Hello,

I have a computer that I recently had to install a new power supply. I changed the power supply and worked fine for about a day. Now if I let it sit for awhile, it will start to start up and get to about as far as the Windows XP screen then shut off. Then if I try to restart it, I get and beep sound..alternating beep between two tones. It barely makes it out of the bios before shutting down then. I had pulled everything (ram, processor, graphics card) out before I changed the powersupply. It worked for about a day and then the next day nothing. Any thoughts?

Yes, I replaced with same wattage power supply. I will try removing the RAM, but I think it was the ram it would not start up at all and would be solld beeping noise not an alternating one. The other fact is it worked for 8 hours the day before.

Dear Sir,

Did you replaced the power supply of same power??? I mean the watt?

This is may be a ram problem,

Just remove and insert it again
