PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

Buffalo Intros Tiny USB-Powered 3 Port Ethernet Switch

um, ok so this is just laning correct? only 2 pc's can connect correct? then why not just use a cross over ethernet from 1 pc ethernet port to the other pc's port instead of paying for this lil ethernet switch?

 

Ethernet port not blinking...

possibly your ethernet port has died...

Unless if you format/reinstall windows , and see if that way... but overall, physically take a look at the motherboard in the computer, and see if any capacitor's top's have blown open or even have a bump on them (the tops of the capacitors should be flat) . If any indication that happens, then your mobo is eventually gonna die.

Other than that, u went through all other steps that are very known..

**My Friends system not to long ago has the exact same issue, and there were caps blown, but only the ethernet didnt work
