Please help me. Im just a scandinavian girl with no knowledge aboute computers. well. i have runned memtest for some time (last time 7 houres) but the machine crashes, and i have to start over and over again.I then run memtest86 for 13 houres, no errors. i went in to "my computer" and changed the settings there. but all that happend was that when the machine crashed it did not come up with a blue-screene. it freezes and a red 3 cm line appears in the top of the screen. and i have to restart the pc myselve. I have runned diskcheck on C: it told me: filesystemtype = NTFS. Volume is clean and check is kompletet. It was ok. There is no dust in the computer. cables, and connections is ok.
