USB conflicts

[Mindoculus]

I have been having alot of trouble diagnosing and solving this issue.

Initially i thought it was a corrupt BIOS. Startup would hold on the ABIT (p35)
LOGO screen and go no further. I stripped that rig down. Re-assembled. Nothing.

Then I come across`mention of a P35 1.8V issue. My GSkill was rated 1.9V.

Bought new ram. Still nothing; hung on the ABIT logo`screen.

I purchased a new mobo - Giga D3 - and a new CPU (Q6600).

Amazingly I had the same issue ! Imagine the shock.

Out I go again and buy a new PSU, replacing my XCLIO 550 with a Corsair 620.
NOTHING ! NOTHING ! NOTHING !!! This time it hung on the Giga LOGO screen.
No BIOS. DAMN !!!

THEN . . . I looked at my mouse, my keyboard, and the USB cable connnection.
Hmmm. Couldn't be I thought . . but i removed my hated Saitek keyboard (bought
a generic MS P/S2 one instead) and tossed my Razor mouse. Replaced it with an
old P/S2 as well. Rebooted.

Surprise, surprise. Problem was far from solved BUT i reached the XP desktop.

Why oh Why ?!?!? Is it a USB driver issue ? I had such trouble with re-formatting
and installing XP over itself when I switched mobos.

Residual driver conflicts post-reformat, anyone ? Is that possible ?

Now I can't get XP to recognize my cable modem. No internet. Thank Jeebus for
free`public terminals. The OS is sluggish. I don't even have the option to activate
the 'new' - ha ha - XP skin. My 8800 GTS can't alter the settings. Stuck in what
appears to be retro-Win 95 mode. Sorry this is so long. I am tired.

What a nightmare.
