Hi
*Power down the sytem
1 Remove vga card and ram
2 Unplug 24pin & *8pin [*if required by mobo] Power from Motherboard & Clear CMOS
3 Install minimal hardware: PSU; CPU & Heatsink; one stick of RAM and vga card [*boot to bios; If NO]
4 Use Spare compatible RAM and or borrow from a friend if possible [*boot to bios; If NO]
5 Use Spare vga card and or borrow from a friend if possible [*boot to bios; If NO]
Reseat CPU *do not over tighten heatsink [check for bent pins and or other damage] and repeat process 1 through to 5
[*boot to bios; If NO] check with another monitor and vga; HDMI, DVI and or other cables
*Double check all PSU cables are secure [fans not spinning on mobo; no sign of life * check with another PSU] make sure your PSU is registered within the thirty day limit; incase it fails or develops a fault
Assemble system out side of case place mobo on anti static bag and box lid [to ensure the hardware is not shorting out]
Note: If able to see bios on screen; go
here to update motherboard bios, once updated try with the original hardware config in the opening post
nb: try not to double post, use edit button if you need to add more information, thanks
Edit: attach system speaker so beep codes can be heard for mem and vga *if mobo gives errors
