[Pavendaxx]

im having this dpc latency and its really annoying, it always destroy my mood when im gaming because that fps drop spikes and stutters. The most annoying thing is when im producing music and making music, it always ruin my mood because the audio is stuttering.

 

here are things i have tried to solve this problem.

 

things i have tried

1 change power plan
2 disable dynamic ticking and update graphic card driver
3 update driver
4 install chipset driver
5 disabling every network device adapter driver
6 disable other audio device driver
7 adding perflevelsrc, powermizerenable, powermizerlevel, powermizerlevel ac, to regedit
8 removing my old hard drive (7 years old 320gb wd blue)
9 change to legacy to ahci
10 reinstalling graphic driver
11 reinstalling audio driver
12 removing any overclock
13 disabling hpet windows
14 disable power saving feature bios

I think the problem caused by my old antec PSU, because i have been tweak some settings but nothing changed its still broken. So does bad psu can cause dpc latency?
