Upgraded from Windows xp to 7 64-bit and now black screen crashes

[ruibo]

I did a clean installation of windows 7 64-bit and now whenever I game or put any stress on my video card, I get a black screen and the system completely locks up. It frequently occurs while playing League of legends but has also happened occasionally on start-up as well as just idling.

I'm suspecting its the geforce 9600GSO 728mb video card or power supply. I've done a clean sweep of the drivers and installed the latest nvidia drivers. I am using a 420W power supply.


I've pasted the cpu-z log onto pastebin if anyone wouldn't mind lending a hand.

sounds like a lack of power.could be the psu.did you let windows update the drivers.

Yeah I would think that a 420w PSU is under powered

Windows did update the drivers automatically as soon as the computer starts up but I did a full installation of the drivers downloaded through the nvidia website.

After cleaning up the drivers it made more sense that it was an issue with the PSU but what really didn't make sense was that when I had windows XP installed, it was working perfectly fine.

I've even reformatted and installed XP back and ran that for about a week with out any black screen freezes.

If it is fine on XP even under considerable system stress then I would be inclined not to suspect the PSU, but, stranger things have happened.

That looks like a really cheap and nasty PSU though, and the +12V rail is very weedy. IMO even 18A on the +12V rail with a gaming graphics card and a decent AMD CPU is pushing your luck a bit, even if it takes a few years for the PSU to die.

One manufacturer's 450W PSU is not necessarily equal to another's. If you want PSU recommendations, I would go with Antec's HCG range or Corsair. I'm using a Corsair VX450W, which has a single +12V rail and can supply up to 33A over it.

Does it lock up during other games? Is that game fully up-to-date in terms of patches? Have you tried Prime95 for say half an hour? You could also try memtest86.

Admittedly the "it works fine under XP" tends to make me think it's a Win7 compatibility issue, perhaps dodgy display drivers (get the latest from the Nvidia site IMO, and/or ask in the graphics forum here or the nvidia graphics forum for possible driver version recommendations). I would also check your motherboard chipset drivers, check that those are up-to-date.

If you want to test out stability use LinX or IntelBurnTest. What takes prime95 18hrs to find can take those 2 programs 30mins or less at times. I personally run them for 12hrs + though to ensure stability on new builds but thats just me heh.

Make sure you monitor cpu and gpu temps while gaming. A good program is cpuid hardware monitor and it can also watch your 3.3volt and 12volt rails.

As far as xp working and w7 not, try running the game in xp mode while in W7. If that doesn't work try a few other games and see what happens.

Either way though, that psu is garbage and should be replaced. The corsair cx430watt is only like 17 dollars after MIR, so it's a steal on newegg right now.

You're right about the PSU, it was included with the case that I picked up. It worked and left it as is but I am probably going to work out an upgrade to an I5-2500k. More like build a whole new system actually.

Thanks for the link but decided to work out a new build. It's about time for an upgrade but I've ran the the IntelBurnTest and the results looks fine to me. I've pasted it below, if you see anything inconsistent please let me know.
