Onboard USB 2.0 hard locks system.Reverting to 1.1 mode solves it

Hello, thank you for taking the time to assist me. I am a very experienced computer user and built a custom rig based around the AsRock 775Dual-VSTA motherboard, which features on-board USB 2.0 ports. Whenever I try to transfer data from or to a device (such as an external Hard Drive, MP3 player, digital camera...), the system will freeze within a few seconds to a minuet. This is a brutal hard lock, the mouse pointer will not move, nothing responds and even the NumLock light stays lit no matter what. Data corruption can result wherever a file was trying to be stored (cause only part of the file gets over). A hard reboot is the only recourse. I have also noticed that intensive software such as games will be unstable and crash every 10mins to an hour or two, even if no USB device is connected save my mouse and keyboard.
The really interesting thing is, when I disable the 2.0 support and rely on legacy 1.1 mode, all problems are solved completely. In fact, my system has never freezes or crashes when 1.1 mode is in effect. SO, why is my system doing this? Faulty hardware? Bad configuration? I have the correct drivers from the manufacture's website and have tried drivers directly from VIA (this board has a VIA chip set). Nothing seems to work. Could there be a Windows service interfering with this? I am grasping at straws here and no, I do not want to just go and buy a cheap USB PCI card, I want what I paid for already to work properly. Thank you again!

    Well, my BIOS is already up to date (v3.10). When 1.1 mode is enabled instead of 2.0, no problems occur, so I doubt other hardware in my system is a problem. Thank you for the suggestion none the less!

Hi, I have a Nokia 5800 (S60V5), I have being experiencing the following, 1. When the phone is in standby mode, 2. There is "no network" or sometimes "sim registration failed" 2....

Hi sir, 1) It asks the pin code since you or others set it in the settings-> security setting->PIN code request. If its ON state, You have to change to off mode. That time it will ask you the pin code. If you don't know the pin try with 1234 or 12345. Remember don't try more than tree times. It will get locked.Or Call the service provider for of your SIM from other mobile and get the PIN code from them.
2)If its restarting again then the problem is with the mobile OS(software). It can be solved only after changing the OS. For that you have to go to a Mobile Service Shop.

I dropped it after it was hooked up to another computer with a different operating system now whenever i plug it in to a computer it is displayed on the computer screen as removable disk not a hard drive....

This is quite normal in my opinion, most USB drives are installed as removable devices, because they can be removed anytime from the system, right?
The difference is that for removable devices the system optimizes writing for quick removal, for example turns off write cache to write immediately to disk, and also shows an option to "eject" the drive, which in this case means "let go of the drive", checking that no files are open on it.

My PC does only has 1 user account and ther is no

You can always remove the hard drive from the system and put it in another computer to retrieve the files. Something must have corrupted your user account settings. I've noticed some systems when they were installed that people never paid any attention to the login screen during installation but you might try logging in as Admin or admin with no password. This works once in a while. If when you put the hard drive in another system it won't let you open the "Documents and Settings" directory (if it's XP) because you're not logged in as that user, you'll have to put it in a system with Windows Vista. Vista will allow you to take control of the directory and let you access this part of the drive.

You have experienced a system emergency shutdown. In otherwords, your computer crashed. You can:
1: reinstall your operating system.
2: use a OS recovery disk to reboot the system.
3: send the computer to a data recovery specialist.
4: return the computer if the warranty is still valid.

Good Luck!
