UPDATED:FINALLY FIXED, Faulty HSF wire and temp sensor

🙁

So yesterday I gave my yearly maintenance with a can of air to my rig:

A7n8x Deluxe (rev 2.0) 1005 bios,
2100+ AMD Tbred B
Antec PSU 430 true power
1024 Ram
9500 pro
etc... I can add more details if it'll help.

and I also tidy'd up the cabling as well using cable ties and rearranging the power cables to clear up the clutter. I took apart the each ide device and cleaned it thoroughly. Only IDE cables/psu cables were detached. Everything else was left intact.

I put everything back together and it booted up into winxp and everything was nice and peachy. I went to do something and when I came back (~20 minutes later as the clock struck midnight), I noticed that I wasn't getting a video signal. At first I thought it went into hibernation but it wasn't so. Rebooted several times to find out it won't even post (not a single beep). So I cleared the CMOS (removed the battery and resetted the jumper), nothing.

Unplugged everything and tested using basic components: vid card, ram, keyboard. It still won't post.
Tried everything possible cept replacing the mobo/cpu (no spares). I still get a green LED on the mobo when plugged in and that's about it.

So anybody have suggestions as to what the problem could be? PSU? CPU? mobo?

Argh and happy new year. 🙂 Typing on a spare comp (celeron).

UPDATE:
Finally got the RMA back and they said nothing was wrong with the mobo. Guess it might be the CPU then.

Update 2/22/05:
replaced barton, no dice. 🙁

Update 2/24/05:
discovered mobo works because video card wouldn't output a VGA signal so computer wouldn't post. But it rejects the RAM that was used in the system for almost 2 years. What the hell is going on?

Update 2/27/05:
FIXED with original cpu and mobo, had to replace faulty hsf wire and tempsensor. 🙂

THX guys for all the help, I was about to break down and buy a p4 or dell or macmini. 😀
 
My guess- it's just something not plugged in right, unless you snapped a pin off or something.

2 days ago I got some new uv reactive cables and switched out some of the old ones. Then later on I booted up and my harddrive started making noises, and Windows froze up. After that Windows wouldn't load, and the noises got worse. My first thought was to go to my other pc and log in to Newegg to print my receipt and then call Western Digital.

When I came to my senses, I realized I had most likely just jarred a connector. I pushed all power connectors and data cables in snug, rebooted, and of course, it was fine.

Yea I just don't understand if it was a loose connection why it was able to boot up. Time to go over each connection again.

Thank.
 
Make sure memory, AGP video card (most often the cause), and CPU are seated properly. Also make sure your CPU fan is connected to the header marked CPU Fan. If you have one of those "CPU overheat protection" mobos, some won't start without a working fan with speed sensor on the CPU Fan header. If that was the case with yours, then you need to clear the CMOS before it will start again (make sure to turn off comp at PSU switch or unplug from wall before clearing the CMOS else it may not clear properly.

Checked and rechecked all fan connections. Tried another psu, no go. Can't even go into the bios.

I hope the mobo/cpu is still alive.
 
If you have your TP430's fan-monitoring wire plugged into the motherboard, or any other low-RPM fans that send RPM signals in the sub-2200rpm range, then unplug that monitoring wire and those fans from the motherboard's 3-pin headers.
 
If you plug some headphones or powered speakers into the green audio-out jack on the rear, does the onboard speech diagnostic give you any lip? 😀 Did you take off your heatsink in all of this, by the way? If so... fresh thermal grease, right?

haven't done the heatsink yet (assuming i have to replace the cpu or mobo). That's the last resort thing. Yep no onboard speech. It won't even post into bios with the beep.

edit: no spare cpu/mobo so no use taking off the heatsink (is what I'm thinking).
 
When you cleared the CMOS, did you remember to unplug the system too? If not, give that another whirl... unplug, remove battery, move jumper, reverse procedure. And naturally, eyeball the cards and RAM really closely to ensure they're firmly seated in their slots still.

cleared cmos several times unplugged (also had to move a jumper to reset cmos, moved it back as well)
removed ram-> put ram back in (to check if ram faulty)
removed vid card-> put vid card back in

also, checked out the psu/vidcard in an older computer (tbird 800) and they both booted up.

I did like your tip with the hollow end screw driver to remove the heatsink. I'll try that once I order a new chip/mobo.

thanks for your help.


I thinking the mobo/cpu is dead.
 
Hmm, you could drop in the old 800MHz Tbird, set your CPU_FSB jumper for 100MHz, and see if it fires up that way. If so, that seems to narrow it down to a bum CPU.

no fsb jumper for 100 fsb directly just 200 (which i assume is ddr so 100fsb effectively).

slapped on the tbird no go.

looks like the board is dead.
 
Darn 🙁 Abit NF7-S is a pretty close match, if you want Soundstorm and Firewire. Otherwise there's the Shuttle AN35N Ultra...

thanks for the trouble shooting. Yea I was looking at the nf7-s or the A7n8x-e deluxe, they are both good. I just don't want to reformat once I install the new hardware. I hope it's not a big jump going from one nf2 board to another.
 
update: replaced with barton, no post...

I'm really going to be pissed at ASUS for lying if I replace the mobo and it works...
 
Your keyboard's in the purple port, not green, correct? Tried it outside the case on cardboard with just the absolute essentials yet? Video, CPU/heatsink/fan, one memory module, power supply, and the case's power-button wire, nothing else (no keyboard, mouse, PCI coffeemaker controller, etc). On cardboard.

sadly yes 🙁

maybe i'm not installing some key essential component?

one hooked up HD check
Ram check
Video check (using D-sub not DVI with power cord)
Cpu check
heatsink + working fan check (using TT smart fan with own power cord)
power supply check
power button wire check
reset wire check
led/speaker wire check

no kb, no mouse, no cpu fan monitoring connectors are connected on mobo.

no BEEP, no post, no audio post, resetted bios etc... 🙁 Now I must return the chip and eat a 15% restocking fee from new egg. 🙁
