Computer doesn't POST

Q: Computer doesn't POST

#1
Hi,
I have an HP 8300 Elite Small Form Factor Desktop Computer, Intel Core i5-3470 3.2GHz Quad-Core, 8GB RAM, 500GB SATA, Windows 10 Pro 64-Bit.

The problem is the computer will not Post and the fans will spin very fast for few seconds then stop. Followed by power light flashing and a series of four short beeps (repeats 5 times). After the beeping stops the power light flashes continuously.

I bought and replaced Power Supply, Ram and battery for the CMOS with no avail. I also tried a different HD, removed, clean and install a processor but the problem still persists. Also, the motherboard components show no physical damage.

What else can I try to solve this issue?

Preferred Solution: Computer doesn't POST

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I turned my computer off last night and tried turning it on this morning but nothing. The computer doesn't even perform POST. I unplug all of the components that are not vital to the system. Tried a different video card but still nothing, most likely the motherboard but any other suggestions?

My computer won't POST. I plug my RAM, CPU, PSU and let my Mobo lie on static paper, connect my keyboard and monitor, and my computer will still not post. All my parts are brand new.

Specs

Mobo : Asus P5GL-MX
CPU: P4 S775, 2MB cache, 800FSB
RAM: 2x 512MB PC3200, 400mhz
PSU: standard 20pin + 4pin 420W PSU

I'm leaning towards a problem with the motherboard, but i have a hard time believing that it won't work, straight out of the box. I ruled out the possibility that the connection are properly made because its kinda hard to miss where the power supply goes.


Can there be a problem with the thermal greese? wouldn't that cause the computer to shut down?

anyway, ill appreciate all the help

I have seen this thread somewhere on this site before, but the problem was never solved

Can you give more details about what happens when you power up?

Do you have any lights on your motherboard?
When you hit the power button, do fans spin?
Any beeps?
Absolutely NOTHING?

Hi all,

Hoping somebody may be able to help a newbie out with an issue I'm having.

I have a computer that won't enter into it's post. When powered up, the fans all run fine and it will even display video, but it just freezes at the "Biostar" display screen.

Motherboard = Biostar M7SUA

This started happening after a software upgrade that required a reboot, but I have a suspicion that this is more of a hardware problem rather than a result of an upgrade to software since it doesn't even go into post. However, the computer worked fine up until this reboot was done.

Wondering if this is a possible bios issue and how to proceed. Any thoughts or suggestions?

Thanks.

Hi Pablo76 and welcome to the TS Forum :wave:


I would disconnect the IDE devices first and see if the PC boots, I have seen this happen when the HD is going or gone faulty.

Occasionally when I boot up my computer, it doesn't get past the MOBO screen and POST, after I press the reset button once, it usually works. I don't think I have had to press it twice. But like I said, this doesn't happen often. USUALLY it happens when I turn on my computer after it is shutdown for an hour or two (or overnight).

I don't know what is causing it to hold up but it's quite aggravating.

If anyone has anything to say/suggest let me know.

A:Computer doesn't POST occasionally

I'm not sure I understand. Could you clarify?

POST is the Power On Self Test. It happens first. The system will normally beep once if POST is successful.

Then the BIOS or UEFI loads and runs it's routine. (which do you normally have?)

Then the operating system is started ("Starting Windows").

Where in this process does it freeze?

Hi all. So I have a custom computer i built a couple of years ago. Yesterday I purchased a new case fan. Before installing the new fan, I blew out the entire computer. I got everything good and proceeded to try and power up. The tower seams to come and run fine but i'm not getting anything on either of my monitors ( i've tried both on their own and still nothing ). This unit was running totally fine until I took it apart for cleaning and the fan. So far I have tried resetting the cmos, reseating the ram, and GPU, trying to boot with 1 ram. But nothing has worked, I cant get anything on my monitor. I have checked all of my connections and it should be fine. I hope we can narrow this down to the GPU so i can just replace it. If anyone could help me in any way it would be greatly appreciated. Thanks!

Hi guys

My brothers computer which came with 8GB of ram, which posted fine when we first bought it.

