I have finally admitted defeat.

This is a long epistle, so here goes.

My dear wife was complaining about her computer seems to be so slow these days, so in my wisdom I said I will build you a new one (Silly me).

The only second hand parts I used again was two 250GB hard drives and an ATI Radeon 5870 graphics card that I brought from a friend that had upgraded to a 6970, and an ASUS Xonar sound card.

I ordered all the parts from one supplier, ( an AMD X6 1090T processor, a Gigabyte 890GX AM3 motherboard, Corsair DDR3 1600 memory and a H50 Corsair liquid cooler.

All of these parts were going into a Silverstone FT01 case with the original BeQuiet 650Watt modular supply.

To disassemble the old configuration and reassemble it took about an hour, then install a retail 64 bit Windows 7 which was pretty quick until it started to do the updates which took with the reboots about 2 and a half hours.

After it was all installed I ran Prime 95 for about 2 hours and memtest for about 4 hours and no problems at all.

Then I installed all her programs and set it all up the way the old configuration was.

Four 4 weeks it ran faultlessly, then it suddenly decided not to load the operating system, it would get to the Windows loading logo and would go no further, so started in safe mode, loaded the picture for safe mode and would go no further.

On the advice of a friend I replaced the SATA cable to the first hard drive and whoopee it booted straight into the operating system.

The following day the wife was surfing the net and had a BSOD, so I went on and disabled rebooting to see if I could find out why, after another BSOD, the code equated to a registry hive error, so a fresh install again with all the updates (Grrrrrr), and booted up to be presented with another BSOD with a different code but still relating to a registry hive error.

So thinking it might be the hard drive, I disconnected the first drive and did another operating system install on the second hard drive, again after about an hour of running it the ubiquitous BSOD.

Tried it with one stick of memory in, then the other still getting the BSOD's, next I took out the Graphics card and removed all the ATI drivers, enabled the onboard graphics and installed the drivers rebooted and it ran for about 2 two and a half hours and then the usual BSOD.

At this point in time I had run out of hair to pull out, and anything else I could test to find the fault, it was then that I admitted defeat and phoned our small local computer store to see if they can sort it out.

I took it there Saturday morning, and they said they would not be able to test it until Monday so I await there knowledgeable answers.

Why not restore the full system (clone) to a new hard drive using the Acronis Backup taken after you installed everything and it was running OK....or didn't you take this precaution?

I forgot to mention that I tried the Acronis back up, and after doing that it still gave me the dreaded BSOD

It will be interesting to find out what the problem actually is.

You didn't try another PSU ?

You didn't try another PSU ?

That was one thing I could not try as I did not have a spare PSU, but I did test it with an Antec PSU tester and it passed, but that tester does not put it under load.

My guess it will be that .............. or the motherboard :)
