Hi, I have this 873n that I have been trying to repair and it is not working. I have tried everything I can think of and I can't figure it out so I thought I would try here. Just so you know, I am very experienced and have tried known good parts.
I got the computer and it was locking up during bootup. It passes post but freezes during windows boot/splash screen. I tried using the destructive restore and it seemed to go fine until I got to the part where you enter language, time zone, and stuff and when it got there, it went into super slow turtle mode so I ended up quitting on it because it locked up and took forever( over an hour) to get off one page! So then I thought I would try restoring it with a factory xp pro copy instead of the HP media center restore. I only formated the main partition and left the recovery partition in tact but I heard I killed that because formatting the regular partition you loose the msinst folder or something like that but no biggie because I have a retail version of xp pro to use if I can get it to work. I changed boot order to boot from cd and windows goes through like normal and loads files needed, but when it reboots it comes up and should go to the install screen where normally states 40 mins remaining, but it is just blank teal/greenish screen with the curser. I can move the mouse and it doesn't seem to be locked up but never goes past that. I have tried new hard drives, new ram, new video card and nothing helps. I also tried to strip it down to just dvd drive, hd, ram, video card and install that way basically just removing the tv card, media card reader, floppy, cdrom, and soundblaster audio card. When I remove them, it won't boot or come on at all! I figure HP must have something stored in ROM that will not allow it to boot if stuff is removed since it won't power on with items removed or unhooked. I have never had a problem repairing or restoring a pc like this before EVER! Normally if I do, I swap some HW with know good HW and find bad part and replace it. My problem is, I can't find any HW bad on this PC! Motherboard passes post and boots fine, I ran Windows Memory Diagnostic to check and see if maybe MOBO was having problems writing to RAM but all tests are passing with not a single error and it has been running for at least couple hours now or more.
I have racked my brain on this thing for days now and can't figure it out. Only thing I can think of is that the bios has some stupid setting in it blocking me from installing xp pro since it stopped it from booting when I removed items that should not matter if they are connected or not! Has anyone had this problem or know how I can fix it? Anyone know where I can get a bios update for it or a copy of the bios so I could possibly re-flash it. It has pheonix-award ver 6.0 rev 3.13 currently.
Thank you for your time and help with this problem!
