Hi guys. I have a lenovo y50-70. My screen started flickering the minute i updated to windows 10, indicating a software issue. I tried upgrading and downgrading my vga drivers with no effect whatsoever. I clean installed windows 10 again and still the same issue. I updated the bios as well.
I tried the video that says to disconnect and connect the screen cable. It improved the issue for a short while and then its back within 2 weeks.  This is strange as it suggests a hardware thing despite the fact that the issue only started after updating to windows 10.
I also tried disabling the two problem reporting services as some one suggested and no effect.
I spent hours  (if not days in total) researching this and i tried many things.  I have headaches because of this flickering and i can not work. 
Please help.  
PS. The issue never happens inside games and is more recurrent while browsing.( again indicating software not hardware)

Regards

Although it's usually a simple choice between software and hardware, as technology becomes more complicated we are finding that problems aren't as simple as that anymore.

In particular, compatibility and low-level driver issues can act as both.

 

Have you visited the Lenovo y50-70 support page and updated ALL of the latest, W10 compatible drivers?

 

IMO, the easiest test at this point would be to clean install the previous OS in order to see if the problem remains.

If it does, then you'd have to presume that it's a hardware problem.

If the problem doesn't come back - then the system is OK, but you may have a compatibility issue/low-level driver problem.

Then the next step is to update ALL of your drivers to the latest, W10 compatible version available on the lLenovo y50-70 support page.

Yes I did. I visited the Lenovo y50-70 support page and updated ALL of the latest, W10 compatible drivers that are verified by lenovo.
It is impractical for me to re-install the win8 now (it was preinstalled and my activation key was changed to be of win10 , I dont think it supports win 8 anymore). Moreover I cant do the whole lose data and reinstal programs again.
Any suggestions?

You will be able to revert to W8 - just how to do it depends on your OEM and it's support (recovery media, etc).

If you choose not to revert, then I have these suggestions:

1)  Uninstall your antivirus, then use the removal tool for it (there's a list of most of them here:  http://www.carrona.org/avuninst.html ), then install a freshly downloaded, W10 compatible version.  Some A/V have difficulties with the upgrade, so removing them and then reinstalling them will help how they run.

2)  Download fresh copies of the latest, W10 compatible audio and video drivers for your system.  Then uninstall the current versions from your system.  Then install the freshly downloaded versions.

3)  Get ALL available Windows Updates

4)  Get ALL available, W10 compatible drivers/programs from the manufacturer's website.  If some aren't compatible w/W10, check here about uninstalling them.

5)  Get ALL available, W10 compatible drivers/programs for any add-on hardware and any software that you installed previously.  If they aren't compatible, please uninstall them.

If this doesn't fix things, then post back so we can discuss the following options:
- continuing to attempt to fix this copy of the OS
- Reset of the OS (considering both the "Keep My Files" and the "Remove Everything" options)
- revert to the previous OS (both at less than 30 days, and at more than 30 days since initial update)
- revert to the previous OS with another attempt at installing W10 (I don't recommend this)
- clean install of the previous OS
- clean install of the previous OS, then update to W10 (only needed if a clean install of W10 fails)
- W10 clean install
