NO POST! 2 different configs, old and new: 1700+ NF7-S, 3500+ A8V Deluxe--both died?!

[Sprocket]

this is crazy! i feel like 2 + 2 no longer equals 4; it just doesn't make sense!

specs:

configuration 1 and 2 share these same components
350 watt psu
tried both G-force 2 and 3 video cards
tried both PC3200 512 (2 X 256)mb Twinmos and 2 (2 X1)GB Geil Value ram


config 1
1700+ cpu
NF7-S mobo


config 2
3500+ 64-bit
Asus A8V Deluxe



config 1 is my old setup. it was time to upgrade. I put the new stuff in-- config 2--powered on, NO POST

so i put my old stuff back in, which was working just hours earlier with no prob, and powered on, again NO POST!

process of elimination hasn't got me very far yet. i've been trying every possible different combination to try to figure out what the problem is, and still am stumped.

this is killin me... I'm gonna even record and upload a windows media and quicktime video of the computer and stuff and what's goin on and post a link

[Gamer]

try another PSU, think that's your problem.

[Sprocket]

i surely surely hope that's the only prob, cuz that's one of the few things i haven't been able to eliminate yet. but, the fans and everything spin up, so i dunno. another thing that's weird is, about the first and second time powering on with the new stuff, i did hear a beep from the pc speaker, but after that, NO beeps with either the old or new stuff. here's that video, only windows media though--hope ya have it. http://www.lf7.net/noposthelp.wmv (about 4.45 mb) it's not very in depth; I'll prob make another one actually showing me powering it on or changin out parts or something.

[Sprocket]

It wasn't the psu. I tried the one from my dad's computer, a P4 2.5ghz and still no post. The fans spin up, you can hear the hardrives spin up if they're hooked to power, but no beeps come from the pc speaker, and nothing shows on the screen. it's so weird. i can hook up any combination i like and get the same results. i can hook up 1700+, NF7-S, 512mb Twinmos, and Geforce 3 and get nothing or i can hook up 3500+, Asus a8v, 2gb Geil, and Geforce 2 and still get no post.

here's what i'm pretty sure definately works:
video cards
ram
psu
monitor

so what could it be? this is so weird

[A Scream]

ok... since you grabbed a PSU from your dad's comp, and you know that works, switch parts out with that machine... Then you can be sure that the psu works and stuff...

BTW: nice pool table.

[Sprocket]

well, yeah basically that's what I've done. his computer is a p4 so i can't try out my cpu with its mobo, and i can't try out its cpu with my mobo and so forth and so on, but i did try its psu, which i know works because his computer still works with it. so my psu must be fine too except that I didn't plug it into his to see if it powered his, but it was powering mine with the same old configuration yesterday. see, i put the upgrades in mine, and there was no post, so i took the upgraded stuff out and put the old stuff in--now IT doesn't post either. the only thing that's the same between the two configurations now is the psu and case... it's like the only thing i haven't tried is putting the components into a different case--but how could the case have anything to do with it? I'll have to video the WHOLE process for ya. it's so freakin weird. it just doesn't make sense. the next thing I'll have to try is to see if i can borrow my bro-in-law's computer which has a mobo that will support my 1700+, so at least i can make sure that's still okay. other than that it looks like I'm going to have to order another 64-bit mobo, and if that doesn't work, another 64-bit cpu, and if that doesn't work i mean, that just wouldn't make sense at all. but if i ever do figure out what works and what doesn't, if i have any extra left over that DOES work i guess i can sell it on ebay or something. other than that, i don't know what to do.

oh and, aren't you supposed to be able just to hook up a mobo and video card to the psu and monitor and it post something like "no cpu" "no ram" and stuff like that???? cuz i can't even get anything like THAT to work.

[cirthix]

i hope your dad's comp isnt a dell... they use psus that will kill normal boards

[Sprocket]

it's an hp. *sigh* i guess I'll be videoing the whole process today start to finish and everything, so check back later

How many watts was the PS you tried(from your dads Comp)? What brand and Amp ratings is the 350? It may just be that niether of them have the power to run that system. The recommended min. for an A64 is 20amps on the 12v. After looking at the video Try hooking this up outside the case.

The 350
A8v & 3500
1-256mb sitck of twinmos
40gig hd
cd drive
GF2
See if that works. You'll want to set the board on a non conductive surface like a piece of wood or cardboard. It may boot with that config no promises as I have no idea what kind of ps it is.

BTW make sure you clear the cmos on both boards before booting them.

[Sprocket]

ok, but remember, my OLD stuff [1700+, NF7-S, twinmos, GF3] was working just fine the day before yesterday, and now IT doesn't work either. see, it was working, i took it out, I put the new stuff in, it didn't post, so I put the old stuff back in, now IT doesn't post... why would both sets of parts just quit working?? and i did clear cmos on both boards b4 tryin all this. I'll try again, and again... I'll take another video, and post back. i'm gettin a gateway 3500+ 827GM model today... does that mean it's definately a 939-pin socket?? and of course the psu in it will be a working psu rated for this stuff.

[Flannelman]

Its probably not both sets of parts. You have tried your dads PS with the old stuff right? I'm leaning towards the 350 dieing. You didn't say what kind, model, amps for either PS so I'm still in the dark there. The thing is if its a cheap PS they can work for a awhile and die hooking it to the 64 with is greater power requirements could have killed it. It sounds like one of the rails may have died. As to why your dads doesn't run it it simply probably doesn't have the power. I'd bet its a 250 or less being a 2.5 P4. So Its got maybe 14amps on the 12w which isn't near enough. If you can get your hands on a good working quality(350watt or better) PS I wouldn't be surprised if it worked.

You could try setting up a minimally configured rig with the old stuff also using the same list just subsituting the NF7-S & 1700 for the 64 and board. Though on the 350 at this point I don't really see either of them posting if it has a dead rail as I supect. One quick thing you could to is if you have a multi test the rails. by putting the red positive into the yellow lead on a molex and the black into a black lead. That will give you the 12v rail volts. You can do the same for the 5v rail by reading of the red wire instead of the yellow. Work on it and see if anything helps(or works).

[Sprocket]

hmm... yeah, it's starting to make sense now. i sure hope this whole power supply thing is the problem. circuit city wound up not having that gateway in stock so I'll have to wait till tomorrow to get a power supply... I'll post back then.

whoo! yes! 35 bucks for a 500-watt and it posted YAY! thanks so much for all your help ;) u guys rock

[i found nemo]

i can't watch ur vid's they freeze my computer

[A Scream]

Um... I reccomend a non-generic PSU. I had a 500W generic die on me under normal use w/o SLI.

QFT 500watts @$35 generally equals trouble

[Sprocket]

crap. so what psu do i need??
