Help, my computer won't boot.

[Havoc151]

The other day my computer froze so I held down the power button to turn it off but now when I hit the power button it looks and sounds like everything turns on ( MB, hdd, graphics card, watercooling etc....) but nothing shows on my monitor ( the monitor works fine). And also now when I hold down the power button to turn it off, nothing happens, it won't turn off!
Please help, any advice would be appreciated!

Hmmm the 2 reasons i'd suspect would be...

1: PSU - not giving out enough power.

2: Graphics Card.

From what you've mentioned theres not much to go on at the moment.

You should tell us the specs of you computer, so we have somthing to go by.
Was it overclocked?
have you tryed reseating the ram and any other cards you might have on the motherboard eg graphics card, sound card, and cards?
unplug everything and plug it back in?
do you have the mother board manual? you may need to clear cmos

use the prosess of elemination, take out anything your computer dosent need to run, eg sound card or extra ram.

try to tell us about your computer

 

[troyrae360]

can you tell if its booting up? can you here the windows startup sound?
dose the computer beep at you when you turn it on? it it dose how many times? again check you manual, if you dont have one find the model of your motherboard and download it.

Have you added any new hardwear recentley?

Specs: Asus crosshair motherboard
3gig of mem
Amd 5200 black CPU (not overclocked)
Nvidia 8800gt (not overclocked)
Seagate raptor HDD
Watercooled
I have not added anything new to it!
I can't tell if it's booting, can't hear any beeps. Didn't even think to listen for windows sounds. I've tried taking all cards out and putting them back in. I put a different graphics card in with the same results so it can't be the graphics card.

unplug power cord, clear bios then try to boot with 1 stick of ram.

I doubt it but the gpu may have died. Can you try with onboard video or a backup card?

Try clearing C-mos to reset the bios.

Could it be your monitor? try the monitor on a different computer or a different monitor on the broken computer.

While powered off, reconnect all of the power connections internally, something may have jostled loose.

He mentioned he tried a diffrent card, i do agree on clearing the CMOS though.

it sounds like the motherboard if there is no beeps or any response the that's probably what it is

We shouldn't assume that he has a speaker connected to his motherboard... I don't hear no beeps at boot due to that very reason.

 

[Havoc151]

The monitor works fine, I reset CMOS by takin the battery out for 5min then put it back in. Same problem, still no solution.

 

[Dippyskoodlez]

What PSU?

And double check all power connections on motherboard (AND VIDEO CARD), reseat all memory.

Sounds like a weak PSU, or inproperly seated memory.

Id re spot the RAM check it first, then re spot the GPU, and if that doesn't work, ya Motherboard is dead.

Ive had this happen once before, it turns on, everything is moving, fans etc, but the screen stays black? means the mobo just died =/

 

[psyko12]

Could be the PSU not providing enough juice to the system. Try checking every connection as everybody else suggested. That happened once to my mate his PSU was dieing.

did you try to boot with 1 stick of ram?

 

[DaedalusHelios]

motherboard due to no error beeps.... also its an ASUS. Call Asus tech support for your region.

Ive had this problem three times recently and its been weak power supply all three times. Did your pc randomly switch off when playing games ever?

 

[Havoc151]

So I bought and installed a new MB, still nothing so I assume it is not my Asus MB. Is it possible that it could be my HDD, I don't hear it reading when I turn it on, and there is still no bios screen. The screen stays black. Any other suggestions?

well try unpluging your hdd then as your computer will still post with no Hard Drive

 

[DR.Death]

could the CPU cause this

 

[troyrae360]

could the CPU cause this

It could well be, i wonder if he's tryed each RAM stick separetley?
i think he tryed a diffrent vid card, so its probley not that.
so maybe the psu like a few ppl have alredy said

Im not sure, but wouldnt the fact that he bought and installed another mobo allredy account for that?

You have let us know what PSU your using.......It's very relevant in this situation..........it "sounds" like your PSU or CPU to me......I'm leaning more toward the latter though....do you have a spare compatible CPU around?
