I have a PC which I built myself using pretty high specs, however, in my naievity i decided to not spend as much as i should have done on a PSU and got a very generic one. The system works fine, and i have no issue apart from this, but i want to check whether it is almost certainly related to my bad choice in PSU which will get upgraded anyway, but I just want to know! : Basically, my system will crash out completely if i leave USB 2.0 enabled, if I select USB 1.0 instead, the system is probably the most stable system I have ever used! I also find that if i plug USB peripherals into different USB slots (hotswapping), then the drivers reinstall unless it's plugged back into the same USB slot... isn't this unusual behaviour, i'm pretty sure this never happens on any other system i've used? Surely the driver works across all USB ports and doesn't require a reinstall??? Basically I want to know if the PSU could be affecting the first problem that I mentioned - does USB have a significant power draw increase which may account for the system crashing out by instable power line levels?
