firtsly this is whats not happenning..system will not post. no display no beeps current setup. gigabyte 7n400s-l athlon xp 2800 (barton) not OC) onboard sound nvidia geforce 6600LE agp (256mb) 256mb pc2700 viking ddr 80GB maxtor HD hardware has never been used. used anti-static strap when handled components. clock sw is set on = auto master/slave ok using 2 IDE cables monitor works with other pc (working system that is) all fans are whirring, i think mobo is ok cause the cpu fan receives pwr from it. what could be wrong...
disconnect all cables to drives. remove all cards except for videocard & 1 stick of ram. reseat videocard & stick of ram. make certain cmos jumper in default/normal & not in clear mode as seen that a few times. clear the cmos with the jumper as might kick start computer, done that a few times.
In addition to ddp's advice, remove your heatsink, and check to see if the CPU is seated in the socket correctly. When putting your heatsink back on, make sure you clean each surface well, and only use a drop sized amount of thermal paste. It's really easy to over do it on those CPUs since the core's surface is so small.
how do i move the jumper exactly, i thought i just had to push it...it wont move, i dont wanna break them..whats the trick? theres only two pins on my cmos jumper but the diagram shows 1-2 clear cmos, 2-3 normal ?
Different motherboards have different ways of clearing the BIOS (CMOS) chip. 1. Leaving the battery in. Remove the jumper from 2-3 by pulling up on the jumper. Place the jumper on pins 1-2, leave for 5 seconds, then remove and put the jumper back on pins 2-3. 2. Taking the battery out. Then, proceed with swapping the jumper as mentioned in step 1. 3. Simply removing the battery for 5-10 seconds. 4. Touching the CMOS CLR tabs with a flathead screwdriver. Some motherboards don't have the jumpers, instead they have solder points. It's best to read your motherboard's manual for the correct procedure.
manual only says to short 1-2 pin, and that it doesnt include a shunter...the diagagram on the board differs from that. i cant move the jumper two pins 2-3 cause i only have 2 pins, thats wots confusing me..on the board looks like there should be a third pin but isi'nt. just a little metal thing like a solder point. the board was set to clear cmos when i bought it...so now i wanna shift it to normal, or else its not going to post. goin to play about with it some more..
if jumper was on clear mode than computer won't post at all so position jumper on normal mode even tho only on 1 pin so don't loose jumper.
to short the pins you just need to get a flat piece of metal (ie a flat tipped screw driver) and place it over the 2 pins for a few moments. if it was set to clear when you bought it and it was working then, setting it to normal isnt going to do anything. personally id say the your mobo has died a death like mine probably will do soon but without another a processor to try on the board its going to be difficult to tell
My mobo never had a jumper on the clear cmos pins. and doesnt require one to function properly. to short the pins you just need to get a flat piece of metal (ie a flat tipped screw driver) and place it over the 2 pins for a few moments. if it was set to clear when you bought it and it was working then, setting it to normal isnt going to do anything. personally id say the your mobo has died a death like mine probably will do soon but without another a processor to try on the board its going to be difficult to tell if you can set the clock to be 333 (thats what it should be for a 2800) and not auto as auto usually means 100MHz and that could be why its not funtioning
yeah it was set to clear when i bought it but it didnt work then and after all everyones help (appreciated by the way) i still cant get it to post, so maybe ur right the mobo is dead, (although its powered any chance its the cpu or the battery dead? may take it to pc world. thanks p.s on gigabytes 7n400s-l the clk sw is set like this on=auto off=force 100mhz (thats why i set it to auto)
Ok, I looked up your mobo on Gigabyte's website, and to clear the CMOS on that board: Unplug power cord from PSU. Remove the battery. Wait 10 minutes (usually less than that though) Replace battery. Plug in PSU. For normal operation, you shouldn't have any jumpers on those pins. It also states that you can clear the CMOS by shorting the two pins. (using a flathead screwdriver, touch the two for about 5-10 seconds)
thanks morph, i have tried clearing cmos several times by removing the battery(for 30+mins) and shortin the pins, but it still didnt work i also tried a different vga card, and ram(not sure why i did that). so yeah u lot are propably right mobo is choked, im sure ive tried everythin i can...so ill just see if i can return it.
I thought I'd killed my computer when I was playing around with PCI cards and IDE cables the other month. Turns out that I had pulled the power cables off of the motherboard to give me some better access, and when I plugged everything back in, I forgot about the 4-pin power cable that isn't a part of the big chunky ATX 20 odd pin connector. Moral of the story: check that every plug is plugged in! You might have missed this one like I have, everything looks like it is going, but the computer goes nowhere...
just to let eveyone know...i got the dam thing working..not sure why it started posting now, but this is what ive just been doing since my last thread update, stripped pc down (completley)removed mobo then remounted it, attached and checked every cable twice, then for the hundreth time it seems i tried clearing cmos every possible way in a random order, and then i tried firing it up for the last time i was ever going to do it, and it beeped once..post displayed and wallah..how interesting. since i dunno much bout computers, i cant say how that happened. but its great and thanks. just gonna try gettin it to pick up the right cpu speed and manually input the hard drive.
