ERROR! And system shuts off

[NaryaMithrandir]

Hi guys and girls.

So I'm was migrating my pc to a new case, with the intention of installing a new graphics card (460GTX)
and an SSD for the first time (m4 128GB).


I've plugged everything into the new case other than the two upgrade pieces, as I wanted to go in and back up everything first.

But now when I turn the system on, it gives me this error:

floppy disk fail 40
cmos checksum error defaults loaded

I can go into BIOS or hit F1, but PC won't boot. It gives the error:

DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.

But then the system shuts off after around 30 seconds to a minute!!

These are the computer specs:

Nvidia NForce 750i SLI FTW (mobo)
Intel Core 2 Quad 9400 2.67Ghz
OCZ PC2 6400 Gold 2 X 2GB DDR2 1066
WD Caviar 500GB SATA 3.0 Gb/s (Primary)
WD 160GB (IDE)
Antec True Power Trio 550W PSU
BFG 7800GTX

I've disconnected the optical drive (an IDE drive) and the WD 160GB just to get rid of an IDE problem, but no avail. Problem persists.


What do I do?

I disconected everything but the MN CPU Memory GPU. I hit the CMOS Clear button. I then turned on the device

It runs into black screen and says it sees the CPU and memory and then says none to IDE and SATA's.

But then it says

Floppy DIsks fail (40)
CMOS checksum error degaults loaded

I can press F1 to continue or Del to enter BIOS, but I just let it sit there for a minute. It shut off in two minutes.

But now, it shuts off almost even before the system runs upto display the errors.

This is really confusing.

Also, don't know if this is important, but the POST code displayed is 7F.

Sounds like because you have nothing installed on the SATA or IDE channels/controllers and no offboard GPU that the system BIOS is defaulting to the onboard floppy disk controller. Enter the BIOS and disable all SATA/IDE and floppy controllers (ie, set = None), set the onboard GPU = Enable and see what happens. It may well be that you will have to connect your old HDD back in (and possibly also even the old GPU card). Whatever you do, first ensure that the BIOS settings align with the hardware configuration being used otherwise it appears that the system gets confused and attempts to initialize to default settings which usually includes floppy as first boot device.

I hit F1 and it gives me a DISK BOOT FAILURE message.

I let the computer sit for 15 minutes, and turned it on again. It stayed on while I flicked around the BIOS for a bit and turned off.

It keeps shutting off, anywhere between 10 seconds of turning the system on to 5minutes.

Wait, I AM using the old GPU and HDD. But the worse matter is that the system keeps shutting off now, not allowing me to do anything.

Also,it now gives the error that CPU settings have changed and that I should go into BIOS and enter stuff and save it.

Also it seems system clock in BIOS is stuck in 2007

Replace CMOS battery on the motherboard.

Because of what has happed you need to start from scratch. Pull the external GPU and LEAVE IT OUT. Reset the CMOS (pull the battery if you have to; replace also is a good idea too). At this point it would be best if you had a floppy disk to attach with a Windows startup disk. But if you dont, then you will probably need to put something on a controller. Therefore, put only your CD/DvD Optical drive on the appropriate controller (IDE/SATA? whichever you have; will assume IDE). With monitor hooked to the MB's video out, energize the machine and enter the BIOS. Configure the BIOS to match the hardware: Onboard GPU - Enable, SATA= None, Floppy=None, IDE=CD/DvD/Removable/Optical. In the BIOS Boot Order section set the IDE CD/DvD as the first boot device, HDD as second.

Restart using save settings and see what happens. If the machine shuts off then a guess is that you created a power supply issue when moving the system to the new enclosure.

Check that you didn't dislodge your CPU cooler when you moved parts around. If the computer is overheating, it will shut down.
