Crispies · 01-26-2006, 01:30 PM

I swiched my cases and now my comp dont work. I am pretty sure i didnt do anything wrong. when i try to to on the comp my monitor just stays at a black screen and the light blinks i dont know what to do.

post your system specs
check all cards are seated and all cables are secure

Crispies · 01-26-2006, 02:59 PM

xp pro, pentium 4 2.0gh, 1g ram, geforce 6800 thats all i remember cant check the specs obviouslly. and everything is plugged in right

Crispies · 01-26-2006, 03:04 PM

i just tried to turn it on just now and now the comp comes on for a sec then turns off

Crispies · 01-26-2006, 03:06 PM

oh and i forgot to mention that i got a new 450 watt power supply with the case

dai · 01-26-2006, 03:12 PM

case supplies are usually generic and not much use
set it up out of the case with
cpu
video
ram
and see if it posts
it sounds like the m/b is shorting to the backing plate or the cpu heatsink is not seated ok

poisonfish · 01-26-2006, 03:12 PM

have you checked the screws holding to mother board to the new case <and have you used nilon washers >sometimes the screw heads make contact to board ..i would remove mother board and put it on somthing conductive cardboard is good and try to boot up

Crispies · 01-26-2006, 03:26 PM

what should i use to insulate it while its in the case?

dai · 01-26-2006, 03:29 PM

if shorting to the backing plate is the problem,it is caused by incorrect amount of standoffs or one in the wrong place not lining up with a fixing hole

Crispies · 01-26-2006, 03:36 PM

all i got with the case was some little screws to screw into the case then u put the board on them then screw the board to em but i could only use like 5 cuz my board didnt line up on any more

Crispies · 01-26-2006, 03:48 PM

im gunna hit the store so could u tell me what to get to insulate the board from the case

Crispies · 01-26-2006, 03:57 PM

i just noticed when i touch the case and something metal i get shocked

Crispies · 01-26-2006, 04:53 PM

i need to know what to use to insulate my mobo from the case. Whenever i touch the case and metal i get shocked so is there a way to fix that

Crispies · 01-26-2006, 05:51 PM

anyone know?

Hi,

Are you using the motherboard standoffs? Those are the little pegs that screw in your case. If you are, have you made certain (this can be a tough one if you aren't an experienced builder) If you have the posts and the correct number put in, then you can use a couple of methods.

First, you can put a piece of black electrical tape between each standoff and the motherboard. You can do that by putting the screw in the motherboard side, then putting the piece of tape over the screw with a little hole in the tape for the screw to fit in the motherboard post.

Second, if you go to a hardware store, you can get little insulating fibre or rubber washers that will fit on the motherboard posts and insulate them. Hope this is what you are asking. Just make sure there are not too many posts in there, because this is usually the reason for that problem. Oh, almost forgot, some times the motherboard touches the side of the case, so make sure that is not a problem. Hope that helps.

Hi,

I hope I covered it all, but just wanted to make sure that most of those problems are caused by having too many posts in. Just wanted to make sure you knew.

Your motherboard ground is supposed to be connected to the case. The AC (wall current) ground line is also supposed to be connected to the case. If everything is functioning properly and you are using all three prong (grounded) power cables, then you are touching your AC ground line when you touch the case.

I am not an electrician but:
If you're getting a jolt, then I would think that the problem would be with your AC currect ground line. If your AC ground line is messed up, then you have a serious (and potentially dangerous) problem. I'm not sure if a screwed up power supply could cause the problem. I would assume that it just has a direct ground wire from the AC ground to the case of the power supply and the computer ground.

dai · 01-27-2006, 12:33 AM

those are the standoffs and you need to line up the m/b so they all match,you cannot proceed any futher until they do
is the new case a standard size case,not a mini case

merged your threads,stay in the same thread for the same problem
do not start a new one
