my pc was fine until I have decided to add a 4gb ram 1600mhz. when I installed the ram it wasn't supporting it and keeps restarting my pc. tried cmos reset and other recommended thing found here but no luck. so I updated the bios with eblu software. still same problem.. then I found a bios for windows 8 of my model and flashed it with cpu evo ii. after updating both ram worked but pc gets freeze at login page. keyboard, mouse nothing working.
what to do now? I tried uefi, lagacy thing on bios. still no luck.. help me please
