Power cut off with new mother board (8 posts)

Hi friends,

I just bought a Abit SG-72( chip set is SIS 964L) mother board support for the P4/478 socket, and fixed into the case. Connectd the HDD, Floppy, DVD,Keyboard,Mouse.properly and yesterday I bought a CPU (478 socket)P4/3G/ 800FSB fixed into the mother board.

When I switch the computer on it will come to the bios setting and in about i0 to 15 minitues automatically cut off the power before I do something else. Please can you explane me what is the problem and how can slove the problem

Thank you

Got a cheapie with some old stock? What power supply have you used? What RAM? Are you sure it is compatible with the board. Post back with lots more detail. Brand of everything, model, rating, etc. In the meantime, unplug HDD, DVD, floppy - just leave video, KB, mouse, 1 stick of RAM. Does it boot quickly now?

Did you fit the fan to the CPU corectly remove the plastic film over heating CPU will shut down the system

Re: Power cut off with new mother board

I agree with the previous poster - look like a classic overheating problem.

Carefully remove the CPU and inspect the fan-heat sink unit to ensure that sufficient but not excessive good quality heatsink paste is used. If you just remove the CPU from previous motherboard you must scrub clean the existing heat tape (which normally came with the CPU) from the top of the CPU and at the bottom of the heat sink using a soft cloth may be wetted with a drop of citrus based solven such as De-Solve-It and apply a fresh but thin layer of heat sink paste between the fan heatsink unit and the CPU. Reinstall the CPU ensuring the CPU locking levers are properly seated.

Cheers

Hi nimal,

I have exactly the same board and bought exactly the same processor and had the same trouble.i disabled the temp cutoff in the bios and every time i play a game my board overheats and my system crashes. I was curious what your outcome was in the end. I would be grateful for any reply.

Case air flow is also very important, ensure a healthy supply of fresh air through the case.

Go to the bios and disable CPU fan control, Power Supply fan control ie run everything at maximum, also ensure that the graphic card fan is running, the chipset fan is running, last but not least raise the threshold CPU and System temperature to 65 oC but do not disable them.

With a new more powerful CPU the power demand of your Computer change therefore don't forget to get a decent power supply of at least 450 watts from a named brand such as Antec or Thermaltake

Cheers
