Booted it up this morning and all i hear is some clicking noise and it no longer is detected by the bios and obviously my comp won't boot anymore. If anybody knows what the most painless procedure is to replace it (special direct numbers i can call) then let me know. I am gonna try to contact hypermicro (store i bought it from) first and then ibm. It was fine up to today although i did notice a grinding sound whenever I booted the comp up in the morning starting about a week ago. Maybe the freezing temperature (less than 20 celcious in my room) affected it.
