[neil]

i have an iqon pc with gigabyte s651 mprz with 2.66ghz p4 processor.it only has 256 pc2700/333 ram stick in on xp home and i thort id pop another ram in just to speed it up a bit,i got the same ram and it didnt make any difference so i took it back out.now the pc wont post nor boot up.when i switch it on the power comes on and the fans run and it wont turn the moniter on
things ive tried -bigger psu,different ram,gfx cards,moniters,h/drives.resetting bios,new bios battery

i spoke to someone who i thing has one thing on his mind and thats to sell sell sell he says ive sparked the mobo and need a new one i have another mobo that does the same and no somone else with the same problem surley they cant all be sparked???

that is strange, given that you have replaced almost all your components. the same happened to me and i reset the bios (battery out for several minutes). If you have any external graphics then remove it and reset your BIOS back to running internal. need to do some more digging then ill get back to you

[neil]

yes tied resetting bios took the battery out even replaced it with a good one with just a little over 3volts,i have another boared that does the same its a micro star ms-6541 ver 1.0 with p4 1.7ghz processor and tried diferent ram in that too ddr 2100/266,2700/333 and 3200/400,same thing and also my mate has one do it to and thats an athlon set up,its loke the board turns the moniter off

Just a quick check dose the machine post beep if u remove the memory from the banks then run the machine.Also u say u have tryed another graphics card i guess u must be running agp for those kind of processors have u tryed placing a pci standard card in.

See last time i had this,it came down to memory both sticks seemed to of died so i placed new memory in all worked fine.

One other thing if as a last resort, people never belive in this, but take the pc fully apart, processor out of the motherboard,also bios battery leave over night so the board has no power or anything init.So any static or power will be around the board also makesure when placing the board back in fit the rubber rings around the screw slots in the case to stop any sparky lol.

[neil]

no the iqon will not post with or without ram and have tried pci as well as agp grafix card i suppose both rams have gone never thort of that it would make sence as alls i did was remove one and coulda sparked the other only prob is i aint got anymore to try(got lots of pc100)no ddr,and dont want to spend too much on ram to find it might not be that

the microstar board however gives 1short beep which i do think is a post and then 2 longer ones,the bleep codes say 2 means parity cannot be reset whatever that means and 3 means first 64k memory failure

i will strip the iqon right down to nothing and try the overnight thing and see,in the meantime i need to source some ram,

thanks to you guys 4 the info so far

hi mate if u send me your e-mail address,i wouldn't post it up on here,just incase of spam or anything.U can e-mail sales@jtechcomputing.co.uk then i will send u a invoice,then u can pay throught their mate.Thanks

[neil]

new news i stripped the full pc down left it overnight etc,built it back up no change,APPART from i found the pc has no speaker in so i installed one and when i switch it on there is one long continuous beep from the speaker

any thorts??

[Budget-IT.co.uk]

oops this suggests to me there is a power supply problem or something as small as a keyboard fault. Worst case here is that your MOBO has shorted

[neil]

probably the mobo then cause iv tried all the other stuff power unit,keyboard etc

[TheComputerGuy]

I had a similar issue once, the mobo was shorting out on the chassis so i took out the mobo and placed in onto some cardboard and started it up. This worked for me as i then inserted some rubber washers behind the screws connecting the mobo to the motherboard. Not sure if this will help but it worked for me!

[neil]

thanks ill try that,the thing is tho it was fine untill i removed a stick of ram nothing else was disturbed and there are no rubber rings on it so if this does work ill have to buy some
