Ok, first of all, let me put you in the light.

Running XP Pro SP2 and my old PSU blew, causing a reaction and blowing the motherboard at the same time. New PSU has been installed along with new mobo (same as old) all went perfectly in installing. Upon boot up it was lucky all my settings files etc remained and didn't require a reinstall. HOWEVER, as the PC began to install the usb's and drivers etc it came to the graphics card driver and this is where it's gone pear shaped.

Once the driver has been installed (and this has been direct from nVidia as well as the CD) it asks to reboot, which is as expected. Upon reboot the screen begins to flicker and it's all the screen looks dirstorted, it loads into Windows but you cannot see much with all the flickering (most of the time it's a blank screen.

I then boot into safe mode to delete the drivers and start over. I have ensured all the related files have been deleted before reinstalling the drivers for the card. Again the problem occurs, and this has been about 4 attempts with no joy

Now then it's either

a) A complete fresh reinstallation to solve the problem?

b) The graphics card suffered without any signs (when looked at inside) and I need a new one?

HELP a sad mouse please!!

I think it should be a fresh install, yet I am doubtful. What I would like to know is how to do that, I've pulled something off here to help but there are parts that don't seem familiar to me (or maybe I've forgotten). I've got a 98se boot disk as I remember having to do that last time I had a problem and had to reinstall.

Thanks and apologies for being so long

Changing the motherboard usualy requires at least a repair install of xp.

I will quote a reason for this at the end.

A repair install should retain all your programs & settings although you will have to reinstall all service packs & widows updates. Here is a good guide to a repair install:

& here is the motherload:

Normally, and assuming a retail license (many OEM installations
and licenses are not transferable to a new motherboard - check yours
before starting), unless the new motherboard is virtually identical
(same chipset, same IDE controllers, same BIOS version, etc.) to the
one on which the WinXP installation was originally performed, you'll
need to perform a repair (a.k.a. in-place upgrade) installation, at
the very least:

How to Perform an In-Place Upgrade of Windows XP
http://support.microsoft.com/directo...;EN-US;Q315341

The "why" is quite simple, really, and has nothing to do with
licensing issues, per se; it's a purely technical matter, at this
point. You've pulled the proverbial hardware rug out from under the
OS. (If you don't like -- or get -- the rug analogy, think of it as
picking up a Cape Cod style home and then setting it down onto a Ranch
style foundation. It just isn't going to fit.) WinXP, like Win2K
before it, is not nearly as "promiscuous" as Win9x when it comes to
accepting any old hardware configuration you throw at it. On
installation it "tailors" itself to the specific hardware found. This
is one of the reasons that the entire WinNT/2K/XP OS family is so much
more stable than the Win9x group.

As always when undertaking such a significant change, back up any
important data before starting.

This will also probably require re-activation, unless you have a
Volume Licensed version of WinXP Pro installed. If it's been more
than 120 days since you last activated that specific Product Key,
you'll most likely be able to activate via the Internet without
problem. If it's been less, you might have to make a 5 minute phone
call.

Hope this helps.

Thanks for your speedy response! I will try tonight and see what happens

Well, did the above, to no avail, then did a fresh reinstall and again no success. So it's now decided that a new graphics card is called for. Gonna whip it round to my mates and stick his card in to see if that solves it first.
