My game seemed to be laggy, so i replaced my ram with my bros and it works better, then i tried my other bros ram, works fine. put my 1st bro ram in once again and I boot up my comp, asks me how i want to load it safe mode, recent setting, start normally, etc. i tried each one, it loads for a bit then flashes a blue screen with lettering on it. ive not seen what it says, because it flashes for 1 second then restarts again. but ive made my comp boot off the cd drive and i put in the windows xp cd. i tried to repair or reformat, but it shows a error. i think its the same one im not sure. it says: The problem seems to be caused by the following file: ntfs.sys PAGE_FAULT_IN_NONPAGED_AREA Techical information: **STOP: 0x00000050(0x82400000,0x00000000,0xf81c78fe,0x00000000 *** ntfs.sys - Address F81c78fe base at f8159000, Datestamp 3b7dc5d0 Thanks very very much if you have any answers.
