First return to some basic electrical principles. A power supply
can be defective or undersized; computer still boots fine. A failure
is not apparent until system draws major power. For example, video
card may not draw a maximum load until many internal functions are
being activated. Only then suffer from low voltage. Low enough to
work fine (according to Device Manager) but maybe so low as to cause a
function (or memory location) to fail.
No way to determine a power supply sufficient without actual
numbers. That means operating the system under a maximum load, and
then collecting important numbers with a 3.5 digit multimeter. The
entire procedure is posted in "When your computer dies without
warning....." starting 6 Feb 2007 in the newsgroup alt.windows-xp

In your case, the useful part is a latter paragraph for voltages on
purple, yellow, orange and red wires when system is fully loaded.
Then post those numbers here to learn other facts about your system's
integrity. Numbers mean those with better technical knowledge can
provide useful replies.
Fully loaded means accessing disk drive constantly while displaying
complex graphics (ie a movie), using sound card, accessing internet,
reading a CD-Rom, etc all simultaneously (multitasking). Only then
does a simple tool - the multimeter - take useful numbers.
Nothing else including speculation from the tech shop can report a
power supply sufficient. Especially when so many computer experts do
not know how electricity works and power supply manufacturers take
advantage of that ignorance by claiming misleading numbers.
Let's say your video card has a soft memory location. What does the
comprehensive hardware diagnostic report for that video card? Better
manufacturers provide comprehensive diagnostics just for your
problem. Device Manager can only report the most obscene failures.
One soft memory location would be ignored by Device Manager. But a
diagnostic operating first at room temperature, and then repeated at a
'pig heaven happy' temperature created by a hairdryer on highest
heat; that diagnostic would either locate a defect or would be the
only indicator of a good video controller.
Notice this post is about getting a definitive answer. Your tech
shop, for example, could only speculate an answer. Nothing previously
posted even says the power supply is functional. A defective or
undersized power supply can still boot a computer just fine. That
problem can only be identified from numbers as detailed above.
