Browse All TopicsHello,
Since last year my laptop has been plagued with errors. I first noticed this when the computer would go into sleep mode, when coming out of sleep mode the screen would stay black and never come on so i had to power off. Then on boot, it would fail with the BSOD and no way could i get onto windows without rolling back, in safemode it would stop on, crcdsk then the BSOD would happen.
I go out of the routine of sleep mode and started using hibernation which worked a treat. Anyway if the computer crashes or if i turn the power off by holding the power on, upon restart i would have the same problem as with the sleep mode, when booting the BSOD would appear.
Its just happened now but when i shut down the laptop properly. When i booted it it failed on the blue screen of death, with HARD ERROR which was a new error. I done a memory check and it said it would show the results when windows logs in. I didn't start so i don't know if the memory is duff or not. I bought the memory last year from ebay but didnt think it would be that, i bought some more last week, some crucial 2gb. I've just removed the old memory i bought and i started the laptop with no problem, even though before i removed the memory i couldn't get it to start.
I'm just wondering if this is a common problem and if it was the memory or a coincidence.
Thanks in advance.

Also boot from a bootdisk and run a: chkdsk /r
To rule out any defects on the hard drive and since you had a few crashes, it will clean up any minor file corruptions caused by improper shutdowns.
Let me add to jhyjesla wonderful comment, when using memtest you want to do it in this method if you have more than one memory stick:
Remove all memory sticks and just add one to the computer. Boot from the memtest cd and run a scan on it, Wait about 2-3 hours on each (maybe more) and see if you get any errors.
If not, shut down, remove stick, place other one, repeat scan.
If you have multiple sticks, memtest can detect errors but it won't tell you which ram module it is. So to save time and headaches, scan each one independently. Memtest recommends this method, they might have other tips, so look into their documentation.
Are you running Vista? There was a crcdsk.sys issue in some Vista. Let us know.
To add to my last comment, take a quick look at some of these random links:

You'll see users with the same crcdsk error in Vista. Some updated their bios and resolved, some removed ram and worked, some changed sata to compatibility mode in bios and worked. If you google crcdsk.sys vista, you'll see numerous results.
My advice if you changed the ram to the new crucial, and no problems, get rid of the old ram and buy identical ram to the new one. Ram is inexpensive nowadays. Perhaps the older one installed is defective, maybe ecc or r ram not fully compatible. Keep in mind 32bit versions of Vista are only limited to 4gb of ram. Anything more you buy, Vista will only see 4gb. To see anything above that, you'll want 64bit version of Vista.
Don't forget to run a chkdsk to clean up any corruption improper shutdown may have caused.
Thank you very must im just running memtest on my older ram, ran one test for 30 min on the new ram and showed no errors, i'll keep this one running for a few hours as i suspect it is this ram causing the problem. Im on my fathers desktop at the moment whilst checking my laptop.
I'll take a look at the links you just added.
Thanks again
Still tersting the memory and its stuck on this:

That also shows a memory fault. A video of this fault can be found here:

Hope this helps. Could theis be the causes of the crashes and the problem with coming out of sleep.

Replace the ram, any signs of error along with 'weird' symptoms/crashes indicates possible ram errors which is now confirmed.
Ram is really cheap nowadays. Get some at newegg.com. Do your best and stay with a brand, like corsair, kingston, etc. 1. You'll know the quality is good and 2. If any problems you can go on their website and start a RMA request to replace the ram for free.
If I were you, I'll stick with 2 matching pairs of ram, 2gb each. Mix/Match ram sometimes causes weird symptoms or can downgrade the speed if you buy newer ram. Example, 1yr ago you purchased DDR 2100 ram. Tomorrow you buy a new 2gb DDR 4200 ram, which is rated faster. The system will set the ram speed to the lowest ram chip speed. Keeping both at 2100.
Also some systems offers advantages like dual channel, which requires matching speed/ram, to get hold of this benefit.

you can always download memtest86 from memtest.org and create a boot disk and run it against the new RAM as well as the old.
