Windows 7 Home Premium x64 hangs randomly

My 3 year old Toshiba Qosmio x500 started hanging randomly so I did a fresh install using a Windows 7 Home Premium x64 OEM using my original serial no.

Still having random hangs. I use PC mainly for browsing nowadays. No heavy gameplay.

Only upgrades are additional 4Gb RAm and repalced HDD with SSD as previous one was busted.

In event viewer I got 19 Critical errors-Kernel power 41 as follows:

BugcheckCode 0
BugcheckParameter1 0x0
BugcheckParameter2 0x0
BugcheckParameter3 0x0
BugcheckParameter4 0x0
SleepInProgress true
PowerButtonTimestamp 130143938015870891

I have also run Memtest all night and run Furmark to burn test video card. All ok

Any ideas if it is hardware or software problem?

How close did you come to getting a perfect Clean Reinstall - Factory OEM Windows 7?

If you let WIn7 handle drivers and followed the other Best Practices in the tutorial, then go over your install with Troubleshooting Steps for Windows 7, otherwise I'd reinstall following the recommended steps.

I let Windows do its job during install without interfering....however when ready I had to get the wireless driver from Toshiba website as it was not recognised. Plus that I installed a bunch of other drivers from the Toshiba website including Turbo boost, Chipset utility, Intel management engine interface and Rapid storage technology driver. As for the video card I downloaded the driver from Nvidia website as the performance with the Windows driver was very poor.Should I do another fresh install and just install the wireless and Nvidia drivers and see how it goes?Thank you....

It depends upon what performance is like before importing the Toshiba OEM drivers which should be a last resort based on bad performance, i.e. Standard VGA placeholder driver given for Display with bad resolution, chipset functions poor or missing requiring Toshiba website chipset, etc.

Particularly important is how the IRST driver affected performance and whether your Toshiba offers an IRST setting in BIOS, possibly under SATA settings. If installed in IRST mode and hanging, I'd want to reinstall in AHCI mode, or vice versa.

HI Greg,

Thanks for your valuable advice.
Before I ran the Nvidia driver not even Windows movie maker was working and the Windows experience index was 1.8 if I recall correctly. Now it is 6.7.
At this point I will re-install strictly following your guidelines. I am just hoping it is not a hardware problem but I don't think this is the case.
Will keep you posted.

Hi Greg,
Decided to remove one of my 4Gb ram. First attempt still crashed and actually got 2 BSOD's. Replaced with the removed one and so far not even one hang......ran clean at least for 3 hours so far.
Will see in the following days.
Just wondering how Memtest did not report anything wrong if it is the faulty ram after all.

Tx,

Good to hear, Konrad. Keep us posted.

Be sure if you replace the bad RAM stick to spec it carefully so that it matches the specs and the other RAM.

Hi there,

Unfortunately my relief was short lived. Still having BSOD's. I also did another fresh clean install this time without installing any drivers apart the Realtek wireless driver and official Nvidia driver. I have also replaced back the original 2 x 2GB memory sticks originally installed on my laptop but still getting BSOD's. I have attached a screenshot of my last BSOD a couple of minutes ago. This happened while the pc was doing nothing actually.....looks like it is another hardware problem......about a year ago my youngest son threw up on the keyboard and had to replace the keyboard!!!!!!...maybe now some other parts are corroding slowly? System HDD was replaced a couple of months ago as pc center blamed the HDD for the BSOD's....obviously they where wrong.
Any ideas before I scrap this laptop? Don't feel like actually cost me an eye.

Hi Konrad -

What I would do at this point is simultaneously work through the Troubleshooting Steps for Windows 7
to go over your install thoroughly,

and post up the BSOD in our Crashes forum for expert analysis. Blue Screen of Death (BSOD) Posting Instructions - Windows 7 Forums

I'd also try different configurations with the RAM, one stick at a time, etc. to sort whether it might still be the problem. You've stress tested it overnight with memtest86? RAM - Test with Memtest86+
