This weekend I got home and set my laptop up, started playing a game, and it froze up on me. I didn't think too much of it, restarted, went on youtube, and a few videos later, it hung up again. This time however, it resumed after a while of stuttering. Since then I have had three other hangups just this weekend that I had to restart from. I was looking through my explorer and noticed that under my System tab it showed my RAM as 4GB (3GB usable) so I started looking into this. I never remember this being this way. Under my resource manager, it is showing 1025mb reserved for hardware, which seems very strange. My graphics card is dedicated, so I have no clue what would be causing this.

So my computer is using approx 1/2 of my RAM all the time just doing basic tasks, and it freezes up quite often if i start doing memory intensive things like classwork.
Googling the issue showed a few people talking about reformatting their computers or remapping their memory in bios. I did reformat a few weeks ago, but I don't know that the issue stems from there. There is no memory mapping option in my bios, so that's out. I actually decided to reformat again today to see if it helped, and this time I completely reset my harddrive instead of just reinstalling windows, but it still didn't fix the issue.

I've run windows memory diagnostic, and it says there is no issue. Memtest86 I had running for about 8 hours last night, no errors reported but it lists my memory as 3017MB, not 4096MB like it should be..

If one of my RAM cards were dead, would it show up in my System tab? Why would that cause it to be under reserved? What else could be the cause here? Doubting it's software related at this point since I just completely reformatted my computer.

Win 7 64,
ASUS N70SV laptop
Intel Core Duo 2.66GHZ T9550
nvidia 130M

Edit: Suppose it may be worth something to mention the reinstalling of windows a few weeks back was due to multiple blue screens messing up my registry.

Hi -
It seems that you are OK with playing a bit with your computer from the post.
I would prefer it if you could run Memtest86 with only one stick of RAM installed, and then repeat it.

>>it lists my memory as 3017MB, not 4096MB like it should be.. << Do you mean there are 4 sticks of RAM.
If one stick is not regestering this will find it, and you can then replace it.
Single stick tests should not take quite as long, since a bad one will show up quicker.

Regards -
