interesting problem, related to my graphics card (i think)
recently, i received an unusual error: my monitor swtiched off and displayed this message:
IS OUT OF RANGE
V: 23.1 HZ
although my computer remained swtiched on, it was rendered useless
more recently, this error messaged stopped appearing, and the computer simply froze; but still remained switched on
i thought this odd, so i decided to open my computer up and have a look. i focused on the graphics card (ati radeon 9800 pro) and noticed that the fan was covered in thick dust; it was also extremely hot
so, i removed the card and replaced it with my old one (nvidia geforce mx 440) and the problems have stopped; the computer seems to be fine
my only thought is that the radeon's fan has packed up, it's overheating and thus turning itself off as a precaution
does this seem logical?
if it is the fan, how easy is it to replace?
