K8N-E won't post, display, hardly budges the fans.

moonphrogg · 06-17-2005, 08:50 PM

So, I just got a new motherboard (Asus K8N-E Deluxe) in the mail today, and I installed into my wife's computer along with a new processor (Athlon 64 3200+) and a new heatsink and cooling fan. The case, hard drives, cd and dvd roms, video card (ATI all-in-wonder) and wireless network card have been taken from other computers.

So, I get everything put together and turn the computer on. Noticing that power was running through and everything seemed to be functioning properly, (all fans running, computer boots and posts), I quickly flip the computer off and connect the monitor, mouse, speakers and keyboard. I turn the computer back on, it boots, it posts, and then it asks me if I want to run the computer in safe or diagnostic modes (since I didn't let windows boot last time). I tell it that I just want it to boot windows normally. Everything seems to be going well until 10 seconds later, the computer shuts down completely and I can't even start it again.

All that happens when I hit the power button is each fan budges and then nothing.

Here's what I've tried:

Reseating EVERYTHING (multiple times)
I've taken the heatsink off the processor to check for contact, cleaned and reapplied thermal paste and mounted the heatsink again
I've tried booting the computer with nothing attatched except for the processor (also tried booting with processor and ram; processor, video card and ram; and everything)
I've also tried booting the computer minimally (processor, ram, video card) with the motherboard outside of the case, resting on a wooden table.

All of these have delivered the same results. Fan budges, then nothing (but the LED on the motherboard stays green whenever the power supply is switched on)

It's not the 4 pin 12 volt connector either. I have that connected to the motherboard.

The thing that gets me is that it worked until I tried to load windows. . .any ideas?

Additionally, I feel fairly competent in working with hardware. This is not the first computer I've built (although, it's the first with an AMD processor).

Thanks for any help!

I forgot to mention that I also tried clearing the CMOS, both with the jumper and by removing the battery-this didn't make a difference either.

have youn another p/s you can swap over to check if that is the problem

moonphrogg · 06-18-2005, 01:15 PM

Could it still be the P/S when the motherboard is still getting power? (the LED on the mobo still lights up when I switch the power supply on.)

Well, you hit the nail on the head. It was the power supply. The power supply I had in the machine was a 400W powmax that came with the case. I've never really messed with power supplies, so my questions might sound a little novice.

Firstly, could it be something as simple as replacing a fuse? Should I even try to open up my power supply and mess around with it?

Should I look at getting a different power supply? This is what I'll be running on the power supply-

K8n-e Deluxe mobo
Athlon 64 3200+
ati all-in-wonder 9000
d-link 802.11b wireless network card
2 hard drives (one 13 gig, one 40 gig)
a dvd-rom
a cd-rw burner
3 cooling fans (one has a nifty cold cathode on it)

Is that enough to overpower a 400 watt power supply? And if my power supply is shot, what should I be looking for? (that's relatively affordable)

Thinking about picking up this one:

Man if only the power supply companys did as good a PR job as the CPU companys have!

I am not harrassing you by the way :) been here myself!!!!

The power supply is the most overlooked important feature ignored by puter parts buyers

I would strongly suggest you buy a minimum 450 watt NAME brand power supply and a good one Antec or Enermax 550 watt is even better
a good power supply is $100.00

The new systems are EXTREME power hogs / and worse than that / if they dont get the right constant juice they will burn a cpu and gfx card to toast from low voltage resistance

the poor quality PSU dont put out what they say they do and they are erratic in the constant stable power dept. You need about 60% more wattage than your system specs "seem" to call for / this is because you dotn want to be holding the pedal to the floor on your PSU all the time its running.

If we only knew the vital role the power supply plays in todays systems !!!!!!

hope this helps ya

regards
