Switching off!

[Evilkitten]

As you might know I just set up a desktop computer for myself and working very well.

Just it keeps switching off at random points especially during times it needs more such as video games.

What I got at the moment is...

Motherboard:-ASUS P5N-T Deluxe AiLifestyle Series nForce 780i SLI Socket 775 8 channel audio ATX
CPU:- Intel C2D e8400 @ 3.0ghz
Graphics: - GeForce 8800 GT
Ram: - OCZ 4GB PC2-8500 Platinum (2x2GB)
HDD: - Seagate barracuda 500gb sata2 16mb
CD Drive: - Samsung SH-S223F 22X DVDRW/RAM/DL Serial ATA Black Bare Drive
Computer Case: - XION II Black (Blue LED) Steel Mid Tower Gaming Case ( 2 x 120mm and 1x80mm fan)
Power Supply:- OCZ 600W GameXStream SLI Ready PSU

Do I have the wrong amount of psu or could it be something else?

I believe I have everything connected right and have rechecked many times...HELP O.O

Take a peek at system log if there's anything that could indicate your problem.

Check CPU heatsink (and fan) so that it's properly fitted and won't twist itself off from CPU.

yup sounds like a heat problem - cpu heatsink is first culprit for this can you monitor the system tempratures and see which is triggering the shutdown?

if its when your GC kicks in you may be getting heat build up from the GPU and could need another fan to help with airflow.

Make sure airflow is not just circulating hot air but is actually being pushed out somewhere and the outlet is not covered or too close to wall, table leg or other obstical.

Here's lga 775 installation instructions.

The normal diasgnostic path for this problem is to first check the running temperatures are correct in the BIOS, however if no audible alarm is sounding at shutdown then it's least likey,

you will need to open the case and check that the power
on switch is connected correctly on the motherboard side, consult the motherboard
manual and re-examine the pin out on the switch / led block,

then bypass the case's power switch, by shorting the pins and powering up the unit
and letting it run, if it returns to normal, then you might have a damaged case switch,
they are very fragile and just fitting them in case can break them internally

if the unit continues to shutdown despite this, get hold of another PSU and try running the
system again,

after eliminating the above, it's time to look at the motherboard, it needs to be removed
to see of any contact is being made with it's underside, and the fixing plate in the case,

remove the cmos battery for several minutes, then put it back in again, re enter BIOS and restore your optimal settings,

if the fault persists you should contact the motherboard maker for RMA.

Anything new kitten or did your compter let out the smoke it operates on?

Played around with the fans and added another one, pulled away from the wall and appears to be working properly and hasn't shutted down yet. Now I can finally played oblivion again =D

Now to sort out getting it online to play Spore O.O
