Hard time getting machine to start

[taije]

I recently (1 month ago) built my first PC. It ran great for a month. couple of days ago I needed some files from my old machine and didn't have a monitor, so I borrowed on from the new set-up. I restared the new machine with only one monitor and it fired up until windows started and then shut down. I got it to start in safe mode and then switched over. It restarted fine after it was warm. Then I shut it down for the night and in the morning the problem was there again. I have cleared the CMOS and reset it. Problem is still there. Now the only way to get it to start is to boot into bios first and then go from there. Is this a power supply problem or something dreadful?

System consists of -

Biostar m7ncg pro mobo (dual VGA onboard)
Pow Max 400W single fan AMD/P4 power supply
Athlon 2600
Maxtor 80Gig HD
1 gig DDR400 RAM
floppy drive
CD-ROM
CD-RW

and numerous peripherals

Please Help

Have you tried the diagnostic start up ????

Two things to consider, heat and the dual on board VGA.
Oh and reinstalling windows

First of I would eliminate the HD possibility by puting in an old PCI card or AGP card or something to make sure its the the dual on board vid set up (doubt it but you never know).
Then I would look into other cards you have in there.

Like I said I really doubt that there is a HD problem but you never know.
Now when you say that you get into windows and it shuts down do you mean it completely loads windows and all start up programs.
If so then one of those might be the culprit.
If that is the case you should hold down shift while windows is starting up. This should stop any programs from starting up. if that happens you can start to eliminate each program that suppose to load by starting them up manualy.
You can get a list of them by going into MSCONFIG and you can stop certain ones from loading over there.

Right now it is starting fine because it is warm.

When I say that it shuts down going into windows - I mean that windows only begins to load. Sometimes I can't even get into the bios until I have tried a few times and it warms up a little

Hi folks -

Thanx for your help - I bought a new power supply as that I figured that was the place to start - That fixed it .
