PC shuts down after 10 mins

[mickc]

Have just finished putting together a new PC, After running for about 10 mins it shuts down and takes another 10-15 mins before I can restart it.

Bits I've used
X Blade Midi Tower - 450watt PSU
ASUS M2NPV-VM motherboard
Nvidia GeForce 7300GS 256MB graphics card
AMD Athlon 64 x 2 Dual core 500 Processor
160GB HDD (SATA)
Xilence Icebreaker 64 Pro HEAT (CPU Fan)
Liteon DVD rewriter (SATA)
Kingston 1GB PC2-5300 CL5 (mem)

I would have hoped the PSU would be able to support this setup.

Any help would be appreciated

Sounds like it might be temperatures, when you fitted the heatsink had it got thermeal paste pre applied or did you apply it yourself?

I would check the temps and see what its getting tup to.

Personally im not a fan of psu's bundled with cases but i would have thought is should be ok to run youe setup.

Watch the CPU temperature in BIOS - see if it keeps on climbing... If so - check the base of the heatsink to see if there's a little plastic cover on the thermal compound - it's easily missed and acts as an insulator so the heat can't get to the heat sink.

Thanks for the replies
Initially I used the Fan supplied with the CPU (already had Paste on it) and the PC shutdown (checked the CPU temp via BIOS it went up to 44degrees C stayed like that for a couple of mins then shutdown (motherboard temp was 35 degrees C
I then installed the new CPU Fan (Xilence Icebreaker) andapplied paste that came with it restarted PC straight into the BIOS, monitored CPU and Motherboard temp
Again went up to 44 degrees C (motherboard temp was 35 degrees C)
sat there for a couple of mins then shut off

Would this temp be to hot? I could'nt see any settings in the bios to indicate a overheat temp shutdown option.

Thanks again for replying so quickly

44c should be well within the shutdown temperature, could be the psu but i would be suprised if it was (you never can tell with these generic bundled jobs though), can you check the voltages, either within the bios or some utility within windows. If any of them seem low (+/-10% is the spec i believe) then it maybe the psu over heating, might get a rough idea by the temperature of the air being blown out the back of the psu too.

Thanks for all the replies
I have resolved the problem by inserting the CPU fan power cable (3pin) into the POWER FAN connector on the motherboard rather than the CPU fan connector. The fan now runs at aprox 2500 rpm (recommended) rather than 1500. The CPU temp seems to be stable between 33 and 39 degrees C and all is well.

Thanks again for pointing me in the right direction.

CPU fan connector was probably running at a lower speed due to the motherboard lowering the voltage, again this is normal and as the loadon the cpu rises causing the temps to rise also then the mobo would, normally, increase the fan speed.

But if what you have done has sorted it out then thats all good too :D
