And of course it all sounds painfully familiar. :( Sorry about that! The good news -- well, for me -- is I can learn from your painful experiences. It's unlikely is a problem with a loose wire. broken trace, intermittent contact, etc. Good news is those might have been fixed with solder or electrical tape or replacing a relatively inexpensive part; bad news is the fix is replacement by a relatively expensve pair of parts. > And as it seems one cannot bypass the Southbridge that means one needs > to replace the motherboard.

Friend likes Gigabyte for reliability KM> (I've never owned one, just haven't come my way), and they hawk I've got/had an old MSI. Not sure about about the feature set as I tend to set and forget. Do have a Gigabyte around here some place... it's snoozing currently -- nmap is seeing it but Angry IP Scanner isn't identifying it. KM> Then of course I wind up with a pile of Asus, cuz that's what KM> falls on my head. I've learned to use more shelves so less stacking. KM> Stay away from Biostar. Had something from them a long time ago. KM> No-name boards are mostly Chinese manufacture from recycled Some parts I will go with 'random Chinese stuff' as most tend to be made over there anyway but for motherboards, video cards, power supplies, etc., I will save up my money and pay the extra cost for the name brand. of course again there is the difference between me as individual and you as (at times) contracting to a business. KM> (NO freakin' RBG blinkenlights would be a plus...) Unless they provided some sort of a warning when the fan failed, componets getting too hot, etc. Did see a case some time back with an essentially medium-resolution monitor on one side. To me that would be handy for something like my weather station project: take a glance once in a while to see it's 49ø out. the wind's from the south at 10 MPH..... KM> CPU will be constrained by chipset, but the 9th generation Intels KM> have come down some in price as the next generation come out, KM> so... Buy the new 2020 models at used prices! ¯ BarryMartin3@ ® ¯ @MyMetronet.NET ® ....
