Game Crashes

[Conface]

Hello there,

I am having a problem with my new computer crashing during games, the crashes are just a crash to a black screeen, no error message or nothing. My system is running: Vista Ultimate x64, AMD FX-62 AM2, Crosshair mobo, Crucial Ballistix 2GB PC2-6400, evga 8800 GTX 768 MB.

The crash occurs during the game, it may be right away, or 15 mins into playing. Supreme Commander, HL2, CSS, Medieval 2 and others. I have all the newest drivers installed, have tried reinstalling Vista multiple times, the system is not overheating and I have tried changing the voltage and timing of my memory. I am out of solutions, can anyone help me out here?

Thanks in advance.

I had a similar problem with an x1950 where it would shut down the video display after some amount of time. Can you see if only the video is not working or if the system is crashing? When the crash happens try holding down the alt key and pressing F4. See if the computer will shut down and restart. I assume alt-f4 still works in vista? This way you'll hopefully be able to narrow down the problem. What kind of power supply are you running?

What is your PSU (brand, model and wattage)?

PSU is an Antec 650 Watt and the Alt+F4 does not work, but when I tried it in desktop it only brought up a window, not immediate shutdown.

Can you alt-tab out of them when they crash, or ctrl-alt-delete out?

Its most likely a PSU thing, what do the rails say?
Look on side of it, the amps rating next to the 12v, 5v, and 3.3v.
12V is the most important.

[Conface]

Not exactly sure what you mean here but I think I got it. The ratings are: 12v=19a, 5v=24a, 3.3v=24a

I remember reading somewhere that the PCI-E cables that someone had for the 8800 were not the right ones, can't remember the specifics, could this be the issue?

[JoeFriday]

PSU issue.

eVGA's site states that a 12v rail capable of supporting 28A is required.

Awesome, I have had this computer for two weeks and haven't been able to use it yet because of this stupid problem, I have tried two other boards and contacted evga support about this and no solution. Then I post on these boards that I stumbled upon and presto! Within 6 hours I know the problem, thanks a bunch man and I am definately going to stay around these forums, always wanted to learn about overclocking.

Thanks again!

Is it this PSU? Because if it is that might not be the problem. I'm not sure if at all in existence stands a 650W psu with that low a 12v rail. Thats why I think its this PSU. The OP stated 19A 12v rail, well the 650 TP Trio model carries 2 19A 12v Rails not one alone.

What kind of psu is that ?? That does not seem right for a 650 watt antec..If it is this one it is 19v X 3. Check and see if it has multible 12v rails..http://www.newegg.com/Product/ShowIm...2c+CB+-+Retail

ex jinx man~!! You owe me or I owe you a coke..

[Milkman]

lol nice post bud

[Conface]

It is that PSU, and I had just come back here to post again cuz I was looking at other PSU's and they all have the same sort of specifications. For example this is my PSU's stats: http://www.antec.com/specs/TP3_650_spe.html and here is a different PSU's stats: http://www.thermaltakeusa.com/produc...0117/w0117.asp I think it is the cumulative amps you were reffering to.

So close to solving this I could taste victory!! Any ideas?

[N64link]

It's your PSU, it doesn't have enough amps on a single 12V rail. I think you have to use two of the rails on the card but I don't know how. Ask the guys in the PSU section, they tend to know a lot about this stuff.

Good luck, man.

You have 3 19A rails which gives you 57A for 12v right? Wrong, it actually only 52A. Chances are that your gfx card is running on the same rail as your CPU, your mobo, or something else that is sucking too much power. Switch it to a different 12v connector (not one on the same line) and see if that changes stuff for you.

I don't know if they have which plugs go to which rails or not, but just try switching it to see.

Exactly. Check out the manual that came with the power supply, there should be an explanation of what connectors +12v1, +12v2, +12v3 go to...At least my Antec NeoPower 480w says so...not sure if they still do that.

[repoman]

The manufacturer wouldn't make the the CPU/24 pin connector on the same rail as the PCI-E.

[LC_STiK]

We'd hope so anyways. Well I guess if they did, it couldn't be ATX certified could it?

I can't remember if I'm getting this right, but I seem to remember that on a 3 rail setup, the CPU gets it's own rail, the mobo and HDDs are on one, and the PCI-x is on another.

So that leaves anywhere from 19A to 14A for his gfx, which should be more than enough for just one 8800.

Thanks in advance.

Did you ever run memtest? UBCD has everything you'll ever need except 3dMark and a DMM for testing your system.

Prime95 would be good too.

[Conface]

It actually doesn't directly say if 12 v goes to the gpu. It just specifies that one goes to the CPU and doesn't specify the other two. This is from the manual and from the writing on the box.

I haven't tried a mem test but I will right now.

The PCI-E power cables go directly into the PSU, so I doubt I can change which cables power the GPU.

Needing 28A + for rail to mobo seems kinda like a fat estimate by mobo maker really. But then again those 680i mobos are picky aren't they?

@eXclusive- why the avatar change? People didn't like your game day face?

From what I've heard they aren't the best at change.

I'll be interested what Prime95 and memtest have to say about his setup.

@Conface- focus on test 5. That and test 7 are where all the errors show up at when I'm OCing.
