Just a quick thought. I don't think anyone else covered this...
Have you tried another power cord? That has thrown me off in the past. Also once had the jumpers on the motherboard not set correctly.
Both of those kept my computer from powering up.
Watcher
I'll try this stuff tommorrow, but don't think its the power cord one who watches because I've been using the same power cord for another computer that does work.
Just curious, is that a A7S333 or an A7V333 ?
A7S333
OK ... first ... I believe the problem you refered to the first time was a problem with a P4 2.8 on an ASUS P4P800 mobo, etc ... that problem may, repeat MAY have been caused by you, ( Strange problems again ) but you sent it back and saidI am really WAGging it here:Quote:
I found a different company I think I will use. For an extra $15 they will put the whole thing together for you, and all you have to do is put the OS on. I like it this way because it something is bad then they will replace it before they ship it. All of these bad parts I've been getting is keeping me from getting these computers built for these people.
The motherboard you have is based on a SIS745 chipset, which came out for the Athlon model 6 chip, and auto configures the Vcc ( cpu core voltage ) based on what the cpu itself tells it.
My problem:
The Athlon model 6 utilized a normal Vcc of 1.75 volts. The XP 2200 is either a model 8 or model 10 which uses a Vcc of 1.65 volts. Neither the SiS site nor the ASUS users manual describes the specs on the Vcc for the SIS745 chipset, but it may not recognize the lower voltage because it came out before they were released.
If you used a company which put it together AND tested it, it should work unless, as stated before, you or the shipping company fried something with static. ( you've already ruled out the power supply ).
As stated in the suggestion in the suicidal thread, if you tested it without the cpu and memory installed, with the case speaker and external speakers attached ( IF your version of the board has the intigrated sound ) and you received nothing as far as POST messages, it might be the mb is bad. But I would first test the cpu ( on something like an ASUS A7V8X) and/or check your mb by using a Model 6 version ( something like a 1500+ or 1600+ which only used a Vcc of 1.75v) IF that is possible. I am curious as to the results.
Note: AMD does not list that mb as recomended for that cpu AMD Athlon™ XP Processor Recommended Motherboards If the company you purchased it from did test it first, send it back. If they did not, you may want to contact either ASUS or SiS concerning the compatibility with this cpu before sending one or both back.
Just my thoughts, again it is a Wild Ass Guess.
I found the same problem with another AMD Athlon XP 1800 +, it was a brand spanken new board and couldnt get a responce out of it. I sent it back over three times and still nothing but finally i had enough and told them i wanted a differnet board and sure enough it worked. other than that make sure your jumpers are set properly. if you have them set on reset CMOS the cpu will not start.
Other than IKnowNot's comments (bloody good info.. ) my only other thought is the BIOS isn't booting because of a M/B protection (see Iknownots comments) OR.. a strange lockup of the BIOS.. have we tried a full BIOS reset?.. some times the antistatic wrap can cause problems.. and a removal of CMOS Bat.. a shortting of the CMOS Reset jumper.. and (on some mo/bo's) a holding of a key on powerup (a extra software reset/restart).. this will be mentioned in the Mobo manual..
Cheers
i agree with jinxy, please try to remove the motherboard in its casing attach everything
then turn on... we have a lab with 45 units deployed by our supplier and 12 of them wont display just because the mobo was not properly grounded... or 2nd, try to check the heatsink at the cpu fan that it was properly attach to the processor.. btw, did you hear any beeps right after switching on the power?
I don't have another board to test the processor on, but I'll see if I can contact someone to find out if my CPU will work with that board. I thought it would work since it said that it has up to XP 2400 support.
Now the glitch with this company testing if for you is you have to buy the whole compuer system from them and then tell them you want them to put it together. They don't actually test the parts if your just ordering one M/B since their brand new.
When I get to my work place later today I'll try taking the board out to. and seeing if it will fire up.
btw: I built another computer which has the exact same specifications, but it worked fine for me.
I think I’m getting too much into the reasons and ignoring the cure. Sorry for any confusion.
If you can get it to start without the cpu, or with an older cpu check the bios revision of the board. That board DOES support that chip ( per ASUS ) but only with certain revisions.
