Hi,

I have a new problem I can't figure out on my HP d4100y PC
(Win XP SP3, 3GB RAM). I have not seen this problem under these
circumstances elsewhere in the forum, so here goes:

When I start it, particularly in the morning, the lights will come on
and it still start to boot up -- then suddenly the power goes off, and
it tries to start up again, and again, and again. The fans turn on,
the DVD-RW lights comes on, the drive is accessed, and this will
happen over and over.

Then after a few minutes usually, maybe because something warms
up enough or for whatever reason, it succeeds in loading Windows.
Sometimes the "We apologize for the Inconvenience" screen comes
up, other times it loads up fine without it. There are no errors shown
like this or that file is corrupt or missing.

I have checked it thoroughly for a virus and found none, I have run
CHKDSK /F /R and found nothing wrong, and I have changed the CMOS
battery for another unrelated (or who knows) problem a while ago and
I get this every day. Also the machine is not set to restart itself in case of
a power outage, and I've also tried changing the boot order so it will try
to boot from the HD first instead of the DVD -- but that didn't change
anything.

Thing is, once everything is up and running, I can restart the machine
a hundred times and it never creates any trouble.

I imagine the simplest answer is "bad power supply" but I have a feeling
that is not it -- that was replaced about a year and half ago.

Can anyone please help me get through this headache??

Thanks :thumbsup:

I would (temporarily) try a different power supply and see what happens.

Hardware can fail anytime...there is no timetable for such in the scheme of life. New components are bought every day which arrive DOA.

Well, it's certainly possible for the PSU to fail...

It currently uses a 400 watt box...any recommendations for a good
replacement? :thumbsup:

I tend to find that Ultra power supplies (www.tigerdirect.com) have my trust (based on experience)...but there are any number of PSUs that do the job adequately.

IMO, choosing a PSU kind of depends on what's part of the system and what the prior PSU was...and how it performed. If I had problems from the start (I've never had this), then I might assume that the previous PSU may not have been adequate for my current system demands.

You won't find an objective guide anywhere and every person will have different opinions on how to choose one.

Initially, I used to buy the most inexpensive ones which were at least 300 watts...those all worked well for the systems I had then. I'm now a few years older (regarding such) and just tend to go with Ultra PSUs, based on price and experience.

I find that 500-watt PSUs are adequate for what I do and I've had up to 8 hard drives attached to the system at various times...with no problems. I don't game so I don't have a video card that requires a lot of power.

IMO, it's foolish to try to recommend a PSU for a system I know nothing about...so I won't do that. Providing you with my perspective is about all I can do :thumbsup:.