When you turn on the power the lights come up the fans start working but it doesn't go to the beep and it just hangs. The monitor doesn't show anything at this moment. If you try just turning it off and on for like 20-30 times it boots up properly and works fine.

I tried to use the search but there are no complete threads with solutions.

Hello all,

Preface:
I am building a computer for my girlfriend's mom and today the parts arrived. I built my own gaming computer earlier this year and had no problem. Before that I hadn't built a computer for over 5 years.

ASUS M2N-SLI Deluxe AM2 NVIDIA nForce 570 SLI MCP ATX AMD Motherboard - Retail

*I am using an older IDE CD-Drive from an old computer I have (but I know this has nothing to do with my issue).

My problem:
The computer powers up when I start it, but it doesn't post. Everything seems to be working fine - the CPU fan, case fan, hard drive, optical drive, graphics card, PSU, are all powered on, and there isn't any automatic restarting or shut downs. The monitor just displays a blank black screen, and the power light is blinking like it is sleeping (just as it does when my computer isn't on). Also, there are no beeps (I believe this means it's not passing the power-on self test?).

This morning I turned my computer upside down on my carpet to fix a slow leak at the drain plug of my water cooled computer. I need to use some epoxy on the slight crack at the drain, so after fixing it, I left for work with the computer still upside down. (I still had water in the system and couldn't replace the plug until the epoxy hardened) When I got home from work, the computer was on it's side, somehow it fell over. Since it is water cooled, it's rather heavy so I suspect the whole computer took quite a shock. (Did we have an earthquake sometime yesterday?!?)
When I set it back up and booted it up, the fans work, the pumps for the water work. the mobo's lights work, the hard drives spin up, but that's is as far as it gets. No beeps, No POST screen, nothing on the monitor at all.
I cleared the CMOS, removed the battery, removed all of the RAM but 1 stick, removed the hard drives that didn't have the OS on it, removed 1 of the video cards, removed the CD and DVD drives and just went with a bare bones set up. Same thing, no beeps, POST............ect. The only thing I noticed when I set the computer back on my desk was that the speaker switch and the power LED switch were pulled out of the motherboard and the pins were slightly bent. I straightened them and plugged everything back in and still the computer runs but doesn't boot the OS. Can anyone think of anything else I should try?

Problem: Upon system startup, power comes on, but nothing else--no beep to indicated the system has entered POST. After several tries, it will finally beep and the harware will come to life.

Once working it will usually keep working as you'd normally expect as power cycle to work. It's mainly after sever hours of being off and now always, over night that the error occurs--no power to the hardware, until several tries.

But they have been contained, before they could do any damage, so I hoped, except I just got a bounced email yesterday, that shows I have been spoofed and my address book copied and is being sent to. So a Trojan got in.

Hey everyone, I'm in dire need of some help with my PC. The computer turns on fine, and boots up (can hear the windows start up tune) but I can't see anything on the monitor. Here's the details:

I was playing a computer game on friday, and during that it crashed. I have no idea if this is when things started or not, but I restarted and it was fine.

On sunday I had another crash, only the screen flickered once or twice and there were green pixel lines going from top to bottom of the monitor , about 2 inches apart in a perfect pattern. When I restarted, there were no graphics on the monitor. The light was flashing indicating it was on power saving mode.

I took the computer apart, unplugged everything, and put it all back together, and for whatever reason it worked fine for about 6 hours.

The next day I turned the computer on, and it loaded fine, but shortly after there was the return of the green pixel lines, with the added addition of the top left corner of the screen being filled with green pixelated triangles in a perfect pattern. These were flickering furiosly.

I tried restarting my computer, and again I got no graphics posted to the monitor. However the computer booted up fine, and I heard the start up tune, and 5 minutes later I shut it down by pressing the "Power Off" button on my keyboard.

I tried another monitor and again, got nothing. I then tried taking the computer apart and putting it back together again, only this time it didn'... Read more

A:Graphics card doesn't post any graphics to my monitor, computer boots up fine

Its usually just the graphics cards, they do fail especially if they overheat - then video card fan not speeding up might have been the problem - most are dynamic and should actually speed up under load. Depending on the manufacturer of your 8800GTX you might be able to get it replaced under warranty if they have a 3 year or greater warranty.

