Turned my computer on yesterday and it would loop through boot sequences. I think it might be hardware related but don't know for sure. I got the Windows XP cd to boot from and did a chkdsk /r but that did not help. I then ran a repair installation which worked but put me back to downloading an endless supply of Microsoft updates including Service Pack 2. This took forever with high speed cable and I still haven't finished. I might get a new power supply to see if that makes a difference. Computer runs and boots slower now. I have an Asus A7N8x Version 2 motherboard with a Western Digital 120 Gig hard drive running Windows XP Home with what used to be service pack two. My power supply is an Antec 500W which is about 4 years old. About two months ago I wanted to update my video card but not buy a new motherboard with a Pci express slot (my current MB has 8X Pro Agp), so I bought a XFX GeForce 7600GT 560MHz 256MB video card with the additional power connection on the card (4-pin molex connector). Since then I have wondered it I'm not getting enough juice to everything. Oh, one more thing.....not sure if this relates but better give all symptoms. Starting a couple of months ago, if I would leave my computer on and unattended for about an hour, I would come back and move the mouse to get the screen to come back on but it would not come on. It was like it did not want to wake up. This only happen 2-3 times and it resolved itself if I did a hard shutdown (hold down on front power button). Any suggestions????
Oh, the last thing I did before I shut off computer before this happened was allow Itunes to update. It then asked to reboot and I clicked no and shut it down for the night. In the morning, I got this loop which suggests safe mode and last known good configuration but doesn't allow you to use those choices.
