Help Diagnosing 7800GS Problem! - Page 5

OK, here's the deal, I am at a friends house right now and I tried my card in his computer. Guess what, it works fine and I don't know why. It worked for ~30 minutes anyways, which is longer than I ever had it running on HL2. His computer is ancient, 1GHz socket A cpu... Anyways the card is fine, it just must be a hardware compatibility issue that nVidia doesn't know about. What chipsets do you all have who are having this problem? I have 875P northbridge and ICH5 southbridge. Hopefully we can figure this out.

For a small update, on the box for the card, under system requirements, it says "One available hard disk drive power connector from power supply that is connected to nothing else in the system." So yesterday I took my HDD off of the line that the video card was on to make it the only thing on that line coming from the PSU. It seemed to have worked, because nothing was crashing anymore, but since then I've had it crash in HL2 and FarCry, but it was only after about 20 minutes that it locked up, a much longer time than before. So now I am going to have fun re-installing DX9.0c and OpenGL to see if that magically does anything. I have tried almost everything I can think of to make this card as happy as possible, it had better appreciate it.

It seems as though I have everything worked out. I have been running FarCry at 1680x1050 with HDR on, hasn't crashed since I brought it back from my buddies house. HL2 hasn't crashed, and I got a sick 3dmark05 score, Linky. So I guess having the card on its own power line, and having re-installed everything that has anything to do with graphics or chipsets fixed whatever the problem was, then again, there is always a bit of magic.

Rock on budy.

Great minds work together!

I'm glad you got it working. Great job!

So this topic is pretty much dead, and so is my card now. It started crashing to a black screen with looping sound anywhere from 5 to 30 mintes into any 3d application or game, except in FarCry for some reason. Anyways, I was reading a ton of forums, mostly the eVGA forums, and there were about a dozen people with the superclock and CO versions of this card who were having the same problems I just described, most if not all of them got their card to work if they turned the frequency down to "stock" speeds of 375/1200. This is ridiculous because they (evga, xfx etc...) are selling these cards as "stable" at the factory overclocks, which they clearly aren't. eVGA was blaming peoples power supplies saying they werent powerful enough to run the "OC" versions of these cards because of the increased power needs. The part that bothers me is that all the cards, whether it be the stock or factory overclocked versions, have the same minimum PSU wattage requirement on the box. These companies should really post specific power requirements for each card and make it clear to the end user exactly what they need to run this card under any condition it could be in. 2 or 3 people in that thread (it was a long one) recieved their replacement cards (the superclock version 460/1350) and had them working at the factory speeds in the same setup they had with their old card, one guy even had it running on his generic 350W PSU that came with his $30 case. I really find it hard to believe that there are dozens of these defective cards out there, but all signs are pointing to that being the case. At any rate, I sent in my RMA request, we'll see what happens.

I've installed my eVGA 7800GS CO, and found that it would reset (blank screen for a few seconds, then auto-reboot) after a few minutes in any 3D-intensive games.

I thought it was a power issue, so I bought a 550W Antec PSU, even giving the card its own connector straight from the PSU. It's also not overheating, as it runs at about 43C ~ 48C.

I've installed both the Forceware that came with the card (81.something) and the newest ones online (84.21), with the same problem. I updated my BIOS and my chipset drivers to the latest, still same thing.

I'm currently reinstalling Windows on a separate harddrive, in hopes that it will fix it... any other ideas that no one has yet to mention? I'm close to just RMAing it, but if I do that, would I be better off sending to Newegg (where I bought it), or straight to eVGA?

Well Newegg will exchange the card only.
But i would think in you explain your problem to EVGA and put on a sad face they may do something for you in regards to the problem. ((possible upgrade for free))

You never noooo!

Ok, so get this; I reinstalled WinXP on another drive (blank drive, newly reformatted), installed all the new mobo and graphics drivers, installed Oblivion, and the game seemed to run fine, meaning that all the other 3D games I've been trying to run will probably work as well.

Grr. Is there any good way to check and see what other programs or drivers I have installed on my old WinXP drive might be messing up? I really don't want to reinstall XP, and the blank drive I used this morning is only 13gb, so it's no more than a test drive really.

Welcome to the club, I went through that exact process but I never tried re-installing XP. One other thing I found while searching around is that you should not check the box that says "fan always on" in coolbits, the 7800GS doesn't like that, it fixed a few peoples problems, but they were people getting blue screens, not lockups. I'm sending back my card tomorrow morning, hopefully I get a new one that can run at the advertized speeds.
