Compaq Presario SR2150NX won't boot

Posted on 2008-06-25
Last Modified: 2012-08-13
I have a Compaq Presario SR2150NX that all of the sudden won't boot up.  I get a steady green light from the PSU and the light on the front of the PC will come on.  There is one short beep and the fan spins for a second but then stops.  

I've tried unplugging everything from the back and disconnecting the CD drive, hard drive and ram as well as pulling all the cards.  I also tried to drain the power by holding in the button while the pc was unplugged.  HP tech support was useless.  Told me I could get it serviced for $50 more than it would cost to buy new.  

Anyone have any ideas as to how I can troubleshoot this?

Hmmmm... Don't suppose you have any spare parts laying about? A spare PSU maybe? My first thought would be the system board or PSU, but it's hard to test if you don't have either another PC to try bits in, or another PC to take bits out of to try in the faulty PC! :)

If you've tried booting with ALL removeable components taken out (bar the system board and PSU of course) and you're still getting nothing whatsoever (not even BIOS info) then 1 of those 2 must be where the fault is.

Figuring out which one is going to be virtually impossible without having say another PSU to try...

Also check the motherboard for leaking or bulging capacitors.
I would also suspect the PSU, as long as the 5v standby power is present on startup the motherboard will attempt to start in this fashion. Once it starts, it uses the +12v rail to run the components in the system, and this may be bad in the PSU or on the motherboard if the capacitors have been blown.

I think I actually have another PSU.  (My father's emachines PC went and I tried replacing the PSU but I guess when the PSU goes on those they take the MB with them)  I can try that one to see if it fits and fixes the problem.

I saw that badcaps site on another post.  I will take a look at them tonight.  

Thanks, I thought I was at a dead end.

OK, I put the new PSU in but it has only IDE connectors and the hard drive is SATA.  Anyone know how I can convert an IDE cable to power a SATA hard drive?

OK, so I connected the new power supply and now I get to where the screen flashes the Compaq logo  with the "hite esc, F8... options, but it freezes there and I am unable to get any further or get to the boot menu.  There are also a few lines across the screen.  The top one is green and there are three others that have blocks of white with bluish red boxes in between them.

If this should be counted as a seperate thread please let me know and I will award points and post a new thread.

Thanks again for all the help.
