Solved BSOD while watching youtube or playing minecraft, multiple errors.

[CloudySkies]

I'm running Windows 7 64 bit OEM originally installed on the system.
The computer and OS are just a few days old, put together on friday.
Basically when i run anything slightly intensive, such as youtube or video games, i end up BSoD. Its a new computer but i don't have any idea what could be causing this. I ran hard drive and memory scans but nothing came up.

Crashes are blaming hardware (they say "hardware"), but I'm not sure which piece of hardware it is.

If you say it happens under load, maybe it is PSU?

Please run these tests and report back the results
1. Memtest86 - Run for 7-8 passes - http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html
2. Prime95 - Run all three tests for 3-4 hours each or until fail - http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html
3. Hard drive scan usings SeaTools - SeaTools for Windows | Seagate - Both long and short tests

It ended up being a bad stick of RAM, which only failed memtest on a cold boot, but using the software you showed really helped me identify it!
