Seems to have fixed the issues thank you

hmm the fix recommended worked for a coupe hours, looks like the windows 8 issues are fixed but flash still hangs up after 10 min and requires a restart

did a system diagnostic's,  said pci express fail, what does this mean and how do I fix it?

Hi tstirling,

I am sending you a private message as well. Click on “Inbox” to respond to the message and provide the system’s Service Tag and contact details(including the name on the account) so I may access your system records and check for further course of action.

pci seems to have fixed itself, when I ran dell system check it came up health now, don't know why?

Still major problem with flash on desk top freezes desktop after 4 or 5 min of use, very frustrating for a 1600 machine
