Was sure it was PS, but it is not... STUMPED! Please come help.

Thought it was cheap PS, but trying a new PS (Antec) didn't post my computer either.

Computer crashed, BSOD, then no bootup, constant beeping from MB, but power comes to all drives and all fans working, but not post.

Any ideas why?

TB 800
kt7 raid
45gig ibm
radeon aiw
pioneer dvd
plextor cd-rw
caseedge case and cheap PS.

Possibly ...
1. MB and/or CPU fried.
2. Heatsink was not attached to CPU properly (hence constant beeping from MB warning of CPU temp??)
3. Bad MB and/or CPU from manuf.

I've had this rig working for a month now without any prob. Initially when I first got it, the system crashed and toasted MB & CPU after just 4 days! Since I had them replaced,(including old PS with warranty) it's been working fine for about a month. Now this.

Any Ideas please.

Constant beeping is usually RAM. Make sure you have seated all your RAM correctly, or make sure that you haven't fried them.

Try your ram in a different slot.
