1) Have a eMachine T6426 with XP Pro. Whenever I try to reboot, it freezes. Have to hold the power button in. Any help out there?

Separate problem, possibly:
2) When power up - sometimes - fans rev but the OS doesn't kick in. Other times the machine boots up properly after I push the power button to turn it on.

Emachines are known for 2 things, Bad Power supplys and weak motherboards. Either one can cause your problems. I would look into the power options and have everything set to never and see what happens. Sometimes when you have 2 separate hybernate or standby's running it can cause this problem. by separate ones i mean windows and bios both have them running. Shutting them off in the bios could fix the problem. I wouls also download speed fan and use it to check the voltages the motherboard see's. Low voltages ( 11.7 or less on the 12volt line, 4.5 volts or less on the 5 volt line) can cause real problems.

Thanks for replying! The machine will shutdown elegantly. However, it won't reboot without freezing.
How do I check power setting in the BIOS?

You don't. eMachines rarely provide them in the BIOS, it'll probably tell you the CPU fan is spinning and that's it.
You would need a utility such as Everest or Speedfan to give you the voltages of the power supply.
