Hi everyone, I'm running Windows 7 Ultimate 64bit on a Dell Dimension E520 that has an Nvidia GeForce 7300LE Graphics Card. Last night I installed an update from Nvidia and all seemed ok.Powered off went to bed and rebooted this morning.All still seemed ok and I opened WLM & Chrome, 10 secs later the system froze.So I held in the power button for 5 secs and the PC dutifully shut down. Tried to reboot,got past the windows splash screen but that was it, no login screen.Repeated this process 3 more times with same results.So I went into safe mode and all my system restore points were unusable.Tried to repair it rebooted and ran chkdsk,rebooted again,still the same.Tried the repair option again and it saw that windows had not started and listed disk corruption.So I ran chkdsk again and it came back fine but this time on the reboot the screen came up with masses of zeros. This continued on subsequent reboots so I got my disk out to reinstall.All was fine here until near the end of the install when it failed 5 times.Sooo out came a live linux distro which works fine ( I'm using it to post this)except the screen is low resolution and there are vertical purle and blue stripes outside of the linux gui.Have checked SMART on the HD and its Healthy and run CHKDSK and all is fine, no bad sectors.The only thing I can think of is that the Nvidia update shot my card. Does this seem most likely to you guys ? Ps. I don't have another card to swap with!! Look forward to your thoughts, TIA, Arfer.
