I've bought a new pc. Here are the details:
Intel C2D 3Ghz (E8400),
Transcend 2 Gb 800 MHz ram,
nvidia 630i /GeForce 7100i mother board,
western digital 160 gb sata 2 hdd,
frontech 500W psu,
and i currently have 5 fans running (3 on cabinet, 1 on psu, 1 on cpu). When i check the exhaust air coming out of the fans outside, its not so hot.

my pc completely hangs even without any heavy applications running and i have to restart with the reset switch.
what the problem could be?
hangs occur with no mouse movement, even capslock/numlock lights not going on/off!
Also there's an 8 pin ATX 12 v slot in my motherboard but my psu gives only a 4 pin connector. i was advised to put the connector to the right side (the right half of the 8 pin slot) (the side closest to the processor). Is that creating any problem?
All my drivers are up to date and my system is virus free. I also clean my registry quite often.
I have internet through LAN and it's my observation that the hangs tend to occur if my internet connection is on.
I made the BIOS settings default but still it didn't help!
When i made the settings to "error-safe default", the system hanged while booting!
It's really frustrating! A problem with the hardware would be very very dissapointing especially since the pc in new!
Please help!
 
You could use a program like CoreTemp or something like that to monitor the CPU temps while you're running the apps that appear to crash your computer. You should try several different programs, as one program can give inaccurate reads and the E8xxx series have been known to have problems with the thermal diode...
