installed antec earthwatts 500w, now my pc not working?

[guynexdoor]

I installed a new PSU, and now my PC gets stuck at the windows xp loading screen....

I have 2 HDD, and I disconnected one of them, thinking it may be causing problems.

The keyboard light on the keyboard isn't on either during this screen.

I tried to start in safe mode, and it hangs. Did I damage my mobo?

I upgraded from a 350w to a 500w.

What is causing this?

 

[guynexdoor]

I was reading in other forums that psu's sometimes have cables that say "fan only"

But the antec doesn't have anything like that. Is it possible that my optical drives are not getting enough power? I'm trying to boot to the CD, and it doesn't even do that!

I'm gonna boot to cd, and do a repaid on xp.

When you say "stuck", where does it stick? Is it when it fades from black, when you start seeing Windows XP, but only faintly? THis is before the Windows XP logo comes up fully and you see the animated loading bar going from left to right?

I've had similar issues recently, but my computer has been stable running Antec EW500 for a couple of months now. It happens about 5% of the start up, and it has me concerned. I didn't think it was a PSU issue until you mentioned it. I think it's somehow HDD not working right.

The loading bar is where it gets stuck. The bar moves like it's loading, but nothing happens.
The bar keeps moving, it doesn't freeze. It just doesn't get to windows all the way.

I'm doing a xp repair right now from the boot cd.

Why don't you put the old 350W PSU in, to eliminate, or confirm the new PSU problem...?

If the PSU is the problem, you will completely destroy your XP installation with that Repair.

 

[guynexdoor]

I did the repair. I'm back and running....

weird.

 

[PianoMan]

Yup - weird. Gremlins are alive and well.

If now the computer works, what DID Windows repair? Double weird.

Good to hear it's up an running!

 

[guynexdoor]

The Windows Repair worked...for a few days. Until it started to automatically d/l stuff via msoft update....
I think doing a windows repair rolls back some SP updates...

So once it started re downloading stuff, it caused some problems and I was back to a non booting PC.

I just reformatted everything, and it works fine now. And I turn off automatic d/ls and I go to internet explorer and manually d/l and install them. I think the problem came from the computer asking me to install updates before it turns off, and I think it fails when I did this.

Something is not right with that PSU...

 

[guynexdoor]

As of right now, everything is working.

There was one other time that it didn't boot, but I hit restart button, and it went without a problem. How does a PSU prohibit a PC from starting up. I don't get it.

 

[guynexdoor]

CORRECTION!

It's doing it again! It's not booting! I turned on my PC, and the first bad sign was the monitor just stayed "black" Monitor was on, but it wasn't displaying anything. I hit the reset button and now it is stuck at the windows loading screen, the blue bar just keeps going and going.

Is this a bad antec PSU?

 

[JustaGeek]

Remove all excess hardware, and install your old 250W PSU.

Unless you can find another PSU.

If it happened right after you've replaced the PSU, this would be the most obvious culprit...

 

[guynexdoor]

I did as you said. I'm getting the same problem. I try to boot in safe mode, and it locks up at the mup.sys driver.

Could I have damaged my mobo upon installation of new PSU? IT WAS working before....
The last thing I installed was my printer, but I've been using the same printer.

Possibly. Handling computer components will always have the risk of damaging it. That risk is very small - heck I've abused stuff and had them still work, however the risk is real. I know someone BITD with a Geforce 3 Ti video card that stopped working after being removed from the computer and handled.

I also know someone in RL who broke a surface mount resistor off his 6800GT just yesterday when he was handling the card. His thread's here. "I had swapped everything from my old case into the new case and it was going quite well, until somehow I knocked off a tiny surface-mount chip from my BFG 6800 GT."

You might have corrupted the XP during the Repair Install with the bad PSU.

I would get a reliable PSU and do the Repair Install again.

 

[guynexdoor]

I isolated the problem...

I have the old PSU and everything is fine. However, when I connect 2 optical drives, it gives me the boot up problem. In fact, it's only when I plug in the DVD player that it gives me problems. Can a bad optical drive cause such issues? So for now, I am have only one optical drive plugged in.

Maybe you have a bad IDE/SATA cable. I'd try a different cable and verify it. Also if it's a IDE cable, make sure your double checking the jumper on the back of the drive to see if it's set a Master or Slave. If you have 2 drives on Master or Slave then maybe your getting a conflict there. Don't know for sure, but is something to checkout. Also if its a SATA connection, I'd check with a different cable and put into a different slot on the mobo, just to try and rule out that possibilities.

 

[guynexdoor]

I haven't isolated the actual IDE cable. I shall try that.

It's just weird cause it was working before. All of it was fine...until I put in the antec PSU.
I know that it's not the jumpers b/c I didn't move any of the drives, or jumpers.

Can the actual drive be bad, and perhaps it was damaged during the change of PSU?

 

[Lunyone]

Yes it's possible, but unlikely. I wouldn't rule anything out. Borrow a friends DVD/CD and see if that changes things, especially if you change out the IDE cable first and don't get any change.
