Power supply problem?

Yesterday my main rig began acting up. When I moved the mouse, the cursor on the screen would leave multi-colored pixels scattered randomly on the desktop. Sometimes the pc would hang and other times the video would go black for about 2 seconds.

This began happening after I tried to swap my Athlon 1.2 for a XP 2100+. I later found out that the 2100+ was a t-bred and wasn't supported by the A7M266 MB. The screen flickering and cursor issue occured after I swapped cpus back to the original Athlon 1.2.

Upon a reboot and after POST, a message on the screen advised me that there was a conflict and for me to check the hardware monitor. I did this and found my +3.3v was showing between +2.7v and +2.8v. It was also colored red; showing the problem.

I thought this wasn't a big deal and didn't investigate further because today I built a new rig using the 2100+ and a A7N8X Deluxe E. Everything was going well until about halfway through the Windows XP intall I noticed that the mouse cursor was beginning to leave the trailing pixels on the screen as well as text on the screen would have random jumbled characters. A few minutes later, the screen froze.

I rebooted and during post a message warned me to check the hardware monitor. Sure enough, same low voltage with the +3.3v.

This is a power supply issue, correct? If so, why would it leave the mouse cursor trailing pixels?

you definatley have a power supply problem, try a new 450 watt good name brand, such as fortron, see what happens then.

Okay. Thanks, allanon. Tomorrow I'll have to hit the Computer show and sale for the 3rd day in a row!

This could also be a problem with your video card, or the PSU could have damaged it. Typically, the trailing artifacts and wierd text like you are describing is caused by a video card with bad/damaged video RAM. Try the PSU first (cheaper...better to borrow one if you can) but it may not fix the problem.
