Boot problems

[paultfh]

System:
Epox 8rda3+
athlon 2500 barton
512 ddr
80 gig WD SATA
Radeon 8500

The problem started when I replaced the Radeon with a Geforce FX 5200 128mb video card. The computer would freeze when XP would normally be loading up. Sometimes it will hang on a black screen, sometimes it will go to a blue screen that says "BAD-POOL_CALLER".

I have replaced the original card and tried booting from an XP cd. When it says "Boot from CD ..." it just hangs.

When I try to go into safemode it stops on a black screen with a command line that reads "multi(0)disk(0)rdisk(0)partition(1)\windows\system32\ntoskrnl.exe"

I have tried different xp disks and also tried a NTLDR Fix boot disk, but I can't get anything to boot. I have reset the bios many times, and my boot sequence is set to CDROM then SCSI\SATA.

Any help would be greatly appreciated.

Perhaps your NTOSKRNL.EXE is corrupt, or missing?

If you can ascertain that this is the case do the following:

reboot PC --> tap delete --> enter bios, set CD to boot first --> hit f10 --> save and exit bios. --> put in windows XP CD --> run CD as if you're making a fresh installation of XP --> During the windows bootup you will see "R for repair partition", go to that, it will start a pseudo-dos recovery console --> You will be prompted to fix which OS --> press 1, and hit enter --> for administrative password input administrative password and hit enter, if you do not have administrative password leave it blank and hit enter --> type d: hit enter --> type CD i386 hit enter --> type without quotations "expand ntkrnlmp.ex_c:\windows\system32\ntoskrnl.exe" if done correctly you will get a prompt to continue --> type /y and hit enter --> if it works take out XP cd and reboot --> if access is denied continue to this step --> type C: and hit enter --> type CHKDSK /r --> checkdisk will now recover bad sectors on your hard drive and fix errors YAY!! --> this should fix your problem. It fixed mine yesterday =). If it does NOT then --> type FIXBOOT, continue with any prompt --> should be fixed now.
