Very Very Slow Cold Bootup

[Geminite]

Hi, I was just wondering if anyone could figure out a problem of mine.

I don't understand why my computer cold boots so slow. It takes around 5-10 mins to start up while a warm boot would take 15 seconds.

The computer seems to be loading a lot of stuff when I cold boot, but I don't know what would be causing it. I already have tweaked my computer to boot as quick as it can (disabled uncessary services, used bootvis)

I set my anti virus not to scan on start up, so I don't know what else it could be.

I tried both WINXP + SP1 and WINXP + SP2 and the problem is the same.

I'm running a
p4 3.0
512 dual channel ram
radeon 8500 AIW
2x 200 GB Seagate HDs

Can anyone help me figure this out?

Thanks

What are the specs of your power-supply? It might be under-performing, if this is one of those cheap PSUs that come with a case, when you build your own.
Check for dustbunnies in the fans of CPU, PSU and AGP-card.
Is 48-bit LBA enabled in BIOS for those big harddisks??

Thanks a lot, I will try that.

I'm running a good PS: Zalman ZM300b-APS (the noiseless switching power supply)

I tried most of the usual stuff like Bootvis, disabling useless services, defragging.

I'm just wondering what could be causing such a slow cold boot, while a regular boot is so fast.

Thanks again.
