Replace the 4 small caps near the CPU socket. These are counterfeit lytics that ECS liked to use.Main rig:
Gigabyte B75M-D3H
Core i5-3470 3.60GHz
Gigabyte Geforce GTX650 1GB GDDR5
16GB DDR3-1600
Samsung SH-224AB DVD-RW
FSP Bluestorm II 500W (recapped)
120GB ADATA + 2x Seagate Barracuda ES.2 ST31000340NS 1TB
Delux MG760 case

Re: ECS P4M800Pro-M Ver 2.0 No display
You can do the followed tests:
- To test if monitor works: use other monitor to your PC and use your monitor with a different PC
- To test if you PSU works: use a different PSU
- To test if you have graphics problems: you other PCI graphic card
Good Luck!

@ Hkskiller: whatever the outcome, O/P hasn't reported back in almost 2 years, so probably start over with your motherboard.
1st... a bit of history on your motherboard.
- Did the symptoms appear "out of the blue" - i.e. did the motherboard stopped working while in your possession. If not, and this is an item you got from someone else, ask about its history, if possible.
- Knowing with what hardware and up until what point the motherboard was working is helpful to know here.
2nd... what was checked on your motherboard.
- Did you try different (and known good) RAM? PSU? GPU? Monitor? Compatible CPU? (Check the manual!)
- Checked CMOS battery? If not, remove it and try booting without.
- Checked jumper settings?
- Checked for damaged traces (due to mishandling?)
3rd.... if all of the above checks out, time to take a multimeter and start measuring.
- Check all major voltage rails on the motherboard: i.e. CPU V_core, RAM Vdd, RAM Vtt, Vcc AGP, NB/SB Vcc, secondary standby voltage (3.3V/2.5V/1.8V - varies with motherboard and some have more than one).
4th... POST card test (if you have one.)
- Insert a POST card and see if it spits out any codes. If it sits at "00" or "FF", it means your pre-CPU initialization is getting stuck somewhere. Could be due to a bad BIOS/CMOS. Could be due to bad connection on CPU socket (either CPU to CPU socket or failed BGA on CPU socket - especially if the motherboard used a stock Intel cooler, as these tend to warp the crap out of many motherboards.) Could also be bad connection in RAM. Could also be a missing power rail... which is why you need to check #3 above first.
- Make sure to test the POST card in all PCI slots. Not all PCI slots will allow it to display codes, at least IME.Last edited by momaka; 09-01-2019, 07:52 PM.
