We have been warned from the start of the year that this was coming by EA/Maxis. It was originally coming after 29th February.
I once had to resort to a credit card to buy a laptop that could run Sims3/4 and was lucky enough to find my bank was offering 0% for 17 months to transfer CCs or Shop cards. I did and paid off my laptop on 0% monthly for those months and hid my bank's card so that I couldn't use it for anything else since. You have to do a bit of researching to find a good deal for a new one and it is a good time of the year to do it.
Otherwise some Sims Website like MTS might start some threads to help 32bit'ers. They made good machines in those days but they do suddenly give up the ghost with the CMOS batteries failing. One did on me last week.
