my video card burnt

I'm amazed at you peeps. Have none of you ever owned cats? It's right there in the first post, all the clues you need, "cat shop". If this is anything like a pet shop the OP would have massive amounts of hair clogging up his entire system.

Unless your system is in an office which is closed off from the rest of your shop any system part which has a fan is doomed to overheat unless you clean it out I'd guess at least once a month.

Hopefully you have a card which has lifetime coverage.

I'd recommend you look for replacement parts which are fanless, and look for a case which includes washable filters. (I believe one of the P180 types and the Antec 900 v2 has them. Not sure on others.)
