Serious system problems.

I formatted my system day before yesteday,due to some problems.
Now after reinstalling all the necessary softwares,i got down to browse the net on opera.

After some time it said opera has encountered a problem & needs to be closed.

Also microft word was giving the same problem.

The pc is restarting randomly. :shock:

Also from today onwards when i boot in XP,the moment i get to see the desktop it restarts.

Also my one samsung drive is not detected,i checked the cables,the device manager it says no problems.But the tray doesn't open.

Also when i restarted the pc day before yesterday when it was running fine i got a error System has recovered from a serious error even though no error occurred.

Guys help me i can't survive without my pc.

What should i do??

Where did u obtain the source of the installation Disk from ?? personally I feel if its a software problem then the installation source is to be blame

Re-Install the Windows from a proper Installation media if possible

U have been affected by some virus.
My friend had a similar problem recently.
The only solution as Choto Cheeta has suggested is to reinstall Windows.

^^The media he used for installing is infected by some malware which gets installed with windows......install windows from clean source.
