Hi, im sure this has been discussed before...i just cant find it on the forums. But, can someone give me detailed instructions on how to turn on or off my hyperthreading? Please just dont say to GO to your bios...i dont know what that is. Sorry, and thanksWhen you first turn on the MACHINE, before the Windows logo you should see a key combination to get to setup. That is where you must go.

What computer make/model or motherboard do you have?my computer is a pentium IV, 2.8 ghz processor. It has about 512 mb of RAM and about 115gb of harddrive space. Its VAIO, and for my computer...it doesnt do anything before the windows logo pops up,(i have XP btw) all it shows is a SONY logo, a PENTIUM IV logo, and blacks out a couple times, then the Windows loading logo. soooo yea...hope you can helpWhy do you want to turn off hyper THREADING?

Why do you think it is the cause of your problems?

Remember: If hyper threading froze PCs, it wouldn't have been sold in stores.

Look for the problem elsewhere, young one!
i dont want to turn OFF my hyperthreading, i dont think its ON! so that is why i want to make sure and try to access my bios.Look in the manual for bios access. F1 or delete key when you see the Sony logo perhaps?With a Sony Vaio you should USE the F3 key to enter the BIOS BIOS KEY CODES

If there is the option to turn HyperThreading on and off you are in luck. Sometimes it is necessary to re-install XP if you take a look at Google.

Dual Processing is a better option, if you want an engineering opinion.
