My computer freezes. Should I take it to the store I got it from to see if they can check it out. Or should I get RegCure? It is still on warranty. I got it last year in July.

Please check your cookies and temp files. You will want to also find your receipt it's possible if you take it in to the place that you got it they will be able to replace it or fix it for you for less than some other place. Best of luck

Not enough info

If possible please supply as much information as to describes your problem or question if it applies to request. Most are easy and if not supplied, they may be asked eventually depending on situation.

What operating system you're running, and its version?

Any hardware add-on devices that you think might be related to the problem you're seeing.

Any changes that either happened or that you perhaps made to your computer around the time that the problem started; particularly any software or hardware that you installed or setup.

You can try a system restore back to when it was not freezing on you

Just go down till you see "Use System Restore" and follow instructions from there

Don't worry about messing with it if its still under warranty! Let them replace or fix it. But like seahawk said there is not enough info for us to tell if it could be a general problem or if it's a problem that resulted in something you may have did or didn't do!
