Old but re-jigged computer wont POST

[PaulPatterson]

Hi all,
just got a new motherboard and RAM and set it all up with all my old equipment that used to work. Now the computer does nothing
All the fans are working and the little front LED is on but the monitor's LED remains on yellow and there's no beep from the motherboard.
I have double-checked the pins on the motherboard where the chip sits and no pins are bent.
The RAM is a single stick of 1GB DDR2 RAM 5300 unbuffered and the motherboard is a dual channel motherboard but I think it takes single sticks.
The motherboard is an Asrock G31M-S

I have stripped the computer down, leaving just the mobo in the chassis with the chip and associated fans. No hard drives, ROMS, or RAM.
Without the RAM, the mobo gives 3 short beeps on bootup meaning a failure of the RAM. Upon placing the RAM back into it's slot, nothing as before, just the fans spinning. I've tried both RAM slots and the same nothingness.
Any help would be highly appreciated.

have you tried clearing the cmos

[PaulPatterson]

With it being a brand new motherboard I naturally assumed there would be no point clearing the CMOS

[glendalf81]

you should never make assumptions when it comes to computers lol, anyone on this forum will tell you that,
try that if that does not work ensure all jumpers which need to be open are open, a mobo i used a while ago would not post because i had a closed jumper which needed to be open, also check that the cpu you are using is supported by that mobo

[PaulPatterson]

Well I looked at the FSB jumper settings and they were wrong. I have moved them to closed/open/shorted (the opposite of what they were) and it's fine now.
Cheers

good glad you got it sorted

[PaulPatterson]

Oh well, maybe back to the drawing board.
My computer gets to POST then gets to the blue scrolling thing just before XP has finished loading and freezes when the blue thing is scrolling. It never gets past the blue scrolling thing
Any help please ?

i take it you are using the old hard drive, if so then you will need to do a fresh install of windows, as the old installation does not have the drivers for the new mobo, alternatively try and get into safe mode and install the mobo drivers that way, if you cant do that then a fresh install it is im afraid

[PaulPatterson]

I re-installed XP on a clean formatted drive, it only lets me to the desktop at the first instance of a new install. Upon a re-boot I get stuck at the scrolling thing. I can't get into Safe Mode as it sticks at the end of the list of driver installs.
