Computer won't start.

I switch on computer it starts the checking process before Post scree but, it continuously cycles round and round before the Post screen. Then after 5, 6 or 7 cycles it goes Beep then shows the Post screen.
1. What's causing this problem and how to fix it?

Suggest contacting ASUS or referring to your motherboard manual. The motherboard manual will have troubleshooting steps for boot issues related to the POST cycle.

to start with i'd look into what's making your cpu so hot . maybe you don't have the heatsink set right and it maybe shorting something out on your motherboard causing it to go into the loop your getting. just a guess but that cpu temp looks to high.

Thats what you get for using Arctic Silver.

Download and install CPUZ and Upload screenshots of the CPU, Mainboard, Memory, and SPD tabs.

Also, go into your BIOS and post all RAM and CPU Voltages and all RAM settings (timings, frequency, etc.)

Thanks to Dave76 for help learning RAM Stability

No Changes made.

See Below




I have also tried moving Memory around. It still cycles 6 times before loading Post page.

Memory settings look good. Try bumping the NB Voltage to 1.3 Volts and see if you have more stability.

CPU temperature looks a little high for idle. You may want to clean dust out of the system or reapply the thermal compound to the CPU and re-seat the heatsink/fan apparatus.

Have changed thermal paste she rides a little high on temps for some reason?

Could be the fan assembly is not highly rated for cooling. There is a high variance in how well certain fans cool the CPU; some do really well, and others are closer to the stock ratings. I have a low rated fan in my desktop, so my desktop runs a bit hot, too. I wouldn't worry about it unless the temperatures are getting to around 85-90 C during stress.
