Q: Somehow the support to my expansion slots dissapeared.....and this is a major problem because if the cards slide out while the pc is on itll burn...so now im terrified to use it Any way to find a new one? or buy one online
A: Well, yes that's a major concern. However, assuming that you find a good location for your PC up against something sturdy like the wall, then there should be little chance it will get bumped. You can use electrical tape to secure the card to the side of the case or whatever is nearby that works best. In the meantime, look for a replacement case. If this is a branded PC such as Dell or HP, then contact the manufacturer to get replacement parts.
