Help please!

Thanks again all, I did the restore and everything worked fine on the windows 7 starter, no problems at all. I forgot to mention in my original message that I had upgraded the memory from 1gb up to 2gb. Last night when I restored the netbook back to new I downgraded the memory back to 1gb and when everything was set as I said it was all great. I did all the updates that needed doing and then changed it again over to the 2gb and everything was still good no problems at all. It was after all this and all the updates were done that I did the anytime upgrade again from starter to home premium, When it was all on and working I played around for half an hour loading music and stuff back on and everything started to go wrong again, but how do I find out if its windows or the memory upgrade that is causing all of these problems. Should I have upgraded windows before the ram? I have read that 1gb is ok to run all the versions of windows 7. Again your advice will be muchly appreciated. Pattie

Take out the extra RAM and run it for awhile to see the difference. Then put the RAM back in a test it to make sure the RAM or one of the slots isn't bad.

Check the logs at the time the problem occurs, as well as other System Resources, following these tips for Troubleshooting Win7

Its just one slot. The computer has said hardware faults have been detected.

Then run the RAM Test with Memtest86+, and the HD Diagnostics using maker's extended CD scan.

You may need to return the RAM upgrade. Is it spec'd correctly? What are the exact specs for the RAM you bought?

I exchanged the 2gb for the 1gb and it seems to be working great now, all updates are installed which I couldnt do before. Seems it could have been a faulty upgrade. I was assured by the man in pc world that this was the one that I needed, he was a 100% certain! Well fingers crossed all is sorted now. Thank you for all of your help.....
