Specs: window xp, 512/1.00
A customer brought ibm thinkpad R40 to me for repair. I troubleshoot and I found out that the restart when it boot to desktop and it freez too. I open the system and I apply thermal gel on the processor and I close back. Yet the laptop still restart and freez, but the cooling fan is working fine. What can I do.

Are you an experienced repair person? Why would you assume "thermal gel" is the problem? Did you check the temperature & find the CPU to be overheating before you opened the laptop & applied the "gel"? It may simply be a software/driver issue or an infection that's causing the system to lock up. Can you boot into Safe Mode without any problems? Did you try running System Restore? Did you try booting off a Linux disc to see the system still locks up when not accessing the HDD? Did you run a HDD diagnostic or test the RAM with memtest86? In other words, there are many things you could have tried before applying new "gel".

I trust you removed the thermal compound and then applied it in the way approved for that particular CPU. If you depart from the correct procedure it can produce issues. There are several methods but you have to choose the correct one.

As given, boot to a live Linux CD or flash drive. If it works there you will at least prove whether or not it's a Windows issue.

OK, if it freezes in BIOS then you can at least forget software, which I guess is why you posted this on the hardware forum.

There are all manner of possible reasons but one simple thing I would try first is to take out the RAM stick(s) and clean it(their) edge connectors with a soft pencil eraser. Pop them in and out a few times to clear any oxide on the sockets. Check all connections for firmness while you are in there, including those for the HD.

Always pop back and let us know the outcome - thanks
