Hey there, so i have upgraded my old PC from this:
CPU - i3-2120
Motherboard - Intel H61 S1155
RAM - Corsair DDR3-1333 4GB DIMM
GPU - Gainward GTX 560 SE
Case bought with PSU (PSU no name) - GTT Hanava 545W Midi Tower With 500W
to this:
CPU - i5-2500 (used)
Motherboard - Same!
RAM - Additional 4 GB Ram Stick (new)
GPU - Sapphire AMD 280x (used)
PSU - Seasonic M12II-520 Bronze Evo Edition (new)
Main problem: all components working well with the system expect One thing when 280x is installed my PC won't even load windows or boot up somehow, i mean all parts are working in case, but monitor and mouse not even getting any signal from case expect PS/2 connected Keyboard. Tried with other GPU, everything works fine, CPU is working, Ram, PSU. So what problem could be? Motherboard? PSU? GPU?
What i have tried to fix this:
- When 280X installed remove new ram stick
- Connect two psu (one for gpu, other for system) but i need adapter (so i did nothing :D)
- Connect not all Pins to see if PC even can boot up when 280x installed but in boot menu it didn't showed nothing that gpu is installed (of course, gpu is not connected with all pins), so it means it can load without gpu and it's something wrong with GPU or motherboard i guess.
