Hi, I have strange troubles on my comp and I don't know which program is responsible. But since PG is the most "lower level" on my comp, I try to ask here, and at worst if it isn't due to PG, may be someone will have en answer anyway. Often, When I load a game (whatever the one) all my runing processes crash the one after the other, by beginning by Explorer.exe, because the memory "can't be written". Yesteday, i have seen a very weird thing, I was reading a txt file opened with notepad, and sudently, the text disappeared and was replace with garbage letters coming from nowhere, and the title of the window was replace by "mplayer.exe" which is a program I have but which wasn't running at this time. Besides that, I 'm pretty sure my computer is clean. So what is the cause of all of that ? Is it a conflicts with a program ? is it PG ? Or have I memory pb and need to buy new RAM ? I add that when explorer.exe is crashing, it's always the same address value which use another one, and lead to the "memory can't be written" : 0x77f35f5f is using 0x01000000 for instance Any idea ?
