Windows 10: Ok now my pc wont start up

My Lenovo B750 Laptop won't start up from the Windows setup USB when i erased it. The reason why I erased it is because I was trying to install a version of windows and on the setup, it crashed. but it installed system32 files . So whenever I started the setup even with another ISO, it would keep blue screening. What do I do?

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??

 

PC wont Start Black Screen (keyboard,mouse issue)

Ok.. after reading some of the replys, Some of this has gotten mixed up. So il Sum everything up.

Ok firstly I have Two Pc's One of which i have listed Under my name is System Specs which is Running Windows 7 and My other Pc which is Windows Xp which is the one with the problem Specs are Below.

AMD 245 2.9Ghz
4GB Team Elite 2x2Gb
Asrock N68-s Mobo
160Gb Hard Drive
550w CIT PSU

Ok For some Reason my Pc Refuses to Start up with a Keyboard and mouse in the Usb port All i get is a black Screen and so far the only way to get the pc in is if i keep Press ANy key on the keyboard and keep clicking on the mouse But this does not always work. I have tried A loads of Different Keyboards Mouses Etc... But none of which Seem to Work.

i have Tried all the Suggestions Given to me wont list them as there are loads now...Lol
However one of the Suggestions Did kinda work which was to Connect my Keyboard mouse Using a Ps/2 adapter which Seems to be working ok But not fully sometimes it dont want to start up again say 2/10.

Yesterday i Went to a Friend of mine who is Pc Engineer and we connected it up Using His Psu and His microsoft keyboard and Mouse which worked Fine the problem was gone. Please note we done a bench Test Leaving only His Hard drive Connected to the board, He is also running windows Xp Pro ... Thought it Be best to Use Same OS.

But as soon as i Took it Home and tried it again thinking it was ok... I was wrong.

@Scaminatrix : Board was Bought Brand New was in my Windows 7 Rig for a week then i decided to Upgrade My Cpu and Mobo. So I stuck my Old Board and Cpu in this pc (One with the problem)

@Aleksander : Yh Saw the post about this Board. No Doesent have CPU Unlock, USb is enabled in Bios. Erm I have Tried loads of Different Keyboards and Mouses, Trust ,Microsoft, Sumvision about 6 different keyboards mouses i own and about 4 i borrowed from some Friends and the only one that worked was the engineers Microsoft Keyboard and mouse.

@jakeman97 : The Pc In My Specs is My Main Rig (One Running W7) and the one with the problem is my Second Rig which is Running windows Xp and is only really Used for Video Editing and the Ocational Game with a m8t ...Lol

Finger hurt now from typing...LOl

 

is hardware OK (Win 7) for upgrade to windows 10

I think in one of the other PC with win 7 or win 8.1 I run media creators tools and in some step prompt/found graphics card not supported... for win 10. I didn't found alone reading specs of win 10, but the tool says me... after changed graphics card the tool said all OK and continued OK with upgrade... That I ask to reach this step in this current PC - win 7 - must be all OK for the upgrade? Or must continue to upgrade to show this?
and got to point

• UPGRADE this PC now
• Create media(DVD, USB stick, ISO)

is hardware OK (Win 7) for an upgrade to windows 10 for this PC???
