[SOLVED] Old but re-jigged computer wont POST

PaulPatterson · 06-28-2009, 04:03 AM

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.

Do a bench build and we should be able to narrow down the problem:

Bench Test Your System

I have since stripped the comp down to the basics to be able to see what's happening, basically I removed the CD-Rom and cables. It booted no problem, I rebooted just in case it was a one-ff but no problems again. So the issue must be CD-Rom related.
However I have in the recent past tried another CD-Rom and other cables and got nowhere.
What can I do, I need a CD-Rom

Can you borrow an optical drive to be sure that is the problem?

Up until 10 minutes ago I had the hard drive connected to the motherboard IDE and the CD-Rom connected to the IDE card in a PCI slot, a logical choice in my opinion. I tried slaving the CD-Rom but that didn't work and isn't a good option anyway.
I have now altered them around so that the hard drive is on the card and the CD-Rom is on the mobo, and it's all working fine now.

Great, if it isn't broken that way, don't try to fix it. Enjoy the week with a working computer.
