Cpu Freezes at windows sign on

Is it overclocked? What CPU is it? What motherboard?
Steps to take if it's non overclocked:
1. Reinsert the CPU
2. Check for bent pins in the socket
3. Enter BIOS of you can, and check the heat and cpu speed
======================
Overclocked steps to take:
1. Go to stock clock
2. Set all voltage levels to the default
3. Restart?

You could also try to start in Safe Mode (press F8 during startup), just to see, what happens.

The computer is a HP 8674D with win 98.

May want to make sure there are no cords or wires stuck in your CPU fan. If they get in there your fan won't run and your cpu will shutdown.

My advice, Just get rid of it and buy a new pc

Correction, if it doesn't shutdown then it isn't a wire.

Sounds like overheating CPU to me. Can also be memory.

I've had freezing issues (just around windows login or even as soon as POST) because of both of these issues.

Easier one to test is the RAM. If you only have one stick, move it to another slot and see if it freezes.

If you have more than one stick, take one out, see what happens, if it still freezes, take the other out and replace it with the later and/or try moving them to different slots. (trial and error)

If it functions with either or both sticks in all slots, then it may be your CPU overheating.

Here's a thread that may help. Its from techspot, someone else had the same issue. It didn't fix it, but have a look:

Thanks to everyone for the help! I am still working on it. This is a project computer. I have an up todate one to use.

Sure, may want to investigate why you can't type your user name at login or you why you can or can't type f8 to enter bios
