It happens when I turn my PC on, it make problems on the first
3-5 minutes. Like, it gets stuck when loading windows, or reboots
without a reason. I reinstalled windows, but same problems again.
What could it be ?

Sounds like Hardware. Perhaps the Mother Board. Fortunately, they're not
expensive these days.

Before tossing the motherboard I'd recommend checking out the power
supply (in other words, replacing it), and possibly a BIOS upgrade as
well.

It's ASUS A7V266-C Motherboard, pretty old one. Why do you think I need
BIOS update, it worked fine until now.

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
doesnt start at all" in   alt.comp.hardware on 10 Jan 2004

   http://tinyurl.com/2t69q   and
"I think my power supply is dead"  in alt.comp.hardware  on 5
Feb 2004 at
   http://www.tinyurl.com/2musa

  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.

I suggested a BIOS upgrade for a specific reason -- I've had two
customers who had Windows suddenly start crashing within the last couple
weeks, in one case the same applied after he reinstalled and patched
Windows -- It looks like the old BIOS versions on their motherboards
(Both Gigabyte, IIRC) don't play nice with one of the recently released
(Windows Update supplied) drivers.

I had the same problem.  The power supply fan was stuck on the shroud.
After freeing it, all is well.

I agree, most likely the 5 volt rail is not stable. try another PSU first.

PSU ?

PSU is but one component of a power supply 'system' - as
cited in those two previous discussions.  Failure could be due
to lots of things. PSU.  Motherboard. Power supply
controller.  We could wildly replace parts until the entire
computer (except chassis) is replaced.  Don't waste time.
What looks so complex is the simplest method of identifying a
problem quickly.  It may take one hour to read and less than
two minutes to get the numbers this time and every time in the
future.  Why the numbers?  No one can do anything but
speculate if you don't provide those all so important
numbers.  Only with those numbers can those with education
properly help you.

  Again, don't wildly fix something without up front facts.
Posted was speculation blaming PSU, BIOS, or motherboard.
Let's add a few more.  Disk drive power problem.  CPU.  CPU
voltage regulator.  Screws attaching motherboard to chassis.
Intermittent power cable.  Defective power switch.  Marginal
memory.  Stuck fan.  Then we have the classic myths - too much
dust.  Spikes from the power line.  Will you replace and fix
all these?  Or will you take but two minutes to get the
numbers?

Could be a problem with your memory or motherboard.
Do yuo get a blue screen when it reboots?
