I'm haveing this strange problem with several systems with the same spec's:

Asus P5GD1-pro
P4 540 3.2GHz
Kingston DDR400 512Mb 2x dual channel
XFX FX6600 128Mb videocard
160Gb s-ata 8Mb 7200rpm Maxtor
Floppydisk drive
16x DVDrom Samsung
16x DVD+-RQW Samsung
Enlight 4105 350w Case
MS Windows XP Home SP2

When playing same heavy game's like NFS Underground II the system hang.
After a reboot it says NTLDR is missing. I can fix that with no problem but
the hang issue stays. The system runs Prime95 with no problem. When I look
in logbook I see mass of disk-errors hdd0 and atapi errors.

Any suggestion?

Thanks

What voltage and current values are printed on the Enlight
power supply ? Maybe you have run out of +12V for all that
stuff ? Try to find a really good power supply, just to
use for testing.

If you are building systems professionally, you should get
a clamp-on DC ammeter. That is a tool you clamp around
groups of wires (like the four +5V wires on the 20 pin
ATX power cable), and take DC current measurements. You
can then run 3DMark in Demo Mode or Prime95, and take
measurements of the current being consumed from +3.3V,
+5V, +12V. Compare the measurements to the limits printed
on the power supply.

By doing that, you will have a good idea as to what
grade of power supply to buy, for the various classes
of motherboards you sell. A couple of meters (a cheap
multimeter, an expensive clamp-on ammeter) will help
take the guess work out of system builds.

A clamp-on ammeter can also measure AC current on the
input to the power supply, but my experience is, the
measurements are not too accurate when measuring idle
power (when the computer is sleeping in S3 suspend to
RAM), due to the current waveform being so distorted.
A power supply with active PFC has the best looking
waveform, as shown at the bottom of this page. The
active PFC current waveform looks pretty close to a
sine wave:
