i have had my amd athlon 2400+ for a while now however it only will ever run at a 1800+ ??? if i go into bios and adjust these settings so it will run as a 2400+ it will come up saying its a 2400+ but then it will lock and have to reset it sometimes it will get into windows and then lock up. i did have 768mb of ram but with that in it wont even start up on these setting?? it sounds like its loading but the monitor light just flashes and wont come on . the computer runs fine as a 1800+ but really want to get the full speed out of it. i think in bios it runs at 100/100 as a 1800+ but its when i change to 133/133 it doesnt want to know. another weird thing is that my old computer did the same and that was a 1.4 ghz but would only run as a 1.0ghz is it me and am i doing something wrong as am still learning, i have spent hours trying to sort it ..pls help ! my motherboard is a k7s5a if thats any help.
