Aplologies for a rather long post. My 40GB Samsung hard disk has crashed recently and I replaced it with a new 80GB Seagate hard disk. I loaded xp home on it. Since the time I changed the hard disk, my computer has started freezing. I had this freezing problem even when I was installing XP on the new hard disk. Somehow I managed to install windows after a frustratingly long time. After I installed windows the computer started freezing, initially only when I ran Spybot or Virus Scan. Slowly, it started freezing at different points - at XP welcome screen, immediately after entering windows, a couple of minutes after entering windows, etc. It freezes even within BIOS in a few minutes. A quick search on internet revealed that it might be a problem of CPU over heating. I entered BIOS to monitor the CPU temperature and noticed that the initial temperature is around 60C but within a minute or two, it increases to about 91-92C and the computer freezes at that point. I have a P4 1.6 GHz processor with 512 MB RAM. My questions are:
(1) Is 92C very high for my CPU?
(2) Is there a possibility that higher capacity hard disk caused this over heating problem?
(3) Is spybot and virus scan freeze is related to CPU overheating?
(4) If I want to replace my heat sink and/or fan, can anybody suggest me how I determine what kind of replacement (specs for new heat sink and fan) I should make?
(5) Finally, is it too risky to get the heatsink changed by myself?
Thanks a lot guys,
