A7N8X shuts down after 3 seconds

[volt]

Argh! Posted on amdmb as well. Someone said it's the C.O.P protection but the CPU can't get so hot after 3 seconds. Besides I tested it on another board and it worked.

A7N8X Deluxe 2.00
Barton 2800+

Can't go into BIOS (cleared CMOS too), system shuts down after 3-5 seconds. Alpha HSF + Arctic Silver (re-applied 2x). I have re-seated the heatsink two times already. No go. All the fans are working, led is green.

Very frustrating :confused:

I had the same problem with an older ASUS board. The thing would shut down, then I had to wait for a minute or so to start it back up. It turned out to be the Power Supply. At the time I had bought a 450w (which was Athlon approved) PS which worked fine with my older MB but when I stuck the new board in I got the problem. I ended up sticking my old 250w PS back in (yes 250w :)), and it worked fine.

Are you using the CPU fan header on your motherboard? If so, are you sure your fan is plugged into the right one? I had this problem once where my system would shut down after a couple seconds and that was because the CPU fan was plugged into the wrong header on the motherboard. Stupid me. :angel2:

I don't believe it's a power supply at all. As to the fan headers, it's plugged to the PSU instead.

Although I re-seated the HSF two times I took it off again and noticed there is no paste imprint on it. Only very little part of HSF was actually touching the core. This is very weird, because I used my Alpha on a different CPU / mobo and never had that problem. Will try it again :p

[jAkUp]

are you using a cpu shim???

[volt]

Don't need one for Alpha HSF.

Working perfect now, the washers that came with Alpha were too tall and I couldn't screw it all the way in. Changed the washers to the little red ones voila!

26C idle! :eek:

Always, always, always use those red washers. :angel:

Anything else isn't worth the hairloss and high blood pressure. :p

[The Baron]

Whoa, you have to screw on the HSF?

Weird. I'm still using retention clips with my little goofy screwdriver which for whatever reason fits absolutely perfectly in every clip I've tried it with.

[volt]

Beeeh! Baron always likes to be different :p
I've had that HSF for about a year and it does a great job hehe.

[The Baron]

I don't like to be different, but I'm just special. Yay. ;)

[vampireuk]

I have a little goofy screwdriver for clips too! It has a odd pen like body and a pocket clip too. Booya!

kill me:(
:D

What are you memory timings? What did you set your RAM frequency to ?

[volt]

I dunno, I've had random reboots. Updated the bios, changed the timings and it works.

Are you running Norton AV 2003?

I am and my system has been experiancing intervals of unresponsiveness for a period 15-45 seconds, especially right after logging into WindowsXP and all the icons are loaded in my systray.

When this happens, I notice the harddrive light blinks briefly every second.

Hope it isn't that new WD 80GB I just bought...:(

Something tells me it's Norton AV 2K3 causing it, though.

Never had problems with Norton 2002. :confused:

I'm using NAV2K3 Pro w/ a WDSE 120gig with no probs so I don't think its the hdd, although I have a diff mobo. Also don't know if it makes any diff but I had nav installed prior to installing the nf2 drvs.
