My first Vista problem

FirebarUK · 8 Mar 2007 at 12:05

I've been running Vista x64 on a Core 2 Duo E6600, 4GB RAM and an Abit QuadGT for a while now without any major problems. Today I swapped my Core 2 Duo for a Quad Core QX6700. Now Vista refuses to boot, it just hangs when at the welcome screen. XP loads fine however. I've tried reinstalling Vista but it does exactly the same thing, installs then when trying to start the display manager (or essentially boot me into windows) it hangs.

Any ideas? I'm a little stumped, seeing as XP works perfectly its a little annoying!

I should say that it loads up fine in safe mode. Nothing dodgy in device manager. If the install fails to load I can reset the PC and go into safe mode, but of course the setup cant finish in safe mode

No-one?

Anyone experienced something similar?

It seems your Bios may have to be updated to cope with the QX6700. This is the most common problem attached to this kind of native reaction. The Bios reaction on how it hadles RAM and Frontside Bus Addressing seems to be at the foot of the problem. what MOBO have you got? Is it by any chance an Nforce or an ASUS Mobo. Bios seems to ASUS main weekness whereas ABIT, DFI and MSI etc seem to have a memory timing feature which has to be reset and recalculated on setup. ECS also have Bios and Driver problems when using the Quad Core Extreme Processors. First try and take 2GB of RAM out of the System to see if it boots without the extra 2GB. This will lower the threshold for error in the MEMORY latency timings. If it works fine with 2GB instead of 4GB then you have a memory timing error. If you are an Overclocker then you need to find the correct memory timings to address all your ram Adress space.
