Only 1 core working?

[P1Fanatic]

Troubleshooting why Crysis is a tad laggy and ran cpu-z to find that its only running 1 core. Its been running 2 cores fine since last reinstall of win xp.

Any ideas how I get the 2nd core working or at least test if its died on me?

Cheers,
Simon

Go to

Start>All Programs>Accessories>Command Prompt

and then type: bcdedit /set numproc 2 (assuming dual core, lol)

Is that under vista as Im running xp pro 32bit and that command doesnt work?

Open a command window and type bcdedit/? see if it works and check the options you have. Not sure about XP, I cant check, only have a Vista laptop at the mo.

or another way Start->run->msconfig->boot, press advanced options, check /NUMPROC= and choose how many cores. All it does is edit the boot.ini

If I try that the only option is 1 so its a case of it not being recognised. Bios recognises it as dual core but in system -> device mgr only one processor listed.

Even if windows doesnt pick it up cpu-z should. Im thinking maybe 1 core has died on me but have no way to prove / disprove this other than plugging in another pc which I dont have access to currently.

Maybe my pc is telling me to upgrade to Intel

You can use the NUMPROC line to completely disable cores as far as Windows is concerned. Try editing the boot.ini directly.
