Computer freezing...

[Trillock]

I get random freezes with my puter. I can be just viewing a web page, and it will just freeze and I have to hit the 'restart' button to get going again. It will occaisonally freeze in a game, my latest one is Code Name Panzers II..........it is very annoying....
Just in case, I have done a fresh install of XP Pro, with SP2, all updates/patches from MS, and all latest drivers.
I am wondering if it might be my Tagan 530W EasyCon, because I have a seperate problem with it, as if I happen to nudge the power cable plugged into the unit, it will click and shut down. This happens if I stick my hand at the rear to remove/insert a USB cable and nudge the plug..............'bam'...off it goes...
According to the Abit software monitoring the volts seem fine, and like now, the +12v reads 12.05v. I have used a DMM on some molexes and the 12v reads round about 12v.
It 'seems' to be putting out the power, doesn't run hot, and is nice and quiet.......I can't hear it over the fans in the case.
It is running an Abit Fatal1ty AN8 Ultra, X2 4400+ with a Zalman 9500 Cnps led cooler, 2 x 512MB sticks (matched) OCZ Plat rev2 PC3200, 2 x 37GB Raptors Raid 0, 1 x 250GB WD Sata II, 1 x 120GB Maxtor Sata I, Audigy 2 ZS, BFG GF7800GTX OC 256MB, 2 x Lite-On CD/DVD writers, 3 x 120MM + 2 x 92mm fans, and 2 x 40mm memory cooling fans.
I have put XP onto a Raptor, and tried on the WD 250GB, so the OS has been installed on different drives, but I still get the random freezing.
It doesn't happen so much in games.............I can happily play BF2, but it can happen at any time whether the puter is being worked, or just idling.
Sometimes the computer won't start with my DVBT USB Freeview box plugged into the computer or the USB (powered) hub................it gets to the first boot screen and hangs, if I pull out the USB plug (trying hard not to nudge the Tagan power plug ) it starts up just fine. Sometimes it starts ok with it in, sometimes it won't.
Sorry to ramble, but am trying to provide all the info I can..................

If you've got a known fault with something on your box, personally I'd replace that first.

That way you eliminate it from the equation.

Thanks............I intend to buy another PSU once I have decided on the make, and keep the Tagan as a spare.
I shall be a bit peeved if it makes no difference though...............but I won't know until I get one

Can you borrow a psu off someone, that way you'll save the expense if its not psu related.

Unfortunately, no.
At least, not one that I would install without a lot of finger biting..........
I am rather tempted by the Corsair that JonnyGURU reviewed, as it would provide plenty of power should I go SLI later, plus it has a 5 year warranty, which can't be bad.
Even if it proves the Tagan is not at fault, I would keep the Tagan as a spare, as it is always useful to have a working one, just in case....
