OK...how about an old [maybe not that old] computer problem? I am
prepping a Compaq Presario 5000 [700 MHz, 256Mb RAM, Win2K Pro] for my
son-in-law. Everything runs good, all loaded with all the needed Win2K
updates, Office 2K, IE/OE6, etc]...but it has a problem!! After about an
hour using the Internet, it freezes...no Mouse, no Keyboard, no response
at all...last screen fully visible, PC fans and power supply still
running. Strangely, it is apparently NOT a thermal/time problem as it
can sit for hours downloading Internet updates, but only seems to happen
with changing screens, pages, clicking links, etc. The only problem that
I seem to have noted is that a lot of the PC functions are using the
same IRQ11 [a problem?]. Any ideas on what to look for and how to
identify the problem? TIA...John

How old is the hard drive? It might be wise to do a surface test if you
have the software to do it. RAM is another suspect. Try removing the
sticks and cleaning the contacts with a pencil eraser or alcohol.

See if the problem persists using a different browser, for
example Firefox if it was using IE or vice-versa.

Try updating the video driver, get it from the respective
chipset manufacturer instead of Compaq.

That doesn't necessarily mean anything, downloading internet
updates doesn't take as much processing power as playing
many of today's scripted or Flash enabled webpages.
However, if no fans have failed, the system is not clogged
with dust, and operated in a typical climate controlled
room, there is no reason to think that now suddenly it would
start overheating - unless it had poor heatsink grease that
degraded drastically over time. If all else fails, pop the
CPU 'sink off, clean off original thermal interface material
and put a fresh clean coat of (whatever, even generic
silicon grease would suffice for a 700MHz CPU). If it is a
slotted type CPU with a cartridge instead of socketed, leave
it alone it is not likely to have this problem from the
factory build and thermal interface.

That's not likely to be the problem. Examine the
motherboard around the CPU socket region for failed
capacitors (domed tops or leaky residue on tops or bottoms)
and likewise in the PSU (after leaving it unplugged from AC
for a few minutes). If you have a spare PSU, try it.

Also check Windows Event Viewer, and if nothing else seems
the problem, run the hard drive manufacturer's diagnostics
and inspect the open system's cards, cables, etc.

I would place odds on it being the PSU, but other faults are
possible.

Where did you get the video drivers? If you're answer is Microsoft (or
Win2K just recognized my card) or Compaq/HP, go and get the drivers from
the card manufacturer. If you're using onboard video, use the drivers
from the motherboard manufacturer.

This is only one possibly thing that could have gone wrong, but it's
easy enough to try, and I've seen it fix that exact problem before.

You could test the processor and memory with Prime95. When prompted to
"Join GIMPs" or "Torture Test", select the Torture Test option. You
can stop and quit the program, if no errors are detected in a
few hours of usage. The program stops on the first error it finds,
and if it stops rather quickly (couple minutes), then you'd suspect
a processor or memory problem.

http://www.mersenne.org/gimps/p95v255a.zip

256MB seems a relatively small amount of memory. I have
Win2K on a machine with 1GB of memory, and at bootup,
Task Manager shows 260MB in use. (With an AV program
running in the background.) I expect with a smaller
amount of memory available, Win2K won't be quite as
wasteful.

You could leave Task Manager open, while surfing the
Internet, and see what the free memory looks like
as time passes.

Some motherboards that use Slot 1 processor modules,
have a problem with the connector. Sometimes, pulling
the processor and reseating it, then securing the
processor in place, will provide temporary relief.
You can try that, and see if it runs better for a
few days.

For a video card test, you could try the demo loop on
3DMark2001SE. But with 256MB of memory available, I
don't know if that would load OK or not. If Prime95 is
passing, I'd want to find something to load up the
video card, and see how sensitive it is to a workout.

There are some older video card benchmarks, but they don't
sustain a test for very long, and I don't think they can be
set in a loop.

When a computer appears to freeze, one test you can do,
is try pinging it from a second computer. You can use
"ping <ip_address>" from a DOS window (command prompt),
to see if the frozen computer is really frozen. If the
machine answers a ping, then you know the processor
is in fact still running. That may tell you the problem
is just with the video, and a frozen display subsystem.
