I installed D54250WYK graphic driver for Windows7 64bit. I try memory test which is standard function of Windows7 after installing graphic driver. The test show that memory has error. But Teh Test of Windows8 don't show error. I think that graphic driver for Windows7 is to destroy the Windows7 system. Is data destroyed during using Windows7? Please Tell me.
I use 'D54250WY-D34010WY driver bundle'(2014/07/01) and 'WY0027.BIO'(2014/07/10).
