I've just recently converted from xp to 7 and i feel like all my knowledge on computers has gone.
I've only had my new laptop for 3 days and ever since i started using it i have had crashes, i do not get any error codes or BSOD's the laptop just becomes unresponsive so i have to turn the machine off by the power button.
After a certain period of time (random, sometimes crashes after a couple of hours, others a few minutes) a program or the explorer in general acts like it is loading but really has crashed and there is no way of it closing and restarting, if i do manage to get a program to close then i can't re-open it, i click on the icon but nothing appears.
Also after a certain period of time when i try to right-click on an icon on the desktop/start panel etc. the system crashes and becomes unresponsive as well.
I can manage to get the system to restart but even then (after experiencing a crash) i have to turn it off by the power button.
I realise this is very long-winded and probably won't make much sense but ever since i've gone from xp to 7 i feel like a complete novice.
I have performed various malware/registry scans to no avail in fixing the problem.
I hope somebody can provide me with anyway to sort this problem without having to send my laptop back.
