Change of CPU caused PC not to boot… now old CPU doesn’t work either!

by atomiczulu . Updated 18 years, 4 months ago

Ok, here’s my exact situation and I think that I have tried everything but maybe someone out there knows that little bit more that I need to get me through this pain….

Comp Specs:
Gigabyte GA-7VAX1394 Motherboard
1024 MB DDR333 Kingston RAM
2 x IDE HDD’s
1 x LG DVD Burner
350W ATX Power Supply
Athlon XP-M 2600+ CPU (new one) and Athlon Xp 2200+ CPU (old one)
Phoenix dual Bios.

I recently bought a new CPU (the Athlon XP-M 2600+ 266 FSB) and put it in place of my old Athlon XP 2200+. According to the motherboard specs it should work without any problems. In fact it is supposed to be one of the best processors for my M/B because it has a low operating voltage and can be easily overclocked.

Anyway, once installed, the computer would not even enter bios. No beeps at all were heard. The fans would go on and the HDD light would go on but nothing would happen. I did use Arctic Silver Thermal Compound and I made sure that the CPU and heatsink were nice and flat – correctly seated. I tried resetting the motherboard to default values and setting all of the switches to ‘auto’. I removed the battery for ten minutes and still no go. I have tried a different power supply.

The weirdest thing is that when I put the old CPU (the athlon xp 2200+) I get exactly the same result – no startup – no beeps! :sigh:

Could the athlon xp-m 2600+ have been fried and then fried my motherboard? Can thermal compound cause this? Note: Both CPU’s were clean when the compound was applied….

I am now stuffed because nothing seems to work! Please help….
Remember that this was a perfectly working computer when I attempted to upgrade the CPU… What could have changed?

Thanks in advance to anyone who can shed some light on this disaster…
