Doesn't post after removing CMOS battery.

[tommi_6o]

 

My friends pc wouldn't boot and it was giving an error no boot device found. I told him to go to bios and see if he could see the boot drive which he couldn't. Then he tried to boot from his old HDD which worked just fine. After that I told him to remove the cmos battery and wait 10 minutes before putting it back in and now it won't post. It turns on but there is no video out from the gpu or onboard gpu. There aren't any error leds or beeps. The system stays on and looks like it's working but no video out.

 

Things I have tried:

 

Mobo out of case, 1 stick of ram in every slot, different psu, reset cmos again, nothing connected to the mobo while out of case, reseat the cpu, check cooler contact, Mem OK button, all dip switches, I think that was all.

 

-Specs:

3770k

asus p8z77-v lk

2x4gb corsair 1600mhz cl9

r9 280x

 

Any help will be greatly appreciated Have a nice day and don't break your pc.

 

Edit: I have tried it with only iGPU

Tried unplugging the 280x and tried running out from the iGpu?

Try a different mobo, Socket LGA 1155.

lol... boot drive not recognized - better reset cmos

 

I think your friend zapped it with ESD and now it's dead

 

you do know that you have to put the battery back in, right?

[Bogdan_Dirlosan]

I don't have one

A little tip: when buying components (Mobos atleast) Buy a good one, and a really cheap one. IF one fails you have a temporary backup
