please stop using your few installs as fact... after thousands of Vista installations under my belt... Vista installs, boots and runs all around slower than XP in any given system with direct comparison on fresh clean installs.
Sure if you compare a 3 year old XP install that has the years of...
one portion of chkdsk checks the data, and if it sees it is corrupted it tries to fix it... another part checks the drive itself like scandisk...
either way if there were corrupted files to begin with then it was hosed before you touched it, and Vista only tried to fix them, not break them...
chkdsk in Vista is the same as it is in XP. It only checks it and fixes problems if any are found. Otherwise it makes ZERO changes to how the files are accessed.
I suspect that the OS was corrupted on the hard drive before you touched it (why else was the system sitting there unused?) so you...
may as well find used systems on CL or local ads for $100-200 to handle this stuff...
personally my next system will be a core 2 or quad core using a VM for the LAN server stuff...
of course it is all an advertising ploy by MS.... do you see any videos of people that still did not liek it in there? nope... if it was unbiased they would have posted them good or bad... either way it is a decent way to get people that only "heard" Vista was bad an refused to even try it, may...
my best offense?
boot into safe mode and run the full system scan/clean with Avira and SuperAntiSpyware which takes care of it all. The other programs/anti-virus doesn't remove the registry settings and will just let the system get reinfected. NOD32, Kaspersky, AVG, Norton, Mcafee, they are the...
I can get just past 3.1GHz with no voltage bump on my E6600 on Gigabyte EP35-DS3P system... and on my P965 board a year ago I couldn't get it past 2.8GHz. These E6600 tend to top out (aka STABLE) around 3.0-3.2GHz on most systems. If you want any more speed or better Oc on something, time to get...
if it goes wrong then you have a nice new doorstop :D
kidding, most boards now have "dual BIOS" so if one goes wrong it can boot from the other and possibly fix the first...
and yes any settings or OC you may have will be reset back to factory defaults when flashing the BIOS which is good...
in your case I would suggest the GTX260 simply because of the CAD and engineering software. ATI consumer based cards do not always handle those very well.
