Hi guys,


I recently upgraded the graphics card in my old box from a Geforce4 Ti4200 to a Sapphire HD3650 (AGP).

This was thanks to some very helpful advice from guys on these forums.


Problem: With the new card in after 10-15 seconds of running, my computer hangs. (i.e. completely freezes)

I have tried the following:

Trawling through my BIOS looking for any settings which affect the GFX card, but found none that I understood.

Upgrading the PSU from 300Watts to a Corsair 450Watt

Running the computer in safe mode, and installing crad drivers from the disk provided.

When I tried to install the latest set of drivers, it wouldn't let me. I can't do it from safe mode, 'cause the installer seems to require .Net 2.0 which doesn't run in safe mode. I tried putting my old card back in and running the latest installer, but it says it can't find a driver for my hardware setup.


Any ideas????

If it's the PSU, I can take it back to PB Tech on Monday and trade it for a higher wattage one (550Watt).

I heard on another internet forum that it was the PSU, but I've upgraded it and still no change....


Please help, I'm desperate!
