Trouble With Start Up

[Curiosity_Strikes]

Gateway DX4300-11 Windows 7 Home Premium

Took a power hit and I'm not sure what all happened. System would not boot at all initially. Then, sometimes it would start when the power button was pressed but would only get to the POST screen, no further. Most of the time it would do nothing at all. Once or twice it would boot to the desktop. Nothing was consistent.

After some trial and error and a PSU swap, this is where I am:

Pressing the power button will start it, but it stops at the POST screen. Pressing any key does nothing including Del to enter SetUp or F12 for Boot Order.

It seems like I can hear disk activity, but I can't be sure.

Pressing the power button a second time will usually cause the machine to reboot at which time it goes to the desktop normally. From there I have full use including network, device and program installation, etc. Onboard LAN port is dead from the power hit. Installed a USB wireless LAN device and it works fine.

Questions:

Why won't it start normally on the first power button press?

Why will it start normally on the second press?

How do I correct this?

if you already replaced the psu and the issue is still happening then it could be the motherboard, have you tried resetting the Bios and the CMOS

Why won't it start normally on the first power button press? If it is starting normally and loading to OS after second attempt and maintaining power then it is most likely not you’re PSU, but would lead to your motherboard

Why will it start normally on the second press? That is odd, Does it start for sure the second press every time? Once again this could be an issue with the Motherboard.

How do I correct this? At this point from the information that I have I would think that it is your CMOS battery on your motherboard.
You can reset it, but may have to get a new one. I have listed Directions below on how to do this:


Try to reset the CMOS. Do this:

You will need a paperclip/screwdriver/some metallic stuff for this. Also a flashlight is welcome (or just do it with day light):

1st-> open PC.
2nd -> search the CLR_CMOS pins. should be something like this:



3rd -> touch both pins with the metallic (something that is conductive) stuff, so it short circuits, for 5 seconds at least.
4th -> BIOS should be reset to factory default.
5yh -> yey

^^ I'm little more than a tinkerer, not a tech. No, I have not pulled the CMOS battery or changed anything in BIOS. I have been in BIOS to look around and didn't see anything that stood out as unusual. I think I remember seeing something about resetting to default, but I'm not sure what that does or if it would make things worse in any way.

At this point, it seems to. Not sure if that will change.

Is that with the CMOS battery in place? Unit powered up or not?

4th -> BIOS should be reset to factory default.
5yh -> yey

Checking on that.

...........

OK.

Turned PSU off.
Pulled the CMOS battery.
Swapped jumper positions over.
Pressed/held power button for 10 count.
Swapped jumper back.
Inserted CMOS battery.
Turned PSU on.
Pressed power button.
Booted to POST, one beep, two beeps.
Booted to BIOS screen showing the reset, time not set, etc.
Set Time and checked a few other things.
Save/Exit.
Self booted to desktop.

That's where I am now. Anything else to check before trying a restart?

 

[Curiosity_Strikes]

Used Start button, Restart

Booted to POST screen and stopped.
Pressed case power button; rebooted and proceeded to desktop properly.

So, no change.
