Please post your system information, without this we can't really help you, we can only guess.

You can go to this website: http://www.systemrequirementslab.com/referrer/srtest
Select "Second Life" from the menu, click the button, then you can copy and paste the results from there.

Or, you can go to Start > Run > then type "dxdiag.exe" in the box and click OK. Then save the results into a text file, from which you can copy and paste the information.

When was the last time you updated your video driver?

Sometimes the latest drivers are not always the best option.
I updated my old PC's card sometime ago and had a terrible time ..rolled back and the probs were gone. You mentioned not having trouble before so it might be worth trying with the drivers you were using then.

Could be a lot of other reasons too ofcourse either way good luck with it all.
