[SOLVED] computer will not turn on

1910 Views 24 Replies 2 Participants Last post by  dai
hello
I'm new to this place and recently my computer just crashed on me.

basically, it will not boot up, it won't even get to the opening motherboard splash screen...

I am using a MSI k8n Diamond motherboard and the D-LED indicator light shows:

RED | GREEN
---------------
GREEN | RED

which, according to the manual, says:


"Processor Initialization
This will show information regarding the processor (like
brand name, system bus, etc...)"


but it also says that if the processor is damaged or not installed properly than all of the D-LED lights will be red.

I see a no signal message on my monitor and get no other problem indicators. there is one beep when i turn it on, which is normal.

could this be a HD issue or a motherboard issue or something different entirely? I'm kind of in the dark and any help would be greatly apprciated

thanks in advance.

Re: computer will not turn on

the psu has a max output of 410w combined 12 line amps are 32=available=24
see if you can borrow a quality 550+ to try in it with a min of 26a available on the 12v line
Re: computer will not turn on

would this have happened after 2 years of use? the computer has worked fine for that time with the current power supply unit.

oh and it does power up.
Re: computer will not turn on

when you tax something near it's limits in the end something is going to give way
we always recommend buying case and psu as seperate items

do you think this would be a good PSU to try?

sorry if my questions are stupid or annoying (it wouldn't be the first time :tongue:) but i am still kind of a beginner to troubleshooting and PC building in general :grin:
Re: computer will not turn on

no they are not a recommended brand it would do to check with but not to buy
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004&Tpk=corsair+550w
see if you can borrow one to check with first
Re: computer will not turn on

cant find one to borrow...might have to buy...would you suggest PSU in previous post?
Re: computer will not turn on

yes it's top quality
Re: computer will not turn on

I used that power supply...no change in behaviour...HD mounts and works fine in a 3.5 external enclosure.
Re: computer will not turn on

when it is connected to the m/b can you see it listed correctly in the bios
if not try a new cable on it
Re: computer will not turn on

nothing comes up on my monitor. like i said earlier in the thread all i can see is a "no signal" message so i cannot read the bios.
Re: computer will not turn on

have a look through these

reseat and redo the paste on the cpu with some arctic silver

are you still getting the single post beep
Re: computer will not turn on

well i cleared the CMOS and now i can see the bios.

new problem...I can boot up Windows with one RAM stick in there but I get an error message saying that there is limited virtual memory and instructs me to set up a paging file (the performance is also understandably very slow). when i put in the second RAM in I get a blue screen of death that only stays up for a second or so and i cannot read what it says. did the CMOS clear take away the settings for a second RAM stick? if so, how can i update that?
Re: computer will not turn on

run memtest on the ram 1 stick at a time with it in the slot closest to the cpu

Re: computer will not turn on

I cannot get memtest to run...i tried using the USB thumb drive version and the ISO CD drive version and neither of them boot ... i either get a non bootable device message or i get nothing and it goes right to windows.
Re: computer will not turn on

have you set the bios to boot from cd first,before trying to boot from the cd
Re: computer will not turn on

yah but for some reason it must not have liked that CD so i burned another and it is working fine...do you just want me to post errors when its finished? or is there anything i should report on top of that?
