I own an Acer Aspire 5742G Laptop and lately I've been having some problems while trying to play some games and just running my laptop. The problem is that it lags/freezes sometime after some usage. Especially in games (a few minutes of ok gaming than lagging like hell). I think it has something to do with cooling. Although nothing happened to the laptop (neither mechanical shocks or exposure to dust) I think I'll take it to be cleaned the next few days...
I always kept it on my legs while playing and never had any problems for a hour or two... Now it overheats like hell after 5-10 minutes. I attached a picture just after a few minutes of mild usage (10-15). I understand that it's hotter now that spring is here but still...

So what I'm asking, what's your opinion on the problem? And what kind of stand/cooler do you recommend? And some info about positioning when cooling.
Thanks and have a nice day
EDIT: As a first look, a Cooler Master NotePal U3 looks nice. Although big for my laptop, it's good in the case I'll change it in the future with a bigger/better one.
First a good cleaning then a hdd check (HDTune), memory check (memtest86+), gpu check (furmark)...
What kind of results should I expect from those programs? What is an OK result and what is a NOT so OK result?
S.M.A.R.T. - everything should show OK (nothing yellow/red)
Error scan - each block should be green. Red blocks are damaged/bad sectors.
memtest86+ - test shall pass OK. You would get a warning or a red screen if your RAM is bad.
Furmark - Burn-In test -> you watch the screen while it's running.
If there are artifacts (texture corruption, colorfull pixels, ...) something is wrong with your GPU.
FurMark also shows your GPU temperature under load, check your maximum temperature.
DO NOT RUN FURMARK UNTIL YOUR LAPTOP IS CLEANED. There were cases of graphic card damage from overtemperature.
And I forgot to mention earlier, use OCCT or Prime95 to heavy-load your CPU and monitor the temperatures under load.
Use HWMonitor as a temperature monitor tool instead of SpeedFan. It's more detailed.
I know HWMonitor but it won't run on my laptop. I have no idea why. It has the same windows as my pc and works just fine. I even tried a few different ones just to get the same result. Anyway...
Thanks and I'll give it a try after the cleaning. Hope it will fix my problem. Or make it more workable...
EDIT: BTW, can FurMark make the laptop close? I read that on a few devices. Is that bad or it just does that? Just asking to be sure...
Make sure the vents are cleaned. Some disassembly might need to required to add new thermal, but don't do this under warranty. Might be better to have the Laptop serviced. You can also try updating bios and see that helps the fan speeds.
I already updated the BIOS version a few days ago. No visible improvement. I'm not cleaning it myself. I'm taking it to a service. I'll see what happens there
Back. Well the service man was amazed of how much dust he found inside. I have no idea how that much got inside but after a cleaning, oiling etc (full service crap) my laptop came back to life :D
It works just fine now. I'm guessing that should be a lesson for me to clean it more often.
I did every test and everything turned out nice. Thanks for the info/help
I'm not sure if you're able to, but if you can do it yourself in the future you can always pick up a can of air with a small nozzle/straw to help spray it out. Then just carefully dismantle it and spray it all out. good to hear you got it back to normal though!
I would but you can't imagine how hard it is to find a can of air in my zone :-?? Thanks anyway
You can find compressed air at many online retailers for a few dollars.
Not so common in romania. Believe me, I know.
If you have an air compressor or know someone with one(one with a tank), you could always regulate the airflow to a low PSI and use that to blow out your computer system. Just make sure there's a water trap on the line so its not spitting water out into your laptop.
Those air cans are not very good for your computer parts and they don't provide enough pressure. What you need is an strong air compressor. In the past I've used the blower-end of my shop-vac with a Micro Cleaning Kit. And I've used a leaf blower a few times, but overall the air compressor works best. :)
I know that. I used up until recent the back end of a vacuum for my desktop pc. I even used a compressor from a factory once and it was great. The laptop was trickier to open + it wen't against the warranty to open it myself. So for now, I'll just have to take it in service when it happens again.
I have a small air compressor I use to blow dust from all my electronic components. It's good practice to do it every other month.
Thanks Redney. I do dismantle my pc and clean it on a monthly basis but it's a little trickier with my laptop. A lot of small and fragile components all squeezed in together.
Don't blame you.. Laptops can be a puzzle.
