problems..lots of problems

Hi guys,

Iam new to this forum and i just registered to post the problem i face the last 8-9 months. My english and especially my pc knowledge is not at a decent level i suppose but i hope you could help me.

First of all, sometimes my screen goes in sleeping mode and doesnt recover whatever i do. I even put reset button on pc but doesnt work always. Most times i have to unplug and plug again the screen cable to my tower in order to work. I was experiencing this problem for many years(i think i bought the computer about 5 years ago) and i changed my power supply(is that how it is called the little box of power feed to my tower?), worked for 1 year i think but now im having this problem again.

Moreover, i try to play some games but all of them whenever i launch them screen either goes black and blinking and having a kernel error message or pc makes a weird sound and there is goes the blue screen of death as you may call it here. For example,i bought last year nba2k14 and about 9 months ago the cd couldnt be recognised by my pc so i had to download the crack. I know that you dont approve these things but i dont believe this is the cause of the problem. Every time i play the screen freezes,goes black and recoveres in 3-4 seconds while a kernel message appears every time. All the other games,even very old ones(like lord of the rings:conquest) cant be played. Screen goes black and then directs me to the desktop where i cant click the game icon in the taskbar as it seems not to be responding.I have done several formats in hte past and i thought that i might have not installed some drivers correctly and thats why i downloaded a software to help me with this,but it seems "crap"(driver navigator).

*By the way, i bought my graphic card about 2 years ago.

Anyway, i would aprreciate any help guys. It seems that i have to give it to a technisian and buy some ram extra as its very low for nowadays standards but i would like to give it a go here since i dont want to be without pc for 2-3 weeks:-D

By the way,i downloaded in the past whocrashed but didnt know how to examine the results.

Here i post the results of the software you recommend to check the specs of my pc.

 

ok i hope i made it right this time!

 

ok i ran the scan you advised me to.

do you want me to post the results/text here or fix the errors manually(i dont know iam capable though)?

*as for the manufacturer advice...how can i check what is mine?
