Upgrade On Acer Aspire 7535g

This is my noob experience of the £699 4 months ago 17.3" multi spec't acer aspire model 7535g

ATI mobilty 4570 radeon twin graphcs job

£12.78 buys two discs to get me from vista 32 home premium to windows 7 home premium 32bit

1 upgrade disc and 1 windows 7 media disc

I decide to go with a clean install so i changed boot sequence in bios to cd first, then booted from the windows 7 media disc.

option 2 custom install i managed to delete partitions which made my restore discs effectivley scrap.

realizing there was no way back, i had to instal windows 7

all went silky smooth untill the device radeon 4000 series had code 10 cannot start

i let windows 7 update this device - rebooted...the screen never came back...the machine was ON,signal up and everything but no raster, just a mouse curser.

hmm... rebooted in safe mode, rolled back driver....screen ok but still the graphics 4570 is code 10 and cannot start.

so i inserted the acer upgrade dvd

and ran all EXCEPT the amd puma driver

rebooted

all ok

then i ran the puma driver, rebooted and the screen never came on...backlighting but no picture.

Holding down the power button i just turned it off, rebooted, pressed f7 or 8 whatever key for safe mode and chose

ENABLE LOW-RESOLUTION VIDEO (640x480)

enter...

starting windows...4/3 aspect

right click - screen resolution

change to 1600 x 900 (recommended)

no more errors
