Windows vista simply won't run efficently.. if at all.

ASRock N68-S UCC motherboard
AMD Athlon 7750 dual core 2.7ghz processor
4 gig patriot ddr2 ram
Nvidia 9400 GT


Okay. I originally got BSOD'd while trying to install vista with the driver_irql_not_less_or_equal nvstor.sys. i was able to bypass this by messing with the bios disabling various thing while limiting voltage on the RAM, shutting off sound card, etc.. Now that I finally (after 4 days) have managed to install windows, it now barely runs. First time after install it worked (slowly, but managable), when I noticed my internet wouldnt go above ~2kb per second so i shut it off, went to look up a solution, then when I tried to boot up again, I couldnt get into windows whatsoever and was forced to reinstall. So I did that again, and now it's even worse. It takes 10-15 minutes to simply log in, then just to get the "welcome center" window up and the computer to stabilize, another 10 minutes. This is if it even can get to the log in screen to begin with (i've sat for up to 20 minutes and nothing)

There is something seriously wrong here and I do not understand how. I do not want to sit here and reinstall again seeing as though that didn't help. I reformatted the hd before freshly installing windows. Everything is in place in the computer. Does anybody here, that knows more about computers then I do, know whats wrong?

 

Welcome

Reset the BIOS to default or safe settings, install the latest drivers from the chip makers - nVidia (or Intel) chipset + graphics/network - Windows Update if you must, test in Safe Mode with Networking if no improvement, run the makers diags on your hard drive.

2kb = wet string, only Windows Messenger can cope with that

I'm logging off to get some sleep, good luck, I'll look in later.

 

Is this a fresh build (physically)? If so make sure your CPU and RAM are seated properly.
Did you physically install anything? If so make sure it's seated properly.
Does your CPU fan work?

 

I have triple checked all the seating so that can't be the issue. I would barely call this a "fresh build" so i guess it could possibly be a hardware problem yet I wouldn't know which part. I have been having to reinstall windows almost every other time I log on. Like today I reinstalled this morning, did nothing but install and updated Ethernet driver. Then when I tried starting it an hour later I couldn't get into windows at all. Not through safe mode, not through last good config, nothing. So, now i must reinstall again, yet I barely see the point when it wont even run next time I try to boot it up.
