Won't Boot Up - No Beep or Display

October 26, 2010 at 19:00:24
Specs: Windows XP Home, 3.0E GHz/ 1GB pC3200 DDR SDRAM
I tried to burn a DVD and it failed, at the same time my computer froze with the burn error still on the screen. So I had to hit the power button to shut it off. I tried to restart it wouldn't boot up... the fans all come on, and the lights on the HDD come on and stay on, but nothing else. The cd drives don't even try to read a disk when I put one in.

I've tested the psu w/ a multimeter and got 11.98v on the yellows, the 5v tested good and the 3.3v's tested good also. I've tried a different cpu and still no boot up. I took out the CMOS battery and reinstalled it, hoping to reset that and that it would help, but no dice. Any advice is appreciated greatly, thanks in advance.

HP Pavilion a566n - 3.0Ghz P4 - 1GB DDR SDRAM - Integrated Intel Etreme Graphics 2 - it says p4SD-LA on the motherboard annnnd that's all I know about this system. TIA.

Disconnect the power & data cables from the CD Burner.

I have seen it happen that a faulty CD drive prevents a system getting through the POST. It is purely a guess but I think your burner has failed. Windows had just enough time to detect the burn error before it locked up.

If that does not help then disconnect the cables from other drives and take out any PCI cards. It is a process of elimination.

Thank you very much, Richard59.

I disconnected the power and data cables going to the DVD and CD drive... no such luck. I then disconnected the multi-card reader, nothing. Then the HDD, nothing different. I took out the RAID card (I think that's what it is, it has an ethernet port and goes in one of the expansion slots... nothing different.

Finally, I removed both sticks of RAM, and this caused a constant beep that lasted at least 20 seconds non-stop before I finally shut it down. I'll have to search what that means.

Any other suggestions as to how I could pinpoint what I need to replace would be greatly appreciated. Thank you, take care!

I'm just submitting a results report, just in case anyone else experiences a similar situation.

Well, I finally tried putting in an old HDD that had crashed (hoping to get my kids pics off it someday), because when it went out the machine still would semi-boot up... and out of desperation.

When I plugged it back into the wall though, I smelled that burnt electrical smell coming from the power supply unit. Sooo, even though I'd tested it w/ a multimeter and even though it tested within the proper ranges, it was going bad after all. HTH, take care.

Thanks again, Iroc-Z... it was indeed the hdd. Wish I had read this article before buying a Seagate Barracuda 7200.11, but glad you helped me get it figured out!
