I think I have a VIRUS or something

My computer just stopped working at full capacity
**my cd drive doesn't read cd's
**any memory drive/flashdisk is atumatically asked to be formatted even though I have used it on my computer before
**Any antivirus/spyware has benn disabled Avg, Spybot, CCleaner, Hijackthis
**When I try to open the programs mention above, the computer immediatly closes them
**I can't reinstall the programs
**my wireless card has been disabled

Does anyone have a solutionCan you boot into safemode?If you can boot to Safe Mode, try to run HijackThis from there.nope doesn't let me reboot in safe mode I tried it by doing.... run..msconfig and at startup pressing f8
when I choose safe mode it starts booting up and then upruptly restarts stating an error messege

we appologize for the inconvinience but windows did not start succesfully a RECENT hardware or software CHANGE might have caused this

I tried selecting to boot up with last known good configuration and it just boots up like normal

***While in msconfig I saw system resote would that help in any way???
***would it be safe to take all my pics and info and burn it onto a cd and just restore settings or have a tech erase the harddrive and reinstall everything again??You can try System Restore. You don't have to worry about your pictures, and data. System Restore won't touch them.dont have that option anymore i am in a ENDLESS loop of restartsit gets up to the windows logo and a blue SCREEN flashes really quickly then it restarts.
If you have your windows XP cd or your manufacturers recovery CD boot from that CD, choose to Install windows, press F8, then choose Repair windows. That will replace all of your system files without damaging your data. You should then be able to boot back into windows and continue cleaning your system.
