Hi,
I recently bought an XFX Radeon HD5770 GPU to replace my old Geforce 7800GT but have had nothing but problems since I got it. Before I put it in my computer, I deleted all the old drivers and used driver sweeper in safe mode but I got the following problems:
- Catalyst installer crashes when scanning my hardware prior to software installation (doesnt matter what version i use) so can't install drivers etc
-5770 doesn't show up in dixdiag/device manager/bios etc
-To get around this I manually selected the .inf file in device manager to force driver to install
-Worked fine for 1 day (could play Fallout 3 maxed out) then screen started freezing for ~2secs every 5 mins and then refreshes. After ~30mins of this, the 5770 drivers uninstall and don't show in dxdiag :/. Main driver is then displayed as vga.dll
-Decided to format HD and reinstall windows to see if this would help but now there is no display on monitor when the 5770 is inserted (currently using my old card)
I have no idea what's going on and would be extremely grateful if anyone could offer some advice/suggestions.
My system stats are:
AMD Athlon 64 x2 5200+ @ 5700mhz
Gigabyte M55s-S3 Rev 2.0 motherboard
4GB Crucial DDR2 RAM
Magna ATX 500W PSU - 17amps on 12v rail
Windows XP Operating system
Thanks very much for any help
