No beep no signal to monitor no power to keyboard and mouse

[Chairman]

Hello my pc starts up but doesnt do a beep and the monitor says no signal. I tried reseating the ram. Should i replace the cmos battery on the motherboard? The gpu and cpu fan is working and im pretty sure the ram works cause the pc turns on. I just dont know why it doesnt do 1 beep like it normally does when i turn it on. Btw the keyboard and the mouse also dont power up even if the pc is on. I need help please :<

You could reset CMOS, see if that works.

If not, can you maybe have a friend help you out with some testparts? Or maybe you have them yourself?

Sounds to me it is either your mobo, cpu or psu that is faulty.

You sure your gpu works and its just not displaying? if its not gpu then my guess would be as dylan said mobo or cpu.. also if you normally get post beeps, the culprit may well be your motherboard...  i mean bad ram will likely give you a post beep and its rare cpus are defective or bad without it being cause by a person. Could be your psu but only way to test that would be to connect yours to a different pc
