My pc will not power up correctly bee...

Open your cpu cabinet .
Remove dust from motherbord circuit.
Pull RAM memory then refix it afdter clean dust from it.
Aslo check heating event of chipset.

Reattach all connection to motherbord and harddisk.

Also open processor fan and then processsor then refix both.

Some times beeping noise comes because of
overheating of circuit.you can put exctra fan for heating event.

Thanks for using fixya
Please rate this solution if it helps.

what type of motherboard is it? how many beeps are you getting. each motherboard uses a series of beeps to determine what your underlying issue may be. i suggest you power unit on and see if you get three consecutive beeps, one beep, two or one long one. fill me in on what you have as far as motherboard and the status of the number of beeps and we can resolve your issue quickly.

Good Luck!
