high memory usage

first off im new to posting on here and id like to say hello to everyone :)

lately ive been getting weird spikes on my computer, not on the internet but just my computer itself seems slow. it seems that my physical memory is always around 50% - 60% but my cpu is 0%. i also noticed that its running 60-70 processes, not at startup, but when im just at average computer use. i took a screen shot of my task manager and my resource manager:

i also have hijackthis if needed. i was concerned about such high use of the "hardware reserved", 2089mb...seems high to me? ive seen other posts on here with half of that and my friend has 3mb hardware reserved. sorry for the wall of text and thanks for help in advance.

hey so i checked my current ram to see how much i had installed and it showed 4gig but (1.96 in use). so i turned off my computer and took out a stick of ram, restarted, 2.00 gigs showed up. tried the other stick by itself also and it showed 2.00 also. so i tried them both together again dual channel, the same way i had it before..it gave me some crazy beeps as if i installed it wrong, then restarted by itself and it worked properly? does this mean that the mother board could be dying, i have no idea.

haha so i dont know what happened exactly but that was the problem and its working now back at 4.00 and feels much smoother like it used to. here is a screen shot:

not sure if its necessary now but as for specs i have a i5 750, gigabyte ga-h55-usb3, ripjaws 12800, super old hd

i have another question, on my hijackthis log..does everything look normal? i remember reading somewhere that the "(file missing)" is that hijackthis isnt compatible with 64 and shows up that way.

ill be honest im completely lost with the memtest, thought i used it before but i guess not. can i get a lil help? do i just put it on my usb drive and restart and it auto runs?

i feel so noob right now...i restarted 4 times trying to get this to work, burned the .iso onto a cd after unzipping it. checked it in the cd rom to make sure it read it and it did. so i restarted but nothing happened, i restarted it again and went to bios and put cdrom as first read or whatever its called with hard drive second. still didnt work, so i tried my other cd rom, which it still didnt read the cd. while the computer is on it reads it fine but only as "view folder"
