Electrical with ungrounded and grounded outlets with computer and home theater?

Just moved into an apt in a house (tenant) - never thought to look at the outlets. They're all Type A 2 prong ungrounded outlets. Don't think the landlord on fixed income will hire an electrician. Need to run my computer and my home theater (different outlets). How can I do it when all cables are grounded and all surge protectors are grounded. Any answers?
