Really Slow start up.

[nbrain]

Hello,
I have, AMD 3.2Ghz X4 955 Processor, 12GB Crucial Ballistix Memory, Asus M4A79T Deluxe MoBo, ATI 5770 CF GPUs connected to 2 screens and Corsair 850W PSU. Plus 3 Internal HDDs. 2x WD 500GB Caviar Black, 2TB Caviar Green. I also have some USB devices connected.
Its on Windows 7 and I haven't had any real problems with it since building almost 2 years ago.

When I first built the system it would boot in 50 seconds, I have noticed it becoming slightly slower to a couple of minutes but that wasn't really an issue. But today when I powered on it hung on the MoBo splash screen for 5min plus, so long I thought it was stuck there and then on the wondows splash screen for another 10min plus. In fact it has still hasn't started up fully, still on windows splash so can't be sure it will.

It entered Asus' 'splashtop' fine and using the file browser all HDDs are recognised and working.

Any suggestions on why it might be suddenly so much slower? I can think of no changes, installs, software updates made since my last start up which, though I didn't time it, must have been well under 5minutes.

Won't let me edit my post so;

UPDATE:
It did start up eventually; around 50min after switching on. PC is running fine as usual. No idea what caused a 50min boot time...

Hi,

I would run virus scan, look for boot kit first.

Do a chkdsk /f/ r

check windows event and in what program is starting with windows

Thanks for the reply- virus scanning now and will run a chkdsk /f /r after-
As for the event log, not had to use it before, I can see a lot of stuff starting on startup. I recognise a lot of it, some I don't- any idea what I should be looking for? Or should I just start googling everything?

Look at running processes with Task Manager, sorting by User Name. Google everything under your username, but do take what you read with a grain of salt. According to the internet gurus, breathing causes cancer. Any process not under your name can be ignored. Also check for fishy applications.
