ok i had windows xp on my computer but with a major problem. everytime i had any kind of usb attached before bootin my computer it wouldnt do anythin. i would log into my desktop and that was it. nothin would be there. not even the taskbar. therefore i had to make sure to unplug every usb(includin mouse n keyboard) before bootin my computer. if i did hat everything would work fine. so today i installed windows 7 hopin this problem would go away. it didnt. i still have the same problem except this time everythin freezes before loading windows. if i unplug the usb it immediatily loads.

happens with all usb's btw!

i have no clue what the issue could be..

Got a similar problem with mine at the moment - the rear USB ports are OK - But any of the internal ports that run the front devices, ( USB's & Card Reader) - if they are plugged in repeatable shutdowns or wont boot at all.

Its not the OS, as I tried from a bootable CD, same thing. New board arrived last week - just have to replace it.

Mines an ASUS - just over 3 years old (typical just out of warranty). :crying

Funny thing about motherboards. I used to be a big fan of Soltek. Two Soltek boards bought back around 2002 from the same supplier on the same day. SL-75FRN2 for what it's worth. One board died within 8 months and was replaced without question from PBTech in Hamilton. The other is still going and is two doors away from where I live.

Go into BIOS and check for an option "USB legacy devices" - it will either say it's enabled or disabled. Change it to the opposite setting and try again

What's your motherboard? it might be a buggy BIOS..

Did your USB ever work?

What's your PSU?

Agent 24 is correct. The machine is trying to run from the USB port. Good for sales of new boards, eh.
