PC just shut down... ARGH!
More of a comment then a question... but comments are welcome.
PC is an ASUS P4C800EDlx mainboard running 512meg of OCZ DDR533 memory and a 128meg ATI Radeon 9600XT. CPU is a 2.6 P4 @ 3.19 (stable in all benchmarks since December - CPU never hits 50'C) Enermax 350w PSU. Played Doom3 for a couple of hours last night without any issues. When I exited the game the CPU temp was around 38'C so I don't think I was taxing the machine. Opened my OE to read the newsgroups and about 10 minutes into that the whole PC just shut off. Not fun. I could not get the PC to start regardless of what I did. Pulled the power cable and reattached. Disconnected hard drives. Pulled PCI cards. Reset CMOS. PC would just not post - no beeps - anything. Once I pulled the video card I got the standard "no monitor" beeps. I dropped in a Geforce 2 card I have and the PC is working again. Put the ATI card back in and no more boot. ***ARGH*** I killed my card! I pulled the Artic Cooling VGA Cooler off the card (no shim). No damage I can see. Compound right where it's supposed to be. No signs of overheating. I put the stock ATI cooler back on. Still dead. BAH!!! Left the PC in pieces for the night (it died 5 minutes before going to bed). This morning I power up with the ATI card in and it works fine again. (Had to reset the CMOS settings). What happened? Nothing was overly warm when I was pulling it apart last night. I didn't do anything this morning except turn the PC on. |

Thats just one of the scares built into the game. You get to a certain level and your whole PC shuts down. When you reach the top level , your keyboard locks up and your power supply catches on fire. All I can say is I havent had any problems so far with my ATI 9800 playing the game and it hasnt caused any problems so far in another system running an ATI 9000. |

Bahahaha.... Sounds like I hit the "hell" level early. : ) D3 is actually a bit more enjoying once I found the gamma adjustment in the cfg file. Still a bit linear for me though and there's no way to sneak up on the baddies even if you know where they are hiding (ie, toss a grenade down a staircase or around a corner and it won't touch any baddies there unless you've seen them and they've seen you). All I can say is I havent had any problems so far with my ATI 9800 playing the game and it hasnt caused any problems so far in another system running an ATI 9000. Something I noticed this morning is that the boot BEEP is pretty delayed after resetting the CMOS so I may not have waited long enough at boot while troubleshooting last night. |

I didn't do anything this morning except turn the PC on. The card worked fine again after removing and replacing it a few times. So, most probably the card became unfixed in the socket, or there was a bad contact at the connector. This happens more (essentially with RAM's). When replacing the card, I would suggest to use a contact cleaner spray and to control for a perfect fixation of the card (don't forget the slider!). |

Quality between different card manufacturers can vary a LOT even if they have the exact same GPU and other features. So if you don't have a reference card then saying "Oh, your ATI 9800 doesn't work? My ATI 9800 works just fine" doesn't really tell a thing. |

First off, I don't care how fast your memory is...512 is just too little amount for D3. 1GB of PC400 is better than 512 of PC533. Second, you're oc'd cpu is always suspect when it comes to PC shutdowns. Again, I don't care what the third party "stability" apps say, that is where there is risk. I have the same vid card as you and only a 2.26GHz northwood running stock and the game runs very smooth at medium(good enough for me). BUT, I have 1GB of PC3200 ram and that helps a lot. Take this for what's it's worth. Ron |

I have clocked it back a bit today. BTW, what is the BEST stress test for an OC? |

This morning I power up with the ATI card in and it works fine again. (Had to reset the CMOS settings). What happened? Nothing was overly warm when I was pulling it apart last night. I didn't do anything this morning except turn the PC on. Maybe the shutdown was the PSU overheating ? Did it actually shutdown or just attempt to reboot ? Shutdown could be the PSU itself doing it, or the thermal protection on the motherboard. If, on the other hand, the machine just rebooted (i.e. power was not lost), then that is consistent with losing communications with the video card, and the video driver taking a dump. As for the lack of recovery of the video card, I have run into a phenomenon like that once, but there is no matching root cause in your case. The GPU on the video card, could have gone into micro-latchup. But, I cannot see any mechanism to trigger it, in your case. For example, I've worked on a particular chip in the lab, where the chip appeared to be dead. At the time, I only had 15 prototypes, and couldn't afford for them to die. I turned off the power on the hardware I was using, and the chip would not recover. When I left the hardware unpowered overnight, the next morning the chip ran as if nothing was wrong. The circuit had no protection mechanisms, no overload protection etc. The root cause was bus contention (two chips driving a bus at the same time), which is what killed the chip. The consistent recovery of the chip, by waiting overnight, is still a mystery. A phenomenon called micro-latchup is the only thing that fits the symptoms, and before the latchup will release, the power supply has to be completely drained - something that may have occurred by waiting overnight. If this happens to the video card again, try shutting down the PC and then unplug it. Wait 10 minutes and plug it in again. Maybe that will be enough time for it to recover. If you read some of the reviews and info on Doom3, it seems to be quite stressful for the video card. It almost suggests that video cards are not being tested well enough when they are designed, to prevent surprises when a new video game is introduced. (I.e. A program like Prime95 or CPUBurn needs to be written for 3D graphics, by ATI or Nvidia, to make sure their video card is designed well enough for any application that gets used. There have been cases, where even processor designs have internal noise problems, that can be triggered by certain assembler language sequences, so ATI and Nvidia are not alone in this. Any chip with millions of gates can suffer the same fate.) On my ATI9800, I've noticed that one inductor (coil wound on a vertical cylinder) gets very hot. Using an after market cooler for a video card, may prevent air circulation around such parts. I recommend doing a touch test of the video card, whether you plan on modding the heatsink or not. While running 3DMark or some demo loop in a 3D application, run your hand over the video card components and see if anything is hot enough to burn you. Depending on how a third party heatsink is designed, it may prevent air from circulating near the hot component, actually making life for that component worse than with the original heatsink. In my case, I placed a spare 80mm fan I had in the adjacent slot to the video card, and the air from that fan keeps the inductor at a comfortable temp no matter what app is running. HTH, Paul |
