I would say, that not for the first time, Bill is wrong.

A single re-boot switch on the keyboard would make it too easy to make a mistake.

Here's an issue I've never come across before. Booting up my system on Friday all I got was a black screen with the graphics details showing and a flashing cursor. It would not proceed to the bios followed by O/S booting.

Rebooted several times same issue. POST ok. Thinking it could be an issue with the GPU shutdown and replaced graphics card.

Problem solved. Used system for the rest of the afternoon, also over the weekend.

Returned home this afternoon and booted up, same problem, so again replaced with another GPU. The original was a Geoforce 9500GT 1gb, replaced with the same model but 512mb which I've replaced with a 512mb 7300.

Shutdown while grabbing a tea to test my suspicions. Rebooted, same issue.

Is the PCI-E slot failing or is there another issue involved?

System currently ok and in use by using onboard graphics.

Had a spring clean the weekend before. It's a fairly newish PSU, but it's an idea to swap it out to test.

Will run memtest overnight.

Edit. Since it first happened on Friday, left the rig on 24/7 over the weekend. It only seems to happen after a shutdown.

Swapped out the PSU, same problem. No Ram issues and gave it another thorough clean.

Shut system down. Booted up 10 minutes ago and got this.....

A Windows Update gone bad?

Anti-virus silliness?

Try a HDD check just in case corrupt data is being loaded...

Try a system diagnostics from a LiveCD to make sure all the hardware really is ok?


Sorry, more clues needed. Looks infuriatingly random...

Good luck,

Looks like a I/O bus hardware control chip went south or a broken trace / cold solder joint.

With an error like that, and since you've ruled out the PSU, it could be from any other major part in your PC.

From my experience, here's what I'd do.

New hard drive (or known good hard drive). Clean OS install. If you still get this error:

Use this as an excuse to upgrade with a new motherboard, CPU and Mem. Less time wasted, less heart ache, less head aches, lower blood pressure, *potentially* the cheapest way to go and functionally a new computer (yeah!).

I've spent hours and hours and hours of my life (and I refuse to do that anymore) trying to determine if it's only one of the three above parts that are failing and sometimes when I either put an unknown part in known good parts or put known good parts in unknown parts, I end up burning something else up and I never can figure out in the end if there were originally two or more bad parts to begin with.

Depends how many times you've been through the above exercise. If you have never done it before, you may want to run through it and see if you can save a few quid. If you've done it as many times as I've done it before, it's cheaper to functionally buy a new computer (compared to what I feel my time is worth these days.)

Motherboard
CPU

Which do you swap out first? Motherboard is cheaper. But if you buy a new motherboard and it still doesn't work, then you have to buy a new CPU, which means (depending on what you currrently have) you can't upgrade to a newer/faster/etc CPU. If you start with the CPU and it doesn't fix it, then you can't upgrade to a newer/faster/etc Motherboard. And if you do it one at a time and in the end, nothing works you've not only started out with a bad motherboard/CPU, but you've also burned up a new motherboard and CPU. Been there, done that. Sucks. So I don't do it anymore.

I have a couple lab computers in my classroom that either pass memory but lock up when I try to load an OS or they pass memory and after loading an OS, I get totally random BSODs and I have one that fails memory even with known good memory sticks. I'm done with those. New motherboard, CPU, and mem for all of them.

A bit of technology that could put all the energy firms out of business.....

I can only hope that nothing bad happens. house wireing is nothing to play around with when it starts acting up.
