i'm having a problem with my laptop. i think it may be overheating but i can't tell for sure. it started about a week ago, my laptop just started crashing at random times, no blue screens, nothing in event viewer, so i downloaded speedfan to keep an eye on the temps... i noticed the temps were getting up to 50C+ so i decided to take off the back covers, clean out all the dust and replace the thermal paste, see if it would help. the cpu and gpu run between 35-45C but the harddrive is still always hanging on 50C and higher. there's nothing running in the background, hdd light doesnt flicker, prefmon shows barely any activity. but i just noticed something weird, if it IS overheating... it doesnt crash till i move the laptop. as in, i pick it up or nudge it trying to tilt the screen... its fine sitting there till i touch it. i have NO idea what could be causing this and now its driving me mad trying to figure it out... if anybody could help me solve this id REALLY appreciate it i have an acer aspire 5630 running windows vista. 2gb ram, intel duo 1.8ghz, 160gb hdd, its dual booted with ubuntu, im using it right now to see if maybe its just windows causing this to happen?

A loose connection somewhere is possible. Check the battery, could be that. I suppose your fan could give out when you move it and cause overheating also? You didn't really convince me that it was an overheating issue though.

would it really be the battery, even if its plugged in? the battery doesn't get hot at all if thats what you mean. when the temps are lower it doesn't seem to happen, once they're around 50C it starts crashing. i've done virus scans using avg, avast, and scanned with malwarebytes and they found nothing. i don't know what else it could be :(

I more meant that it is possible that the battery has a loose connections (googled and that was a BSOD issue for someone else). It sounds like you have a loose connection somewhere if it is crashing when you move it. Google also suggested that it could be an issue with the memory seating.

 

I don't really see why it would be affected by temperatures and 50C really isn't that hot. Based on your symptoms though if the fan stopped for a bit, the laptop could suddenly overheat and freeze... I suppose. 

 

First thing is to try to eliminate things you can rule out: remove battery, does it still happen? Reseat ram, does it still happen? Shake laptop, does it happen regardless of temperature (don't actually do this one -- unless you don't actually have a mechanical hdd or anything you could break by lightly shaking it), etc.

Do obvious things first, then try new thermal paste. Works wonders.

i've been trying to make it happen by wiggling the screen, pushing on the battery, and pressing on the corners near the hindges where the case is a little loose, nothings happened so far. im gonna try reseating the ram tomorrow. hopefully that'll work. i checked around on google, somebody said they disabled aero and it worked for them. im just really hoping its something i can fix, i dont have money for another laptop right now :'(

tried reseating the ram and hdd, but still getting the same problem. this time i had the laptop on a flat surface. it crashed and i got a beep code. 1 long 2 short, then a minute after just 2 short. i looked it up and it said a graphical error. the 2 short was for not being able to access bios to show the error? when the computer rebooted, the date and time were set to june 25th 2005. the time was 1:00 AM... this never happened with the other previous crashes.

Get a new CMOS battery. It's losing info, probably why its crashing.

That isn't true. It wouldn't crash if the battery was bad. It would run -- albeit with defaults.

What type of bios is this or what is your computer model? Errors could be different depending on the bios type (award/phoenix/ami/etc). I see for phoenix that 2 short beeps could mean a CMOS error which is possible considering your date reset. Second, 1 long and 2 short is a video card error for a lot of different bioses, but not necessarily for all.

Could be a setting in BIOS that was reset, causing this very problem.

it's be very unlikely that default settings in the bios would cause crashes (it isn't like defaults would OC or change voltages...)

Unlikely, yes, but in any situation, it can be. I'm not saying overclock, I'm saying like AHCI/IDE.

I have Phoenix bios. Not sure which version. I'll try changing out the battery since I have to reset CMOS to get passed the password it's asking me for (it had a password by default, I didn't set one) I'll try reconnecting all cables I come across in the process. But if this still doesn't solve the problem what else would you guys suggest?

 

 

EDIT:

i just realized, is there a possiblity that its the IRQs? i can post what everything is assigned to. i know its usually set up automatically to avoid this kinda thing but its a possibilty, no?

Luck and godspeed :-) Phoenix is the bios that has the error code with 2 beeps on cmos error so I'd bet money that it lines up with your cmos resetting. I think you probably have a real hardware issue at this point if disconnecting/reconnecting things doesn't work. The one other thing I can suggest is trying to see if other people with your laptop model have the same issue. I once had a HP laptop with a motherboard that had a high chance of a defect that would cause the screen to stop turning on 9/10 times on boot. It was a nvidia chipset issue and HP refused to acknowledge it or fix it even though nvidia acknowledged the issue. Basically though, all of those models would eventually fail in the same manner.

 

The best you can do is trying to trace it to a particular component as you have been trying. Did you try to check if the issue occurs with the battery disconnected? or the power supply disconnected? I.e. to see if one or the other could be causing the issue? The reason I ask now is that perhaps it isn't high temperatures, but high load and fluctuations in the supply voltage/current that is causing the issues. A surge/sag of some sort could even cause the type of issues you are seeing with cmos being reset. I've had my dell 3-4 times tell me the real time clock isn't working and refuse to boot until I pull my battery out as if some kind of power issue occurred.

A bad bios battery isn't going to cause it to crash.

Sounds like the CPU or GFX chip is over-heating.
