About 2 months ago my PSU died so I bought another and replaced it.

Since then i get a problem which is getting more and more frequent.

Everytime I'm playing DC all of a sudden the PC crashes and switches off completly. At the same time a two tone siren type thing farts out of the back and will not stop until I pull the power lead.

This only ever happens when I'm playing DC so I presume something is over heating when it's being worked hard??

How can I be expected to pwn all you muthas when i have to keep booting up again?

Any help greatfully received.

JJ

CPU overheating?

seems like the simple explanation yes but why? Could it be that I have not bought one with high enough wattage?

The beeps should tell you what the problem might be eg: http://www.amptron.com/html/bios.beepcodes.html

Not too sure if this is any help but I believe some pc's have a number display [on the mother board I believe] that gives you a number which you then look up to find out what is wrong.

I stil say temp, you shoudl be able to find a temp. monitor program easily

Ok that PSU should be more than powerfull enough to run your system. Although I have never heard of that manufacturer.

People should never skimp on psu costs. thats the thing that makes all your expensive h/w work, so if that doesnt work properly, you h/w wont work properly.

Ok so it could be a few things

1) CPU overheating (unlikely as you werent having problems b4)
2) Graphics card fan has stopped working, and that is overheating causeing the pc to shut down.
3) The PSU cannot sustain the right amount of power needed all the time. Do you have all of the HDD's/graphics etc running off the same wire from the psu? if so swap them round a bit.

Run some stress tests on your pc from windows. Tools for this you need are

http://www.almico.com/speedfan (monitor fan speeds, temps etc)
http://www.panopsys.com/Downloads.html (allows you to see if your cpu is throttling (downclocking when under stress))
http://users.bigpond.net.au/cpuburn/dow ... urn-in.zip (tool for loading ur processor up 100%, for anyone else reading this this will only work on single core systems)

Let us know what happens when you run these (run them at the same time)

Hope it helps

Ok thanks FF, I wil try all of those this morning. I had just downloaded a Sensors view monitoring programme and the CPU is running at 80 degrees What should it be at during normal conditions?

More worryingly and possibly the cause of the problem is that it says the main system fan is at 0 RPM but they all seem to be working.

80 degrees is usually when the PC will reboot to stop the melting, I think you can set it higher in bios, but I wouldn't.
I would get some Arctic silver thermal paste for your cpu fan, it took 10 degrees off my temp,
or get a bigger cpu fan which will probably come with arctic silver.
I use this one and mine doesn't get over 50 degrees (currently at 31)

holly shite, thats smokin man, lol.

That is serisouly wya to hot, need to sort that ASAP or you could damage your chip. Thats why the system is shutting down, the chip gets to hot and an emergancy command kicks in which kills the power.

Its wierd how you never had that problem before. Are you sure the fan on the PSU is spinning? or for that matter the cpu fan? (have you taken the case apart?)

dont worry bout the system fan, it might not be connected to the motherboard, so it cant monitor it.

Thanks all for your help. It needed something basic - it's called cleaning!

Once I got it downstairs into the daylight in order to clean all the fans etc. I could clearly see the CPU fan was clogged with dust. Cleaned it all out and now running at 50 degrees.

A lesson learned.
