Computer Bios Issue

[Phobia]

So I'm hoping someone here might be able to point me in the right direction. I've googled my little heart out and I've finally hit a wall with what is going on.

So I threw a old pc build of mine back together to make into a home media center. Problem I'm having is pretty odd.

1) Bios is normally blue, it is now yellow and black
2) I threw win 10 ISO on a bootable USB to install windows. It will launch to windows 10 logo BUT its green and it locks there with no spinning dots
2) I then noticed, it's not picking up any hard drive whether set to sata or ide (and hooked up either way) Surely why it hangs, no where to install windows. I've tried two different known working hard drives.
3) I threw most updated bios on usb to flash the bios and it shows No BootMgr found.
4) Reset CMOS jumper and zero change

So a couple things are throwing me.......WHY is the bios color different......plus leading into windows being a different color (green win logo). Next, something is going on with Bios in general, it keeps seeing a floppy drive and there is no floppy in this build.

Anyone have any more ideas for me to run through. I'm about out of my own.

Re: Computer Bios Issue

So everything seems to be leading me to a power issue.

Current bios reading
Vcore - 1.3
Memv - 1.8
+3 - 3.3
+12 - 12.2

One thing I noticed, the bios doesn't even display a +5v rail. Now my question would be, did the bios never display a 5v reading OR is it not showing due to no power coming from the 5v rail so essentially its reading 0 and not displaying anything?

Re: Computer Bios Issue

Notice yellow color and no 5v reading

Re: Computer Bios Issue

My bios is black or grayish in color. Could be a few things.

1. Corrupt file on the flash drive.

2. Bad USB port.

3. The battery on your old motherboard has died and it's not saving any settings.

4. Power supply not working right.

Red is not a issue

Yellow I will check more in a sec, but I do believe it is holding settings.

Green is what I'm leaning towards.

My problem is that the bios appears just like this normally (blue background yellow text)


Whatever has occurred in this build has caused yellow text with black background. I can't even find a single picture online of someone elses bios looking the same way.

Re: Computer Bios Issue

So it gets a little more strange.

I decided to test and see if my CMOS battery was still good and holding settings.

Some settings hold fine and others change

1) Data & time = Holds perfect
2) First boot device = Always comes up as Floppy 1
3) I can disable floppy controller and remove floppy from the boot order and upon power off/on it will always put floppy controller back on and floppy as 1st boot device. The crazy thing, there is not even a floppy in this system. It doesn't even have a optical drive of any kind.

Re: Computer Bios Issue

I have a computer with 16mg of ram. One of the ram sticks went bad and having that still in there created all types of issues. Crazy Bios stuff that I never would have dreamed having a bad memory stick could cause.

I deleted a bunch of stuff, formatted hard drives, checked everything on the motherboard, etc.

It was brutal.


So I would check that.

Re: Computer Bios Issue

Threw a new CMOS battery in and boom problem fixed.......amazing that it wasn't just resetting the ever time I flipped the switch to power supply. Instead time would hold find even if I let power discharge for a while thinking thats how it was maintaining the time/date. Put new battery in and it instantly picked up hard drive and even no longer shows a floppy in the machine.

Strange strange.

Re: Computer Bios Issue

Yea, as soon as I saw the title of this thread, my guess was either the BIOS needed to be reset by taking out the battery, or you need a new one. Given it's cheap, going straight for the 2nd one isn't a bad choice. Any time you change the hardware drastically, the BIOS may not know what to expect hardware wise. You said you threw it back together so I don't know if that meant the same equipment, or just parts you had around.

See that is why I completely overlooked the CMOS. I reset the bios with the jumper, all settings reset like time and date. Once I set everything, I flipped the power supply switch, unplugged the cable and let it sit for a while to discharge any lingering power to see if the battery was bad. Turned it back on and the time & date held fine, that to me lead me to believe the battery was still good.

All the parts are the exact same but the power supply. I kept my 750w psu to use in my newer build and threw an older 500w in this build. Thing which was so weird about the "bad" CMOS, it acted as if different hardware was in it. Like it got "stuck" holding different in memory but the crazy thing its all the same parts, proc, mobo, ram, & hard drive.

Computers can do some strange things lol. Good thing, CMOS battery was only money I had to spend on this build. Threw Win10 on it last night and got my PVR all setup. It is working perfectly as my new living room media PC and will be the reason I cut the cord here in couple months (I want to test cutting the cord before I do for real).

Thanks for the help guys! We can go ahead and lock this up.
