Motherboard Not Working with PCIE

[Muntz Street]

Hi there, I've had a Biostar G31-M7 and ran it a 1GB NVIDIA for a couple of years without any issues until now.

When I turn my computer from a cold start on it boots for about 3 seconds before suddenly turning off and restarting the process again. It usually takes around a dozen reboots before the computer actually boots properly and from there I can use my computer normally.

The problem seems to revolve around whether the graphics card is in or not, when it's in I have problems and when it’s not it boots up straight away.

Already replaced the PSU, tried a friends graphics card and still having the same issue. I'm guessing I have a faulty motherboard?

Many Thanks for any advice in advance.

It would appear your assumptions are correct, sounds like a break in the motherboard coming from the PCIE slot

Could it be anything else at all before I replace the m'boad? Anything I could remove or tweak?

As I said earlier, already replaced the PSU and test tried another graphics card. What confuses is me is that it eventually does boot up and runs fine.

Thanks again.

What was the previous PSU and what is the new one (brand and rating)? I've gotten some that were DOA before, back when I didn't know any better and bought whatever was cheapest.

Memory

Could be the memory , you can do a memory test at the Microsoft.com site, then do a search for memory test software and down load that to a floppy.
Or, if you have more then one memory strip installed, pull one out and see what happens, do that with all the strips.
It will boot and go into the O.S. and then shuts down and restarts, almost 90 percent sure it's memory.

Good news! I have replaced the motherboard and everything works fine, including the graphics card.

Thankyou to all who helped.
