BSOD 0x490 ("BAD_POOL_CALLER")

LordChristoff · 21 Apr 2014

I have recently been getting a problem with my PC where it refuses to start for no given reason. It started the other day with a BSOD error of "BAD_POOL_CALLER" which then proceeded to boot up at all. So I thought sod it and decided wipe the HD using an unmounted Ubuntu Disk and using Gparted formatted the whole HD to a fat32 file system to hopefully get rid of the driver which I thought was causing the problem. I then proceeded to re-format it back to a NTFS file system to then re-install Windows 7 back on to. The setup went as normal, but upon first boot up I get the error code "0x049" and the computer restarts itself. I have done a few things now including:

- BootRec
- Disk Check
- Repair Disk
- MemCheck
- CMOS Clear
- BIOS Reset

and nothing seems to help with the booting of this OS, did I mention that the HD works fine in another PC? So this leads me to think that the BIOS is at fault and it may be worth flashing the BIOS to a state where nothing could have been installed or updated to the BIOS.

Would you agree?

Just to clarify, the HD that I am using has Windows 7 on it. It will boot perfectly in another PC but refuses to do so in my own computer.

Hi LordChristoff.

How many HDDs are there in that computer? If there are multiple HDDs, remove the others and try to boot the computer again, at least as a test?

If the computer boots, that will be good.

If it does not boot still, or if there is no other HDDs at all, boot into BIOS. Set all UEFI elements to Legacy throughout the BIOS. Change to storage controller mode to AHCI, too.

Then format the HDD again. SSD / HDD : Optimize for Windows Reinstallation

Perform a clean install: Clean Reinstall - Factory OEM Windows 7

Hopefully everything should work then.

The problem was in the BIOS all along, in the advanced settings to how the BIOS. Somthing had changed the settings to control the SATA HD's with AHCI/RAID instead of ATA/IDE. This was and is the cause of the problems.

All I did was:

Start the computer > Go in to the BIOS > Go in to Advanced settings > Advanced Sata Setting > Change the device controllers to ATA/IDE. And it now boots fine.

Thanks for your help Arc, I figured this one out with the help of:
STOP: 0X0000007B (0xF78d2524,0XC0000034,0X00000000, 0X00000000) - Asus - Motherboards
