No signal on monitor after attempted CPU change.

[letylerrs]

Hello everyone. Before I get started, here's the basics of my setup:
AND FX-4300 (old card)
AMD FX-6300 (new card)
EVGA GTX 1050Ti
750W PAY
GA-78LMT-S2

The issue I'm having is no display or signal on monitor on boot. Using HDMI. Have tried other cords, And is yes plugged in.
I encountered the error after attempting to change my CPU to the 6300. It sounds and boots like normal. All fans running, etc. But gives no signal.
Switching back to old processor, same thing now happens.
My gpu doesn't use a cord for power, just snaps in to mobo. I'm thinking I may have shot the motherboard during installation but not sure.
Any and all help is greatly appreciated

Clear the CMOS with the new processor in

Clear the CMOS with the new processor in

CMOS?
How do I do this?

Also I noticed: neither my mouse, keyboard, or WiFi adapter are receiving power/signal from the computer as well. So seems to be an issue with anything being plugged into it.

It may need a BIOS update to support the new CPU. Look on the site to see what BIOS it needs

Put the old one back in remove the battery on the mobo for a min then put it back in..

The simplest way to clear the CMOS is to remove the motherboard's battery for 20s or so. None of those items will work until the BIOS posts, so that's not unusual IMO.

Tried to remove mobo battery for 5 mins and reinsert, still the same.

 

[Paul NZ]

Does the mobo have video ports and does the CPU have integrated graphics??

If it does remove the videocard plug it into the mobo

 

[letylerrs]

Doesn't have either, Paul.

 

[Paul NZ]

Hmm what GP-78LMT is it?? There's more than 1

 

[letylerrs]

Wow I'm sorry, I apparently can't read inside my pc lol.
Mobo is a GA-78LMT-S2

 

[Paul NZ]

Hmm doesnt look like a bios update prob. The 4300 and 6300 need the same bios for both revisions

You may have bent a pin or something? Does it have a speaker on the mobo?

 

[letylerrs]

No speaker on mobo.

As I look at the 6300, it does look like a couple pins on the bottom are bent. But the 4300 is still flawless.

Possible I messed up something in where the CPU attaches to the mobo??

 

[Paul NZ]

I would buy a speaker. See how many beeps you get if it does turn on. It'll tell you what the prob is

If you've got more than 1 stick of ram turn it off try 1 stick at a time. One of them maybe faulty

 

[letylerrs]

Attempted ram thing. Didn't work

Update:
I tried to reinstall my old GPU to see if it was a gpu issue and it is not. Old gpu spit no signal either.

Left mobo battery out for 8 hours or so over night and reinstalled, still same issue.

Hmm.

 

[letylerrs]

okay guys, I have a question here about this that might be a resolution.

if I can't get it to POST or update bios via shorting 2 pins for cmos or removing battery, with 2 different cpus(the old one does the same as new now and both are on same BIOS revision), what should my next step be?

I'm thinking to use a different computer, download the bios file to a flash drive and to try and get it to post/update bios on startup that way. thoughts?? advice??

 

[letylerrs]

do believe the issue has been found. the 6300 isn't on my motherboards comparability post, so looks like I ruined the motherboard by attempting to use it

 

[Paul NZ]

The 4300 and 6300 are supported.

AMD FX-6300 3500MHz 1MBx6 8MB Vishera 32nm C0 95W 5200 F5

So I dont think thats the prob

 

[letylerrs]

then I'm at a loss on what to do.

 

[letylerrs]

anyone??? I've even tried to reboot with a flash drive containing most recent BIOS revision and it still won't give signal or anything to USB ports.
