Hi everyone new guy here... i have a k7vt2 asrock motherboard. running with 256mb ddr pc2100 at 266mhz. well i brought the ddr and placed it on the board, it booted up perfect no problems at all, ran through everything with no hicups.. until i put a usb in. as soon as that happend it shut down with no warning just black screen and start up screen. it wont boot up with usb in....and wont work if i put in usb plug in when windows is loaded up. so everyone heres a good puzzle for you to work out, thanks to all that reply, "tearing my hair out right now..wondering if the cure is a size 13 to the side of it,"

is the usb port physically built into the motherboard, connected via motherboard header, or a pci card usb expansion? what usb device are you trying to plug in? have you tried plugging in the same device in another system?

Welli suppose knowledge is power, i decided to spend a few hours reading of the net about everything i could on the motherboards and how it basicly works, the on board usb wasdraining the board of power when i pluged in any usb that needed power, the 256mb pc2100 ddr ram wasnt reciving enough power, so i removed my neons and one fan and it worked fine, thats just a temperoy solution. to also help the motherboard recive a steady rate of power a adjusted the jumper on the usb5.3v to usb5.3v(standby). so it only recives the voltage when its really needed, the long term solution is to buy a new psu (power supply unit), the 300watt i am only getting out of my pc is not enough, thats like putting a mini engine in a euro fighter jet, i forgot i nicked my brothers psu when mine went pop, so getting on the phone and ordering a new one, 500watt with fan control speed with see through casing and blue neon it matches the modded case i got, so happy days again... thanks to all that answered, and hope this information helps others.... thank you.. from maddy "it aint what you do...its the way you do it ?.......Large And Fast"
