Uploads fail with no error message

i'm old programmer, new world of arduino.  received vilros ultimate starter kit uno board christmas. 

i went arduino.cc , downloaded windows installer , installed including drivers.

i started ide , plugged in uno - no circuitry attached.  opened blink sketch should make led on pin 13 blink.

i compiled , have included verbose output below.  looked , quick (10 seconds?). 

i checked/set board type , serial port in ide.  set vebosity max , both compile , upload.

the tx led blinking , led on pin 13 on solid.

i started upload ide.  verbose output included below.  upload went through last line in 5 seconds.  tx led goes on solid talking uno.
nothing happens 5 minutes , last line comes saying upload failed - no indication why.

the uno remains tx , pin 13 leds on solid.  hitting reset button on uno causes pin 13 led flash few times , come solid.  tx led remains solid through reset process.

the way uno original state removing usb computer , replacing after few seconds.

i first loaded , ran ide on laptop same results.  moved desktop, giving output included below - no difference laptop.  have tried using different usb connections on both laptop , desktop - no avial.

i've gone through trobleshooting guide, found nothing helped.

i'm worried have bad uno board.

any hints on should do?

thanks
