Just made a new PC at the end of March and it has been unstable from the get-go. Gradually I have eliminated several problems, like the HIS Radeon video card booting too slowly and crashing the PC, and replaced it with an Nvidia 250 GT video card.
But I am left with a core problem.
On first boot of the day, or one longer than 2 hours since the last cold boot, I get complete instability with cascading program crashes culminating in either a BSOD or a Black screen. It will continue to reboot and crash if I let it.
Now I fire it up, then turn it off for 30 seconds and restart it. It is now as stable as I could want, playing Mass Effect 1 or 2 with no problems for as long as I want, say 10 hours continual use.
Twice now I have had the error on the BSOD saying "not APCI compatible.." but other errors don't give me a clue as to what is happening. All I have worked out, which is obvious, is that on 2nd boot Win 7 sees the problem the first time around and avoids it for the 2nd boot.
I also cannot seem to get DXdiag.exe to run at all...
I am new to using Win 7 Pro as I have used XP Pro for years till I moved to Win 7 in the hope it could cure the problems with my new PC, so not even sure what version of DX I should be using as the video card is not DX 11 compliant. Currently using DX 9c.
Specs of my PC are,
Antec Basiq 550 watt 3 x 12v rails PSU
Motherboard – Gigabyte GA-890GPA-UD3H
AMD Phenom 2 x4 965 processor, 3.40 Ghz
2 x 2 gig DDR3 ram G-Skill - yeah I now know it has issues with this mobo.
Nvidia GT 250 1 gig video card
My old Sound Blaster Audigy 2 sound card.
Bios version says F3 dated Feb 8th 2010
Running Win 7 Pro with current updates.
I would flash the Bios but all I have read online about doing that seems that folk are talking about Rev 1 or 2 Bios and all I have is F3... ??
Thanks for any help you can offer.
