Windows 7 Starter netbook unreadable square text

Hi, hope you can help out once again.

I've been handed a friend's Samsung netbook (No cd/dvd drive) running Windows 7 Starter on which the system font has changed to unreadable square boxes instead of text.

Desktop icons are okay, though the start button is shifted to the left and I'm not sure but it looks like the start button logo is now to the right of the clock on the bottom right!

It crashes to various blue screens of death at the slightest opportunity. I've tried to run the f8 recovery console which whilst successful in running, did not fix anything.

The BSOD's cycle so fast I cannot even tell what error is reported, never mind any detail.

Any thoughts please or suggestions to help my author friend out?

I'm getting there!

It seems to be tied in to a recent Critical Update, getting System Restore to finally, and reluctantly to work, I've got the normal text back but have had to go back around a fortnight.

Even if going back as far as necessary with System Restore gives you a working configuration, I would still do a full scan asap with Malwarebytes : Free anti-malware download.

Then reinstall all of your Important and Optional Windows Updates to completion. If it fails again, restore to the last point and install them singly to find the one causing the problem and post it back here in our Updates forum.

Compare the install you have now with the perfect install in Clean Reinstall - Factory OEM Windows 7 as if this is the original Acer factory preinstall then it is an inferior install larded with bloatware and duplicate utilties which interfere with better versions built into Win7. I would do the reinstall at the earlier convenience and until then Clean Up Factory Bloatware
