PLEA FOR HELP: Still no post after bios setting changes (A7V)

[velvtelvis]

Ok.

I posted asking about this a week or so ago, and am still in the same boat. I'm rather frustrated as I've got a paper on the hd that is due in a couple days and i really don't want to go around begging people to let me put my hd in their systems since i screwed mine up. Nobody sane should let me near their system with a screwdriver. Anyway.

Last week I changed a couple fo bios settings, rebooted, and the machine would post or go into bios safe mode or anything. It powers up, HD and CD power up, and i get a brief flicker on the moniter. No beeps or post or anything.

I tried disconecting the mobo from the PS, removing the cmos battery (the one by the via ata66 bus) and putting it back in. If I recall, I changed the speed of the RAM to 133 and changed the PIO mode on the CD. I had flashed to bios revision 1007 (final) a few couple weeks prior and had been having smooth sailing until this.

I tried removing all cards but video and still no luck. I re-seated the ram, no luck, etc. I'm at a loss for why this happened and what i should do no.

Any ideas?

System in question:
A&V set to jumperless
Duron 600 @600
256 megs muskin/infenion (sp?) (128 x 2)
atiAIW 128 (2x AGP, fast writes off)
quatom fireball lct10 10.2 gig HD on via bus
POS mitsumi CD-RW
AMD approved 300W PS

modem and sound card removed to eliminate any compounding variables.

I'm stumped and stuck on my gf's imac, and right about now I'm feeling like deserve to be on an imac.

Oh, ATX soft-off won't work, but it shuts down fine when i hold the power switch down for a few seconds.

i think theres actually two solder points on the a7v that need to be shorted in order to clear the bios.

 

[velvtelvis]

pulling the battery wouldn't do the same thing?

how do i do that, exactly, so i don't fry it?

 

[Duvie]

do a search for "amd not impressed" in this topic...A guy yesterday had problem of overtweaking bios and it would not post and many talk about way to clear cmos bios back to default by shorting two sodered points...check it out it may help

Use a screwdriver and touch both solder points to clear cmos. I dont see how you could fry the motherboard without even turning it on. You could also put your board in jumpered mode and set everithing from there. I have the A7V133 and just cleared my cmos. Aparently my tbird wont post at 1200MHz:|.

Ok, I connected the points with a screwdriver with no luck.

I did it with the machine off and mobo unplugged from the PSU. Acording to the manual, doing such resets the RTC RAM. This is the point i wanted to connect, right?

Would using the jumper settings make a difference since there is no jumper for DRAM frequency (the setting I changed that resulted in this) on the mobo? or is there?

I'm half blind and short on lightbulbs, so i'm reluctant to play with jumpers until i can get better light.

When I changed this setting in the past, it simply went into bios safe mode. This anoyed me as i was under the impression that i should be able to run it at 133.

Could changing this setting have damaged any componets?

I really don't want to try each componet individualy in a seperate machine.

Should I tuck my tail between my legs and find someone to hot-swap the bios?

This is a long shot, but have you tried a different stick of ram? I had a similar situation and it ended up being a flaky stick of ram that was the culprit.

 

[Boonesmi]

if you have the manual it shows how to clear the cmos with shorting the two solder points

 

[velvtelvis]

well it didn't work or fix the problem or whatever

grr

Put the hard drive in someone else's system.

It's not the video card, that produces endless beeping on most KT133A's, ditto with the RAM. Can't be power supply, because with everything disconnected, it would at least post, probably crash in Windows if it was *that* bad.

It's either the CPU or the motherboard. Check the CPU, did you ever notice a burning smell or is it charred or cracked? Also, the motherboard might be dead, have it RMA'd.

Edit: "I'm half blind and short on lightbulbs, so i'm reluctant to play with jumpers until i can get better light." Check your jumpers!! That's the easiest way to make a board malfunction, anything from power button to bootup to performance can be affected..
