~~~~-- Approx-- 2:30 AM july 10th, 2008--~~~~

The power supply i was using failed, it was knock-off brand.
I have determined the problem to have been faulty fan, it stopped spinning due to dust accumulation.

I am at fault.

However- i have tried to correct the problem by replacing the power supply with an ASUS 500w PSU. and multiple other PSU (i run a computer re-sale business from home. we mostly work with p4 dual core, or amd dual core. with budget 6200, 6600, video card.)

This motherboard seems to be partial to this specific (broken) power supply.

The problem is that when i run with over a specific ammount of amps (using a wall-mounted amp meter, ) the system freezes,

Somtimes sound will continue and video freezes.

Upon request i will provide any further information, i have a CAL tryout match tomorrow that i hope to make, please.. if you have any idea. help a felo =e= out.
 
What kind of video card are you running? It sounds like your new psu can't keep up with your systems demands. I ran into a similar problem trying to use my old psu when I SLI'd my 8800GT's, ended up getting a new bad boy Corsair 750W and have been stable ever since.
 
i would check the amps that your PSU puts out not the Watt's. then compare the Amps with what your hardware requires. This sounds to me like your PSU does not have enough amps. AMPS are far more important to have then WATTS. My computer is runing off a really old Power supply from a Dell 4700. It supports all this ITs only 450 WATT from what i remeber. But the amps on it are comparable with any 600-700 watt PSU out today.

If you can please write the components your pc is using. And the specifications of the PSU. Especially as said above the 12+ rail amps is what I'm most interested in, which is what feed power directly to your video card, just hope it's only need for more power and not a damaged motherboard or video card. :eek:

Dieinpeace, that's an awesome sig by the way.
 
amd fx 57, 939
2 gigs DDR2-1300 325 MHz 3.1 ns 650 MHz 1300 Million PC2-10400 10400 MB/s

(i know i know, sue me about it, oh.. and Nvidia fanboys.. Look up the radeon 4870, less than half the price of Nvidia's flagship and its within 10~% of the performance.. BEAT THAT!)

anyway.. im running a Radeon x1300XGE (extreme gaming edition, HA, yea right.)
Sound Blaster Audigy 2 zs platinum.

1x eide maxtor 150 gig 10000 rpm drive, 1x SATA Seagate 150gig

um... 6 case fans (2 in front, 1 in front of hdd's 2 in read, 1 in side window)

and a light up bunny thing that hops around in the bottom of the case..lol.....

anyway i was using a 500watt antec before, and it worked fine.

but i've noticed while trying to upgrade the power supply in the past (even when everything was running perfectly) this motherboard (or video card) seems to be partial to that specific PSU for whatever reason.

after some experimentation, i have determined the problem to be the video card, its either broken, or it pushes my PSU over the limit.
i have no way of determining the amps, i know that I=V/R, so if i find the resistance i'll be in good shape

anyway.. here are some voltages that my system seems to be spitting out, according to speed fan

VCOREA: 1.47
VCOREB: 1.65
+3.3v: 3.31
+5v: 5.19
+12v: 11.07 (thats a bit low.....)
-12v: 0.72 (thats odd... and extremely high if im thinking correctly)
-5v: 2.19 (also very high.)
+5vsb: 5.40
Vbat: 0.10

maybe that answers a few questions? i dont know..
the system works fine with a crappy PCI geforce 2. but i get 25fps in 640x480 low detail, and thats hardly gaming.
thanks for the help
 
speedfan may not be giving you the correct voltage readings...there are quite a few known bugs with speedfan and different hardware/software configurations. if you're that worried about the specific voltages that your PSU is putting out, get a good multi-meter and check them manually. just be very careful :-)
 
ok after a little research i saw that people are recommending 18 amps on the 12 volt rail for a Mid-range video card.

the one i have now is 8amps on the 12 volt rail (no where near sufficient), i've also tried running the ATX power supply in my computer with an alternate 200watt SOLELY for the video card, and to no avail. As we speak im using the x1300xge for browsing, and as soon as i turn on a game its going to lock up.

So. i need to pull 10 amps out of my arse.... hmmm... i've got 50~~ broken/used/old power supplies around, im sure i can peice it together, i've got a trusty soldering iron and rosin flux core solder... ready to go... im also good with soldering.

EDIT--
the SpeedFan voltages are correct according to my bios, except for the fact that my bios doesnt display negative rails, like -12v, or -5v

so... any idea what i could do to fix the problem without buying anything?

wow...you're going to build your own power supply? dude - i want to see a picture when you're done. PLEASE don't fry yourself <grin>
 
i got it working


i had a 450 watt psu, and i replaced a few bulging capacitors .

but that wasnt the only problem


it seems that the NF3 (nvidia Nforce 3) chipset has issues with x1300 X1600 X1900 series radeon cards,

i originally tried the repaired PSU with the video card and no luck, but after setting the AGP voltage to 'HIGH' and the AGP setting to 4x instead of 8x, it works perfectly.


I know, AGP wasnt originally intended for these cards, but i have more than a few computers, and this is the one i like to use for CS:S.

it works fine, --- 150~~~ FPS, and everything is smooth,. so its no big deal.



im just glad i got it to work, and i hope maybe if someone decides to use the NF3 chipset with a radeon x1000~~ series card--- they notice this post, because this seems to be a common problem.
