My z620 fails to boot sometimes (frequently) and it is hard to get it to work again...

[ibach2]

Every time it fails to boot it is a nightmare to make it boot again. Usually I get it to boot after countless tries from bootable easy2boot stick. I do chkdsk /f on c drive, and miraculously it works again. The only error I have ever found was the last time it happened. Chkdsk found that some area of disk was allocated as used, and was actually empty. It rebooted to windows after that and works normally until next failure i guess.

What could be the cause. It happens after the updates sometimes, but randomly too when I turn it on again...

The disk is PNY SSD of some sort.

Please, help!

I already did bios reflushing using the Crisis Recovery Jumper and USB,

reintalled the os

changed from mbr to raid achy

installed all the latest drivers (119 of them) manually...

Changed from PNY to Kinston SSD.

It just keep happening.

The only thing I did not do is change the power supply...

Ibach2,

This is a complicated situation as there have been so many actions.The mention of both flashing the BIOS and using the crisis recovery jumper are in my view are fairly extreme measures.  Was it determined that the BIOS was corrupted?

1. Boot to BIOS and reset to factory defaults

2. Install a known working mech'l HD of a capacity larger than the OS drive and set to GPT partition. Remove any other drives so only the Kingston SSD boot drive and the newly installed HD are present.

3. Try cloning the SSD to the new HD.

4. Defrag and run a cleaner, but be very careful with the registry cleaning, for example don't delete any old version of NET. Framework or better at this stage, not to fuss with the registry

4. Connect the HD to SATA0

5. If it boots and runs normally, continue updating drivers, updating the OS, and defragging

6. Clone to a new SSD in a GPT partition

However, given the situation, consider a fresh, from the beginning approach:

1. Ensure having a  fairly complete disk management software installed that can format, change partition type, and clone drives.

2.  Install a known working mech'l HD of a capacity larger than the OS drive. Remove any other drives so only the Kingston SSD boot drive and the newly installed HD are present

3. Boot to BIOS, reset to factory defaults, save and exit so as to>

4. Continue to Windows

5. If possible, get a SMART report on the SSD condition

6. If the SSD will not make a SMART report, or there are errors on the drive for example that it's reached it's read or write limit, replace it.  Consider replacing it anyway,..

7. Using the Disk management program >set an active, GPT partition on the HD of slightly smaller capacity than the Kingston SSD, or far preferably, a new SSD.

8. Install Windows on the HD

9. Boot and run Windows

10. If behaving properly, update Windows as fully as is practical, usinge defrag between large updates

11 Install the disk management program

12. Install the SSD, delete the partition> create partition volume > set to GPT, set to active but the cloning software may actually delete the partition, set a new one and set active automatically later

13. If the original SSD, get a SMART report on the SSD condition

14. If the SSD will not make a SMART report, or there are errors on the drive for example that it's reached it's read or write limit, replace it. 

15. If it 's good > Run CHKDSK on the SSD

16. If there are no errors on the SSD>

17. Clone the new Windows drive to the SSD

18. If there are errors, replace the SSD

19. Load Windows, drivers, and programs on the New SSD

I hope others will offer alternative recommendations, especially diagnostic ones or better yet, that one magic setting that will make everything work. It is difficult to make judgements without seeing all the screens and behavior.

Let us know how it's going.
