Cut out after start up

I've recently upgraded my memory from 192Mb to 512Mb (old
memory removed). Now when I start up Windows loads, the
desktop appears and I can start any program, but about 5
min after start up the computer cuts out then immediately
restarts itself but, because it wasn't shut down properly,
goes through the scan disc routine, re loads Windows and
off we go again without any more problems and the computer
will work OK. Has anybody any idea why the first shut down
occurs ? Grateful for any help, it's driving me mad.

Spontaneous restarts are usually due to heat (dirt clogging up cooling fins on
heat sinks, fans not operating properly, air pathways obstructed), or to
improper seating of components, corrosion of contacts, etc., or a simply faulty
component.

The most obvious possibilities in your case are dirt or corrosion in RAM
sockets, or not being fully seated (warming up after starting causes the
contacts to move in relation to one another--or, most likely of all, you got BAD
RAM. Not uncommon to have RAM go bad right out of the box, especially with the
type of error you report. Open up the case, check around for anything you might
have dislodged during your last visit, pull the RAM, make sure RAM and socket
are clean, check CPU and any other heat sinks/fans for dirt, put it all back
together, and if that doesn't affect the problem, ask for warranty replacement
on your RAM.

"Out of Memory" Error Messages with Large Amounts of RAM Installed

(1) "START, Run, MSConfig, System.ini tab, [vcache] section".
Don't just open the section; click it to highlight.
(2) Click the "New" button
(3) Type in: "MaxFileCache=524288"
(4) Click "Apply" and "OK". Reboot.

JUST, don't exceed usable RAM, as seen at "START, Run, MSInfo32"...
376MB RAM, it says for me, because Video has grabbed away 8 MB.
