stuck in a reboot cycle again

[idimmu]

hi all

left my computer on last night, only to wake up this morning to find it off.. i was confused and when i tried to turn it back on again i got nothing. i unplugged the power cable and held the power button down for 20 secs, plugged it back in and it booted fine into windows... for about 30secs, then you hear it click and reboot. it will then proceed to get to random points in the boot and click and reboot. after a while it will give up and stay off, and be unresponsive.

i have tried resetting the cmos several times, tried changing the bios settings (most of the time it will reboot itself while im trying to change them). i get no beeps whatsoever. i get an array of error codes off my motherboard, ranging from 9F to FF, which mean incompatable power supply, and normal shutdown respectively.

im totally confused as to whats gone on? my machine isnt overclocked, and never has been, and its been running fine and stable since i built it a year or so ago. i guess something has fried? but im at a loss as to what?

any ideas?

thanks

specs all at stock speeds:

abit av8 s939 agp
athlon 3500+ winchester
x800xt
2x512 crucial ram
hiper type r 580w psu
3 hdds, 1 optical
audigy2
wifi card

forgot to add: ive done a lot of google work, and a lot of problems with this board came up with incompatable psu as the main reason for not booting, but as i said mines been running fine and dandy for a long time :<

have you ran a chkdsk from the recovery console ?

[idimmu]

it wont stay on long enough for me to get far enough to do that. right now it just keeps turning off with the error code 9F on the motherboard after about 5 secs of being on. ive googled this code a lot and it means incompatable power supply, however, if my psu was incompatable, i would have got this error the first time i tried to turn on this machine when i built it over a year ago

bios update or borrow a PSU ?

[idimmu]

looks like im gonna have to just keep changing bits to find out whats gone argh

For me either your PSU is failing or something is getting very hot very quickly. Is it possible to clean up the CPU and apply some fresh thermal paste?

ive tried reseating the cpu to no avail.. is it possible for the psu to take a dive just like that? seeing as now, it is again just powering up for about 5 seconds then restarting itself.

Almost certainly the PSU. Potentially a fan stopped spinning though.

[idimmu]

ive tried to set it in the bios to not stop for cpu temps/fans/etc but im not sure if it sticks as it often dies before i can even set it and save it.


i guess i'll try to get a psu from somewhere see if it helps

thanks gus

It's entirely possible for a PSU to do this - any piece of hardware can fail and usually they give little warning. Did you apply new thermal paste to the CPU when reseating? As shaithis said can you check to make sure you don't have any fans that aren't spinning?

[idimmu]

yeah i applied new paste, and all my fans are still spinning fine, was a bit dusty but ive got rid of all that now, and its still the same

[unxetas]

looks like either a PSU problem or a short-circuit somewhere on the board.. being drilling any holes recently? Is the motherboard using all the (usually) brass riser thingies?

[idimmu]

new problems :

i got a new motherboard and installed it and after fogetting the 4pin (who invented these -_- ) it booted fine into windows...then i restarted and booted into my debian system to have a play around, configured a few more things, had the machine on for about 2 hours fine, went to reboot and now it wont post again. all my fans spin up harddrives make noises but nothing comes up on the screen, much like if you forget the 4pin. the new board is an asus a8v

is my psu shot?

thanks

I would definetly think so based on what you have said. it definetly points to a PSU issue, and with those Hiper's alot of people have found them slightly flakey so it wouldnt suprise me.

the only reason that it might not be, is that you said it was fine while you were on for 2 hours, and then im guessing you turned it off and now it wont post, that is possibly a motherboard issue, but still could be PSU.

[idimmu]

after installing this second board, ive done one shutdown which was fine, and 2 reboots... it was on the second reboot where it didnt actually reboot, rather just shut down the OS and then hung, fans spinning and everything and just stayed there. so i manually switched it off, and now this is all it does.

i think im just gonna spend some money and get a new psu

[tigerboyce]

or get a friends to test first?

hope it works though
