Hardware issue

[Anderzzon]

So my computer is starting to act up. When I play games like Fallout NV, League of Legends and CoD: Black Ops. the screen sometimes dies, though the sound is still there for some time, then the sound goes into super slow-mo. After that I just switch it off and turn it back on and then it works fine. I am pretty sure it's a heat problem since if I turn off the shadows in LoL completely it works like a charm. So, two-part question, is my theory a valid one? If so: What component is most likely to be the one overheating? CPU or GPU (ohh please god let it be the GPU...).

I've vacuumed the dust filters and all that so the fans aren't blocked.

Thanks in advance!

You can always use a benchmarking program to test the heat of you're processor, GPU etc. and give us some more info, try speedfan and tell us what you're temperatures are outside and inside gaming.

Been using speedfan for years and years. Anyways it's about 35-40 outside and 60 tops inside, and that is really low, I know. So I have no idea what's wrong. I assumed it was the heat since last time I had this type of issue it was. Well the issue isn't exactly the same, otherwise I wouldn't be asking.

If it's the motherboard (AGAIN!) I swear I'll... *mumbles*... with a melon... *mumbles*... and a fork through the... *mumbles*

If the speeds are low try using furmark to benchtest you're GPU, if it's fine than it's one less thing to worry about ^^

Judging by the sound my computer makes when it's on the fans aren't too slow hehe. Also I have a fanless cooler for my CPU, which works really fine. So we are sorta back to square one?

It happened again yesterday when I was playing black ops, I can pro long it by quitting the matches in intermission and fiddle about with my classes and such before starting a new game, which, to me, sounds like the heat once more. But I could be wrong. This computer has worked so well for so long that I've lost my touch completely when it comes to indentifying and fixing hardware problems.

It could be anything then really xD

You can try using Memtest to check for faulty ram.
You can try a windows reinstall (or whatever OS you're using).
You can check for bad sectors on the hard disk.

Although mostly this would show a black screen, but i think the freezing in game like that is mostly the Graphics Card dying out ^^

That's what it sounds like to me too. If it is it'll make me a very happy man considering I've been thinking about replacing it for a while.

I'll try to get a hold of another GPU and test it out.

Try borrowing some parts from other pc and try one by one.
