Computer restarts after system standby

[Purpletin]

I never turn off my pc but have it on standby mode when not using it. It used to go on standby and when I start to be on it again, it would directly go to the desktop, as to where I last left it at.

But now, my system restarts after it left standby mode, is this normal for XP?

I have tried over and over and looked through my power config properties, etc. but nothing I dont see any solution. I looked through to see if anything under the properties have changed, but everything has remained the same.

I seriously appreciate the help.

Thanks in advance!
