Press power button. There is no beep to begin with, monitor remain blank. All fans are running. led light on the front of the PC is on. I use a 7 in1 Ultra tester to test PSU and the only led light that did not light up is the -5v. The beep was crystal clear when i did the psu test. PC IS HP PAVILION, 3800 AMD Athlon/64 Processor, 1GB, 250GB HD,
What would be my next move??
