Laptop keeps getting BSOD randomnly.

[Irtaza23]

So as the title says, it just happens randomly about like 5-6 times a week. I have no idea why, I've used a virus scanner and I can't find anything. This usually happens when I change my battery from the weaker to stronger one or if I plug in my charger. But I surely can't tell if that is what causes it because sometimes it happens without me doing the two things I mentioned above.

Alright so I followed the instructions you gave me and the first two tests went fine, but when i used the next three cleaners there was so much of malware and unwanted stuff which I thought I had removed but somehow remained in my computer. If the BSOD doesn't happen again I will let you know. Thanks for the help. However I wanted to ask you why you preferred those 3 softwares? Why not something like CCleaner, avast etc. Are the ones you mentioned much better or is there another reason? Also, should I continue using these?

 

[ICIT2LOL]

No Irtaza mate they are the usual ones I and many of the other members use and recommend (I do) as a matter of a first try / scan before one gets into the heavier stuff - as they are free and I personally use the paid for MBAM on two machine and free on the other three.
They are quick and as you will know no AV is infallible even the Kaspersky I use on all my machines.

The CCleaner also a top program to run is not a malware scanner more a rubbish files cleaner amongst other uses. I use it on a very regular basis say before every time I shut down. The registry tidy feature I use also but always make sure the registry stuff it finds is backed up to Documents just in case the machine goes down it is then only a matter of merging them back in again.

Now if you want a bit more go out of the machine have a look at this

but if you do use some of the choices in this tutorial that use registry changes then I would if I were you back up the registry before doing anything again it can be merged back if things go south - highly unlikely in fact unless you do something really silly - impossible because the authour is a most brilliant fellow.
I always advise anyone to back up the registry before doing stuff in there and also as a must do on clean installs.

Edit: Followed this guide to fix the usb problem (http://www.sevenforums.com/tutorials/165554-usb-driver-general-fix-problems.html)
Updated BIOS. If the problem persists I will post it further

The BSOD showed up again. I forgot to mention three important things about the error.
1) One of my usb ports its broken however it still has the metal contacts which makes it work. but I don't use it ofcourse.
2) The BSOD screen shows BUGCODE_USB_DRIVER
3) The BSOD happened while my laptop was off charging, it happened seconds after I changed my power plan from eco to balanced.

Ok now the broken USB I am not sure if it would cause the BSOD as it depends on how "broken" it is ie a physical broken or a driver broke.
If you are sure of doing ti yourself you can go take a look and see - see this

if you do please make sure you understand the info in this first as the ribbon cables you need to disconnect and reconnect are very fiddly and easily broken if forced out.

TAKINGLAPTOPS APART

I always spread out a large whitebath towel on the work top and using cloth or ordinary duct tape keep to be stretchedout fixed down to the work top. This isbecause when removing the sometimes very small screws it stops the screw form beingdropped onto a hard surface where it almost always will bounce and even land onthe floor never t be seen again. Of course if that happens you can scour thefloor with a strong magnet in the case of steel screws the brass ones (thereare some that have brass screws in certain spots) unless brightly coloured youwill not find especially in carpeted floors.

I prefer to use a battery drivenslow speed screwdriver as in pic and leave the screwdriver bits stuckonto a strong magnet or stroke then longitudinally to magnetise them it makeretaining the steel screws so mucheasier especially when replacing them. (If you drop on into the machine youwill need to completely disassemble it again to remove it)

It is also advisable to keep thescrews in separate containers as they will be of different sizes and locations.
In the pic I show where the USB ports are connected to the motherboard and they are usually just some small soldered joints / fixings and easily replaced.

I don't think I will be taking it apart, it's just too risky. But I used the other methods I mentioned above. Let's see if they prevent the BSOD. Thanks for helping me out so much, I really appreicate it!

Well it is as you say risky if you are not used to doing it and I only got it right as I could after many attempts and practice. Haven't actually "lost" one but have spent many hours doing repeat "take downs" to rectify things I have forgotten.
Having said that though I have saved many dollars as the techies see you coming.

We just carry on eh?
