Multiple errors on newly-built PC

[un4td]

Thank you for looking.

OK. I'm thinking I have a bad motherboard or CPU. I have run a MemTest on each of my memory sticks and a Western Digital diagnostic test on my hard drive.

Here are the errors I have been getting often after I install/uninstall a program or the screen saver/welcome/lock screen comes on:

Application has generated an exception that could not be handled.

Buffer overrun detected. (upon opening a program)

Not enough system resources.

Bad Image. [file] is not a valid Windows image. (upon opening a program)

Windows can't create a shortcut here. (upon opening a program from the start menu)

There are no viruses on here. This computer is just a few days old and I have good security practices.

^ I doubt the above errors have anything to do with Mobo or CPU,...Such errors are mainly due to bad memory or HDDs or even on the software front...
Did you try reinstalling the OS ?

^ Re-Installed the OS from which disk ? Did you try with a different copy if it is accessible ?
