Windows 10 Password problem in safemode

Hi,

For us to isolate the issue, we will need to ask you a few questions:

• Are you getting any error messages aside from password incorrect?
• What troubleshooting steps have you done so far, after being stuck in safemode sign in screen?
  
• What are you trying to do when you enter safemode with networking through msconfig?
  

Regards.

 

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

PC keeps rebooting, then stops...

This puzzles me and don't know where to start, or rather continue to troubleshoot. The PC in question has:

• Core i5 2nd Generation CPU (Sandy Bridge)
• 8 GB memory (2 x 4)
• 2 x 256 GB Samsung SSD
• 1 x 1 GB Seagate HDD
• 1 x CD/DVD drive
• 1 x 650W power supply

The PC runs W10 Professional 64-bit, version 1803. The last time the PC case had been open must be 2-3 years ego, but opened today. The PC had been moved about 9 month ego to its current location.

It has been pretty much trouble free, until last week. The PC starts up, boots Windows, presents the login screen, but by the time the credentials entered, the system reboots on it is own. After the second and subsequents reboots, it reaches to the point that Windows does not finish to load or it doesn't even start loading and just reboots. After "n" number of reboots, the system does not boot anymore.

Leaving the system down and shutting off the power switch for a longer time period does allow start up again. Entering in the BIOS at this time gives just enough time to get the MB and CPU model numbers and it reboots again.

Opened up the case both sides and verified that all five fans are running, as soon as the system is started. Disconnected all of the drives and started the system, the BIOS stated that "No bootable device found..." and back to cycling reboots.

Reset the memory, tried booting with just one memory card, remove/reconnect power cables to the MB and video card did not matter, the PC is cycling reboots.

There's not enough time to do any troubleshooting with the cycling reboot, the system does not have any beeps or otherwise indicating issues.

The plan is to reset the CPU and if that's not resolving the issue, replace the power supply. If it's still having the same issue, replace the CPU, MB and memory.

Prior to going there, does anyone have a suggestion how to verify the source of this issue?

TIA...
