Desktop HP Slimline 450 DT PC (Serial number [Personal Information Removed]) fails to restart. It turns on for a few seconds and turns off immediately. It is a desktop that I rarely use and just try to use it this morning but was disappointedly choked to find it going into turn on/turn off loop.
I thank you for your technical assistance and look forward to seeing some tips and recommendations posted soon.

Sorry for the bad news, but when a desktop does not remain powered on, you have few if any options for getting it working again on your own.
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself. You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.
But if it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do.
You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it. And the problem with that is, while HP does do repair work of some sorts on PCs still under warranty, they generally do NOT do repair work on PCs out of warranty because they are not a general purpose repair facility. You would have to contact them in advance to see (1) if they are willing to work on it, and (2) if they will provide you any kind of repair cost estimate.
Since you live in the U.S., here is a link to the HP Service Repair Centers:
If that link does not get you a useful page, then use the main HP link:
If you can't get assistance from HP, then you will have to seek out a local service facility to have them examine it for you.
