My computer just shut down yesterday. I believe it was a power surge, but I am unsure. Anyway…The power source was toast. I switched it out but the only one I had available was 250watt, the old one was 550. Would this cause my computer to run slower?

Is there any software available to run a diagnostic from home.

Thanks!
Remo, If your not even going to read the question, why bother with writing a response? Thanks for the dumb reply.
