Hello I have really problem with repeatedly BSOD on Lenovo A58 machine, MT 7611-77G. I replaced Mobo and ram, all parts original from lenovo. Machine is in warranty. Problem still occurs. BSOD appears only when machine boots to system. I am 100% sure that is driver. I need help with searching because i have not much time to fix this problem. Please people help me with debugger or explain me dump file. I am going to upload it just now. I tried latest drivers for graphic card (integrated), sound card (integrated), chipset. I also up to date bios. Pc working fine in system but sometimes, really sometimes BSOD occurs when booting. I tried disable sound card also, but still not helped. Sorry for my english, still learning.
