Hi guys , i'm having a problem with my Gembird KB-UMGL-01 , i bought this keyboard a while ago , and it was all fine , and good , but now it's starting to have problems , especially with video games , it's really a struggle to play video games now , cause , when i hold TAB for excample , in counter-strike it should show me a scoreboard , but the scoreboard is just going crazy , it turns off and on , and i have tried to reinstal drivers
