My four-year-old Pavilion desktop has for about six about six months started making a lot of wheezy noise about 15-20 minutes after I boot it up. This happened a year or two ago, and after much nastiness from and battling with HP, they agreed to honor the in-home service warranty I'd bought, and the guy came and made several replacements, including if I remember correctly the hard drive. Now it's happening again. Occassionally the machine will just shut down of its own accord, and recently, sometimes when I restart and try to enter my password the keyboard won't register, and I have to restart the machine several times before it will.
It just did this again, and when I tried restarting I got a message I'd never seen before, something up the somethingorother rear fan chassy not registering.
Considering the expense of the machine and the torture HP put me through about honoring their warranty, I'm loathe to invest in a new one, and four years seems an appalling short lifespan for a machine this large. Any thoughts?

Those symptoms indicate a "hardware" problem, probably the motherboard is starting to fail.
Not much you can do, other than to replace the motherboard with an identical one ordered from HP.
