Hi. I have a Gateway T-6836, updated to Windows 7 Ultimate 64-bit a few months ago from Windows Vista Home Premium 64-bit. I've had it for about 2 years, After 1 year a virus killed it, and I reformatted it. Now, a few months ago, unknowingly, my flash drive contracted a virus from my school's pc and infected my laptop. I think I most likely deleted the malware or whatever it was, but it left some side effects, such as some services being unable to start. It was also at the same time I installed a windows update, so I'm not sure if it's both a malware problem and/or a Microsoft problem. It deleted all my system restore points after I restarted the computer. My laptop is completely isolated from the world. No internet, fails to detect anything in the usb slots, and the CD-rom is broken When I'm not connected to a network, there's a yellow asterisk sign, when I'm connected there's a big red X button and I get 'limited connectivity.' When I try to troubleshoot the problem, it gives me "The Diagnostics Policy Service is not running" Tried to repair it and failed. I tried starting it manually in Services but that gives me "Windows could not start the Diagnostic Policy Service service on Local Computer. Error 5: Access is denied." Tried perfmon /repair failed. It gave me an error: "Error: An error occured whiled attempting to generate the report. The service did not respond to the start or control request in a timely fashion."
