I bought a sandisk ultra ii 480gb and installed it into my computer. My mobo is a Gigabyte G1 Killer Assassin 2. I was able to boot up normally with my old hard drive and I successfully cloned my old hard drive into the SSD. Then I went into the 3D BIOS UEFI DualBIOS menu and did the following:

I checked the Boot Option and it only showed my old hard drive. So I went and did Override Boot Option and selected my SSD. No change in boot speed.

I went back and tried to figure out whats wrong. Didn't know what so I selected Load Optimized Defaults. I then went back and looked at the option Hard Drive BBS Priorities and saw my SSD there so I set my SSD as the first, followed by my old hard drive.

I exited out and now... I see that my splash screen showing the G1 Killer logo is like only 75% of the size of my screen than usual and it hangs there. Theres like an interval of 30 seconds for 1 beep and after 2 beeps I think it leads me to a blank screen with a blinking underscore.

I decided to shut the computer down and unplug it and decided to read my manufacturers manual on how to reset my bios settings. Tells me I can either use a metal object like a screwdriver and touch the jumper for a few seconds to short it or remove the cmos battery. I tried removing the cmos battery for a minute and drained the computer by holding down the power button. I put the battery back in and started up my computer but no luck. Have not tried the screwdriver with the 2 pin jumper clr_cmos. Please help!

Also, I dont know when this happened, but my cpu fan stopped spinning. I know it was working before I started messing around in the bios settings. Also, my bios settings was set to AHCI.

Hmm, yeah I only waited for a minute. Ima try that and get to you. I dont have the jumper either because I lost it a long time ago or whatever, but I will try the screwdriver thing if the waiting 5-10 mins doesnt work. I need to be unplugged and I need to flush the power after taking out the battery right?

Right.. remove all power before removing the battery and follow with the power button pressed for a full minute., wait at least 5 minutes, 10 to be sure it resets, and put everything back on including a BIOS jumper on pins 1 and 2.. using the motherboard without a jumper makes it run in recovery mode all the time so that's probably what caused the issue in the first place...

Huh, weird. I have had this computer for a couple of years but I never saw anything resembling a jumper covering the pins. Also, the CLR_CMOS pins usually have 3 pins right? Mine only has 2. The manual also didn't mention anything about a jumper as a method in resetting the bios/CMOS. Also, does my CPU fan no longer running have anything to do with this?

I'm looking at the manual right now. It says that the 2 pin next to CLR_CMOS is where I need to "use a metal object like a screwdriver to touch the two pins for a few seconds."

Well, if there's only two pins... for Reset/clear_cmos, it must be designed like that... Where exactly are the pins? I'd like to find an image to see for myself.. that's if I can find one with good definition because most are to dark of have bad definiton.

I will try to get an image of the pins and the page in the manual. In the meantime, would unplugging the old hard drive and the ssd be a solution? I did change the legacy boot order or something like that...

It wouldn't hurt to remove one drive... but you said something like:
Theres like an interval of 30 seconds for 1 beep and after 2 beeps I think it leads me to a blank screen with a blinking underscore.
Click to expand...
Is that short and long beeps, how exactly does it beep?

EDIT:
If itbeeps once after the mobo logo, follows the BIOS post and then beeps quickly twice?... then remains blank with a blinking underscore?... that may be a failing boot dive

I start the computer, one short beep and shows the small sized splash screen. Can't press anything to go anywhere. CPU fan not running. 30 seconds later, a short beep. Repeats 2 more times. After that, leads me to a blank black screen with a blinking underscore. Here is the pictures of the CMOS pins, battery and manual page:

Right!!... the CPU overheats and shuts down in seconds for self protection if it doesn't have efficient cooling. So that is definitely the problem. Test the CPU fan power feed, try connecting the fan to the case fan power header,.. test the fan powering it directly, and replace it if necessary.

Okay, so I managed to successfully get the CPU fan running. Wire was faulty. But that didn't change anything. Still can't do anything on the splash screen, that is 50% size of the computer screen, and still get the blinking underscore at the end. So CPU overheating is not the issue. I also unplugged the ssd and left the old hard drive as is. That also didn't do anything.

The boot priority option would only affect the Windows boot... but the BIOS would post, you could access it, etc...
1. Depending on how long the fan was not working, and CPU overheating it's possible it may have suffered damage... if the BIOS never displayed, and the screen remained blank, the logo didn't display, buzzer didn't beep, etc... that would be a clear indication of CPU damage but it's still not clear. Removing the heatskink and thermal paste to see the CPU heat transfer plate overheated, burnt or heat spots should be obvious.
2. Another possibility is that the BIOS is dead but again the logo and beeps leave a doubt... so it's possible it's only corrupted and recoverable, and again... if the motherboard has a double BIOS it would automatically recover.

Suggested fixes:
a) Double check all data and power connections, see if the LEDs are working, blinking, changing color.
b) Reset the BIOS
c) run the computer with only one boot drive. Make it the one you are certain is working perfectly.
d) One more option would be to run the computer without a HDD and instead using a bootable disk in the optical bay.
e) If none of these suggestions works, the next step would be to flash the BIOS. The user manual should include a BIOS recovery or update/flash procedure.
f) A spare compatible socket CPU or motherboard would come in handy to test either. Running either on the replacement component would help diagnose which if any suffered damage.
