Hey all My roommates (new) pc stopped booting one day after a lightning storm. Everything else in the house works fine, the power was only off for a second but it seems to have screwed his system something fierce. At first it would say "Missing necessary system file boot failed" or something to that effect. I ended up reformatting, reinstalling and running scan disk. Everything was working fine but now he gets random reboots and such which immediately suggests bad ram. I've been running Memtest86 for the last 3 hours and I can't tell what its doing. Thus far its got a series of columns with various info like memory address and stuff, what worries me is the column for passes says 10 (I dont know how many to run) and next to that it says Errors 43000 and it goes up every second it runs. I'm assuming his RAM is just toast with that many errors but, since I've never really worked with this before I'm not sure what I'm reading here. If anyone has an idea what a good range of errors is it will get me started on the next steps. Thanks.
