Vista freezes after login [Normal & Safe mode]

[exasperated_man]

Hi, all.

My usually faithful laptop crashed today morning after giving me a blue screen of death, while I was playing a game.
Since then, my PC always freezes immediately after 30secs ~ 1minutes of logging into Vista.
I have tried to reboot the machine in Safe Mode (in Normal Safe Mode, with Networking, with Command Prompt) but it still freezes, albeit I am given a little more time before it goes down.
I have used 'Last Known Good Configuration' - No success here either.
I have attempted 'Repair Your Computer' option during booting. 'Startup Repair' didn't seem to find any problems.
Windows Memory Diagnostic Tool also found no problem.
I tried System Restore, and after being a little buggy (freezing once/twice before being successful) it worked but did not solve the problem.
I haven't backed my system in last six months, and I would REALLY prefer not to lose my stuffs on the laptop... My PC is a Samsung R519 with Vista Home Premium (RAM: 3GB, HDD: 320GB, no Graphic/Sound upgrade) I've used SuperAntiSpyware and Avira AntiVir Personal 9, although I've added MSE only last week.

I am literally at my wits end, and would be very grateful for any assistance.

Thanks in advance,
e_man

Hi, Joeten. Thanks for your response!

I've removed Avira and tried to do a clean boot, but now the system now freezes on the log-in username/password screen on normal mode. Fortunately, I can access safe-mode... does this prove anything?

Thanks!

Hi you can either try running a repair from your install or recovery disc or use system restore and retry removing avira but use revouninstaller to do it
