and a dell custom PSU for just this mobo and its odd duck jack. (called PICO plug)

Question posted in 2014, almost 5 years back, laptop by this time seems to be abandoned or scrapped? and if still searching only solution is to change the Hard Disk Drive

It seems you have a problem with your Processor regulator that is why your computer sending an amber message.
This problem always happens to Dell Optiplex mostly and there is no solution for this except replacing your Motherboard.
To verify this problem unplug yellow (2 yellow and 2 black cables) cables near the processor and then try to turn it on when you see the fan processor can run smoothly and the power light getting green that is the sign that your processor regulator having some sort of problem.

Hope this will answer your problem

That GX280 is today 14 years old and came new with XP right>
still stuck at XP? if yes, doom is all there is.
XP is (as you learned) a huge virus magnet.(worse every day)
some were built with windows 2000, win2k, hopeless extreme...
windows xp recovery or restore fails because sure the recover software is corrupted and infected too, so erasing HDD is the only path as your discovered. (page 30 in your manual at dell will fail)
but not the dell disk install same page.
BTW , ive never seen an XP PC not infected, ever..... so..... bingo.
ever google.?
older post but and others will find this useful.
There are many pitfalls to OS installs I will bullet them.

  • The HDD is bad, (but if only infected it will be erased first)
  • Your PC has OEM COA license from Dell for MS windows.
  • Using most Microsoft install media will fail using your COA.
  • W7 will fail, W10 used to work this way but not now.
  • You failed to buy your DELL windows media kit long ago so is lost or gone or, never bought.
  • that means you have 2 choices, buy new windows 7 or 10 or run linux, I am sure you will not wont to run free linux. Ubuntu v17
  • SO buy windows 10-32b, (say) from and install it.
  • During the install , pick custom or advance setup and delete all partitions. click CUSTOM now. see links below.
  • then do as it says here.
  • then do the full install, as documented at microsoft dot com.
  • end story but not all pit falls,
  • Pit fall 1 is HDD is bad, fails Crystaldiskinfo , app.
  • or fails Linux demo boot, run disktests and fails.
  • on dead pc, I run this.
  • if the C6 (198.) is not ZERO, the HDD IS NO GOOD AT ALL.
  • All drives (most) end up like this, runs but has no spare sectors left and can no longer self heal itself, and is a bad HDD.
  • Better is to upgrade to SSD, for sure , you will never go back to HDD ever again I promise.!!!
