I have a list of the tests at: Hardware Diagnostics Try each one.
You can also use the Ultimate Boot CD - which has numerous different tests built into the disk.

oh I see them now, one more thing, could bent pins have something to do with it. if it is the cpu. and my motherboard doesnt support downclocking, is there a way I can lower the fsb.

I don't know if downclocking will even help in your situation.
Run the stress tests and let's see what the results are.

Do you have bent/broken pins? If so, I'd suggest posting to AMD Tech Support to see what they have to say. Although I favor Intel, I must say that I've received the best tech support from AMD over the last few months.

w00t!!! Driver Verifier to the rescue!!! (sound byte here: )
Looks like it blames MagicISO SCSI Host Controller driver (mcdbus.sys)
Since you've uninstalled MagicISO, I'd suggest watching for another BSOD (leave Driver Verifier working)

You can also remove BS_I2cIo.sys (it's still there). If you've already uninstalled that BIOS flash utility, then please post back for instructions on how to safely remove the driver.

Further info on BSOD error messages available at:

The following info is just FYI, I've already addressed the issues that I saw in the above paragraphs

I dont know anything about driver versifier, didn't even know it was running. how do I remove the BS_I2cIo.sys

Go to Start and type in "verifier" (without the quotes)
At the top of the search box, right click on verifier.exe and select "Run as administrator"

When the program opens, click on the button for "Delete existing settings"
Then click on the "Finish" button in the lower right corner of the window
Then reboot the system to reset the Driver Verifier to "OFF"
To remove the BS_I2cIo.sys driver please:
1 - Ensure that you can boot into Startup Repair from your installation DVD. If you can't, post back and we'll make other arrangements.
2 - Create a System Restore point (in case you can't get into Windows, you'll use the Startup Repair disk to access System Restore and restore the computer)
3 - Use Autoruns (which you downloaded for the jcgriff2 reports. Search for instances of BS_I2cIo.sys and disable them by removing the checkmark in the far left column of that entry
4 - Go to C:\Windows\System32\drivers and rename BS_I2cIo.sys to BS_I2cIo.BAD
5 - Reboot and see if the driver stays renamed (by checking in C:\Windows\System32\drivers
If the system doesn't boot to Windows, boot with the Startup Repair/Installation disk and get into the Startup Repair menu. Select System Restore and restore the system to the System Restore point that you made previously

I cant play any games at all -_- 5 minutes then they either crash or I get BSOD.


I need to know what exactly is causing this, because I was able to do anything fine for about a month.

I think you might find something different in the perfmon report.
