It certainly SEEMS to occur often when I am watching video, but watching video does not always produce the problem. I initially caught this pattern of it happening when watching video becuase I used to watch the video on my computer while the video resided on my sisters computer and the connection break caused the video to stop. But I have never been able to reproduce the effect intentionally so I just assumed I saw something that was not there.

However, it does happen just as often when idle ... ie when I am just surfing the web.

512 RAM.

I'll do some memory intensive processing to check this idea out.

thanks for the tip

Hmmm alright with that in mind would you be able to post a Hijackthis log onto the forums so we can check to make sure that your system does not have any "Spyware" that could be causing this.

You can find the Hijackthis program in my signature under "Handy Tools"

HJT post split and moved to HJT logs section.

Finally, possible signs of getting somewhere. :knowing:

Possible overheating LAN components?

So I am trying a whole bunch of things to get a raid card to work and I needed to use the computer for a couple of hours so I leave the side cover off the case. I figured no side panel, cooling is not a problem I turn all fans in my computer down to lowest setting ... to cut long story short something seems to be overheating.

ANYWAY I have finally found a pattern for the occurance.
fans at lowest setting, speedfan registers CPU as 35-40 deg Celsius, wait 5-10 minutes I start getting "disconnection" flashes regularly ... one every couple of seconds.

I turn fans up, speedfan registers CPU at 30 and below degrees celsius, wait 2-3minutes the flashes stop.

Now I keep doing this [probably excess of 10 times] and its a constant pattern.

So one last thing I try is turn all fans down, run spyware doctor [it uses a fair bit of the cpu], speed fan registers CPU at 40+ degrees celsius, and sure enough the flashes start sooner AND it gets to the point where I get totally disconnected from the LAN and can't reconnect.

So my PRESUMPTION is something is overheating, not the CPU obviously, and I was monitoring RAM usage the whole time and it never went below 150MB free.

The problem is
the chip with the marvell logo on it, I am assuming is the onboard LAN chip, is not noticably hotter to touch.
I am not actually using the LAN connection when this happens ie the network utilisation is 0%.
I've read that computer case ambient tempreture gets to 40+ degCel, I would estimate at the moment its 25 degCel ambient at the hottest
Ive googled it a bit and no one else seems to have picked this problem up as overheating.

Any ideas are appreciated.

I've been a bit busy looking for jobs and trying to fix things so I have not been here for a while.

But I think I have solved this problem. It appears to be a overheating south bridge. I did some reading and it appears the southbridge takes care of the onboard sound/pci slots and the like. I bought a northbridge cooler and "stuck" it on to the southbridge with arctic silver and I seem to have got rid of this problem at the moment ... i hope ... but it still does not make any sense to me.

Nice Job Eric,

Keep us up to date on this issure if it comes back. But it sounds like you found the problem. I know it can be frustrating not to completely understand the roots of a problem. But I find it amazing that these things work at all. :lol:

See you in the forums.
