Abit NF7-S Rev 2 board

[cromwell134]

Hi
I hope someone can give me a clue. I have a new NF7-S. Put it together last night with Athlon XP2200, 2 Samsung PC2700 256MB and a GeForce FX5500 with128MB RAM. PLugged in a hard drive, DVD and floppy. All this kit worked with my previous set up. When I turned it on, it spins up for a few seconds then just shuts down. And makes a noise like an ambulance in a hurry!!
Can anyone tell me where to start looking? I don't really want to start replacing parts willy-nilly as that could get expensive.....

Cheers

ck that your ram is fully seated and your processor is installed right.sometimes those ram sticks go in really tight.
if that doesn't do it i'd,go to 1 stick of ram, unplug everything off the board i could to try to isolate the problem.

the first thing to try is the psu.
In a situation like this, tracking down the culprit is very difficult. I usually strip the system down and put it together peice by peice. Disconect everything apart from the psu and motherboard, no cpu, no memory, it should at least power on and maybe beep some error codes out, next try the cpu, then memory 1 stick at a time, then the vid card, then the hd, flopppy and finally the optical drives
doing this most of the time for me the problem has just gone leaving me wondering what the hell it was in the first place, but fixed is fixed

Sounds like an ATTP1 over temperature protection controller. As Attansic are proud to claim "Siren Blares Once OTP Is Triggered"! You might want to check the seating and thermal interface of the heatsink.

Àedán is right. That is the classic OTP failure alarm. Generally it is caused by the CPU getting too hot due to a poorly mounted heatsink. SOMETIMES, though, it is caused by screwy CMOS settings giving you a bad overclock. Check your heatsink mounting, and make sure you have a proper application of thermal paste. If all is in order, reset your CMOS memory.

Thanks guys. It was the heatsink. Now all sorted....

Watch your temps/voltages in bios setup after a new system build, I'ts a lot easier to spot simple malfunctions that way before you find that Windoze doesnt completely install.
