Y550p Freezes almost everytime (Windows 7 64 bit)

[ Edited ]

I have been searching for this annoying problem on this forum, but it seems like nobody has my problem, so I will be the first one to post.

 

Basically, my machine would completely freeze randomly with no BSOD at all while using it. My mouse wouldn't move and if there's any sound at the moment, it would stutter. To solve the problem, I would have to force shutdown and restart the computer. I have been trying to find the root of the problem to no success at all. I've had this problem long enough to estimate that I get these nasty freezes every 12 hours, but not always so. At first I thought it was the incompatibility of the 64 bit software and drivers since I am using Windows 7 64 bit, but when I reinstall the 32 bit version, the same thing happens, so I have weed that out as the main cause of the problem. I have also checked the DIVX video codec (only available in 32 bit) and I don't think that's the problem either. I have also checked the Event Viewer, and still no hints given there. So now I am left clueless as to what the root of the problem is and therefore I have turned to this Lenovo forum for help.

 

My laptop specifications:

 

Lenovo Ideapad Y550p

Windows 7 Ultimate 64 bit

4 GB RAM

Intel Core i7-720QM

 

Any hints regarding this problem is highly appreciated.

Sorry for may bad english. I have the same problem. My Y550P (Core I7 720QM) with new BIOS 5.04 can hangs in DOS(Live CD), LINUX (Live CD), Windows 7 64bit in different time.

 

Everest (Burn CPU) + FURMARK 1.8.0 = 3h. - no hangs (t CPU=89, GPU=96 - very bad cooling!!!)

Memtes 2.11 (Linux Live CD)=6h. - no hangs

 

But, my Y550P can hangs in IE (5min) from Win7 64.

 

I think, this problem in BIOS 5.04 :smileysad:

Even before I upgraded to the BIOS 5.04, I already have this nasty issue. I don't think the BIOS is the root cause, but then you never know.

I just hope I don't have to send my machine in for a motherboard replacement again. Otherwise, this would have been the second machine from Lenovo that require servicing in such a short time since purchase.

Re: Y550p Freezes almost every 12 hours (Windows 7 Ultimate 64 bit)

I just had 3 more system crashes and I realized something I didn't noticed before. I was chatting with a friend and playing music, and when the nasty freeze occured, I noticed that I can still chat with my friend and the music is still playing, but the display completed freezed and my mouse and keyboard are not responding at all.

 

Looks like this is a display and control driver issue, but still no solution so far. Any help from anyone here is highly appreciated.

I am trying to reproduce the problem so that I can take the machine in for warranty service. Mishanchik, any luck on that?

Alright, I was able to reproduce the problem by running an intensive BurnInTest which stresses the hardware and I got the same nasty freeze. 

 

I had this problem before with my Thinkpad T61p with just 2GB of RAM and I suspect the motherboard is to blame. This happened way back in 2007 and I cannot believe Lenovo made the same mistake after 3 years.

 

Try this on your machine:

 

Download  BurnInTest and test all components of your hardware at the max (100). If your system freezes, then I believe we have the same problem.
