My HP died - went dead - won't turn on - does nothing but take up space. While googling for a answer to my proglem, I found this web community. There in a thread was my answer. Thanks to that person sharing their own story, I am getting my computer fixed for free. HP has identitied a hardware insure with certian HP Pavillion and Compaq Presanios. copy and paste to get to this site.
It also covers problems with motherboard and bios updates.

Good find — that HP advisory has helped a lot of people. Before arranging service or paying for diagnostics, try a few quick, safe checks that narrow the fault to power, PSU, case wiring, or the system board.

Start simple: confirm the outlet and power lead, flip the PSU’s rear switch, look for any front-panel or motherboard LEDs, and perform the recommended hard reset/power-drain (unplug, hold the power button). Those steps are the standard first triage for a “dead” HP desktop. (h30434.www3.hp.com)

If that does nothing, isolate hardware: disconnect all peripherals and drives, remove non‑essential cards, then try a minimal bench boot (motherboard + CPU + one RAM stick + PSU). Test the PSU separately with a jumper/paperclip (or a PSU tester); if the PSU won’t spin the fan when jumped, it’s very likely the culprit. If the PSU runs but the board still won’t start, briefly short the two front-panel PWR_SW pins on the motherboard (a small screwdriver) to rule out a bad case switch or cable. (support.nzxt.com)

Do a careful visual check of the system board for bulging or leaking electrolytic capacitors (puffed tops or crusty residue). Visible bad caps reliably point to motherboard failure and are a common failure mode on older systems. If you see those signs, the board usually needs replacement or professional recap.

As pointed out, coverage and the applicable service program vary by model and region. Before spending money, check HP warranty/service status with your product’s service tag or serial — that will tell you if you’re eligible for free repair under any past HP service program. If any step above is outside your comfort or you find bulging caps, stop and get a shop or HP tech to avoid further damage or safety risk. (h30434.www3.hp.com)

A couple of important things on this extended warranty:
* It applies for 24 months after the expiry of the standard one year warranty.

* It doesn't seem to say it anywhere on the site but when you dig into the details I think you'll find that this only applies if you have an Intel processor. If you have AMD, the Bios hasn't been updated in a long time.
