Vista 64 wont start / bsod

[sxx]

So i got this:

cpu: Core2duo E8400
gpu: Radeon HD 4890
mobo: Gigabyte GA-EP45-UD3P
ram: 2x2GB Corsair 1066 5-5-5-15
hdd: wd caviar black 640gb
psu: Thermaltake Toughpower (W0116) 750W modular
case: Coolermaster 690

Everything worked for two days, the first day i installed vista 64 business (from msdnaa) and it was fine.
Next day i started to update and install things:
1. All the drivers from cds mobo, gpu, monitor, dvd
2. Then i switched cpu multiplier to 9x cause it was by default too low.
3. Linked internet and started to update vista + download programs i needed
4. At the end of the day when i installed SP1, it restarted like 3 times without problems.
5. New Ati drivers , restarted and fine.

Through that time i was copying stuff from my lap which has adaware, avast, windows defender and firewall working.
It was running for maybe 8 hours, cpu temp 26-32C, system 44C, gpu ~60C
And then i noticed new updates in 'windows update' lik 5-6 (the "important" ones) + ie8 (i dont know why i took it)
Restarted, and when windows starts it bsod's for half a second, and reboots.
Safe mode runs ok and it finished updating, i tried 'repair' and recovery from cd but it didnt help, also i checked all cables.
I tried uninstalling last updates in safe mode, but there are no hours of installation only the day so i dont know if sorting by date works.
I dont know anything about voltages but clocks look ok in bios

Please help

its unlikely that your cpu multiplier was " by default too low "

It was probably throttled back with speed step that drops back the multiplier when you dont need the full power of the cpu .

I would reset the BIOS to optimized defaults and see if that fixes your problem

It was set in bios to 8x and it showed 2.66 on load in windows, i changed it to 9x and it was max 3ghz, i know it goes down when not used. Maybe ill try reseting bios, but still comp worked on this config for like 6+ hours and suddenly win doesnt start.

Ive made that bsod stays on screen and it says REGISTRY_ERROR.

I plugged hdd to different sata port and it works!

Yeah, I have had nothing but trouble trying to run vista off a sata drive, but maybe it was just my motherboard, glad you figured out your problem.
