Homebuilt Computer... Slow turn on...? Cold boot...?

[alphakp295]

wsup guys,
I came back for some answers to my question...
I have my system... e4300 @ 3.6ghz with 4gb ram in intel bad axe 2.
It was running fine with my 600W seasonic couple of months ago...
back then, my comp was @ 3ghz.
then, i changed my psu with thermaltake toughpower, higher rated than my old seasonic.
since i had more powerful psu, i've decided to oc to 3.6 ghz, which i'm at right now.
here's my problem...
when i start my computer, it takes 10 seconds or few minutes to actually starts up.
Until it starts up, it makes loud fan noise from videocard and light blinks from all dvd drives.
after it starts up, it runs fine without any artifacts or errors; orthos 80hrs no problem.
the system is rock stable...
but i got sick and tired of long wait!!
i thought it was my OC that gave me that problem; now it's underclocked to 2.4ghz, it has same damn problem...
could it be artifact from my OC?? or would it be faulty PSU?? my psu rail voltage has no problem 12.0v and 5.01v
any of u guys can help me out??
thanx in advance

I once had this ame problem with my pc, it ended up being a usb device (drawing pad), so check that, also did it do this when it was at stock clocks? also i imagine yuve tried reseating all components? a offset HSF can cause this.

USB drawing pad?? I have a graphire4 attached to one of my USB...
I guess I have to try it as soon as I get home tomorrow...
It also has same issue at its stock clock.
I don't remember if I had the drawing pad before I changed the psu.
What I remember is I had a seasonic with good boot... now it hangs for a minutes...
I guess first thing I'll have to check is my drawing pad.
Thanx so much =)

Well... my hopes didn't get through...
Unplugging my drawing pad did not work.
In fact, pulling out all USB attachments did not work either.
One thing I found out for sure is...
It works if I pull out my sound card, DVR Card, and Two sticks of RAMS.
After pulling those out, it works like charm.
No hang up on booting, just instant boot up even @ 3.7GHz OC.
What would the problem be?? PSU?? Mobo?? any other???

PSU problem I would say.

Can PSU have low power problem even with correct voltage of 12v and 5v?

Most PSUs, any rail can brown (underpower) or drop offline. The circuitry that makes each rail is independent of the others. There is a transformer for each rail, if that transformer fails, that rail goes down without affecting the others.

I suppose there is an obscure supply out there these words may not apply to, but in my experience repairing them professionally, most work this way. Seeing a PS with rails down is common with regard to lightning damage.
