Updated my computer to a Hyperthreading chip now XP Home won't boo

[Guest]

I upgraded my chip from a 2.53 to a 3.06 Hyperthreading chip and now I can
only boot up in Safe mode. I have Windows XP SP2 Home. In device manager it
recognizes the new chip and I see two chips now a basic one and the one
saying Intel 3.06 under Processors and Task Manager shows only one chip now.
was showing two. I am going to reboot. I can only boot up into safe mode.

can only boot in safe mode. computer said it had found new Hardware a APCI
chip and it install the drivers.
thanks

Its ment to show two chips thats whats hyperthreading is,fooling the puter in
thinking its running 2 cores so thats normal. as for the not booting thing I
am unsure sorry.

when you boot in safe mode, a number of drivers are not installed. Its
likely that a driver was installed via your mobo install disk. The easy way
to fix is to do a windows repair via your windows setup cd. select new
install then repair installation found....

I suspect you will need to do an XP Repair Install in order to get the
multiprocessor hal installed. Then you'll need to reapply ALL the SP and
hotfixes (a real pain I'm afraid). I don't believe there's a shortcut
around this, but you could google around for "xp change hal" (w/o the
quotes).

To validate what you've got now, open Device Manager and expand the
"Computer" branch; under it you want to have a branch called "ACPI
Multiprocessor PC". If it doesn't say that then it won't use the
hyperthreading. I suspect yours says Uniprocessor.

Good Luck

Checked, it shows Multiprocessor and give three driver files Hal.dll
ntkrnlpa.exe and ntoskrnl.exe. So it lookes like the Hyperthreading is
working fine. I was hoping I would not have to do a Repair Install. thanks
for the help.
