I found this on my search for help for my (hopefully only temporarily) dead computer, and it seemed so useful that I thought I would try and ask for your help in reviving my computer - please?
It started failing last week - running fine but suddenly black screen and spontaneous rebooting which did not work. After shutting it down and switching back on, everything looked ok until, again, it suddenly died. Did this a few times, usually after 5-10 minutes it either froze or went to black and reboot.
I was trying to get my data off it with Synchback, and the profiles did not all run successfully (and gave a message about sectors and accessing), so people suggested that the hard drive might be failing. So I got a new one and put that in, but can't seem to get anything at all running - no Windows setup, no partitioning program, no clonezilla for hard disk restoring purposes. They all crash.
The hard drive, connected to my laptop, looks absolutely ok. Memtest reports everything ok with the memory. I can access the BIOS without problems.
I did replace the CPU fan last week just a couple of days before the first crash, but it looks to be running ok - computer reports a CPU temperature of anywhere between 29 and 50 degreed celsius at startup, depending on how long it has been running, obviously.
Any suggestions what it might be that causes this? People now suggest the motherboard may be failing, but if you can access the BIOS all right...?
I'd be grateful for any suggestions!
