Solved Bios screen freezes on startup

[M1GU31]

The cpu fan is connected correctly and the heat sink is the big silver heatsink and the fan is on top of the heat sink it points up ^. The cpu atx12v connectors is 4pin and 8pin compatible i have to use the 4 pins. It lets me split them up to be able to use it on a four pin connector. Will check that the connections are properly secured into the mobo.

I see the CPU fan now.

It's too late now, but when I change a PSU I always count how many connections I pull off and make sure I reattach the same number when I put the new one in. A good alternative is to disconnect everything and remove any add-in cards (Video, etc) so you have a clear view of everything. Then attach power connectors like this:

1) Motherboard power connectors. They are buried deep once you get other stuff attached, so do them first.
2) Fans. I do them by order of importance, starting with the CPU fan(s).
3) Drives. Hard drives first, then DVD(s).
4) Stick any cards you have in there and attach power if needed (like the Video card).
5) Lighting, or whatever other odds and ends you have.

I'd also remove any "Y" adapters you are using for the power connectors and hook them up one at a time as you need them. For instance, if you have two SATA drives mounted near each other and are using a Molex-to-Twin SATA Power connector don't put it on until you're connecting the power to the drives. It's too easy to get a daisy chain of adapters which all plug into each other and don't connect to the PSU itself.

(Yeah, I did that once...)

If you hav'n't connected the power plugs for the graphics card, are using an onboard chip for display ?

I have read all previous posts, so answered my own question.

Same Problem.

I have recently run into the same problem. I disconnected me computer to bring to me gig. Connecting it to at me show, it booted fine, completely normal. Bringing it back to me house, connecting it back up... Booted fine. Shut Down. Next day, the problem began.

Me computer hangs in the POST SCREEN. Loads completely through the list of devices and then hangs. I can't command into BIOS, nor will it boot into HDD.

All devices work fine. (as far as I know)...

I sometimes /can/ get it too boot, but only with luck. Turning off the computer, waiting a bit, turning it back on.

I've also notice the Large case fan, on the side panel varies in speed (speeds up and slows down, but only when it will hang). When it booted normal, it runs at near constant rate. The side fan pulls power from the MOBO.

I'm thinking me MOBO has failed me, either that or it's shorting. I've gone through this forum and tried everything except, CMOS battery, and the mounting possibilities.

M1GU31 , What was the outcome of bringing your PC into the shop? did it end up being the MOBO?

Any help would be greatly appreciated.

(attached is a photo of me post screen)~ pretty sure that's the post screen, if not bios. please correct if i'm wrong.

Sorry about the super late post,just noticed it going through my emails but the outcome was that the mobo and cpu had been damaged due to a spike of voltage over 96volts over the limit with the old psu when I tried putting it back,they said they used some tool forgot what it's called to test out that stuff idk what they used.My mobo would just show the asus splash screen and it would just freeze right there with my old dead motherboard. Had to get a new motherboard and cpu but could only afford the same cpu and the new mobo i have is a bit faster then my old mobo. Everything started working when I replaced the mobo and the cpu. Eh kind of bummed me out and was costly to get fixed but the pc hasn't had any more problems and is working with the corsair supply I had gotten for it to replace the old no name brand one for my new video card. Hopefully in the future this will not happen again to me. Luckily it didn't burn out the ram sticks or anything else just the cpu and mobo which sucked,it still turned out but couldn't post anymore.Dudes said they tried to get it to post but they were 100% sure it burned it's self out,not totally but enough to get it to malfunction. The other reason they knew the cpu went bad is because they tried it with the new mobo I bought and it wouldn't post either so they tried with my old cpu with the new mobo and it did the same thing so with the new mobo and cpu it did post and logged into windows just fine.

Thank you for your reply!

I'm happy to announce that I did not have the need of finding a replacement. Me problem was simply a faulty multi usb-port... or perhaps something connected to it. Which at first I thought odd, I do remember booting with minimal devices connected. Only discovered after I bought it down to me local shop, they checked me hardware, no problems.

Lesson Learned: Triple check connected devices.

Odd, 2nd time in a week I've seen a USB device causing this.

Poor old power supplies. They are forgotten by many. Many don't even put them in their specs. No respect. To me it's the most important part in a computer. Everything else electrical/electronic in the computer depends on it. Your choice of a Corsair should serve you and your computer well.
