i need a 2nd opinion
i was handed a laptop that is having a problem with the screen pixelating very badly at random times. ( hp G61 ) and it also does it on an external monitor when hooked up. and the pixilating also will happen after a short time sometimes ( running the one test ) or sometimes not for days

i ram an old diagnostic called quicktech pro it found a couple different types of memory errors. next i toss in memtest 86 and at about the 20% way through it crashes and pixelates the display and everything is non responsive. have to hard reboot it.
i then opened up and took out the ram and tested each stick individually in separate slots and same results now i am doing the windows 7 memory diagnostic tool it is stuck at 21% for the past hour but not reporting an error nor is the screen pixilating.

short of finding some other compatible ram and testing it in the machine does anyone else have any idea what it may be besides bad ram? i was thinking could be a motherboard problem also with the ram channels

RE: i need a 2nd opinion
I'm pretty sure the computer is dead or at lest brain dead Confused
Since virtually all the part are on one PCB I think the only thing to do is take the HDD, put it in another computer and backup the data.
And maybe give the laptop to an art museum.

RE: i need a 2nd opinion
does the laptop have onboard video? if so, judging by the other symptoms and that onboard video shares system memory, i'd say that it has bad memory. the actual memory sectors assigned to the onboard video is different with every boot, which explains why it is sometimes giving memory errors, and sometimes having graphic corruption.

RE: i need a 2nd opinion
since it is a laptop it is for sure using onboard video. i was assuming bad ram from the things i have seen but i suppose i will need to find some other ram to test with.
i suppose the problem truly is until i can take out the ram and test that ram in another system and test the system with different ram no real way to know if it is the ram that is bad or the motherboard

RE: i need a 2nd opinion
you can probably just buy the right kind of ram at CC, test, and then return it. it's usually a full refund within 15 days.
