I am more than a little upset with my brand spanking new ASUS A7V8X-X based system with AMD XP3000, nvidia GeForce FX5200, 1GB ram, Tower case (AKA barndancing), coolmaster fan fitted, decent 400W PSU with integral in/out fan. Anyway - it will not apparently stay up in anything near a stable way - nothing like my old AMD XP1900+ which is really stable but was a Packard Bell prebuilt low profile baby system. The symptoms are simply and reandomly that system does a restart at any point (and I do mean ANY). This is why I do not think it is temperature related. I have even had it occur that the system restarts and the first thing it does (after I typed my password) is ANOTHER restart!! Running XP Pro it does create a dump and I do get to send this to MS support, the blue dump screen and diagnostics from the dump analysis tell me to suspect drivers or BIOS possibly - yet so far as I know these are as supplied by my system maker, I have yet to add all the other goodies I got to go in there (nor will I until this is fixed!). Any ideas/comments/suggestions appreciated... I'll be pursuing my own investigations and as I say expect to hear from supplier too. Would I get the symptoms I describe if this is temperature related? I am not o/c'ing and supplier should give cooling adequate to the case they build in - surely? Typically seems to run the the high forties, which I know is hot but is it tolerated by board/processor? I have looked on the AMD site and destructive temps are actually a lot higher (over 70oC!) so far as I see - also believe my supplier used a superior fan than some (although no extra case fans - case is big and roomy though!)... as I say I have the temp monitored and am hopeful that's not it because if I start adding fans the machine's going to get noisier!
