Since a couple of days my laptop-Lenovo G575 gets once in a while a flickering blur screen like somebody wiped it with a sponge . The only solution I have now is to force shut down as anything else will not change that flickering blur status. Since that problem I've got also a few mouse freezes and a few blue screen of death(haven't got the message on the blue screen yet).
After this, please restart the system and check if the issue resolved. If it remains same then please contact the lenovo service centre and there the available representative will assist you.
Thanks and Regards,
