors can cause those kinds of problems.

Hi hemesalpha,

This article I wrote a while back may be of some help.


I hope that's helpful.

you wrote :  "Battery can't have anything to do with this, but what about the fan, "  here some answers for you:
Battery not possible you say? WRONG - since it is part of your system, AND has an 'intelligent" interface - it can influence the whole system
but of course, the fan is most ly responsible, so: install speedfan, and monitor temps
if it does not boot, open the system, and clean the fan - i suggest not to blow out the fan from the outside, since you blow the dust IN the laptop

here my laptop troubleshooting guide, i hope it helps you :
- remove all external devices
-you can disable devices from BIOS to test (sound, lan, etc..)
- if no display - test with an external monitor
- test if it runs from battery alone, or from AC alone
- test also with a known good battery !
***some laptops have a reset button - if you have one use it!
- remove battery and AC adaptor, hold power button for 20 sec, connect AC and reboot --> any display ? if NO -->
- disconnect all disk and cd drives, battery , and other cards and peripherals, leave only 1 ram stick
- boot -->any display ?
-if you can access the bios battery, remove the battery, AC, and bios battery for a minute to reset the bios
or test it, it should read 3 V
*** you can test the disk on another pc, if you like !

===>>you can test if the mobo works outside the casing, connected to power and external video  !

you can also remove and reseat the video plug - it sometimes comes loose

Thanks everyone, a lot of good tips I received here. I received a lot of jobs, couldn't reply until now. I've begun to power it down during the nights (had it powered on 24/7 earlier), works better now, can use it. Will continue for a few days and always turn it off before going to sleep. Will soon buy a new computer (this one is from 2012 or 2011), just hope this one will survive a few months more.
