Cant get a post screen on boot w/ ecs k7s5a pro

[eliteskillz]

I am unable to get a video signal with this mobo. I have tried multiple video cards: agp guillemot 3d prophet, agp dell geforce2, pci diamond viper v550 (all of them work in other rigs). I have also tried a 235w and a 300w PSU. I am using 2 sticks of PC133 Ram (256+128). Its beyond me what the problem is. I've built plenty of computers and never come across any problems like this.

There is power to the board all drives are spinning up fine and the network card is sending/reciving traffic. CPU fan is spinning and so is case fan.

Any Ideas?

ECS K7S5A Pro (Revision 5.0)
AMD XP 1800+
WinXP Pro

I assume that you're plugging the monitor in.

The only thing that I can think of is a defective motherboard. If it makes you feel a bit better, It's never happened to me before either.

I had a similar problem with a refurb mobo I bought from newegg... I had to RMA it and the new mobo came in and worked fine

Rule of thumb: Never use more than one stick of RAM when building a PC. Start with one stick, get the thing to boot, then add additional RAM.

That may not be your problem, but it's a good rule. Have you tried setting the BIOS back to factory settings and/or removing the battery for a few seconds?

I agree with M_Six, one sick of RAM to start with.

And clear the CMOS

Good luck

Is this a new motherboard? Have you checked to make sure all jumpers are configured correcty?

Had a new board shipped to me once that had the reset CMOS jumper set for clear rather than normal operation.

Hey thanx for all the replys!

This is a brand new mobo just purchased yesterday. I tried clearing the cmos (even though it should have already been set to factory defaults since i just plugged it in), but nothing still. I just plugged in the pc speaker and noticed im not getting a boot beep.

I read somwhere that somtimes this board will run out of a case but wont runn in one if the screws are too tight so i took it out, just for testing.... but still nothing.

I've unattached all drives hoping to get a post screen atleast but still nothing.

Just tested it with a old AGP 8mb ATI All-IN-Wonder rage pro....
still nothing.

Made sure cmos jumper was set to normal... no post screen still.

Just tested it with a new monitor .... still nothing.
(on this monitor I get to watch an anoying as !(*^@ bouncing "NO SIGNAL" graphic untill I can get this working )

Any more ideas?

Is it a new case also? Is the voltage setting on the back set to 115 and not 230? That was one of my bumbles one time. It would spin up all the fans, light would come on on the mobo, but no beeps or post.

I've purchased two k7s5a pro motherboards from Fry's in Dallas, TX and I'm having the same problem as you are. I've tried 3 different video cards, 3 different power supplies, 2 different cases (like it matters but it was worth a shot), 3 different kinds of ram (one at a time), and 3 different processors (1900xp and 2 - 2000xp).

Everytime I turn the power on all fans work everything spins and seems to be powered, but I don't recieve any beeps at all and my video on the monitor flashes like it has no signal.

I've built a few computers in my time, not saying I'm an expert or anything, but I think I know what I'm doing.

I've also had people that build them for a living look at it and they could come up with nothing either. Everyone is saying that their might just be a bad batch of motherboards that went out.

I found this post on another newsgroup board:

Well I've used about 25 K7S5A boards in the past 18 months.
Never had a problem until Nov-Dec of 2002.
Then the problems started. Lost CMOS, unstable with PC133,
CMOS batteries draining in a day, lockups, etc.
Some of these boards worked fine at first, then problems
would appear after 2 weeks of use. I've RMA'd all the bad
boards (4 of 5 bought) and the replacements have worked fine.
It's obvious that there was a bad batch of K7S5A boards.
Will ECS fess up and admit.....probably not, they won't even
answer a tech support question.

I'm at a loss along with everyone else right now. I'll be going to Fry's again tomorrow to see if I might get a good one. If not, since I've bought all my equipment from them, I'm going to ask them to test it. I don't know how competant they would be at testing it, but I guess I can found out.

You might call me stupid for buying the board anyway, but after I returned the first one I and was in the return line, I saw 3 other people returning ECS boards (don't know the exact models). I then asked the return guy if they have a lot of ECS returns on motherboards, and he just laughed and said yes.

I'll try to remember to post again, if anything good or bad come of this.

Have you tried reseating the processor? Also, my EpOX 8KHA+ would not boot when I first got it until I changed the keyboard. Wierd, hu?
