I have a custom built computer that has been running perfectly for the past few months and all of the sudden started running very slowly. Here are the specs:

I7 - 930
12gb ram
1tb 7,200rpm internal hdd
1.5tb 5,400rpm internal hdd
Nvidia gtx 480
lg blu ray burner
DVD burner

Finally the computer started having errors at startup and kept doing a startup repair. EVENTUALLY Windows WOULD load, but would be ridiculously slow. It would take a couple minutes (sometimes more) to respond to anything. EVEN a mouse click. I decided that I would format the hard drive and re-install everything. After I re-installed windows and installed all of the necessary drivers it was still being very slow.

The only hardware I've added recently was the blu-ray burner. It has been working fine, but maybe there's something faulty with it? I'm not sure what to do at this point, but I need to figure it out soon. This computer is used for video editing at a school and we need it.

This computer is not hooked up to the internet on a regular basis, occassionally I will take it home to install updates.

Any help or suggestions you can give would be greatly appreciated. Thank you!Welcome to the CH FORUMS. Perchance did this change in performance begin at the time of the Blu Ray hardware device? Were there any software additions or updates coincident to this change? Is the computer still under warranty? truenorth If you right click on Computer and select PROPERTIES, does it show the correct processor speed and correct amount of RAM?
