PC is slow and sluggish despite specs

OK first off, I'm no pc novice at all, but this has got me stumped.

I previously was running my pc with 32bit win 7 pro - no issues.  I did something really stupid, in that I downloaded a file from the net, didn't virus scan it at all and of course, it was ripe with 3 major viruses.
Long story short, rebuild of OS was required.  So rather than fix everything I chose to wipe completely and start fresh with 64bit system.  Easy enough since I keep data and OS on separate drives etc....
Also, I can confirm no virus infection of data drives - so virus is not the issue here.

So here's the spec of the newly rebuilt system
CPU - Intel i7 965 3.x Ghz processor
Ram - 6GB DDR3 Corsair (high end version with the heat sinks and bells and whistles)
ram tests good on a 48 hour memtest run
Video - Nvidia geforce 260 PCI-e with up to date driver 258.xx
OS - Win 7 Pro 64Bit
HD 1 - OS drive c:\ (Ridata solid state drive - 64GB)
HD 2 - Data/Apps - 1TB WesternDigital Caviar Black
HD 2 - Data - 1TB WesternDigital Caviar Black
NIC 1&2 - Marvell Yukon PCI-e gigabit nics (88E056)
Broadband speeds testing at 34.6 mbit down and 6.9mbits up to local servers
18.12 down and 6 up across the country

currently the machine has no firewall (other than windows), no AV, no malware etc.. other than windows OS default stuff.  It's fresh out of the box.

Only apps that have been installed since OS are
MS Office 2010 (outlook, word, excel only with the optional stuff kept to a minimum)
Firefox 3.6.8
Download Accelerator Premium 9.4.1.1
Winrar 64bit
Itunes
Xobni add in for email

right after OS was installed I ran a chkdsk and then defrag (using auslogics) - no significant fragmentation, but I defraged anyway.

Windows experience index shows 5.9 (lowest score was the hard drives, all other tests gave scores in 7 to 7.6 range


But the machine is experiencing slowness and sluggish behavior for even the simplest tasks.  For example deleting a 1mb file took 48 seconds, emptying the trash took almost a minute.  Opening my E:\ drive up (HD 2) and displaying the contents seems to take several minutes.  Starting the browser takes several seconds, then it will stop responding for a few minutes, then come back, and work fine for a while then stop.  There is no rhyme or reason to it.  It's all very random.

There are no issues with high CPU usage, no processes grabbing tons of memory.  It's like the machine is a newborn baby trying to feel its way around and just can't get it together. I am almost ready to scrap and go back to 32bit.  I just don't know what to check.  

Any ideas?

Again - it's not viruses - CPU is next to 0% - tons of memory is available, page file is using less than 1GB  The only thing I do notice when it slows down is solid HD light, BUT it slows down some times without HD activity occurring.

Do a hard drive diagnostic: http://www.tacktech.com/display.cfm?ttid=287

I'd suggest trying the memory (RAM) diagnostic tool - http://www.bleepingcomputer.com/tutorials/tutorial146.html

If that succeeds, the hard drive diagnostic (as che6ausc said) should be done too.

I don't believe that I asked for your opinion on my software choices.  Since you don't have anything useful to add, please don't attempt to comment.  Besides Xobni worked fine under 2007 and 2010 and is actually an excellent application.  Beats Outlook's default search by leaps and bounds.  Also, it is definitely not what was making the system work so weird..


I have figured out the issue on my own.  In case anyone ever reads this and wants to know what the problem was...  

As I stated in the post, I was previously running win 7 32Bit OS.  Got a nasty virus due to my own admitted stupidity.  Ended up reinstalling the OS.  During the install I chose to let windows do a clean install over the original, which of course gave me a c:\ drive with a new windows folder and other OS folders.  It also left some data intact on C:\ and created a windows.old folder with old program files, user profile and other data.  My d:\ and e:\ drives were left untouched.  This means that the security on those folders is now in sort of state of flux.  Windows will let me access them but not without prompting me with a UAC prompt in some cases and/or not without taking several seconds to read the folder/file information before it proceeds.  It's almost like an over active realtime virus protection on a very slow or old computer.

The resolution was actually quite simple.  I ran newsid on the system to generate a new security identifier and after that, all the UAC prompts, HD activity and slowness is gone.
