Hello Everyone,

I need a little bit of tech help again.

I have a Windows 7 64-bit PC that suddenly stopped booting - I receive only a black screen (no BSODs visible, from what I can tell). On instinct, I tried restarting my machine in Safe Mode, however it keeps on hanging on the file aswrvrt.sys (I believe that this is an Avast! file, from Googling), and will not continue.

I tried using other Safe Mode options, with Networking and Command Prompt however the machine still does not boot. I also tried booting with last known good configuration.

Next thing I did was pop in my Windows 7 disk to try recovery options. Startup Repair was no help, as it detected no problems. System Restore was also useless, as it kept on encountering Unspecified Errors on all restore points I selected. I tried doing a chkdsk /r C: in the command prompt, however it took only 3 seconds, which is unusual. It looks my operating system isn't on the C: drive, when I input the dir command.

Basically I cannot get into Windows 7 at all, with any options I've selected. Would anyone have any ideas on what I can try to get my machine running again?

What I have available on me:
1. Windows 7 64-bit desktop PC (broken, will not boot)
2. Windows 7 64-bit Laptop (using this to compose this post)
3. Flashdisk with Linux installation that is boot-ready.
4. Flashdisks with varying space capacitiies, and external hard disks
5. Windows 7 64-bit installation disk
6. A whole lot of hope that this can be fixed
