|This is a 5 year old custom built computer, probably 2.5 gig, 4gb ram, 4x HD's. First, the computer wouldn't start one of the HD's. Every time I switch on the computer I will hear the HD trying to start up and then shut down multiple times. This also affects another HD, so in total only 2/4 HD's work.|
A while after this starting happening, my computer began delivering a VERY high frequency sound. This sound will usually come on after the computer has been on for about an hour, and it's absolutely excruciating.
Any ideas on what this could be, or how it can be resolved?
