Question Mobo stuck

[luka.lugonjic]

So recently I have upgraded my bios to a newest version and over time Ive heard beeping coming out from the inside of a pc. After reading online I thought it might be because of the bios update. So later on I tried to downgrade my bios which is not possible at least in easy way. I tried and created bootable flash drive with rufus and done everything with Afudos in DOS. After that when I tried to power on my pc it froze at the boot scren and couple of tries later I was able to get into bios which said thst my cpu temp is 267C. It also downgraded bios. After that pc froze again and I from that time everytime I turn on my pc there is no image at all. Monitor turns on, everything turns on but no image at all. Any help or advice? Thanks in advance!
Mobo: Asus p8h61/usb3
Cpu: intel core i5 2500k
Gpu: nvidia gtx 550 ti 1gb
Ram: kingston 2x4gb 1333mhz

What BIOS version did you downgrade to? The previous one or even earlier?
You need to be careful with downgrading a BIOS, as sometimes the newer BIOS version is crucial for some components to be detected properly by the motherboard.
Also, do you get a POST signal from the built in PC speaker? A beep, anything?

Hi, thanks for reply. I downgraded to the default version from 4305 to 0605. Chronologically from 0605 to 4305 and back to 0605. I used to but last two times I'm not getting POST signal. Amy advice?

Quick update: now I'm not getting any pictute, nothing. Monitor doesn't turn on or anytthing? Advices, help?

Do you have a motherboard integrated GPU? You could try plugging in your monitor there.

Unfortunately, no. I also do not have VGA output on my motherboard. Would it be worth it to disassemble everything and assemble it back again?
Thank you for sticking with the topic.

You can definitely "breadboard" and see what works and what not.
Get a piece of wood that you can put your mobo on or any other non-conducting surface. Then disassemble everything. Put the blank mobo on the board and seat the CPU (reapply thermal paste, if necessary), the cooler (including attaching the fan to the fan controller on the mobo), attach only mobo power from your PSU and the CPU power. Attach your graphics card and connect it to the PSU. Insert a single Ram only in the designated slot (check manual). Plug in the power switch button from your case, then plug in a screen and try to boot it up.

EDIT: Also attach an internal speaker, if you have one laying around.

I've read about breadbording. But what do you think, did I somehow damaged or have done something to my Bios chip. Would it work if I eeprom reprogram my bios chip?

How, if you cannot see what's happening?
I wouldn't go for that.

Yeah, but I was thinking that that could solve my problem because everything started with the bios downgrade and I think that my pc is not turning on because it didn't update bios second time properly.
Note: I upgraded bios to 4305 then went back to 0605 when I got over voltage and high temp and stuck boot screen and somehow afterwards was able to get into BIOS and immidiately I installed 4305 AGAIN and after thst I'm not getting any picture or anything. Does that make sense or something?

Anyone else thst can help me solve this?
