CentOS 7 wont boot if the system is heated up

Re: CentOS 7 wont boot if the system is heated up
before you order new power supply, if you have a spare hard drive, I would mirror the boot drive on a spare and see if that solved the issue.
it very well may be a failing hard drive. it might stick when heated and not spin-up fast enough on boot

Thats good one! The HD is an old 3.5 sata and according to hddtemp it reaches a temperature of 48 degrees (which is too hot as far as I know)vl1969 wrote:before you order new power supply, if you have a spare hard drive, I would mirror the boot drive on a spare and see if that solved the issue.

I will try that as well, many thanks!
Re: CentOS 7 wont boot if the system is heated up
I had similar issue with one of my PC last year.
I thought it was windows issue as it run Win7 at the time.
when I reinstall windows and had the issue still I drop in a hard drive with Linux and it would work just fine.
so I got myself new SSD (have been thinking to get one for a while and it was on sale) load up windows on it and no issue.
plug the old HDD back, and got the problem booting again.
load up the old HDD with Linux Mint, the boot problem got better but still happend. thus , scraped the HDD and moved on. FYI, you might still have problems with power supply if it's too old, but if you have a newer HDD I would try that first.

Re: CentOS 7 wont boot if the system is heated up
Ok guys,
Here is so far what I`ve tried :
I swapped the HD and installed the system once again : same problem but this time after 2 times self rebooting I`ve got the following :
I boot up with a gentoo live cd and I ran the command
and I get :
Then I tried to stress the CPU with
and after 5 minutes with 100% CPU the system was still stable. Btw he never reboots by itself when on LiveCD or BIOS, only just after the GRUB menu when he tries to boot up the OS installed on the HD...
At this point I doubt that the issue is the power supply and I have no clue what else could it be...

Re: CentOS 7 wont boot if the system is heated up
You have not replaced the PS, so why do you doubt it is a PS problem.
Hard drives seeking put a higher load on the PS than a live DVD.

Re: CentOS 7 wont boot if the system is heated up
I doubt it because I think that if the PS has failures than it doesn't matter what you do, it will always reboot or shutting down, or am I wrong?gerald_clark wrote:You have not replaced the PS, so why do you doubt it is a PS problem.

Re: [SOLVED] CentOS 7 wont boot if the system is heated up
@TrevorH
You had 100% right! I replaced the PS and now its working like it should! Thanks a lot for your help!
I removed SOLVED as this is not solved. CentOS 7 keeps rebooting and / or freezing
It stops after the GRUB menu or with a black screen and blinking cursor or with the CentOS loading page and in both cases the keyboard is not responding and I have to force it with the pwr button!
The errors (in red) I found in the log are :
Any idea ?
Where can I get more detailed information ?
Thanks!
