|Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of your mboard. |
The term CPU is frequently mis-used.
The CPU is NOT your computer case and the hardware components inside of it !
The CPU is the processor (microprocessor) integrated chip on your mboard.
Computers do not normally automatically shut down and stay off without you having done that yourself,
unless the CPU - processor - has overheated,
or unless it's a laptop or netbook, you don't have the AC adapter plugged in, and the battery is depleted enough that it needs to be charged before the computer can be used .
or unless you have a desktop computer and have a failing power supply, or less likely, defective capacitors on the mboard.
They may Restart automatically however.
""hard drive initiate failed"
- the drive isn't being detected at all.
The bios Setup must be detecting at least one hard drive.
If it isn't....
- the hard drive is not connected properly or has a connection problem. If you have not been fiddling with the cable connections to the hard drive, or if it's an IDE hard drive, if you have not been fiddling with jumper settings on IDE drives, then that's unlikely.
- the hard drive MUST spin when power is connected to it and the computer is running . If it doesn't either it's dead, or on a desktop computer, the power supply is defective or failing.
- the hard drive has failed, There's nothing you can do about that yourself if the bios Setup can't detect the hard drive(s).
If the hard drive(s) is(are) being detected by the bios Setup....
- at least one internal hard drive must be bootable.. At least one hard drive must have an operating system installed on a partition on it in order for it to be found bootable. If it's a new hard drive, it has no data on it, and it's not bootable. . If it's a used hard drive that has had it's operating system deleted or if it has been wiped of data, it's not bootable.
If it DOES have an operating system installed on at least one hard drive, if it's not being detected as bootable.....
- the bios Setup Boot Order or similar settings are not correct. Have you been fiddling with settings in the bios Setup ?
- you have more than one physical hard drive and the present settings in the bios are attempting to boot from a hard drive that has no operating system. The bios will NOT attempt to boot from another hard drive if the first one it detects by default, or is set to detect, is not bootable.
Is there more than one internally connected hard drive on your computer ?
- the hard drive is failing or has failed.
Run a bootable memory diagnostic test, such as a memtest86 bootable CD made on another computer.
If it doesn't pass that, there's probably nothing wrong with the ram if the SAME ram worked fine previously. Try re-seating the ram, then test the ram again.
Run a bootable hard drive diagnostics test.
Seagate's SeaTools will test (almost) any brand of hard drive.
Do the long test.
The Dos bootable versions of SeaTools can test the hard drive when Windows will not load properly, or even when the drive has no data on it.
It the drive itself passes the test, any data problems on the drive can be fixed one way or another.
"BIOS is not installed"
That's the bios for the drive controller, not the bios for the mboard.
If your motherboard has a drive controller that supports RAID, or if you have a hard drive or optical drive connected to a drive controller card in a slot on a desktop computer, the bios for that drive controller attempts to load first while booting the computer. If no drives are detected connected to that drive controller, a message "BIOS is not installed" or similar appears on the screen.
