Freezing Computer / Network Disconnect

I have Windows 2000 NT

My computer freezez on the spot. So far, only when I'm in the process of doing something: Opening Internet Explorer, or another browser, Opening Outlook Express, Clicking on a shockwave flash thing, clicking on a file in winamp. The screen freezes, I loose all control from mouse and keyboard, Control Alt Delete doesn't work, nor does escape, or any random key I happen to press. I've tried leaving the computer alone for a while and coming back to it, finding it still to be frozen. I end up Rebooting every time.

When I reboot, the computer scans both of my disk drives, and once windows starts, it does not detect my network connection. (I am connected to a router hooked up to a cable modem.) I then reboot once more and my internet connection is back.

I've scanned my disk for viruses and spyware, i have the latest definition files and windows updates... what do I do now?

EC, Some Things To Do...

First, because the freezing problem could be related to "heat" issues, remove the cover of the computer and use some canned air to blow out the dust and junk from the fans and motherboard. Point a housefan at the computer inards and run the computer that way for a while..Does it help?

What size power supply do you have and what type of hardware is installed? If you're like most, you have lots of RAM, a couple of CD drives, a big hard drive and a fast processor......with a little tiny power supply. A new, larger power supply, in the 400 watt range can usually help.

Have you installed the later drivers for video, audio, etc.?

Next, install the "msconfig.exe" file from a Windows XP computer using the instructions in the link below:

After that, follow the procedures in BOTH of the links below to shut down unnecessary start up programs and unnecessary files that might be causing conflicts on the computer:

CNET Computer Cleanup Links
For Windows 2000/XP, ignore the first couple of sentences about checking "resources" in the link below but follow the rest of the procedures including the "Services" links at the bottom.

How To Shut Down Unnecessary Start Up Programs

How To Clean Unwanted Files From The Hard Drive

After following all the procedures above, run Error Checking/Chkdsk and Defrag to optimize the hard drive:

Hope this helps.

In addition to Grif's excellent advice, while you have the case opened, do a visual inspection of the mainboard. Specifically look for physical signs of damage, burns, bulging or domed top capacitors. I'm experiencing the same problems with a machine and it appears that the capacitors are failing.
Best of Luck
