Welcome to HP Forums,

This is a great place to get support, find answers and tips,

Thank you for posting your query, I'll be more than glad to help you out 🙂

As I understand, your notebook is giving an error message "CMD.exe error SynCom.dll "

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

When was the last time it worked fine?

Were there any hardware/software changes made? 

Let's try these steps to resolve the issue: 

sfc /scannow

• To do this, click Start, type Command Prompt or cmd in the Search box, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

• At the command prompt, type the following command, and then press ENTER:  sfc /scannow

• The sfc /scannow command will scan all protected system files, and replace corrupted files with a cached copy that is located in a compressed folder at %WinDir%\System32\dllcache.

System restore:

1. Turn off the computer and wait at least 5 seconds with the computer in a full off state.

2. Turn on the computer and repeatedly press the F11 key, about once every second, until you see the Windows loading screen.

3. If a language selection screen opens, select the language you want to use to continue.

4. On the Choose your keyboard layout screen, select the keyboard layout that matches your keyboard type.

5. On the Choose an option screen, click Troubleshoot.

6. On the Troubleshoot screen, click Advanced Options.

7. On the Advanced options screen, click System Restore.

8. Click Windows 8, click Windows 8.1, or click Windows 10 as the target operating system.

9. The System Restore window opens.

10. Click Next.

11. Click the Restore Point that you want to use, and then click Next.

    The Confirm Restore Point window opens.

12. Click Finish to restore your computer to a previous point.

13. Do not interrupt System Restore when it starts. Doing so can corrupt your hard drive and create more problems. Click Yes in the warning that appears.

14. System Restore returns the computer configuration to a previous point in time and restarts.

Let me know how this goes,

Have a great day 🙂

Cheers 🙂

Hello and thanks for the response. It’s a desktop tower. It happened after I switched an electrical breaker off which the computer wound up being on. I tried all that you suggested and unfortunately it somehow lost all of my system restore points. Finally I uninstalled the Omen Control software, restarted and reinstalled via link I found on this forum in a different thread.

its working fine now so far. The Omen Control has been buggy in the past so hopefully this does the trick

Thanks!

Hello again 

Once again I have the dreaded Syncom error on startup. Omen central does work however in controlling lights on front of desktop.  In trying a “ repair” in Programs and features I found the path leads to a temporary folder 

C:\Users\Thomas\AppData\Local\Temp\pft455B.tmp\    Guessing this is why it will not repair

I have Omen Central 1.03. I tried reinstalling it several times

Thanks

Good Day. A warm welcome to the HP community. I reviewed the case regarding issues with Omen center.

I would suggest you to try a system restore when it was working fine. 🙂

2. Turn on the computer and repeatedly press the F11 key, about once every second, until you see the Windows loading screen.

4. On the Choose your keyboard layout screen, select the keyboard layout that matches your keyboard type.

5. On the Choose an option screen, click Troubleshoot.

6. On the Troubleshoot screen, click Advanced Options.

7. On the Advanced options screen, click System Restore.

8. Click Windows 8, click Windows 8.1, or click Windows 10 as the target operating system.

9. The System Restore window opens.

10. Click Next.

11. Click the Restore Point that you want to use, and then click Next.

    The Confirm Restore Point window opens.

12. Click Finish to restore your computer to a previous point.

13. Do not interrupt System Restore when it starts. Doing so can corrupt your hard drive and create more problems. Click Yes in the warning that appears.

Keep me posted. 🙂

I uninstalled and reinstalled and it’s working fine right now. Where should the files be located because on the repair option  in Programs it shows a path to a temp folder

C:\Users\Thomas\AppData\Local\Temp\pft455B.tmp\

Thanks!

As I said, it’s working fine right now but still points to the temp folder. Where should it be in files?
