Question about Biostar U8668 (U8668DV7) Motherboard

1 Answer

3 of 12 broken!

I was just trying to upgrade the system on my 12 u8668d 7.b based computers. 2 of them had virus problems and were not in use. I plugged in an extra hard drive and copied a full install using linux dd. One of the two not-in-use, and 2 others, now have the same problem: when I power on, they make click,click.... click,click.... sounds from near the power switch. Power light stays on, hard disk light flashes off in time with the clicks. They turn off only when I hold the power button. Same symptom with/without all peripherals including memory and hard disk, I have not tried without CPU. What is this and how do I fix it? I was careful, how has this happened to fully a quarter of the machines I've tried?

My pc is very slow. if i will open my pc sometimes it will hang it possible that i will reformat my pc?what OS should i install? can i install windows 7?

It's slow because it has been corrupted by a virus. So yes, you must reinstall it.
Yes, you can put Win7 on it, but if you're using the pc just for home use, no gaming , no special programs, it will be better to install a Linux on it - not only it's free but it's practically impossible to infect or hack.
Try this one

Getting late started and many virus

If your system will not boot up correctly and you suspect a virus is the problem, a recommended solution is to start your computer in safe mode and run a virus scan. By running your computer in safe mode, non-essential processes do not start and non-core components are disabled. In other words, only the minimum necessary programs will load. Tough to remove viruses, spyware and other malware usually have no chance to run and disrupt your system and can more easily be removed.
To run a virus scan in safe mode, you must have active anti virus software installed on your computer.
To run a virus scan in safe mode, follow these steps:
1.If your computer is on, shut it down
2.Power on your computer
3.Immediately after you power on your computer, repeatedly press the [F8] key (about once per second)
4.In the Windows Advanced Options Menu screen, use the arrows to select Safe Mode and presss [Enter]
5.Select your current operating system and press [Enter]
6.Select the user you would like to login under (if applicable)
7.When your system finishes booting, click the Start button on your task bar
8.Move your cursor over All Programs and navigate to your anti virus program
9.Click on your antiv virus program to run it and follow the anti virus program's normal steps to run a virus scan
10.After the virus scan is complete, Delete all detected viruses
11.Close out of your anti virus software
12.Restart your computer (it should start in normal mode)

I have an The Biostar U8668D - Version 7.1 Socket 478 microATX Motherboard. And my power supply stop working. I was wondering if i have to get the same one or i can use any kind of power supply.

Most modern power supplies will work they most all have a 24 pin connector for power which you only need 20 but you can still use the power supply either the last 4 connectors split off or you just let them hang off the upper side of connection( all explained in directions with most power supplies) you can mostly upgrade to a higher wattage power supply. so lets say you have a 300 watt one now. you can upgrade to a 500 watt one. just make sure it is of ATX standard.

Motherboard upgrade??

Dear kaname,

Your computer can support Windows XP, which has better hardware support and compatibility with the 2003 Office suit. XP also updates your hardware automatically once you are on the internet. You might want to try this.

Keep in mind that the older the Operating System, the harder it is for Office suites to compat. Newer Operating systems have better support for your computing. If you don't have HDD problems, the BIOS should not prevent you from loading SP2 for Win2000.


1. The SP2 Source Disk may have a problem
2. The Win 2000 you have already loaded may be missing components, preventing the SP2 to load.
2. Notton Antivirus versions and the 2003 office both reject Win 2000. They just don't like it; it's getting too old.

Get with it, Kaname!!!!
