|Instant FF post code Troubleshooting guide and video|
|Answer / Solution|
This guide will aid you in troubleshooting the FF, --, and 88 POST codes. For additional information and tips please also watch this helpful video!
1) Power Issues
-Improper Voltage Settings
Verify that the power supply is set to use the 110v standard instead of 220v. There is a switch on the back of most power supplies that will regulate this voltage. 110v is used in the United States, Canada, and most other North American countries. 220v is used in most European countries.
-8 pin and 24 pin connections
Verify that the 8 pin and 24 pin power connections are connected to the motherboard and seated correctly. Reseat the 8 pin power connection and make sure that no adapters, extension cables, or other intermediates are being used between the power supply and the motherboard.
-Uninterruptable Power Supplies (UPS)
If an uninterruptable power supply is being used verify that the UPS is rated to sustain the wattage and amperage for the power supply being used in the computer. Also try plugging the machine directly into the wall if a UPS is being used. This will rule out any issues pertaining to a UPS.
-Faulty Power Supply
If the previous steps do not resolve the issue it is recommended to try a different power supply with the machine to rule out any power supply issues.
2) Grounding / Shorting Issues
Ensure that standoffs are being used between the motherboard and the case, and the motherboard is not being screwed directly into the motherboard. Make sure that there is one standoff for each hole in the motherboard, and there are no additional standoffs making contact with the motherboard.
-Aftermarket Party CPU Coolers
If using an aftermarket CPU cooler that screws through the motherboard try unscrewing the CPU cooler and placing it on top of the CPU without screwing it down. If the screws are screwed too tight it can cause a shorting issue with the board that will cause it not to POST. Please note that this is for testing purposes only. Do not run the machine under normal use without properly attaching the CPU cooler.
Remove the motherboard from the case and place it on a non conductive surface (wood, cardboard, etc.). With only power connections, CPU, and CPU fan attached try powering on the motherboard. Please note that the machine will POST to an F6 POST code if board is POSTing. The F6 POST code will signify that there is no memory installed. If you receive this error you can continue to rebuild the machine as normal.
3) CPU Problems
Verify that the CPU is properly seated in the CPU socket and that there are no bend pins on the motherboard. If all of the pins appear to be intact try reseating the CPU in the socket and see if the motherboard will POST.
Make sure that the CPU fan is correctly attached to the processor and the fan header is plugged in to the correct header on the motherboard. If the CPU fan is not attached to the correct header on the board, or not attached at all, the motherboard may not POST correctly.
-CPU Dip Switch (790i FTW Digital PWM only)
The 790i FTW Digital PWM Motherboard (132-YW-E180-A1) has a tiny dip switch near the CPU socket towards the top of the motherboard. This switch toggles different power modes for your CPU. Leave the switch to the "1" position for Core 2 processors and above (Core 2 Duo, Core 2 Quad, etc.). For Pentium 4 or older processors flip the switch to the "ON" position. If this switch is set to the incorrect setting the motherboard will not POST and result in the motherboard going straight to the "FF" POST code without cycling through other POST codes. If the board doesn’t post and goes to FF automatically turn the machine off, flip the switch from the 1 to the ON position, and see if it posts.
If the above steps do not resolve the issue then it is recommended to try a different CPU in the motherboard to rule out any potential CPU issues.
4) BIOS Issues
-Improperly Seated BIOS Chip
Try pressing down on the BIOS chip of your motherboard to verify that the BIOS chip is correctly seated in the motherboard. The BIOS chip is generally located near the CMOS battery of your motherboard. Give the BIOS chip a little pressure to see if it will click into place.
Try clearing the CMOS of the motherboard by removing the CMOS battery from the motherboard for a period of time. You can also clear the CMOS by moving the clear CMOS jumper from pins 2 and 3 to pins 1 and 2 for about 30 seconds. After 30 seconds move the clear CMOS jumper back to pins 2 and 3.
