just recently i replaced a 56k modem in my friends computer. it worked fine...no problems...in a couple of days she asked me to come over and do a defrag....(she knows little about computers) i go over there to defrag her computer and the first thing i do is run msconfig and disable a lot of the crap she had coming up on her startup...not services..just the applications....i reboot and i get this stop message.. STOP: 0x0000008E (0xC0000005, 0x804E6BB4, 0xEF434744, 0x00000000). i did a repair install of windows xp because she said she didn't want to lose anything she had on there but i've read a few threads and realized it's something to do with RAM? When i saw this i went to her house and pulled one stick out...same message...put the other one back in...same message..put it this way, i tried every combination and got the same results. Just to make a note...She has 2x 256 ram chips. Now, on another note, the only way i can boot her machine is if i disable all services. I can also boot her computer in safe mode. One time i disabled all services but microsoft services and i got the stop message. Then i tried it the other way around (enabled all non-microsoft services and disabled the microsoft services) and it booted. i am stressed out because she calls me constantly. can anyone help.
