There will not be an Unlocked Bios for your Packard Bell En TS11SB. It is very time consuming and takes skill to unlock a bios, so modders like SVET and Prema only works on enthusiast systems Like Clevo, MSI, and sometimes Alienware.

That being said, I do not think your problem lies in the bios, and "unlocking it" will do nothing for you but show you some advanced security features.

I would suggest reverting back to windows 7. There is no benefit on being on 8.1 in such an old low budget laptop. Your issues are most likely driver related.

Without any ample info, You most likely have 1 (or more) of these 3 problems

1) I would roll back your Radeon HD 6600M drivers back to the last time they were a supported card by AMD (probably 2015) as the card is from 2011

2) Could be thermal issues. Should note Windows 8.1 runs hotter than Win 7. When is the last time you cleaned dust out of fams and radiator fins? Most likekely need new thermal paste too.

EASY TEST:
Run HWinfo64 "sensors only" while gaming or benchmarking to see if you are overheating

3) Could be just a dying GPU

 

Thank you for responding.I clean dust 2/3 times in week and half i dissagre with you in one part my laptop does not overheat since i opened a cover for ram wifi and hard drive and put laptop on cooler master.In windows 8.1 and windows 10 not overheating can gamming but when i update drivers its boot slow as f... My thermal paste is Halnziye with this mark HY 510.when i buyed my laptop ewerything worked fine no slow boot etc but as soon i installed windows 8.1 clean install no upgrade i updated bios(did not reset cmos batery at the time it is same as the cmos on desktop mobo and when i try to boot Linux with boot chip in bios set from integrated to switchable Linux tries to read from dvd or usb flash but it show something like drm atom bios something like that it strugle a litle bit to boot and its booted but with single chip onboard boot just fine)I can run windows 10 without trouble still use it no overheating no nothing but as soon i try gaming with booth chips after 10 min gameplay sometimes its not hot sometimes it is but barely noticable and it shuts off without windows is shutting down or errors just shuts off like power is cut.
