Some times simple solutions isn't what I want

After I posted a comment on my friend's blog, I realized when it comes to myself, many a times simple solutions is not what I look for. Here is one example for the same. 

I retired my old Athlon based PC and built a new Athlon X2 based PC. Everything was new including the hard disk and the OS and all. The PC was running fine for a few months and then started blue screening and complain "Insert OS disk and boot". I used to faithfully re format the disk and re-install the OS, until I realized I can solve the problem  by unhooking the SATA cable from the hard disk and the motherboard and re insert the same after some time (cooling time). 


Over time the blue screen became more and more frequent, it was like sitting on a time bomb not knowing when it will go off. I suspected the memory interface, so I slowed the memory speed in the bios. I downloaded memory stress test and ran the same, there were no errors in the memory interface. 

Since I had already invested too much money on the new PC, I had to fix it and make it stable. I debated on changing the hard disk. but I wasn't sure whether it was the hard disk or the motherboard that was faulty, I decided to ditch the SATA disk completely and installed the OS on an old IDE hard disk. The 80GB space on the IDE disk was not nearly enough to hold the pics and the music among other things, hence I decided to use the SATA disk for data. 


The instability of the PC got solved but every now and then the data disk would drop off and become unavailable. The only way to recover was to unhook the SATA cable and hook it back. I did some research on forums and based on those suggestions, I uninstalled the nvidia SATA drivers. This step did help to some extent and the data disk fail became less frequent. 

One fine day I realized I had an extra SATA cable and decided to swap the cable, I can't believe all my problems with the PC is solved. The fact is I had this cable for ever and could have done this long time ago but my logical mind couldn't accept the cable could be at fault, but turns out it was. If only I had taken this simple step in the first place, I could have saved myself a lot of agony. 

In hindsight I think the cable was failing as the temperature of the CPU box went up and the system used to blue screen once the cable failed. For a long time I had setting "Reboot on failure" and hence I used to get the error "Disk not found". Uninstalling the SATA drivers helped because the data transfer rate reduced and hence the heat generation reduced.

Well written manju. It took quiet a long time to fix the PC and your patience has to be appreciated.

Interesting. The moment I saw 'blue screen' I was going to say "Use Linux"!
