"dave" once tried to test me with:
It'll definately be the power supply - we had a problem with an nVidia card and a 450W PSU, the games ran OK but when playing Far Cry for two hours the PSU blew up (obviously the PSU was being overdriven and wasn't regulated poroperly) ! We now have a 750W PSU and everything is fine - If you wish to maintain cutting edge performance without continually replacing PSU you're probably better getting a 1KW PSU :-) holy **** -- Knight37 - http://knightgames.blogspot.com Once a Gamer, Always a Gamer. |

That doesn't mean it will supply the needed current to either the 12v or 5v rails. Another thing is that the motherboards own voltage regulators may not be enough to supply the needed current to the card. Remember, this is a 1.5v card. The mobo has regulator IC's for PCI/PCI-e bus or PCI and AGP buses. Your problem may not show up until the IC is loaded and hot. I haven't heard of Avus. I have heard of and use Thermaltake and Antec. I have a 420W and 430W in use on 2 different rigs, no problems with the cards I'm using. It isn't so much the wattage, but the actual current each rail is designed to supply. Both my PS's have all this info on a label on the PS itself. McG. http://www.avus.com/default.asp?PageNo=DEFAULT ... looks like they don't make this PSu anymore. It does have the big sticker visible on the side, but I can't understand most of the tech garble like you can. This mobo is an Abit IS7 ("regular" apart from other model types), know anything about it, or where I can read about those IC details? http://www.abit-usa.com/products/mb/...ies=1&model=79 Thanks for the help tho... -- Giant_Alex cravdraa_at-yahoo_dot-com |

Usually I find this stuff in the back pages of the user manuals, when it is there to be found. I've dl'd the manual for the ABit IS7 series and they don't show this information. 'White Paper' specs are harder to get for consumer items like add in cards and motherboards. Actual schematics are nearly impossible to obtain. I know what the regulator IC's look like and it's usually easy to tell if one is blown. It will have a burnt sooty looking spot near the case on one or two of the legs. This is getting way deeper than any normal consumer will ever go though. Troubleshooting at this level is very difficult for anyone outside the manufacturers production facility. I probably shouldn't have gone this way with you. There are other "likely suspects" to look at and account for first. And, at best, the most thorough process of elimination you can perform will not identify the actual problem. It may get you to the basic section, such as vid card or something in the PSU. Your problem can also be the video card itself. It can still be the PSU. Have you tried to use a different power cable connector than the one you have plugged into the card now? If it were simply resetting the system (arbitrary restart) would have me thinking video card. That it is shutting the system down has me thinking power. The only place you can really look is the PSU itself and any of its connectors. My thoughts on this include that you have already turned off some features that are known to cause stability problems with some ATI cards. I really hope this turns out to a simple problem with a simple solution, like a poor connection of the power cable to the vid card. Let us know what you find, ok?

Actually, the active components that may fail in DC-DC
downconvertor/regulators are not ICs, but power transistors. The associated capacitors may fail if subjected to prolonged overheating. Obviously a failed power transistor in a DC-DC downconvertor/regulator is not the problem for the original poster as after shut-down the system can be restarted successfully.

the 3 leg 7905 regulator 'IC' contains power transistor(s). I know what
you're saying, but i haven't seen any of the power transistors actually on the board in the traces to the slots. I have seen several of the regulator ic's. McG.

I will connect these fans to the regular connectors and then see what happens to the temperature inside the case. To anyone that is interested I disconnected the fan only connectors from my Antec power supply and connected the case fans to the regular power connectors. Motherboard Monitor now shows my case temperature about 10C less than before and the CPU temperature about 7C less. I now have my cpu fan set as slow as possible so it is quieter too. The temperature shown by the ATI video card is only 1C less but there the fan is also temperature controlled. Maybe I will give the Overdrive utility a chance and see what happens. Ak |

Phil, I figured out why it's correct of others about the power supply not being enough... It doesn't have a short because it works fine as it is without playing games... (found where that capacitor fell off from, the Ti4600) it is when a game uses the capability of taking over all the hardware as is possible via DirectX and OpenGL... the game will fill out all RAM that exists on the mobo and the vid-card, as much as possible. When that happens, the game as active is not a consciencious entity that is controlling what it does conc- erning all resources of hardware, it's just acting as directed and set. Too much software running when the game is full of it's own activities of animation, and there simply isn't enough power, the computer then shuts down as a failure because the game is not designed to control the resources. Therefore the game goes too far itself. A bunch of games I have will shut the computer flat off so a new 550 watt is on it's way. But I thank you for your great efforts to help, much appreciated, dude. -- Giant_Alex cravdraa_at-yahoo_dot-com |

I'm afraid that you rexplanation isn't correct.
Good luck with your new power supply. Let us know the results.
