Resolved Question

My computer has been getting slower and slower over time

At first I could play Overwatch with music or a video on in the background, then Overwatch started to crash after playing for awhile with HD videos on at the same time, with memory overload errors. I just put the videos on to low quality and it fixed it for awhile.

Later it started crashing again with a graphics card error, and I could no longer play with videos in the background.

Now I can't play at all, and my browser crashes when I have too many tabs open.

So, my question is, what do I need to do to get my computer back to running like it was before? Is the hardware busted or did some update screw me over? I don't mind buying a new Graphics card or RAM or w/e, but I don't want to replace more than I need to.

Some specs:
OS: Windows 10 home
GPU: AMD Radeon 7700 Series
CPU: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz, 3401 Mhz, 4 Core(s), 8 Logical Processor(s)
Installed Physical Memory (RAM) 8.00 GB
Total Physical Memory 7.98 GB
Available Physical Memory 4.23 GB

If you need more info let me know.

Thanks in advance!

How are you keeping up with maintenance?

And don't tell me it's not heat. We must keep things clean and cool. The 7700 is no spring chicken so let's hear about cleaning and your last fan test.

Oh boy, is that really it?

I honestly can't remember doing any PHYSICAL maintenance on my machine... ever. Now I feel really bad for the poor ol' girl.

I haven't looked inside in awhile but it's really bad.

I'll clean it out soon and do a fan test, then get back to you on how it's doing, thanks for the heads up my friend, I appreciate it, for some reason it never occurred to me that that could be the issue.

Let's hope so.

There are plenty of YouTubes on PC cleaning. Mostly it's about being gentle and not going beyond your comfort zone.

There may be other issues to take care of but this is something to knock off the list first.

It seems to be working!

In reply to: Let's hope so.

Don't get me wrong, there are DEFINITELY other issues with my PC, though all I want is for it to be able to do the same things it's always been able to do.

And it seems to be doing them right after cleaning! But God, there were cobwebs in there my friend. I had to wear a dust mask it was so bad. It's actually noticeably louder now too, which I think is a good sign?

Anyways, thanks so much for the help R.Proffitt, you really nailed the issue on the head! I'll be sure to bother your forums with any other silly issues I may have in the future.

The increase in noise

In reply to: It seems to be working!

Is easy to explain. If it was dusty enough it works to deaden sound.

Glad it was the usual, Sometimes it's not and we move to other areas.
