Long time I don't show here.Anyway,last yeat I changed my computer for a new one.I asked the man to move my former computer hard disks to the new one.It had 2 hds,one with Win XP and for programs and the other for storage.The new computer haves Win 7.
2 days ago,after a long time running,my computer probably (I didn't saw it) reseted and for my surprise,it was then running with Win XP!I looked at My Computer if the HD was there,but was missing.Also,internet and sound and video cards weren't working. After some time reseting it,it came back with Win 7.However,after 40 minutes,the screen froze and in the next reset,it was running with XP again! Yesterday,it was just fine.Running with 7 and nothing happened,but today,again the screen froze and after the reset,Win XP...
Is my HD gone?
I take what n0e says way too seriously

Is there a partition somewhere with winXP installed? Check in Disk Management for other partitions (And to see if you can see the hard drive when it boots winXP)

This could have any number of reasons, but it is most likely a hard disc failure.
Do you have 2 HDDs or two partitions on one HDD? In any case, you could open your PC and check the cables going to the HDD. Also find out whether your HDDs are connected with SATA (thin red) or IDE (wide grey) cables. Then buy a new HDD with the proper connection (SATA or IDE), take out all your old HDDs, plug in the new one and install Win7. HDDs are cheap nowadays and a fresh install every once in a while is also a good idea.
Be warned though, there is also the possibility that the motherboard is damaged, in that case buying a new HDD won't help. To figure this out you'd need to replace the current Win7 HDD with your XP HDD and test this configuration for a while.
Sounds like your windows 7 hard drive is going down the pooper. Run HDDtune and see if there are any errors on the disk.
