Keyboard Malfunction

[atrociousPanda]

For two months my Standard PS/2 Keyboard has been malfunctioning, specifically the Q, S and D keys.
My options for this problem are extremely limited in terms of practical solutions, for I run a Toshiba Satellite L655. Specs are in my signature below.

I can't use an external USB keyboard either because both my USB 2.0 ports are broken (which I plan to replace later on)

Is there any to fix this? All drivers are up to date.
