You don't need a BIOS upgrade. Once the OS is loaded, then
OS replaces the BIOS anyway. You have received many wild
speculations about "try this and try that". If your auto
mechanic worked that way, you would call it a scam. Those who
don't first learn will wildly assume the problem is only what
they understand. Its called wild speculation.
Before trying to fix anything, one must first collect facts
- especially the numbers. If you don't understand what those
facts are saying, then post it for additional help. But do
not try to fix anything until the problem is identified.
There is no reason to shotgun a computer.
Some basic facts you should already have. What does Device
Manager report? What historical information (ie reason for
sudden shutdown) is in Event (system) Log - which may have
been destroyed if you erroneously reloaded Windows. Where to
find these information sources? See Windows HELP if you do
not know what they are.
All responsible computer manufacturers provide a complete
set of comprehensive hardware diagnostics either with their
machine or for free on the web site. What do those hardware
diagnostics report? IOW break the analysis down into parts
AND then test those individual parts. Hardware diagnostics
test hardware without any complications from Windows.
Is the problem in a power supply? One requires a few
essential tools - a screw driver and a 3.5 digit multimeter.
One first determines with that so inexpensive meter whether
power supply is good or failing long before even considering a
PSU replacement. The procedures posted previously: "Computer

Again, responsible repairman don't shotgun. Takes more time
and wastes good money swapping power supplies only on a whim.
Its called working smarter - not harder.
