pc just shuts down

[jdenm8]

It is not a brand name computer. It was, quoting myself from times long gone: "bought from the computer shop down the road."

It is currently running in an old model ('04) Tsunomi case and instead of having the air intake grate on the front of the computer, It has it on the side with a reversed funnel thing, directly above the CPU, emininating a fan and using the vacumn created by the CPU fan to ventilate the case.

The computer is running in an un-airconditioned room that, during summer, frequently hits nearly 35*C and once hit 45*C. Also, the air intake is in a rather dumb place as the computer seems to keep creeping back over to the wall on the left, blocking off the inlet. I didn't think computers had creeping little legs.

The computer does have an exhaust grate on the back of the computer with no fan, but hot air is getting out of there in droves.


I will see if my father did put any thermal paste on the processor and if not, I will run down to Jaycar, Dick Smith or similar and get a syringe for (quickly flicks through Jaycar 2008 catalogue), bugger the prioce, I can't find it.

You'll find that the latest Graphics cards will need at least 400-450w, which will be stated on the box, and everything else in the PC that's connected to the PSU will need their share too.
HTH,
Smiley.

My power supply is 350w. I recently changed my graphics card to an ATI Radeon x1050 with 256Mb. Since then I've been getting random reboots during startup, with Windows message "Your computer has recovered from a serious error". I can't find any driver issues that would cause this, so do you think I should upgrade to a 450w PSU? I don't know the power requirements of the X1050.
Thanks,
Mick Berg.

If youv'e read though this thread you would of seen that I was told to get a higher one for my mate as the psu will only use what it needs,

I'm running a 8500GT 2 hard drives 2 dvd rw drivers 4gig ram and lots more I'm runing a 750W psu which is only a few months old but I'm looking at getting 1000w (thats the top at the moment) as I want to run 2 8800gtx.

Your 750w PSU should be able to cope with 2 x 8800 GTX's in SLI mode. That's providing you stick with your existing 2x2x2 (HDD's, DVD's & 2 case fans).
If you are going to be putting in anymore HDD's, etc, (plus SLI), then I'd go to the 1000w.
Footnote; With low wattage PSU's, it is not only a watt's problem you need to worry about. You need to also make sure there is a dedicated 30A on the 12V rail, (that's used by the video card).
If you are going to invest in a new power supply, then make user it's over 28 amps, preferably 30 amps for the 8800 cards. With the 8800 & 8800 plus card's overall wattage is important, but amperage is also very important...

Lads its not all about who has the biggest PSU,
my little fella (computer) has the 9800gt x 2, 6 500g sata drives and a core2 8400 and a mobo to match the bits theres a tuner card a extra pair of LAN cards and 4gig of 1033 Memory (expensive exhuberance thar was)
and guese what 450watt dinosour psu guesing its drawing around 420- 440 watts at full power and the only reason why i have problems (occassionally ) is caused by Vista and the nvidia driver texture features, i repair computers (proffessionally) thats why i have so much digital realestate for those thinking what the......
Brands - not price still do matter in the parts business and also where your retailer sources his stock for warranty purposes the other reason to buy or not. A Good qual psu 450w is an outstanding source of energy for any home pc even sli'ed and some good go in them. There are "rated 450watts that really don't come close and the True 450's that are 450watt.
recomendations - icemax ,smartpower, Enlight and Antec 550watt, less than $50will work, but it all depends there's so many models and parts and combinations and it is all up to the beast within and only really go higher if you switch to 64 bit hardware and go above 4000mb ram and spend enough on a pc to get a small country out of debt.
Just my thoughts any way. i think even i learned a thing about a case change sorting the problem at the beginning of this thread.
Happy computing - shane steere

RETRACTION..... i thought about it and did my sums minumum 600w with those brands ensuring tasked pci power connections...sorry

Meatloaf747 is spot on
