Old Asus M3a32-MVP Mobo + AMD Phenom 9850 Not Posting, No Beep, Etc.

Hi there, I apologize if this question has been asked, I looked around a bit and couldn't find much regarding my hardware, at least not the answers I had hoped.

I recently built a new gaming PC: AMD Ryzen 1.5 3.2GHz (Socket AM4), ASUS ROG B-350F Gaming MoBo, 16GB G.Skill DDR4 RAM, 500GB Samsung SSD, and using my "old" GeForce 960 GTX and OLD 650Watt Antec EarthWatt PSU. I needed a new system to keep up with the new games coming out, and the switch over went perfect.


I had HOPED to just buy a cheap 500-600Watt PSU.. I got a 500Watt for like $20 online. As well as a cheap PCI-E Graphics Card GeForce 9700 for $10. I hooked everything up into a cheap mid-ATX tower... unfortunately the old AMD Phenom 9850 CPU and ASUS M3A32-MVP Deluxe Motherboard are not giving me anything but a blank screen. I'm guessing I may have damaged something during the transfer to the new case?

I tried the "old/new" GeForce 9700 on my NEW system (AMD Ryzen 1.5 CPU, ASUS ROG B-350F Gaming MoBo) and it worked perfectly fine. So I knew I didn't get a bum Video Card as it was cheap off an auction site and was worth the price whether kept as a backup or not.

I figured, maybe it's this 500W PSU which should be plenty considering it's pretty bare-bone (no CD-ROM, small GPU, no extra gadgets/fans, etc), so I tried hooking my old system back up via my 650 Watt Antec PSU, still the same thing.. no beep, no picture. So I've narrowed down the problem to either the CPU or Motherboard.... because I know that with bad RAM the system would at least beep, post, show me something... but nothing, just a blank screen as I hear the CPU fan spin and watch the green light on the motherboard stay lit.

The Motherboard lights up on BOTH PSU's, the CPU fan spins (Zalman Heatsink) as well as any fans connected to the motherboard. There is nothing else I can think of besides that the CPU died out (perfect timing!), or something on the Motherboard is busted.

The old system was playing some of the newest games wonderfully, despite the old CPU and 8GB DDR2 RAM it was literally playing Destiny 2 the day before I built my new PC. I wanted more power, and considering the motherboard/cpu are 10+ years old I guess I am lucky it lasted this long to begin with... I was just hoping to keep it and give it to a family member who has a piece of garbage laptop that complains all the time.

Old System Specs:
AMD Phenom 9850
ASUS M3A32-MVP Deluxe
8GB G.Skill DDR2 RAM
GeForce 9700 GTS (also tried my 960 GTX... same problem)
500 Watt PSU

I'd be more upset if my new PC didn't work lol, but it's a shame this old system went dead on me.. I feel like it got mad at me? Maybe the 500Watt PSU shorted something? But as I said, the MoBo lights up (so it's ON correct?). But the CPU, which I did not mess with, nor the heatsink... I have no idea... I guess I can search online for a cheap older AMD Phenom... Socket AM2 I believe.

Maybe I just answered my own question. I apologize for the lengthy post, just wondering if anyone had any ideas... I will keep trying, I think I will at least try buying a cheap AM2 CPU that should fit this board fine... if that doesn't work, I guess it only narrows it down to the motherboard, which I can probably find cheap somewhere as both these pieces of hardware are literally 10+ years old... thanks and I will certainly document my progress, or lack of!

    No luck after trying a few tricks/suggestions I read throughout a few posts, tried taking out the RAM, air-blasting any possible dust, etc... still no beep, no post, no screen. Tried 2 different monitors, 2 different PSUs, just going to say the CPU died even though I looked at it, pins look fine, reapplied thermal-paste/heatsink, tried again.. board still lights up, heatsink still spins.. but nothing.

    Ordered another AMD Phenom 9850 BE CPU and ASUS M3A32-MVP Deluxe MB off eBay for cheap, both "refurbished", also ordered a 600 Watt PSU. Heck this system gave me a lot of fun over the past 8-10 years, but I guess it just got jealous when I got my new system and it stole it's home (my customized PowerMac G5 Case) I modded.

    This new system runs sooo much cooler it is scary, the heat the Phenom/M3A32 produced was insane, both systems are running on air, but the old system was like a nice little personal space heater for my feet under my desk, this new system is so cool (on air), and so quiet (SSD most likely vs old SeaGate 1TB SATA).

    God Bless Everyone, apologies for what is most likely a repetitive post, it was hard finding a post for the exact issue, but after seeing similar problems for similar boards/CPUs it seems like the board must've gone, or the CPU... which is a shame since I was going to give it as a gift to someone who is still on an Intel i3 Laptop. Anyways I will continue to document this pre-holiday fun. I loved my old system, it treated me well. RIP buddy :(

  2. Well I ordered an ASUS M3A78-CM motherboard, it was pretty cheap off eBay, used/refurbished, whatever. I figured let me give it a shot with my old Phenom 9850 BE CPU, popped it in, hooked everything up: 600Watt PSU, 8gb g.skill ddr2 ram, seagate 1tb sata hd... and the system booted up perfectly into Windows. I honestly stopped researching and paying attention after I had purchased and built my Phenom/M3A32-MVP but this motherboard the M3A78-CM actually has on-board HDMI, so no need for the little GeForce 7900 GTS or whatever it is.... so now my old system is back up and running great, I did not have to reload windows or any software, have had no glitches, I just need to find a cheap wireless/wifi card, whether PCI or USB, doesn't matter, and this will make a nice little holiday gift to replace the family's old i3 laptop downstairs hehe.

    I purchased 2 other cheap AM2 AMD CPUs, another Phenom 9850 BE and an X4 9750... and 1 other motherboard, an ASUS M4A785-M. I guess I will most likely put together another system for the holidays, probably borrow 1 stick of 2gb ram from the system listed above, just need to buy a cheap HD and possibly another wifi/wireless card/adapter.

    Welp, I answered my question, I really thought it was the CPU that went bad, but nope. The AMD Phenom has held up like a champion.. and hopefully continues to purr. I did see a little burn mark on the motherboard, right on the CPU socket/slot where the pins go, just on one side, so maybe something shorted out, just strange how it happened, when it happened, and why it happened at the time it did. Either way both my new system and my old system "rebuilt" are running great, and cool. Wow, people weren't lying about the heat the M3A32-MVP Deluxe's put out, I can't believe I put up with it for all these years, but I sort of miss it now considering it's turning into winter here in NJ and I miss my little "space heater" hehe.
