I've been able to disregard this problem until recently, especially considering all of the tests I've done on it.

I bought an Asus laptop (K53SV-XR1) around a year ago now and it's been giving me mixed performances. On one hand, it's a great laptop overall, but it's had its share of follies. Only a few short months after buying it, I was under the impression that one of the memory sticks was bad, so I bought a replacement. It seemed like it was fixed, but I was eventually greeted with this problem: randomly (and I mean really, really randomly,) my computer would just seize up. It would make a little crackle sound (maybe a pop, it doesn't make it every time), my computer's display becomes a garbled mess of rectangles, and it is totally unresponsive. I've included a pic to illustrate it.

I've recently downloaded a GPU/CPU temp monitor, but from what I can tell, nothing is getting overheated when the problem happens. Again, I could be playing a game, watching a youtube movie, or even typing up a paper. Some days I never have it happen, but yesterday it happened five times within a 8 hour period.

Not sure if this points directly to a GPU problem (hopefully not), but it is only a year old. I feel as though I shouldn't be experience component failure this early.

(If it's needed, I've got an Nvidia Geforce GT 540M in this thing.)

I should also mention that occasionally, there is a buzzing accompanied with the crash, although it's not usually a constant buzzing. It may be that if sound was playing right before the crash, it turns into the buzzing; if not, it's silent. I can't say for certain, but I'm fairly sure that's the pattern.

Thanks for any info.

-Nate

My first thought is (unfortunately) a GPU problem. Have you tried hooking an external monitor up to it? that could eliminate the possibilities of the problem being in the screen/inverter/cables. Update your graphics card driver.

I'd also run memtest overnight.

Thanks, Fruta, I appreciate the suggestions.

Unfortunately, I very regularly use this laptop plugged in (via HDMI) to a small TV. Since the same thing happens on the TV, I know the problem isn't simply limited to the cable/display. I'll try to do a clean uninstall/reinstall of nvidia drivers, as well as let Memtest run throughout tonight/tomorrow.

How difficult are GPUs to replace in laptops? I'm quite alright with desktops, but I know that laptops can be an entirely different breed.

Most laptops have GPUs integrated into the motherboard as a chip so replacing the GPU means replacing the motherboard, although in looking at the GeForce GT 540M chip it may be replaceable. Whether that makes economic sense depends on the cost of the chip and labour to replace it.

I have to wonder why you didn't get a warranty replacement when your problems first started occuring. Is it too late now?

I haven't had the crashing problem since updating my graphics card driver (still don't know why it chose to this time and not the numerous times before...)

Anyway, Asus claimed that they had a 1-year warranty for accidental damage, which I couldn't claim when the problem first started happening because it was the day before leaving for college (freshman engineers rely on laptops pretty religiously, apparently). So I didn't have time to take up the replacement offer for fear of being out of a laptop for a few weeks.

Oddly enough, when we finally had time to investigate a separate issue (power input jack was loose), we saw that the "warranty void if broken" seal was already broken. Which was odd because it was a new laptop when I bought it (I thought.) So who knows, maybe I was sold a refurb without being told. Not exactly the most honest thing to have happen, but it still works (relatively) well, so I can't complain.

Hopefully I've seen the last of the crashing problems...

hello, this system is propably still under warranty...

You could return it, your graphics card is heating itself up too high... try to go to a tech and have it blown out first, after that...

if it still is the problme, please send it back to asus, these things normally had 2 year warranty ((in my store)) so it should be fine
