desktop computer slow speed

Pavillion 590
Microsoft Windows 10 (64-bit)

I am have a Pavillion 590 with Windows 10.  A couple of weeks ago the power went out while I was on my computer, a few seconds later the power came back for a couple of seconds and then shut back off.  The screen was frozen and nothing worked.  I was able to shut the computer down but it wouldn't boot back up, it gave me the blue screen of death that it couldn't read the hard drive.  I was able to run some diagnostics and the drive was not damaged.  I got a reboot disk and reloaded windows 10 and got the computer running again.  It is very very slow, to the point where I am ready to either throw it away and get another computer, wipe the hard drive and reload it.  I have run diagnostics over and over again with nothing showing up as wrong.  After I got the computer up and running windows wouldn't find my other monitor.  I bought a program to update the drives and it did this and presto the 2 displays work again.  Windows update didn't find the correct drivers.  My computer is just slow.

Desktop computers are very sensitive to power surges -- which sound like what happened to yours -- and that can damage any component in the PC, including the hard drive.

 

This could simply be a problem with the onboard disk controller chip having been damaged such that disk reads now have a high failure rate and are being done over and over and over --which will slow your PC to a crawl. The standard diagnostics would not detect motherboard issues and would not be of help in that.

 

Unfortunately, I am not aware of any place that does motherboard diagnostics, so you are essentially stuck with this issue -- and since HP does not sell replacement motherboards, even if you do get someone to diagnose it, you will have a very hard time replacing it.

 

This is why I have my desktop connected through a surge protector -- as we often get power failures and surges during really severe thunderstorms.
