PC screen getting all fuzzy

[hpluls]

Today my dad encountered this problem on our PC (specs in my profile). After some time, the screen gets all fuzzy, the PC freezes and needs to be restarted. What might be causing this? My dad said it started occuring directly after installing an update for Avast Free Antivirus. To me, it looks more like a video card issue, but I just want to make sure. Here are some photos of the screen:

More than likely a failing GPU. Or possibly the PSU because the older they get the less power they can produce so it may not be powerful enough anymore.

 

Could be caused by the CPU, motherboard or RAM though.

My guess is GPU, that's happened to me dozens of times and always been GPU

you've pretty much counted all the components of pc :P , try reformatting or if you have an on-board gpu on your motherboard take out the gpu and have another go.

I'd say GPU, you could try updating the drivers, if that doesn't work then it's probably time for a new graphics card.

90% of the time the GPU just isn't pressed in to the motherboard enough, check that before you spend money on a new one

Install an app that tells you the system (GPU) temperature - it might be overheating.

Only because it could be all of those components. It's hard to say what the problem is if I don't have the computer in front of me.

Thanks guys, I'll do what you've suggested and see if it helps.

I've unplugged it and plugged it back into the mobo, cleaned the dust out of it, and updated the drivers... none of this helped. Guess the only solution now is a new card. Since the PC is no longer used for gaming, I'm just looking for something basic. Anyone got any experience with the GeForce 210 or something within its price range?

this is kind of good for its price

Asus 512MB Radeon HD 5450 Silent DDR2 Low profile: Amazon.co.uk: Computers Accessories

Thanks. I've actually ordered a GeForce GTX 550 Ti 2GB for a good price, just in case I need some more power someday.

lol alright then :P

And is your power supply good enough for it? I hope it is p

Installed the new card a few days ago, it works like a charm.
