Bad problems

[SpikeyThorn]

Hey, as of late, i've just started having random problems with my computer...

It's taking no time at all to start up, but when it does, it's slow as ever, i've bought and extra 4gb of ram recently, which was broke when i bought it, so im waiting for a replacement, so i only have 4gb at the moment...

Im seeing this is the processes



If i try to load minecraft, it crashes...
