"At this point" of you doing absolutely everything except offering a recoded solution to your lousy USB voltage thresholds you mean. Further you would suggest I only use the board's stock ports.. always have until this week. I've removed all extensions, I have no hubs, the problem continued until it stopped entirely, mysteriously, and has remained absolutely silent for one week, following my reversion to a previous OS image with slightly older drivers that will absolutely be as big a problem at some totally random time in the future as they always were at some totally random time in the past. To which you advise: that I take your last board made that, fully supports Windows XP, and you cannot deny this board physically absolutely, fully supports Windows XP, was designed and built a decade beyond XP's inception specifically as an XP board, and update it to a newer OS for which its architecture is totally inadequate to run properly, because you've after the time of sale decide that you don't want to write software that supports it anymore, because it is a discontinued and probably short sighted piece of hardware that did not perform as economically well as it was thought it would.
The proper response you should have given me would have been tough s*** sucker.
So, you've ripped me off. Let's be clear about this one fact. You've sold me hardware for which you are willing to say it supports XP but not physically willing to support it with proper software, to which I might say... YET AGAIN. Because the fact is you did this same thing with my Windows XP running HD4000, all fully supported mind you, with words, just not software. To which I had to spend another $150 dollars on a new video card that shocker among shockers completely supports windows XP even here at the cusp of 2014 nVidia is still writing for XP, like any good company that stands by what it says it does.
You owe me a refund, you've sold me an $90 dollar board that does not behave well, and a $150 chip with HD4crap that would not stop crashing when confronted with anything complex that ultimately cost me more than the whole chip to bypass. Perhaps you've something better suited to my absolutely XP needs, to exchange with, because as for my "local support center" I'm look at them right now. I bought this from amazon and newegg over one year ago and there are no warranties left for this long headache. Only my dwindling opinion of you. Leave me hanging and that will last forever despite my bulletproof P4 idling quietly through its 11th year, you've changed Intel. Any wonder you've lost such market share? You're not going to make it up by shorting me, I professionally write exposes about malfeasant companies.
Be better, support what you say you would or flat out give me my money back now, and I'll never trouble you again. Fail me, and our troubles have only just begun.
