Event Error 100 Slow Boot

Hi,

(I'm a newbie on here, so I am open to suggestions on improving my posts.)

Despite an impressive machine spec (which I think you can view in my profile?), my Windows 7 PC takes over 2 minutes to get to the CTRL-ALT-DEL login prompt, then about another minute to give me a usable desktop once I have logged in. When I first got it, it booted in about ten seconds. I have installed a lot of stuff since, but, short of starting from scratch and trying to identify what has slowed down the boot, I don't know how to identify the problem.

I have tried running xbootmgr and viewing the results with xperf, but no single item seemed to stand out (though admittedly I found the report to be way too complicated).

Can anyone please suggest anything I might try that doesn't require me to spend a month learning about Windows internals first? I don't mind putting in some effort with this problem - I don't expect a free solution - but xperf seems to require a lot of very specialised knowledge.

Any help at all would be very much appreciated.

Tried most of that. Nothing seemed to have any real effect. I could start disabling startup stuff more aggressively, but, to be honest, everything that starts now is actually stuff I use. I'd expect a machine of this spec to handle this. My gut tells me there is an anomaly somewhere in the boot process, but I just don't have a month to play about with it.

Thanks anyway.

I tried the first two of those, and they didn't find anything. Couple of cookies - that's about it. In view of the results with the first two, I didn't try SuperAntiSpyware. I don't believe I have a virus or malware, because I have always had anti-virus software installed and I am generally very careful about what I click on.

Thanks anyway.

Kind wishes ~ Patrick
