Henrythewound - MB Killah

I bought a ASUS A8N5X Socket 939 NVIDIA nForce4 ATX AMD Motherboard from NE last April. It lasted about 3 months before it completely died, no signal being sent to monitor, cant open cd tray etc. My buddy and I swapped out every other component in my case into one of his computers to determine that it HAD to be a bad MB. NE sent me a new one, it lasted 6 months before doing the same thing. NE thankfully accepted my return a 2nd time and sent me back a repair (minus all the cables and CDs I sent them with my faulty board). It worked for 48 hours. Now I am sending it back a 3rd time, NE will not send me a diff board but will send a same model replacement.

I cant think of anything I might be doing that would cause 3 boards to fail. I am running a simple setup, 1 HD, 1 gig of RAM, Windowx XP Pro, no modding or overclocking of any kind. The only thing I could possibly fathom is a electrical timer I have plugged in across the room. Every morning it turns on a light from a different outlet. There is a small popping noise that can be heard from my compuiter speakers when this happens. Of course this also happens when I turn anything on/off in the room. I thought that maybe the repeated power on/off could wear away at a component of the board I am using a basic power strip to plug my computer in, I am thinking of springing for a better one.

CLIFFS
1) same model MB dies 3x over the course of 9 months
2) possible spike from other electronics in the room turning on/off to blame?


Any thoughts or questions welcomed.

Thx, Henry

Hmmm, its just the one that came with the case I bought from Newegg. Their site says it is a 350watts PS2 ATX12V.

Hmm...it seems to me you just answered your own question.

Just in case you don't get what i'm saying: You almost certainly killed your own motherboard three times.
Crappy PSUs can kill everything they are hooked up to.

Also, while i doubt this is an issue, get a battery backup/better surge bar for your PC.
 
How would a cheap PSU kill the MB? In other words, what would a "non-crappy" PSU do/ not do? I dont have a problem buying a better power supply I would just like to know for sure whether that is the issue.

 

To answer your question, generally a cheap *or defective* PSUs have poor power regulation. It has to put out 12V, 5V, -5V, etc within a tolerance. Maybe the 12V line overvolts to say 13-14 volts regularly. Maybe it dips to 10V under load. Mobo vendors on the other hand design to a spec, of course allowing a certian amount of fluctuation. If a supply goes outside that range, it could damage the board. Could be in a second, could be in a month. Depends on how *out* the lines are, and the filtering on the mobo, and a slew of other things I am sure.


 
Yreka, thanks for your answer. I am looking into better PS units on newegg. My friend recommended Antec. Looks like the lower price for this rand is around $45, but I suppose it will be worth it if it does not keep frying the MB.

PS- nice sig

I was looking at this one as well, but reviews of antec and FSP branded power supply nits seem to be the best. Time to bite the bullet and spend a bit more in the name of prevention.

Thx,