I gave my old Athlon XP 2800 to my mom. I built it myself and it has an Epox 8RDA+ motherboard.

A week ago she said when she turned it on it beeped and nothing came on the screen. I had my dad look at it and he said the CPU fan wasn't running. This was the fourth or fifth time we had turned it on to troubleshoot it (I live 500 miltes away) so I'm not sure if it stopped running when he was messing with things, or if it hadn't been running the whole time.

Anyway, they sent it to me and I've tried troubleshooting it to no avail. When I first turned it on it got to the bootup screen before freezing. At this point I noticed the CPU speed was listed as 1100 Mhz. Now when I turn it on it doesn't show anything on the screen (what would cause this, a heat issue?)

First I was getting a C1 error, so I tried switching out and trying to each memory stick individually. No luck. Eventually I ended up with a wide array of post codes, including:

C1: Detect memory
26: Reserved
29: Program CPU internal MTRR, Initialize the APIC, Program early chipset, Measure CPU speed, Invoke video bios

Sometimes it would boot up to 29 and then go back down to 26

It seems 95% certain to me that either the CPU or motherboard (or PSU?) has gone bad. Is this correct? If so, how can I find out which one it is so I don't buy the wrong thing? Thanks a lot.

The disk is a 20G and it reads (under dir command) 16G free.
These facts make me think formatting is not necessary.

Hi there,

This has been my first PC build, which was a pretty daunting task for myself. I will list my specs below that SysInfo retrieved.

The title basically explains it, every now and again, the PC will not show the ASUS Bios logo. It will not get past this black screen stage until I hold in the power button to turn the PC off and then boot it back up again. My keyboard and mouse have LED's in them, so I know if the LED's light up, it will boot normally. If they don't light up, I know I'm going to have an issue.

Being a ASUS P8Z77V-Pro motherboard, red LED's light up one at a time to (assumingly) test each component for errors. Whenever the computer has decided to do it's weird not-reaching-POST thing, the DRAM_LED is lit solid red, and will not move on to any component no matter how long you wait. I don't know if I have faulty RAM, a faulty motherboard (which I'm quite frankly dreading, and I mean honestly dreading, I've got too much pressure on myself at the moment), or some issue.

I'm not an expert, but I'm fairly clued up on technical jargon. I do not believe I've made any mistakes whilst building this PC, but I hope someone can help me here.

I have an Dell Optiplex GX260 that isn't going past POST. It ends with "press F1 to continue, F2 to enter SETUP" (or something similar) Pressing F1 does not good, it just repeats the phrase. Entering SETUP shows that the HD and CD is unknown. The date is correct so the battery is probably okay. The HD is probably wiped, but I can't be sure at this point. (The other HDs on the Optiplex computers we received were all wiped.) With the CD listed as unknown, even if I got the computer to move forward, I would be unable to install XP. I tried changing the HD but it made no difference. I also checked to see that all cables were connected. The RAM was seated correctly and worked in another computer.

Welcome to BC CaroleAnne

Sorry to hear about your problem, you have come to the right place - I'm sure we can shed some light on your problem!

Just some things to consider:
- How long has this problem occured?
- Any strange messages prior to the comptuer failing the POST?
- Did anything strange happen prior to the problem?
- What operating system are you using?
- Does the computer make any beeping noises?

Am I right in thinking that your computer has a set of four lights on the back panel labeled A, B, C & D?

Hope this helps so far!!

-checking the sticks one by one on different slots

The psu, cpu, gpu and the monitor are fine because I checked if they worked on my old mobo so it seems like its the motherboard or ram. Any ideas on what else I can do before taking it to the repair shop (trying to avoid that due to covid).

Hello. I'm not entirely sure where to go for help at this point, so I thought I'd try looking for help here. I've got a couple problems with my PC that I need help troubleshooting since I'm not experience enough to do it myself. Also, I couldn't think of how to title this thread to convey the best message in the least amount of words, so I apologize if it's misleading.

