Hello, I just put an old system together for my nephew. It's an ASUS P4P800-E Deluxe. MoBo is good, memory is good, power supply is new and good. video card(s) are good along with the monitor(s) Now, when I turn on the power supply, everything works, but there is no video display. I changed the video card three times, then tried two different monitors. Can anyone give me ideas what to look for or do next. I'm almost there, but no video. I've appreciate all the assistance I've gotten from MDLF, and I rely on MDLF because there is no BS, and there a lot of very talented and knowledgeable people that support MDLF. Thank you again and in advance for assistance with this minor issue.
Thank you for replying. I did check all the jumpers, and everything is at the default settings. Then I took 1 GB stick and used that, checked the CPU for any bent/bad pins, non found. The CPU P4 @ 3.0Ghz, same as the original. Going to get a new battery tomorrow, even though the three I had as spares didn't help. I connected the floppy drive and a hard drive, which is a 500GB WD Black drive, which is a new drive, I know, the drive COULD be bad, but when I turned on the power, the floppy drive and HDD were acknowledge, but no video. The monitor is a viewsonic, which I know works because I hooked my laptop to it with no issues.
From my point of view, the use of a connected speaker to the MB is mandatory in first place! It will give you the info the MB is still working in at least some part! If no any beep sound come out from that speaker, it's the MB which has the problem! If there some Repair shops in your area, I would friendly ask them for to check the MB is still usable, because they have the knowledge and also a lot parts to use for testings! There many parts on a MB which could go, like Capacitors, Resistors, Chip Set's and more, which maybe could be easy changed. The question just is: Is it worth for that 10+ years old MB?
Please post a pic of the motherboard. Maybe one of the members here can see something that's amiss (bad / swollen capacitor)
how about trying a different video card if he has one or trying that video card on another comp. sound like bad video card or issue in PCI E slot.
All those actions with Graphic Card, etc., etc., are useless if the MB has problems! First step is to really check the MB is working, and that should be done by some technician who knows the How to......, if the owner didn't able to do that, as it seems to be! If the owner connect a speaker as suggested, and there isn't any (even single) Beep Sound, the next step, after done already that test's as posted by the OP, is to ask competent people for to do the checks, and that would be someone with the required technical knowledge, who may works in such service!
