Tried cheap upgrade, but no video!!!

[ranger007]

Hoped for a cheap upgrade from older Pentium to AMD Duron 1400.

1) Removed Pentium MB with PCI cards

2) Installed Matsonic 8137C MB (which was also working when removed 2 weeks ago from another computer - it does have a recently flashed BIOS), along with Duron 1400. AGP video card, memory and PCI cards reinstalled from old Pentium computer.

3) Powered up -- no video

4) Checked connections -- of course!

5) Exchanged memory with different sticks (used both DDR and SDRAMM - separately - MBR supports either

6) Changed to different CPU chip (Duron 1600)

Never got video.

7) Reassembled old Pentium, it works fine. I know the memory and extra CPU works, I'm using them installed on a different, separate computer as I type this.

Any SIMPLE suggestions? Shouldn't be monitor, video card, memory, cables, or etc. They are all working now. Might be the motherboard, but it was working when I removed it from another case 2 weeks ago.

We did double check connections and etc. Are we just overlooking something obvious?

Thanks for the help.

When you state "no video" do we assume that the PC is NOT booting at all?

Or are you getting the BIOS start-up screen but no Windows video?

Sorry for the questions, but if there is absolutely no video, then its likely there is no boot at all?

If its only POST / BIOS video, then the problem would be with trying to run a previously installed version of Windows on a new motherboard, without a reinstall. Thats a no-no as it force feeds all the wrong chipset drivers at start-up.

That would not prevent a boot to BIOS however, so the problem could be more fundamental. Such as no boot?

Sorry I didn't make myself clearer -- when I said no video I meant nothing on the monitor at all. Can hear something going on, but see nothing.

Thanks for your reply

PS - I was in Christchurch a number of years ago (30+) -- thought NZ was great. Mainly saw the eastern and northern part of South Island

Pull the problem board from the computer and place it on a non-conductive surface. The mb box is great for this. Install just your video card and one stick of ram. Connect your monitor. Now connect your ps; you may have to pull the ps from the case. Find the power switch leads on the mb and short across them with a small screwdriver.

If it posts now, you have a mounting problem in the case. If it does not post now, you will need to swap parts with known good units ie ram, ps, etc.

BTW Matsonic is made by the ecs group. I would not put much faith in the mb.
