Damn well better be an issue with the graphics card, if its not faulty then I have a huge issue, because I don't know what else it is, power supply or mobo, surely if power supply isnt enough, it will work for a bit, then demanding tasks it will stop. (Considering I'm 30 watts under the recommended, and thats like full load).

RIP Ghostie's computer machine~

My secondary display has been acting up the past few days now. Doesn't display anything but a white screen now and needs to be turned on and off a few times

get on aim

It's worth remembering that the 12v rail needs to supply enough current to power the system, and if the amperage rating is too low, it doesn't matter if the PSU has a high enough wattage rating. This GTS 250 of mine recommended a 450W power supply that could supply 25 amps on the 12v rail, and my 550W (more than enough wattage, right?) only rated its 12v rail at 18A. That's why I overcompensated and bought a 700W PSU so that I never run into that sort of problem again. I think your 600W OCZ should have two 25A 12v rails, so it shouldn't be a problem?

[Limited]

So, say they test the graphics card and it works fine, what should I do next? I'll probably ring up tech support and see what they can do, then again, thats same people that told me PSU is adequate for it.

Buy a 700W PSU? Noting, I'd have to send the 600W back, again more delivery charges =\

Varmint, I gotta be honest I dont know any thing about PSU's, I have no idea how to tell :P Heres the webpage for the current PSU I got.

Well, on the CPU there are two tiny dents in the metal where the lever thingy comes down to hold it tightly in place. I've re-seated it twice now, and I'm pretty sure it's in there correctly (lol). On my last two computers I've never taken the CPU out so I don't know if this is normal or not. I think the RAM is okay, because any number of sticks in any configuration of slots doesn't seem to help.

I think the power supply is okay (and it is high quality), because things seem to be happening on the motherboard, it just gets stuck at random postcodes (4F, 3B, 51, etc). Also the temp card is tiny and doesn't require any extra power. Sometimes it will get into Windows and then I will get vertical color bars on the screen and it's just dead (pic later, but I haven't been able to verify this result with the temp card, haven't gotten past BIOS with it). Also, it would become more and more frequent (card heating up??). The no screen image made my suspect the video card, but swapping hasn't helped so far so I'm really stuck.

Definitely sounds like a flaky PSU. Just because it's from a quality brand doesn't rule out the possibility of a lemon...

I had random post codes on my motherboard when the PSU was dying; take those post codes to mean that certain parts are not getting powered and are thus reading as failed.

If it isn't the PSU, then it is probably the motherboard. There are only two ways I can conceive that you would damage a CPU under normal installation and operation: excessive heat and bent pins. You were grounded when you put the computer together, right?

[TheGhost]

Is there a way I can check the PSU with like a multimeter or something?

So also, now I am just running with the CPU and one stick of RAM, and it barely does anything. This kind of boils it down to PSU, mobo, or CPU.

PSU I could go to Best Buy, get a shitty one, and return it before 30 days (this is exactly what I'm doing with the GFX card). If it's the CPU or mobo, I'm gonna have a bad time.

I'll admit, I don't know a lot about the internals of power supplies; someone else on here probably knows more. However, I did look up some information.



Their test system with a GTX260 shows as using 270 watts of power under load. As long as the 12v rails can handle what the card's drawing, I don't think there should be a problem...

Is this your power supply, then? OCZ StealthXStream 600W SLI-ready power supply? Here it lists it as having four 12v rails each capable of 18A (64A total). I suspect that's more than enough to run a GTX 260; BFG Tech's factory overclocked GTX 260 reads "525W PCI Express®-compliant system power supply with a combined 12V current rating of 38A or more (Minimum system power requirement based on a PC configured with an Intel Core®2 Extreme QX9650 processor)"

Based on that, I'd say your power supply isn't the problem, but I'm not a final authority by any means.

EDIT: Didn't see that maximum 36A, 155W you say was on the PSU's box. Probably means the GPU runs off of two of the 12V rails. However, that also would mean there are two other 12V rails for running everything else, so the processor and hard drives have their own set of rails to run off of. Sorry to say I can't really give a definitive answer.

Thanks for the enlightenment Varmint Also yes thats the exact power supply I have.

I have no idea what rails are, I assume "lines" of power?

Edit: Aha! http://www.computerplanet.co.uk/cust...4x2/step1.html

Under power supply section, it has this:

For the latest graphics cards the minimum requirements are as follows:

ATI 4850/4870 - OCZ 500W
ATI 4890 - OCZ 600W
ATI 4870 X2 - OCZ 700W
NVIDIA GTS 250 - OCZ 500W
NVIDIA GTX 260 - OCZ 600W
NVIDIA GTX 275 - OCZ 600W
NVIDIA GTX 280/285 - OCZ 700W
NVIDIA GTX 295 - OCZ 700W

SLI
2 x NVIDIA GTX 260 - 850W
3 x NVIDIA GTX 260/280 - 1250W

Not sure how reliable this site is, but it means minimum, therefore it should run (boot up, genreic Windows usage), it could hick up on demanding stuff though

[Warsaw]

This is what Limited has (Ebuyer doesn't give enough detail in the specs). So yeah, it should be more than capable of handling his system unless it's flaky.

I still think it's the GPU. Can you give us some POST codes?

[Limited]

Post code on the DEBUG LED from mobo is "FF", meaning fully functional or something about passing first few tests. I do hear the hard drives spinning up, nothing happens as I have no OS installed. So I believe its booting up okay, cant be sure because no output to screen.

Hopefully in a few days company will send me a new one, and tell me old one was broken, if it worked then crap I'm stuck.

Under returns, it says "direct replacement", do you think they will just swap old one without testing? Even though there policy is to test them.
