gan ane punya problem nih sama nvidia geforce gt620m ane. ane pake laptop acer aspire v5-471g

langsung aja ya:

pertama, pas ane buka nvidia control panel ane muncul tulisan (warning gitu) "an nvidia graphics card was not detected in your system"

terus langsung aja ane uninstall nvidianya. nah pas ane install lagi, muncul tulisan "This graphics driver could not find compatible graphics hardware". padahal ane udah download sesuai sama drivernya.

terus ane udah coba juga install ulang intel hd graphics 4000 ane, dan hasilnya tetep aja muncul terus tulisan "This graphics driver could not find compatible graphics hardware".

ane udah coba liat dari device manager, eh ternyata nvidia ane ga ke detect.

mohon bantuannya para master
