Re: how to diagnose if it is bad GPU or bad GPU RAM

Bad video ram would crash the system.

Could be two things, bad chip or bad soldering. Bad soldering is less likely to be. Higher chance to have a bad chip, what date code is the chip?

Re: acer aspire V3 771 crashes when battery get's inserted

check charging circuit mosfets.

It's easy to find, just follow traces from charger port.

Charging mosfets activates when battery is inserted, on v3 772g that's how it is.

Re: Hp G62 no display

Sorry for red tape, but there is a different thread for bios request.

Have you tried to check ram first, instead of reballing chipset.

If you put faulty ram you get the same result.
