I just bought 1 gig of ram, and stupidly put in my old ram and new ram in backwards...at least I think I did for both for both of them. I started the computer, and I heard a snap and smelled some smoke so I immediately turned it off. I learned I put it in backwards, and now I'm wondering what the damage is. When I put in my old (512 DDR) ram the computer makes beeps as if it wasn't in there...for both slots. When I put my 1 gig in the computer doesn't make any noises for both slots. Regardless, I get no image from my desktop, and my joystick,mouse,keyboard etc. Are not working. I tested my video card (7800 GS OC) because the fan was working and no display was showing, I took it out and put in my old one (9600 XT) After turning the comp on, the fan worked for about 20 seconds then stopped. I'm wondering what else could be damaged? Could it be the ram, mobo? Could there be other things damaged like my video card? My video card slot? please help and give any advice you can. Thanks.
