Hello and welcome to Tom's Hardware Forums.
We don't advise on password hacking here in case we help someone is trying to access another person's system. The same applies to CMOS resets because that's sometimes considered to be a way of bypassing a BIOS password, even though it doesn't often work.
If you take it to a professional and provide proof of ownership, they might be able to help. Toshiba's service agents will charge you £165.00 in the UK.
