So, maybe start eliminating all possible influences one by one: What's exactly your computer, type, processor, internal memory, windows, power supply strong enough, how many USB devices use just one USB controller at the same time? (f,i, make a screendump Belarc advisor, or post a saved HTML file). And what software is running at the same time, see taskmanager?. Alas one cant make a screendump from a MOBO BIOS, but a phone might do the job. PS ever updated it's BIOS? Maybe the power supply sucks, happens often when it gets older; voltages can by vary-ing, ... ever cleaned out dust? Monitored hardware temperatures, there are tools for that showing sensor output? Sometimes a cooler sucks and things get locally too hot, like processor, memory .... F
