Guild wars 2 has stopped working (game)
Only TERA online (game) and Planetside 2 (game) work
And photoshop keeps malfunctioning with a weird background malfunction behind the canvas
Im probably downgrading to windows 7 as Windows 8 was the worst decicion ive ever made
does any know how or why this is happening
and I di a full scan of my pc with McAphee and I have no bugs
anyone know how or why this is all happening and a solution, and will downgrading to windows 7 work???

Have you rebooted the system to see if a clean start clears it?

Did you install anything just before the problem started? Knowing may help someone resolve the issue for you.

I haven't rebooted the system, because that will clear everything and I have about 266gb, and I did not download anything prior to the event

'reboot' just means to turn it off and back on - not to refresh or restore it...

could you clarify whether you bought a new machine with win 8 pre-installed, or upgraded from win 7? It makes a difference in whether you can roll back to Win 7...

yes i turned it off and back on and nothing changed, it came with windows 8 pre installed,no more apps havebegun to stop working

it sounds like a computer problem, as opposed to a Win 8 problem. If it were me, i would be taking advantage of my warranty. But i'm not a techie, so maybe someone else here has a different take. Meanwhile, a call to wherever you purchased it (if within 30 days, or store-warranty period) or the computer manufacturer wouldn't hurt anything.

but since Win8 is pre-loaded, it is doubtful you can even roll back to Win 7. The computer itself likely can't support it for lots of reasons you can google but i can't explain ;-)

good luck!
