Vertical lines distort screen at startup

Lenovo Ideacentre k230 - 53593gu - intel...

Specs: Windows XP
I push the power button. The lenovo screen appears on screen witch is normal then the computer freezes for about 10 sec. After that 10 seconds the screen shows several vertical lines witch completely distorts the image. The computer does not load past that point. Entering the bios is impossible. I checked the mobo for bulged or leaking capacitors but found none. I suspect either a failed integrated video and/or an entire trashed mobo. Tested the PSU and it's working normal as well as the ram and cpu. Looking for a second or third opinion. Thanks!

How did you test the RAM and CPU? Were you able to run memtest86?

It definitely sounds like garbage RAM to me. Two reasons:
-Fails to load Windows. Sounds like it's not even fully POSTing.
-Lines/distortion appearing on screen before the Windows display drivers even load is usually caused by bad video memory. Integrated graphics use a portion of system RAM as video memory.

Thanks for shooting down my plane full of confidence jackbomb. I switched out the RAM with a known good RAM stick. The computer gave a delay on "verifying boot volume....."
Then booted to Windows XP pro sp3 BUT it freezes on "Preparing network connections" while it is loading the login screen. After about 1 min of being frozen the screen distorts with vertical lines. Hummm. Can I write this off as bad integrated video? Light it on fire, throw it in the paper shredder, grind it into dust add water and use it as war paint! Hahaha Just kidding.... but seriously.
