System Spec:

Foxconn NF4K8AB-RS (new)
PowerColor x600XT 256MB R38-TD3 (new)
2x 512MB DDR400 Ram (new)
Tagan i-Xeye 420W-U02 PSU (4 mnths old)
Benq DW1620 Pro DVD-Writer (4 mnths old)
BTC DVD CDWR Combo (1.5 yr old)
40G + 8G HD (1.5 yrs old)

your psu is not enough you need at least 450 +

im getting the exact same thing and im overclocking the 3000+ to a 3500+ yea ...

people have told me under 450 Watts doesent work

and it has to have good voltages

ok...

any suggestions of good PSUs for nForce 4 boards?

I ended up getting an enermax 550 psu.

pc power & cooling turbo-cool 510 express
enermax noisetaker 600w

Lol just get a cheap "off-brand" PSU. like 600w.

there like 10 bucks. and do a good job.

...... ChiefMax...right?

what do you guys think of RAIDMAX PSU?

Not very good for the amd 64 bit, I would suggest either enermax or antec.

thanks wild child

had a look around, i'm in New Zealand so prices are abit high down here!

came up to a Sprite 500W (UV) by JSP Tech for $122NZ Dollars

These 2 look to be a better choice out of the ones available to you.

ok guys! assuming the 420W isn't powerful enough i tried this:

disconnecting everything from the mainboard and PSU except the

1) Mainboard which hosts the PCI-E Graphics (Radeon x600XT 256MB), RAM, and CPU
2) One Hard Drive which has Windows Xp Home already

Boot-up the system runs fine, when i restart it won't start up again. The computer is running coz all the fans are going but nothing on screen.

To solve this i have to fully turn off the system from the wall, or reset CMOS. Doing this enables something to be showed up on the screen...

has anyone experience this before? do you think its my PSU? (its a pretty good one)
i'm having this feeling it could be the board itself, maybe corrupted cmos or something

I would check for a bios update also, then I would pull out one stick of ram and boot the system. But more then likely the 420
isnt strong enough.

WC

ah huh! got it.. thanks wild child

it was actually the memory modules that screw up the system... installing two of them for some reason stuffs up the booting, now i'm just using one 512 module... these are non-branded RAM modules bur i guess" one pays for what one gets"

cheers!

Glad you got it sorted,

WC

flashed with latest bios update and solved the whole problem now my lil' beast is going well

cheers guys and thanks Wild Child
