I've bought a laptop about 3 years ago, and 1 year ago it started having problems until it completely failed. It started to shut off randomly and eventually didn't even boot anymore. I recently gave it another attempt and tried to replace the hard drive with a new SSD. I also installed 4GB new ram (8GB now). To my surprise, it suddenly worked again.
However, now I'm having new problems:
The computer now sometimes suddenly restarts, giving me the Following Event:
Event 41 Kernel-Power
What most often happens is that when I start up the computer it SOMETIMES automatically restarts right after booting windows. It's always at the point where the windows logo has appeared and where windows has seemingly loaded, right before the user name and password box normally appears. Then the next boot often works but usually (but not always) takes much longer than normal (my new SSD usually takes 3 seconds between showing the windows logo and showing the user name and password box, but when it automatically restarts after such a boot failure it takes about 30 seconds).
I never get any error messages, and I''ve never seen the BSOD appear. Is there a way to delve deeper into the cause of this by finding more detailed info than given by event 41 at the event viewer? I already tried unchecking the option "don't restart" after system failure, but this doesn't give me the BSOD when the system fails.
I've downloaded Speccy and seen that the CPU usually is between 55 and 65 degrees celcius with normal use. I ran Intel processor diagnostic tool which shows no problems.
However the weird thing is this:
I've had the laptop with SSD installed now for 4 days, and every single day, it did this the first time I booted the laptop in the morning when it seems to me to be at its coolest which is the opposite of what I'd expect. But I've restarted and shut down and booted the laptop numerous times during these days without a problem.
I've also played crysis 2 on it just to test. it then moves to 93-98 degrees celcius, and it shut off once while doing this. It has also done so at least once while it was on, but this definately happens less frequently than during booting.
I have two questions:
1. The obvious: I've looked online at what this problem could be and how to solve it, and although the possibility of overheating being the cause is suggested by the crysis-shutdown, it is not supported by the fact that it also hapens first boot in the morning. So what could the cause be, and how do I solve it?
I've considered the possibility of power supply not being sufficient, but it would seem to me that if this were the case, it would shutdown more frequently and more immediately after starting crysis (rather than 10 minutes into the game), but I don't know much about this.
2. If it cannot be solved completely: How can I makethe problem manageable? I don't want to play games on it (crysis was just to test), I just want to have a reliable laptop for word, excel, photoshop and internet and such, that doesn't fail on me right before a college deadline. Is it safe for my laptop to keep this problem unsolved and simply live with the fact that bootup effectively takes longer? or will this progressively destroy my computer/SSD/CPU making it fail after a while, if kept unsolved?
Something else that may be important: after installing windows 7 on my new SSD, it didn't have the drivers yet, so I used DRP (Driverpack solutions) to install the drivers on my computer. I didn't accept to install any programs.
A lot of thanks in advance!
Some additional info:
I have my power supply maximum cpu setting set to max 75%.
Here are my specs:
Model: Acer Aspire 5742G (Motherboard version V1.24)
BIOS: V1.24OS: Windows 7 64 bit SP1
CPU: Intel i5 450M, 2.4 Ghz (2 cores, 4 threads)
RAM: 2x Samsung PC3-10700 DDR3. (The newly installed RAM chip has 1 extra JEDEC thingy, but they seem to be both running at JEDEC 3, for which they have identical timings and voltage).
Graphics card: Nvidia Geforce GT 540M
