C'n'Q Problem  

I've had errors while expanding files and i've normally had to re-burn the DVD at the slowest speed to reduce errors. This has helped in other cases too.

It's just a thought

Hi Dwarf,

Yes I have CNQ on my system too :), I don't use it but have not had any issues running with Vista or 7 with it enabled.

The fact that the issue started with the CPU upgrade would lead me to check for a Bios Upgrade to ensure latest compatibility.

Why the issue does not happen with XP is strange and appears to rule out a fault with the chip or MB

It has worked with my first install of Vista. After a few months i get problems with my CPU and I'Ve changed it. After that it worked a few weeks but then I got this problems.

Hi Andre,

What sort of problems did you get?

Hi Andre,

Sorry for not replying sooner. You said that you had replaced your CPU - what was it originally?

Hi Andre,

Unless there is some sort of inherent fault with the motherboard (which is unlikely, since you have replaced it), I think that we need to look elsewhere. We can virtually ignore the components that you have replaced, and instead look at those which you haven't. Of these, the chief suspect is the PSU. The fact that you experience problems when CNQ is enabled but not when it is disabled leads me to suspect that there is something wrong with the PSUs 12V circuitry/regulation. This supplies power to the CPU (via the on-board regulators), but it also supplies power to the motors in the system, amongst these being the HDDs. If you feel confident enough, and have access to a digital multimeter, then you can check the voltages yourself (I am assuming that the power connector to the HDD is the older Molex type rather than the newer SATA power connector). Switch the meter to DC voltage input, 20V range (if not automatic), and probe the yellow and one of the black wires in the connector. Make a note of the readings. Try this with CNQ enabled and disabled.
