I've been having this problem alot recently and it's driving me NUTS.
I have access to 2 PCs.
1. A oldish work PC running Windows 98 SE
P3 550 Mhz
256 MB RAM
2 GB+ Free on the main drive
2. My personal PC running Windows XP Prof
P4 1.5 Ghz
512 Ram
10 Gb+ free on the main drive
I get this problem in two areas. The first area is the Cathedral's 3rd floor. All other floors are fine. If I go with NPCs or without NPCs, it crashes. You click on the button 3, the elevator's arrow moves, the loading cursor appears and then boom, error. This happens on BOTH pcs.
The other area is the Military base. It will crash on returning to the first floor after setting the self destruct sequence. Sometimes, if I go from the first floor to outside and return to the first floor, it will crash. Also happens on both pcs.
I've reinstalled, I've used both versions of the patches. I've recreated the game and following (how to beat the game in 20 mins), I will get this problem if I goto the military base first and set the self destruct sequence and try to go from the 3rd floor to the first floor. Crashes....
I once I got the game to let me get to the first floor at the military base and I made it outside. I got past the guard and watched the little cutscene. I made it to the cathedral and as soon as I get to the life in the basement. Crashes when I get to the 3rd floor. This is driving me NUTS. I've given my friend my save game and he tries it on his Windows 98 SE machine. It crashes in the same damn place.
I want to finish this game. I've played it so that I'm level 21 with the hardened power armor and the turbo plasma rifle... I've got all the call sniper perks and I just want to take on this master... yet I can't even get close!
Any suggestions?
Oh, the error the Windows 98 SE PCs will get. "This program has performed an illegal operation and will be shut down". Turns out the falloutw.exe performs "some error, I forget" and tries to get it on with kernel32.dll...
