Hello everyone
I have my PC for over 4 years and every 6 months i replace the old thermal paste with new one at GPU,CPU and chipset .
The last time I've done that process i try booting up my pc but a weird sound is coming off when i have my 4pin CPU power connector connected . When i take this cable off my pc works without this weird sound but ofcourse I have no display .
In conclusion: All fans work correctly , i have tried connecting only the 4pin,24pin and one stick of ram , i am sure i have connected everything correctly , I have reseat the GPU,CPU,RAM many times ! , I haven't done any upgrade everything is exactly the same !

MOBO: Gigabyte GA-G31M-S2L
CPU: Intel Pentium E5200
GPU: Palit nVidia GeForce 9500GT SUPER 1GB DDR2
RAM: 2 x Kingston 2GB KVR667D2N5/2G 1.8V DDR2
PSU: LPK9-4 500W
