I have a desktop unit that keeps shutting down unexpectedly after about 5 or 10 mins after booting up. I upgraded the unit to windows 10 about a year ago and also changed the mother board over as the first one had failed. The new mobo was a slightly better version of the original. I assumed that it was an over heating problem so I checked all the fans and they were all working.
I tried changing over the PSU unit but no difference. I then swapped out the graphics card - no difference followed by a brand new CPU heatsink and fan of the same make originally fitted - still no effect.
I used Speed Fan and could see that the CPU fan was only running at about 1550 rpm when it should run between 3050 and 600rpm - both the old one and the new one were doing the same so i guess i can rule out a heatsink problem.
Speed Fan said the CPU was about 55C at boot up and got to about 75 before it shut down.
I have checked the four ram sticks and they are ok.
If I boot in safe mode i can get quite a bit longer before it shuts down but shutdown it will eventually do.
Here are some specs:
MESH COMPUTER ABOUT 10 YEARS OLD 32 BIT
MOBO ; A8N-SLI PREMIUM
HEATSINK AK-856E
CPU AMD ATHLON 64 X 2 4600+
MEMORY 3071MB (333)
Any suggestions guys?
