Video freezes up to vertical lines or blue or white screen

My HP Pavilion 7520 was working fine for 6 months until:
on unexpected times the screen freezes up to vertical lines or a white or blue screen. The only way to bring it back is to hard reset the computer. Which brings me to the other problem; it's turning off by itself! It can go days with out doing it or it can happen everyday.

Clean the CPU cooler and everithing else from the dust!

Turn off,open the case, use air spray to clean.
(I use vacom cleaner and a small brush, but you risk your component if you do the same! I'm professional.)

Emachines t5274 vertical blue lines during startup/XP.

It looks like you've got two issues. If you tried a different monitor and it too have vertical blue lines your video card might be bad, but hold that thought. I'm thinking you need to reload the operating system because you can't boot all the way up which is the second issue.

Have you tried to boot up in Safe Mode and do a System Restore? Turn the computer off, then turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Select the Safe Mode option. When it boots, if it boots successfully things will look different in Safe Mode. The screen will be darker and icons bigger, but that's normal. If you get into the desktop successfully, click Start/Programs/Accessories/System Tools/System Restore. Select a restore point (date and time) that is before you started having problems. If the system tells you that you have no restore points, then you will have to either Reload the Operating System or do a System Recovery. By the way, System Restore does not lose your data, documents, music, pictures, videos, or programs unless the program was installed after the restore date. System Recovery LOSES EVERYTHING, it sets your system back to when you first purchased it.

Upgrades are usually troublesome as they leave bits of the old OS in odd places. It is best to do a clean install.
Choose your OS, either Vista or Win7. XP will not work!
Always download the latest drivers for the OS you are using from or it will keep hanging and be unreliable.
Hope this helps.

I think its the built in video not working right - HP s3700f

Yes it might be the built in video card but before replacing it just check out the Ram.It also can be an important factor.
If you do not find any problem in Ram then it is surely the Video card.

Please rate me if this solution works for you

Thanks......Have a great time.

HP Pavillion A1130N

Carefully give your monitor a quick slap on the top or side, NOT like you would hit an assailent, but more like you would hit your brother if you were kidding around with him. If you get a positive outcome from the slap, you have located your problem.
I'm assuming a CRT type of monitor. Probably the monitor has either a bad connection inside it or is simply dying from old age. Vertical Deflection grids supply voltage so that screen stays full top to bottom. If the output of the VDG is abnormal or missing, you will experience the horizontal line across the screen.. Unlikely to be the video card on the computer, generally speaking intermintency is not a common problem with video adapters, not to say that it couldn't happen,
