Canadian Tech--error message "issue initializing HECI" at boot, sometimes won't boot

My brother who is a computer engineer and works in IT suggested it because he thought the power supply might be the problem.  He said that the 2.5" drives use less power and therefore might be able to boot more easily.  This is a temporary solution, and a test.  I have ordered a new power supply but because I live outside the US I won't be able to pick up the power supply until next month.  I hope to reinstall the original 3.5" drive once I have the new power supply installed.  Hopefully that was the whole problem. ?  It still boots a little slower than it should but previously it would not boot at all...  I also installed a new cmos though that didn't seem to be a problem until just the past couple of days (the date and time remained correct even without power until then).  Thanks for your help and advice, you have helped me with MANY machines...

There was a loose wire.  I had never thought to check.  Thank you!  This was a problem since I bought the machine a year ago...  as for the other, my brother has been giving me advice and I think it is a problem w the power supply.  I put in a clean 2.5" hard drive and was able to install windows 7 and it works much better.  It still doesn't boot as fast as it should, but it boots.  The 3.5" hard drive I took out seems ok too.  I smart tested it previously (crystal) and it came up good and I was able to download files from it to another machine without problems...  Thanks for all your help!

The command will automatically collect the computer files and place them on the desktop.

Then use 7zip to organize the files and one drive or drop box to place share links into the thread for troubleshooting.

This command will automatically collect these files:  msinfo32, mini dumps, drivers, hosts, install, uninstall, services, startup, event viewer files, etc.

Open administrative command prompt and copy and paste the whole command:

copy %SystemRoot%\minidump\*.dmp "%USERPROFILE%\Desktop"&dxdiag /t %Temp%\dxdiag.txt&copy %Temp%\dxdiag.txt "%USERPROFILE%\Desktop\SFdebugFiles"&type %SystemRoot%\System32\drivers\etc\hosts >> "%USERPROFILE%\Desktop\hosts.txt"&systeminfo > "%USERPROFILE%\Desktop\systeminfo.txt"&driverquery /v > "%USERPROFILE%\Desktop\drivers.txt" &msinfo32 /nfo "%USERPROFILE%\Desktop\msinfo32.nfo"&wevtutil qe System /f:text > "%USERPROFILE%\Desktop\eventlog.txt"&reg export HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall "%USERPROFILE%\Desktop\uninstall.txt"&reg export "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components" "%USERPROFILE%\Desktop\installed.txt"&net start > "%USERPROFILE%\Desktop\services.txt"&REM wmic startup list full /format:htable >"%USERPROFILE%\Desktop\startup.html"&wmic STARTUP GET Caption, Command, User >"%USERPROFILE%\Desktop\startup.txt"

There are two files for you to find manually:

a) C:\Windows\MEMORY.DMP

Use file explorer > this PC > local C: drive > right upper corner search enter the above to find results.

b) dxdiag: 

In the left lower corner search type:  dxdiag > When the DirectX Diagnostic Tool opens click on the next page button so that each tab is opened > click on save all information > save to desktop > post one drive or drop box share link into the thread

thank you Canadian Tech.  I will try to figure that out.  Do you agree with questions_ ?  I am cautious about using a cmd that I don't understand... 

  I did find the last 2 items he/she suggested, but they won't copy and paste...  well I guess the DxDiag would if it is open, but the memory dump won't, and I can't open it, I don't know how

The front panel problem sounds like a wire that is loose or missing.  Search for the case itself.  you may find some tips and instructions for assembly of the system.

One solution you might try.  I spent more than a year tracking this down on a system:

The SATA cable that connects from Mobo to drive.  The connection was not a good one.  I bought a new SATA III cable.  It has a clip that clamps the connection better.  These are not expensive.  Pay attention to the shape of the ends:   right angle or straight and length.
