Question about Asrock Computers & Internet
Motherboard does not start power supply. No fan works on MB nor power supply. Voltage between "power on" pins is 3.75 VCC. Does exist some fuse on the MB? How can I diagnose and solve this failure? Many thanks in advance.

Try this. Re-seat the video card, reseat your memory modules. Unplugg all USB cables. ethernet cables, power cables, and reset your BIOS by finding the reset jumper on your motherboard. Now plug in your keyboard, mouse and power cord. NO USBs, now try and start computer, it if starts replug USBs one at a time after computer is working. If no power up, are you getting any beeps? Possible causes for computer to try and start for a second and immediately power off.
1. Short Circuit (Motherboard touching chasis)
2. Bad power supply
3. Bad/stalled USB device plugged in.
4. Bad connection on Video Card / Memory Module (Corrosion?)
5. Bad Video Card / Bad Monitor
6. Look at the pins on the VGA connector and make sure there are none bend creating a short.
I hope this works for you!

Hi proenza. you're making good sence! You're D945GCL MB should be able to run 1066 FSB. Not 100% sure you're memory will keep FSB up to 1066.
Here's the trouble though. The Intel Core 2 Duo E6850 will not run on the Intel D945GCL motherboard because it is not supported. Look here at Intel's web site. Supported CPU's.
Intel E6850 specs sheet. http://www.dealtime.com/xPF-Intel-Intel-Core-2-Duo-E6850-Processor-3-0GHz-4MB-Cache-1333MHz-FSB-Conroe-Dual-Core-OEM-Socket-77
Intel E6700 spec sheet. http://www.dealtime.com/xPF-Intel-Core-2-Duo-E6700-2-67Ghz
This CPU is supported by the D945GCL MB.
Intel Core 2 Duo E4700 Processor BX80557E4700 - 2.60GHz.
In order to get 1066MHz (CPU can run at), you'll also need the memory support at 800MHz. The D945GCL MB can only run DDR2-667MHz.
Many people buy a CPU to run MB's specs (1333MHz) just to find the same MB does not support DDR2-1066MHz or DDR2-800MHz. Motherboard Mfg's are lagging. DDR3-1333MHz is out there now to support the 1333 MHz CPU FSB.
I hope this has helped you make a decision proenza.

If you don't already have a case speaker hooked up to the board, you might want to connect one since there isn't an on board speaker and you will not hear error beeps otherwise.
Also, if you have another non-phenom AM2 processor handy you should really update the BIOS to latest release. Many late model Phenoms will not work on motherboards that have earlier BIOS releases and you will not be able to post. You should then choose "Set Optimized Defaults" and save the bios without any changes then shut down (not reset). When you power on again it should post and you should be able to get into the BIOS.
A third thing you can try (after you get a case speaker hooked up) is using a cheap pair of ddr2-6400 RAM to get the board to post so you can get into BIOS and change the voltage to the correct settings for your RAM if it requires a higher voltage than the bios expects.
