Greetings CH!

last night i was using my PC and noticed something a bit different. My Machine currently Dual Boots windows XP/7 both 64bit. I walked away from my computer while using XP and it went to sleep after returning an hour later I went to wake it up. The Computer came to life but the screen was blank. It didn't display anything. So i rebooted it and it Posted. The second time same thing! The third time that night it woke up from sleep but took a bit longer than usual. I never seemed to have this issue with either OS. I didnt try the 7 ULTIMATE partition yet. I read someplace that this can indicate a hard disk drive FAILURE about to happen, is that so? or has my Windows Xp 64bit partition somehow become corrupt? Any way i can test my drive? Its a 1TB WESTERN Digital 7200RPM that has 4 partitions. Below are my system specs:

AMD Fx 8120 3.1Ghz 8 Core CPU (on XP partition 6 cores are shut off)
Asus M5A97 motherboard
8Gb DDR3 RAM (2x 4GB)
1 TB Western Digital hard drive 7200RPM (i think its a black model not 100 percent SURE yet)
MSI Hawk R6870 1GB GDDR5 Graphics card
750 Watt Coolmaster (i think) PSU

Let me know thanks. DLoad and run the Data LifeGuard tool from WD...run the long test.
