Microsoft Windows 10 (64-bit)

Windows 10 was installed after it first came out.  Unit had vista when I got it.  Desktop is a AMD Phenom X4, 9150e Quad-core, 4GB System Memory, 500GB HDD, 64 Bit.

System is in a reboot cycle and I am unable to clear the error.  Should I scrub the tower and reinstall all software?

Hi @tonimarie2340, 

 

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you. 

 

I see that you are facing issues with your laptop One of your disks is at risk (SMART event)

 

Please try the following Troubleshoots steps.

Step 1

 

1.    Turn off the Unit.

2.    Disconnect the AC adapter.

3.    Remove any discs from the disc drive.

4.    Remove memory cards from the card reader slot.

5.    Disconnect all nonessential peripheral devices, such as printers, scanners, external hard drives, and USB flash drives.

6.    Disconnect the AC adapter press and hold the power button for approximately 15 seconds.

7.    Reconnect the AC adapter, and then turn on the computer.

Step 2

Turn off the unit and please press and hold the Windows key + letter B key and the power button together for 30 seconds after 30 seconds, 1st release the power button but keep holding the Windows key and B key for ten more seconds and then release these two keys If done correctly, you will see the display flashing once. Please attempt it thrice as this step and  Restart the unit

Step3

The unit has to be turned off, Press Win+ V while holding these two keys then Press the Power button, continue to hold all three keys for 30 seconds and then release the Power button first and then release these two keys Please attempt it thrice  and then you may get a Pop-Up CMOS Check and it will restart the unit 

Even if you don't get a Pop-up restart the unit manually after 3 attempts.

 

f something is wrong with your SATA AHCI controller, it can lead to the DPC WATCHDOG VIOLATION error. You may want to change the controller manually and see if the error goes away.

  1. Press and hold the Windows key + R. This will launch the Run utility.
  2. Type in “devmgmt.msc” without quotation marks, then hit OK to bring up the Device Manager application.

  3. Expand the IDE ATA/ATAPI controllers category. Your SATA controller(s) should be listed here.
  4. Right-click on each of the listed items in this category, then select Properties.

  5. In the Properties pop-up window, switch to the Driver tab and click on the Driver Details button. Another window should appear shortly after.
  6. Check if iaStorA.sys is listed as a controller. If you don't see it listed in the driver files, you may still proceed with this method, but the success rate is significantly lower. Click OK to close the window.
  7. Click OK, then click on the Update Driver button.

  8. When the new window opens, choose the Browse my computer for driver software option.
  9. Choose the Let me pick from a list of device drivers on my computer option.
  10. Select Standard SATA AHCI Controller and click Next. After the installation is complete, restart your device and see if the error is fixed.

What is the PC's product number?

 

I would definitely reinstall the OS.

 

That is one seriously old system and probably a broken OS.

 

You could replace the HDD with a 2.5" 7mm SATA SSD and get a fantastic boost in performance.

Those SSDs are about $50.00 on Amazon.
