Desktop switching to black every few seconds

Oct 28, 2016 1:14PM PDT


Since a month or so I have a problem with my desktop of my Asus laptop, especially when I play a game it's about every 2 seconds that my desktop turns black for about 0.5 second. Very annoying. But when I'm not gaming it doesn't happen that often.

I think this started when I lent another charger, which wasn't from my Asus but another Asus laptop.

Any help for this? Thanks in advance!

A few things.
Oct 28, 2016 1:17PM PDT

1. Full make, model and age of the laptop or desktop.
2. Are you using your canned air on schedule? Makers rarely advise this as it could make machines last longer and have less issues.

Thanks for your quick response,

I don't know what you mean by 'full make', but here some information,

1. Asus F751M, age about 2/3 years
2. No I don't use canned air

1. That's good info.

2. It's time to start. Start with daily for a week, weekly for a month and back to 1st of the month.

Alright thanks, but could using another charger also be the cause of this?

And easier to fix. Use the right charger.

I used the different charger for a few times as I lost my own charger back then. Since a month I only use my own charger but that didn't solve the problem. The weird thing is that the black switching doesn't happen all the time but mainly when I'm playing a game, is there some explanation for this or another probable solution?

Since the machine was not getting the usual cleaning.

I worry that I was not firm enough about this. Tell me how firm I must be without upsetting you.

There's a heat problem on laptops
Oct 28, 2016 3:16PM PDT

Asus and HP seem to be the biggest offenders. It involves shared heatsink material at times between the CPU and the nearby GPU. The safer laptops use totally separate heatsinks to avoid the problem of heat bleed from CPU coming to the GPU. What this is causing is for the solder on some graphics chips to melt an some contacts on the graphics chips and motherboard to fail. It can manifest itself as various problems and eventually total loss of signal. Just google "HP reflow Nvidia" to get plenty of information on just one of these laptops.
