After new HDD install, computer does nothing without freezing

Hey all, i need some help! I purchased a 3TB hard drive yesterday and installed it without a hitch. I backed up all my files to it and proceeded to fill it up. I left my computer on overnight downloading a large (64GB) file. This morning i found it was frozen on the windows logon screen, (which was weird because that means it restarted at some point). After a restart, The computer Froze at post. I unplugged the 3TB hard drive and can boot into bios no problem, but cannot load windows from the other hard drive, it freezes at windows startup logo. So i unplugged ALL hard drives, hit the CMOS reset button and took the battery out, put the battery back in and tried to load my windows 7 disc WITHOUT any hard drives plugged in, It freezes during the 'Loading Windows' process.

I will keep messing with it but i really dont know what else to do.

Thanks,

This freezing doesn't seem to be a power issue, but i will check that out!

Here is an idea:
Try not only removing the CMOS battery, but make sure that the line cord is disconnected from the computer too. WAIT 1 Hour and try to log into the BIOS with NO devices attached. If you can do this, then you will want to try connecting the DVD drive first and see if the BIOS sees it. If that is not successful you either have a bad drive or something wrong on the motherboard. If it is OK-then reconnect the old HDD and test again. These tests will help you find the cause if it is not a faulty power supply. I do not recommend anything smaller than 500 watts these days, btw.

You don't tell us anything about your system so I will guess that it is possible that the BIOS is unable to deal with a really large HDD such as your 3TB. I know of a Mobo that only supports up to 2TB total and there are cases where they have failed to function properly with anything larger.

I am using a custom built pc with an
MSI Neo4 Platinum Mobo
4GB ram
1GB Nvidia
3 Hard drives
80GB Maxtor (primary with win7 installed)
250GB WD
3TB WD

The Bios reads the drives no problem and the thing that really confuses me is when ALL hard drives are unplugged, it freezes when i try to boot the windows setup disc.

I will try the one hour unplug though thanks

alright, i've figured it out, the 3TB drive was causing problems, but now can only use the 3tb drive in an enclosure (which means the speed of the drive has significantly decreased)


if anyone else has this problem or any more ideas I'd love to hear it

You may need a BIOS update to run a HD that large. Check the maker's SUpport Downloads webpage.

Partitioning it into smaller sizes might also help.

I'd also update my PSU calculations: Psu calculator - Windows 7 Forums

Its good that you have figured it out. But also check your fans to make sure they're still working and your machine isn't overheating. Also check the power plugs.
