Andy S Posted December 4, 2009 Share Posted December 4, 2009 I'm completely at wits end. Over the past several months, I've had locksup within 5-10 minutes upon starting Fallout 3. I've RMA'd my GTX 260 twice and they've said they've run the card with multiple games for hours with no lockups. They sent the same card back both times, and claim they don't have another card to send me. During this time, I've replaced the motherboard (failure) and had three different OS's on the box (Vista 64, Win 7 RC 7100, Win 7 RTM). Whenever I have sent the card off and put my old 8800 GTS 320 back into the box, I can run Fallout with no problems. If I lower the GPU clock and memory speeds on the GTX 260 I can play for longer, but it still locks up. I went as far as to upgrade from the Antec Truepower 650 power supply to a Corsair HX750W (which cost as much as the graphics card in the first place), all to no effect. I had thought maybe it wasn't getting enough voltage since MSI claimed it wasn't a heat problem. Running the game at 1920x1600, high text, 4x, 4x. Trying lower 16:10 resolutions crashes (different than the freezes) fallout3.exe to the desktop. The only other game I have had any repeatable lockups with is Mass Effect, and that's pretty rare (maybe a couple of times an hour or so after starting to play). Over the last couple of days I've played Dragon Age for hours with only one freeze. Current System: Q6600Gigabyte EP45 UD3R8 GB DDR2 OCZ RamCorsair HX750WMSI GTX260Dual monitors (24" Benq, 26" Asus) 1920x1200 on bothWin 7 Pro 64bit Any ideas as to what to try (other than putting the 8800 back in)? The system is perfectly stable other than the random game lockup. It stays up for days/weeks at a time, and I can always ctrl-shift-tab or ctrl-alt-del out of the game lockups and kill the game. Apparently this game should have been bought for the 360 instead of the PC in my case. Between the PSU and the game, I could have bought an additional 360 Or another graphics card entirely.

Andy S Posted December 4, 2009 Author Share Posted December 4, 2009 After all this time, I just discovered something I think. If I have the game running on my main monitor, it's does as described above. In playing around with settings, I set it from within the Fallout 3 launcher to load to the second monitor. The game ran for 30 minutes with no issues. Any ideas what would cause this? Link to comment Share on other sites More sharing options...
