Windows 7: Flickering / Horizontal lines on screen of Acer Aspire X3450 (HD 4250)

Flickering / Horizontal lines on screen of Acer Aspire X3450 (HD 4250)


Iam reinstalling Windows 7 for a friend after a HDD failure. as soon as I download the relevant chipset drivers from the Acer website (which installs the ATi 4250 driver) the screen is not only under-scanned (on HDMI @ 1080p/60) which I can fix... but as soon as anything fills the screen other than the desktop background it starts to get lines flickering on the screen and the screen flashes off and on ...usually spends more time off than on, its only ok (and under-scanned) on the default driver MS installs...if I could only over-scan it .... my friend said it was used on HDMI at home on a 1080p set but I dunno if his is 50hz or 60hz and he probably wont know either..

its a Acer Aspire X3450 with 6Gb of RAM and AMD Athlon II X4 645 @ 3.1Ghz with an onboard ATi HD 4250

can anyone help please?
