I always get stuck on vaio logo when i start my computer after a long time.
I have to press the f2 key and then bios password screen comes and i press esc since i don't know the password. Then boot menu pops up then i select internal hard disk then my computer works. Everytime i have repeat the same thing to make the computer work. Is it a software problem or hardware problem? I tried vaio hardware diagnostics but it showed everything ok. Pls can u help me people?

This is due to password settings enabled in BIOS. But you can change that by entering the BIOS. If you can then go in security and clear the password. The message will not appear back. But if the password does not allows you to enter BIOS then you might need to remove the CMOS battery from the motherboard. That is a hectic job. Other solution is to flash your BIOS to remove the old settings. But it is very risky.
