That sounds like you have mis-matched RAM which can cause problems.
I would run memtest from a bootable CD/USB to see if there are any errors.
You can test each RAM stick individually, and test with both installed, it will take a long time.

The bsod issue is fixed!! after i removed the 1gb stick and kept only the 2gb, the computer ran flawlessly!
so the 1gb stick was d culprit!! as of now!

@Addram: Would this ram work??

Kingston ValueRAM DDR2 2 GB Laptop DRAM (KTH-ZD8000B/2G) - Kingston : Flipkart.com

Awesome, now lets see if it stays that way for 24 hours

As long as the stick you`ve found is the same size, speed and has the same timings it should work fine with your current stick.

But I can not stress enough how important it is to buy a 2 x 2 GB kit instead of buying another single stick, maybe someday you can do that.

I`m happy you are making some progress. Keep your fingers crossed

Hey, here is the snip of device manager!
Should i download intel drivers and try to install them or should i keep these default microsoft drivers? But one problem is that there ms drivers would not let me play any game at good frame rate as compared to installing latest intel drivers for better performance!

EDIT* - i searched for the same ram which i have by noting down the model number but the same ram was not available. i saw many others which look same like the one which i have (200 pin , sodimm)

And also the ram which i have is 800mhz. So if im buying any ram it should just match 800 mhz, 200 pin and SO-DIMM rite? doesn't have to be the same model?

I would just right click on it and choose to update the driver, leave well enough alone.

So it`s only showing 1 Graphics adapter now ? That`s awesome !!

You may have 800 MHz ram, but what speed is it running at, the specs only say it supports 667.

No it does not have to be the same model.

Install CPU`z and post a snip of the memory tab please.

CPU-Z | Softwares | CPUID

Example.

Also, what is the speed of the 1 GB stick you removed ? What does it say on it`s label ?

Not 1 page I can find says it can run 800 MHz memory, it may somehow have gotten installed, but every spec sheet I find says it uses this type of memory.

DDR2-667/PC2-5300

Did you run the Crucial scanner on it yet ? That will give us some more clues.

Crucial.com - Guaranteed-compatible upgrades memory and storage for your Acer computer

If it gives you no more problems running that 2 GB 800 MHz stick, then by all means by another one of the same exact thing. Once again it doesn`t have to be from the same company.

Your PC may run just fine with 800 MHz memory, but chances are it`s still only running at 667 MHz. And the point I`m trying to make about that is this, say one day you do go out and finally buy that matched set of 2 x 2 GB sticks, now let`s say the 667 MHz set costs $20 less then the 800 MHz set, now knowing that your memory will only run at 667 MHz, which set are you going to buy ? Of course you`d buy the cheaper set.

After you post the snip of CPU`z we can see the actual speed your memory is running at.

OK, just as I suspected your memory is only running at 667 MHz

332.4 x 2 = 664.8 MHz because DDR means double data rate, but cpu-z only shows the single data rate.

So the 800 MHz stick is working fine, but it`s only running at 667 MHz, just as the specs say. So get the other 800 MHz stick you found and hope for the best, it should work fine.


You still have not told me what the 1 GB stick speed says, you have to be much quicker with your responses, I`m gettin real tired here
