Asus P5K Deluxe RAM problem
Posted on 2007-10-02
I have an Asus P5K Deluxe mobo with two 1Gb DDR2 Kingston RAM sticks. Until last night everything was pretty much fine, but then suddently Win XP froze while I was writing an e-mail (outlook was the only app running) and I had to turn off the PC by keeping the power button pressed. After that the system wouldn't start, not even reaching the initial BIOS stuff and not even making the intial "beep". I tried a couple of times with no success.
This morning I woke up and tried again and I got to the POST messages, where it said that the overclocking settings were causing problems (I don't remember the exact message). I never overclocked this PC and all setting in BIOS are on "Auto" or "Default".
After that one time, again the system refused to even get to the intial "beep". So I decided to try to remove one of the RAM sticks and voila', the system started perfectly. To verify that the stick was defective, I tried to put it back in and take the other one out, and of course the system started up perfectly again... I tried to put them both back in together and the system won't start.
In summary: the system starts up with either one of the ram sticks but not with both together. Funny thing is that it used to run perfectly until last night.
How can I fix this?
