I just assembled a pc. I start it up. It briefly starts up and than immediately shuts down. HELP PLEASEEE!?

Question

Any error messges? POST code beeps? Does it boot into windows or start to boot? What are the processor temps in BIOS?

No error messages, no beeps at all,. it doesnt have windows installed yet. I cannot get into bios because it shuts down before that.

Answer 1

This could be loose RAM. It could be a bad processor. It could be a loose Video card. It could be incompatible RAM and Processor combination. It could even be a bad motherboard.

Try different RAM. If you have two RAM modules, try it with just one, then the other. Try a different Video card. Let's just hope that by swapping parts that you get it working. First assume that there is only one problem, and swapping will do the trick.

Good luck and Happy Computing!

Answer 2

I had a problem like this with my current mobo when I first installed it. I tried everything, new power supply, all the components out, etc.

Try this (if you already have, then go to the next one):

1) Start with JUST the motherboard sitting on the box you got it in (not the static bag). Plug in the powersupply and use a screwdriver to short the power switch jumpers. Do you get POST beeps? If not, try a new motherboard (this assumes your power supply is new and working properly).

2) If you get the appropriate POST beeps (telling you the CPU is missing), then add the CPU and try again (be sure to power the power supply off before doing this of course). Do you get the POST beeps telling you that memory is missing? If not, the CPU might be bad.

3) If you do get the POST beeps, put your memory sticks in (leave the CPU in of course). Try it again. If you don't get beeps, your memory is bad or not supported by the board. (This was my problem partially.)

4) At this point, you should try the video card. If everything is working at this point, you should be able to get past POST and see the BIOS boot screen.

If somewhere above you tried a new piece of hardware (for example, the CPU stage failed so you got a new CPU) and it still fails, then something on the mobo might have fried or the mobo might not be compatible with the component you're trying.

My problem was that I tried a couple of sticks of OCZ memory on a Gigabyte mobo. When I traded those in for a pair of Corsair sticks (some of the best memory by the way), the bloody board booted just fine. Wasted all sorts of time getting to that point though.

Answer 3

No beeps at all? Not even 1 short beep? If not, it's not fully booting up! Process of elimination as suggested is the only solution I see. Go slow and trace every step!!

I doubt you're even getting to POST (Post Operative System Test) and that's why you can't get to the BIOS (Basic Input Output System) screen.

I'm guessing bad CPU or MoBo or something grounding out (shorting) that's not supposed to touch. Hopefully you didn't already fry something!!

Answer 4

Many boards have a LED readout that will show at what point the computer quits and what to look at, CPU, memory etc.
A quick shutdown may point to that you didn't put cooling compound (the best is Arctic Silver 2+) between the CPU and the heatsink.
It could also mean, your CPU is bad (had that happen on about 2 computers out of 20 I have built).

Answer 5

No errors or beeps? You got BIG trouble then! Somethin aint in the right slot! Did you connect the processor fan and is it connected to the proper mobo connector?

Answer 6

Inadequate Power Supply.

Answer 7

Sounds like your "heat-sink". First, check your fan (you might need a bigger one). Second, get some "thermal grease" and apply it in a very thin coat. If that doesn't work, you may need to just pull the heat sink off altogether- you might sacrifice faster performance, but at least it'll run...

Answer 8

something isn't connected the right way, you're going to need to start with the motherboard itself and make sure its not touching any metal where it shouldn't be, then check all your connections and make sure they are seated in all the way, check your power source and be sure its working, check your memory and make sure thats seateed in all the way.
If the problem persists you're gonna have to go through a process of elimination using a working pc by swapping out parts and making sure they work, one by one.

Answer 9

I had this problem, or something like it. My CPU chip wasnt seated well and it didnt have a heat sink. If you have a parts computer grab the heatsink and lock it down tight.

Answer 10

Make sure that your ram is all the way down in the slot.The best way to check them is.That it completly out and re install them.
