So my computer started acting weird... In google chrome it would randomly left click, redirect etc, scroll continually. Also suddenly our motherboard ethernet port turned orange and we would be disconected from the internet... i could resolve that by using cmd and using ipconfig /renew , /refresh and /flushdns. I scanned using avg anti-virus and found nothing. Then once when i started up there was two options one f1 to continue and f2 the enter setup i pressed f1 and soon after started getting bsod with a repair loop either i choose continue which would bsod or repair which wouldn't work and restart. During the bsod it would flash really quick and go away so i turned off auto restart on crash (so i could see the error) and then changed the bios to load up cd-rom and ran avira rescue system...it found the virus and said it was renamed as something and removed it. So i restarted and changed the bios back to load up the harddrive and not the dvd, and still got the bsod and start-up repair loop. Now im stuck at what to do because i cant access the bios when the hard drive is connection to change it to load up dvd (so i can run the rescue cd again)I will press f2 or del like it tells me to load bios but then it just goes to the two options of continue or repair. Also if i physically disconnect the hardrive it will go into the bios but i wont have the option to change the boot priorities. Plz help!
EDIT: I have tried following the unbootable system tutorial, but when i start up pressing f8 doesn't bring up Adv Boot Options. I'll start it, wait for my keyboards lock keys to flash and then press f8 but it doesnt work.. and pressing f2 doesnt bring me to the bios. The only way i can seem to get to the bios now is if i disconnect my harddrive.. but there is no boot priorities without the harddrive. Also when the harddrive is connected no bios info pops up anymore, before a 555 logo would pop up saying pres f2 or del for bios etc but now it doesn't appear at all... Also when i get to the startup or continue options the arrow keys dont let me move up or down and enter doesnt select although pressing num lock will move it up or down, but the num lock light will not switch on or off with this also at random times the scroll lock light will turn on and off...

Sorry for the delay in responding.

The first thing to do is check the hard drive with the manufacturer's diagnostic tools.

Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.
Bootable Hard Drive Diagnostics

If that's okay then run chkdsk and System File Checker from the recovery console to make sure there are no file system problems.

How to run chkdsk or System File Checker (SFC) from the Recovery Console

• Boot your Vista or Windows 7 installation DVD
• When you see "Press any key to boot from CD or DVD", press Enter
• At the "Install Windows" screen, click on Repair your computer at lower left
• At the System Recovery Options screen, make note of the drive letter assigned to your boot drive (normally C:) and click Next
• At the Chose a Recovery Tool window, click on Command Prompt. You will be sitting at X:\Sources directory
• Run chkdsk or SFC
• If you did not note the drive letter of your boot disk, you can enter bcdedit and look at the osdevice line to see what it is.
• For chkdsk, type chkdsk c: /r and press Enter (use the letter from above if not C:).
• For sfc, type sfc /scannow /offbootdir=c:\ /offwindir=c:\windows and press Enter (use the letter from above)

Let either run to completion undisturbed.

Vista or Windows 7: If you don't have a install DVD, you can download a legal copy here:
Official Windows 7 SP1 ISO from Digital River via Dell
Download Official Windows Vista RTM with SP1 Setup Files (32-bit and 64-bit)

Make sure you get the same version you have installed: 32 or 64 bit; Home Premium, Pro or Ultimate.

Also, even though you ran scans with your AV, you may want to go to the Virus, Spyware, Malware Removal forum, read the first post and follow instructions.

Come back here once you get a clean bill of health if you still have problems.

THANKS!!! I'll tell you how it goes

Ran chkdsk and at the very end it says "488282111 kb total disk space. 435929812 kb in 331502 files. 194784 kb in 44246 indexes. o kb in bad sectors. 507771 kb in use by the system. 65536 kb occupied by the log files. 51649744 kb available on disk. 4096 bytes in each allocation unit. 122070527 total allocation units on disk. 12912436 allocation units available on disk. Failed to transfer logged messages to the event log with status 50." Then i ran sfc and got Windows resource protection did not find any integrity violations.

That's all good so no file system problems or corrupted operating system files.

Do you have anything else connected to your computer? If so, disconnect (printer, external hard drive, any USB devices, any Bluetooth devices, any Firewire devices).

Are you using wireless keyboard and mouse? If so, switch to wired (USB or PS2), see if that makes a difference.

Power down the computer.
Remove the power cord.
Open the case and remove the CMOS battery (silver, about the size of a quarter).
Press and hold the power switch to drain all capacitors (10 seconds or so).
Put the CMOS battery back.
Connect the power cord and power up.

You should get an error message about corrupted BIOS, press F1 to enter Setup, F2 to continue.
Press F1 to go to Setup.
Load defaults (Fn key or selection from one of the windows).
Set everything the way you want it, then save and exit.

See how that works.

Well I can access the bios now and set everything how i want, but when i load from the harddrive i see an asus logo then i get the bsod. It restarts and brings me to Start up up repair or continue. Startup repair fails and continue still bsod and restarts... (I have not done the cmos battery technique you posted above because i assumed that was only to access the bios which i can do..) Also i switched to a usb keyboard and can now switch between statup and continue as well as access the bios using f2 or advanced boot options..

We need to see what the BSOD screen is displaying. See here: My link

Select 9) Disable automatic restart after failure.

Reboot and record the BSOD info to post here please.

[iNiles]

Okay all of a sudden it went back to normal! No bsod it stated up regularly, the only thing i did was run SeaTools for Dos Long Scan... Restarted to see if it bsod's, it didn't.. what should i do to prevent this from happening again? (It might have been caused by a virus or avaria rescue scan deleting said virus instead of renaming it..)

[Ztruker]

While it's working, make sure you backup anything important. An image backup to an external hard drive would be excellent.

If the BSOD comes back, think about reinstalling Windows 7 (after you have stuff backed up). Sometimes that's the only way to resolve intermittent problems.
