Problems with new system

[Mirko]

Hello
my system is the following:

300W PSU with 30A on 5V and 15A on 12V. I don't remember 3.3V...
Asus P4P800
2x256mb ddr400
Geforce fx5200
Sound blaster 128
hdd 20gb
hdd 6gb
cd-rom
cd-rw

Now, the problem is that when I'm playing a game, sometimes the game
automatically closes and return to desktop! I note this problem when I'm
playing Mafia but GTA Vice City and Fifa Football 2004 are stable.
Now I've installed 3d mark 2003 and during the first test, program closed!
I've launched it again and run the test successfully.
Voltages are OK, but I was thinking about 3.3Voltage, that is 3.15-3.18V.
What is the use of 3.3V in a computer?
I'm using high timings and DDRVoltage of 2.65V else the computer is more
unstable and "blu screens" appear.
In your opinion what is the problem?

Best regards

What CPU? Is it overclocked? What settings? What vcore? I've misplaced my
crystal ball.

crystal ball.

Yeah! Cpu! I've not written it in the previous post: Intel Pentium4 2.60GHz
not Overclocked with VCore set as [Auto]

Excuse me...
