[imported_tkkidd]

hello all this is what i have

Shuttle an35n ultra 1.1 rev ( laterest bios)

amd mobile 2500 barton

mushikin ddr400 at it's speed 2-3-3-6

cheap 300 W power. by rosewill

Prime ide wd 80gb, wd 120gb

sec ide dvd rom, cd-r drive

fans...2 intake 2 exuast fan... 32C / lead ~50C




my problem.

Once it's on it works just fine for hours.

I over clocked before to 2.2G ( 200mhz * 11)
or 2.3G (200mhz * 11.5)

But some times it just wont boot up right, The bios start at the safe mode

displaying

"amd mobile 600mhz..."


What i do right now to get by is....go into bios and save and exit.

when it restart it seems to work SOMETIMES.


Am i doing something wrong with voltage???

for the chip i mess around 1.7 volt~ 1.775 volt...

for the memory i only have 2.6 and 2.7 volt option ....



Do i just have a bad motherboard??? how come my computer is stable once it's on
(ex. setting - 11 X 200 1.75V 2.7V for the ram.) but i can't boot it up????

kidd,

Welcome to the Forums! :beer:

Are you saying you only get these problems when your CPU is overclocked?

Regardless, the one suspicious item you mentioned is the Rosewill PSU.
Can you borrow / beg / buy a higher wattage & higher quality PSU to try?

With all of the stuff in your machine, I'm surprised that PSU even works at all.
