my_computer · 9 Jan 2008 at 19:32

just built pc. it goes on for about 20 seconds doing all the usual things. after a little while it turns off. this happens everytime. any ideas?

my friend suggested unplugging certain things and trying it without them in. any other ideas?

my_computer · 9 Jan 2008 at 19:47

i get a message whilst booting saying "cpu is unworkable or has been changed. please recheck cpu soft menu." is this normal as i'm using an old hard drive??

my_computer · 9 Jan 2008 at 20:19

i unplugged the cable that goes from the power supply to 'atx12v1' on the motherboard.and the monitor does nothing but it stays on. any ideas?

did your old hdd have a copy of windows on it?

in the 20 seconds is there any attempt to boot into windows?

my_computer · 9 Jan 2008 at 20:27

yeah it has windows on it. and it can get to the bit where windows starts to load

my_computer · 9 Jan 2008 at 20:31

if i press F1 it continues to load windows. if i dont press it it stays at another screen and then turns off at that point. sometimes it turns off after a few seconds.

its most likely that windows didnt like the mass hardware change, i suggest reformatting the drive and putting a fresh install in

my_computer · 9 Jan 2008 at 20:34

ok will try now

my_computer · 9 Jan 2008 at 20:35

would that explain how it doesn't turn off when i unplug the cable that goes to atx12v1

my_computer · 9 Jan 2008 at 20:37

also remember that it turns off before windows trys to load.. so maybe a format isn't it?
i dont know you know more

jak731 · 9 Jan 2008 at 20:37

im not sure on that one sorry, reponse to post 9

for post 10, its normally recommended that when do change a lot of hardware, you reformat as it stops a lot of potential problems form occuring

my_computer · 9 Jan 2008 at 20:41

if i unplug the hard drive then turn on it still turns itself off

try puttign the ram to 2.0 volts as thats the defult for that ram

my_computer · 9 Jan 2008 at 20:49

(turns off when i'm in bios too)

my_computer · 9 Jan 2008 at 20:53

changed ram to 2.0 seems to be worse now

not managed to get back to bios since changing

It sounds like it might be switching itself off because it's getting to hot. Make sure you have good contact between the CPU and heat sink.

It is advisable to a rebuild after changing that much harware though

my_computer · 9 Jan 2008 at 20:55

ok managed to get into bios . its deffinatly changed to 2.0

still goes off though

my_computer · 9 Jan 2008 at 20:56

temps in bios seem low for the cpu
