Decent laptop for djing?

I was wondering what are some cheap options for laptops that are decent for djing, mine is getting pretty outdated and while it does fine with most VirtualDJ features it lowkey tries to blow itself up when it comes to stems. I'm in a very third world country so please try not to suggest anything too crazy! It took me months to even save up for a flx-4. Suggestions on at least what specs I should look for are welcomed. I'd prefer windows as I would probably use it for uni stuff too, but if you insist on mac I might give it a shot. I'm just looking for something that won't die on me mid set.
