Computer can get very laggy at times

wubbzy · Oct 2, 2018

Hey guys, I just want to ask why my computer gets a lot of fps drops. I usually only play Overwatch and League of Legends, and LoL runs fine at high settings but Overwatch becomes very laggy.
It's not just games as well, sometimes I'm just browsing the web and my computer begins to stutters for a while.

Cpu: Intel I5 4690 - 3.5GHz
Ram: 4gigs (had 8 but the other stick isn't working anymore :/)
GPU: Gigabyte Radeon 7970
PSU: VS550 — 550 Watt Power Supply

I'm not tech-savvy, so I don't understand too much.
Thank you.

How old is the PSU? You didn't mention the OS you're on. Have you tried uninstalling and reinstalling your GPU drivers with the latest or last known stable version?

Lutfij :

I believe the PSU is roughly 4 years old and I'm on windows 10. I am also currently reinstalling my GPU drivers.

Best Answer: You are only using 4gb of system memory. That is the reason why.

Peter Martin · Oct 2, 2018

agree. 4gb is the bare MINIMUM for even just windows 10, not including anything else that runs, games, apps, whatever. 4 isn't enough. 8GB is the new minimum, 16 preferred for gaming.

my notebook was horrible with only 4gb ram. once up to 8, windows was snappy and apps worked fine.

after you add the ram back in. run hdtune check for any hard drive warnings and run the vendor hd test tools.

smorizio :

When I add the other ram stick back, my computer keeps beeping and wont turn on.

Peter Martin · Oct 2, 2018

so you have found your bad ram then, you need another stick dude.

wubbzy · Oct 2, 2018

Peter Martin :

Yeah i guess i would need to add a extra stick in. Only reason why i didn't is because i don't understand too much about computer and whether or not 4g of ram can have such an effect on the performance.

Do you guys know if this ram stick is compatible with my mother board?

Motherboard: Gigabyte H81M-S2H

Even if you get the exact same stick that you have, same speeds or specs, RAM is not guaranteed to work outside of buying it in matched sets of say, 2 or 4 sticks. I would probably suggest 2 new sticks of compatible ram. You can use Crucial.com to find compatible RAM.

here, you can cross reference those or just buy a set

First see if the known good memory stick works in the dim slot of the other one. This might not be a ram issue.

SgtScream :

So i put the working ram in the other slot and it didn't turn on.
I took the working ram stick out and put the other one that i took out a couple of weeks ago in the slot of the working ram (still didn't turn on)
I put the same ram in the other slot and it didn't turn on again.
I put back the ram that was originally powering up my computer the last few weeks back into the original slot and my computer powered up now.

So I'm guessing the other stick of the ram is broken and the slot for the ram is broken.
If that's the case, can anyone recommend me a new motherboard? (unless I'm able to get the slot fixed)
Thank you.

as the parts are new rma the ram and the mb most mb vendors have warranty checkers on there web page.

Good job Wubbzy. You are on the right track. You can find some new and used motherboards on ebay. Just get a h97 motherboard that fits your case.

Did you try swapping ram sticks?
Put the known good ram stick into the suspected defective dim slot.
Put the suspected faulty ram stick into the known good dim slot.

wubbzy · Oct 3, 2018

SgtScream :

Yeah i did. I put the good ram stick in slot 1 and it powered on, then put it in slot 2 but my computer didn't power on from that
I put the ram stick that i suspect was broken in slot 1 first, and my comp didnt turn on, and then slot 2 and my comp still didn't turn on.
I put both in and switched their places and still didn't turn on
So right now im just running on 1 - 4gb ram
