Hi m using a hp dv6-6052EA notebook. With a 6490M 1GB GDDR5 and intel 3000HD switchable graphics built into my i7 processor, i did a graphics driver update for both cards (same install package) from the hp website, during the install it blue screened of deathed me and error about graphics drivers. I rebooted it and loged back in, now only the intel hd graphics adapter shows in device manager, even when in high performance, the amd nstaller cannot find my 6490m (even the hp drivers cant) so im unable to nstall it. Please help me,
