Help, just switch case and now pc is unstable

[HKSturboKID]

I just pull my system out of my full tower case and put it into the new case I got from compgeeks and now the PC runs like shtz. Everytime I boot up, I got beeps every 3 seconds, I finally figure out that the memory wasn't seating right, fixed that. Now the thing boots up, but I get stupid characters all over the bios screen once the screen comes on and when I watch a movie or play game, the screen is so snowy and eventually crash on me with BSOD or it just freezes. I even removed all the peripherals from the motherboard and left just the cpu, memory and video card and still the same thing happen. I should have taking my mechanic advice, if it ain't broken, don't touch here! I am thinking that maybe my motherboard is shot! Anyone have any ideas?

I would check your vidcard first, if you have access to another try it out, also what card do you have? Gainward's 4200 had a lot of problems, which sometimes did not manifest for a while. possibly what happened is you messed up your vid card when you moved it.

I am using a mx video card and it work fine. I hope I didn't damage it during the move. I've an old PCI card, probably give that a try tonite. Thanks for the reply.

Try using the power supply from your old case. Cheap PSU's can be, well, cheap.

Yes, it indeed the Power Supply. I took out the one that came with the case and put in an Antec and it start up beautifully. Except that my pc is kinda mess up now since it rebooted so many times, a lot of system files got corrupted. Guess I have to repair the damn OS now.

Thanks everyone for your help.
