Welcome to SOLIDWORKS forums Sandeep.
SOLIDWORKS on cloud is expected in recent time but I can't comment about the time frame exactly. No I don't think someone is offering that kind of service. On the other hand if you're computer is old then even you won't be able to play nicely using remote access.
So better get the pc updated or probably buy a new one. Check this forum about the various configuration and pricing and check which one is best for your pocket. Also check (but not sure on this) if you're eligible for a student license.
