PC crashing and randomly not booting up

My cousin just built his first PC, buying all new parts exept for the hard drive and RAM, and it worked fine for about two days, and one morning it just wouldn't power on. He originally thought it was the power supply, so he replaced it, and it started working fine again for another couple of days.

It had also been having trouble crashing as soon as he played a game. It would run fine in benchmarks and then crash whenever ever you entered games. He eventually fixed that problem, but he had also had been dealing with wifi and ethernet trouble. It wouldn't detect or connect to any other than a slow "custom" network.

After about two weeks of things crashing, not connecting, and testing different things, he got irratated and took it to a PC repair shop. He got it back, and it worked fine for another few days, and would now connect to wifi, although still very slow. (It took 3 days for him to install Crysis 3)

This morning he woke up and it won't power on.

So if anyone has advice on what the problem could be, it would be appreciated. At this point he's about to have the components refunded, get a laptop and just casually game (which I don't want him to do)

I had a feeling it could possibly be RAM, as it's the only component he reused. I told him to try switching the RAM sticks and seeing if that fixes it, but I'm not sure if he's tried yet. Any ideas? Thanks.

I'm not sure about the RAm, it's 8GB of generic Samsung RAM at 1333, it came out of his old HP.

I'd run memtest86 on each stick of ram.

Well, the problem is that it won't boot, and that's the only PC in the house....

Well, it seems he's decided to get a refund on the components and get a laptop. He's not just returning it because it's having problems, but he dicided to spend his money in other places and game lightly.

Make a memtest86 cd and boot it it with all the ram in. Run it for maybe 20 passes. If that doesn't cause it to fail we'll try something else.

Alright, I'll have him try that sometime soon, and get back with results. Thanks.

I think he was going to be getting som new RAM anyway (regardless of failure) so for now I think he'll just go ahead and get it and see if it does it again.
