A few days ago, my pc stopped working a LED on my motherboard was flashing (SB_PWR). I got some help and found out that it was my powersupply. I just rebuilt my PC with a new power supply and cleaned out some dust. Theres no LED flashing anymore; theres a strong LED light like a normal start up but now theres a buzzing sound or static sound with still no start up or boot up. I cleared the CMOS and replaced the PSU with no progress.