It started off with me installing a new PSU, the EVGA SuperNOVA 750 G2. I put it all in, and wired it all up, but I made a stupid mistake by using the same wire that my previous PSU used to plug in my SATA devices. It made since at the time since the old cable fit better, but upon further inspection, the two SATA power cables used different pins when plugging into the PSU. Long story short, my SSD was burned and no longer works. I have reason to believe that my HDD no longer works as well, and now I'm starting to worry that my Motherboard or CPU is also fried. I started my computer up and it went to POST just fine, although it did actually recognize my disk drive, which was still wired to the same wire that burned my SSD. I then turned it off and let it sit overnight since I assumed I would just need to buy a new SSD and possibly a new HDD. However the next morning, after I had unplugged and removed all my SATA devices (being the two storage devices and a disk drive), I turned it on and the motherboard did not POST, and did not even send any signals to my monitor.

You need to get yourself what is called a multimeter to test your psu. Make sure it is digital. You can buy one at Radio Shack or Sears/K-Mart for little money.

I bought my Craftsman a few years ago at K-mart for $22.00 and it works great.

There are numerous You Tube Videos that will show you how to test your power supply as well as online articles. The rails you want to test are the +3.3V, +5V, and the +12V.

Hi,

I have a PC with a Gigabyte GA-8SGXL MOBO and a P4 2,4Ghz. It worked fine until it crashed last night. I was just copying some files and suddenly the PC stopped responding to anything. It seemed like a regular XP freeze. I turned it off and can't get it running since. When I hit the power switch, the PC powers up (fans, HDD, DVD-drive all running) but nothing appears on the screen. My monitor just displays "NO SIGNAL". It doesn't even give any audio signals.

I tried everything I could think of, but nothing helps.

Recently I got a new monitor for my motherboard (Asus M5A78L-M) due to the old one dying, the reason was that there was no posting to t he screen. It was an OEM, Pegasus motherboard that usually dies out sometime anyway, so replacing it was probably sitll a good idea.
After replacing it, putting in all the cables and things of that matter, it still won't post. I've tried switching the RAM into different slots, but still nothing will show up on the screen.
Everything else works fine, the fans work and the lights are lid up where they should be. THe DVD-Drive does open, but closes a couple of seconds afterwards. Also, other things like a mouse and keyboard light up for a second when it turns on.

I really need to diagnose the problem before I spend more money on this stuff.

A:New motherboard still doesn't post to the monitor?

I would start by checking the monitor and the cable. Switch both out with known working monitor/cable to see if you get a response.

For clarification, did you only switch out the motherboard or did you buy a monitor as well? We need to know exactly what you're trying to do to provide the best answer. I think you're saying you replaced the mother board and nothing is showing up on the monitor, correct?

Hi All!

I have a very strange problem with an imedia 1529 running XP Home.

It was brought to me because it wasn't getting beyond fans starting, disks coming up. There was no 'power on' beep.

I figured it was the motherboard and probably the graphics card fried, and sure enough when I fitted new ones and cleared out the dust which caused the problem it fired up properly. I ran it for a couple of days and called the owner to collect it.

After a couple of days' use it seized up again, and after some cleaning of contacts and reseating cpu, memory etc, and putting arctic silver on the cpu it restarted.

I have now got it working three times, each time for several hours, and each time when it was returned to the owner it refused to start, with the same symptoms (no beep, etc). I have tried running the board outside the case, with no extension cards, to see if it was a shorting problem (it wasn't), removing the cpu, memory to see if I get beeps (I don't), and trying another PSU, resetting the bios and renewing the battery, all with the same results. At present it's still not booting at all.

Am I missing something Really Obvious?

Many thanks for any input on this.

PS I have very little hair left...!

Hi guys, having a rather odd and frustrating problem.

I purchased a new CPU cooler and had to remove the MB to fit it. Everything went fine but when I plugged it all back in the PC powered on, fans and drives started spining but nothing displayed on the monitor (no error beeps either). After a bit of screwing around I figured I damaged the MB while removing/fitting the cooler so I went down the road and bought a new MB. Went through the install process of fitting the new board, but once again same problem! Power but no display, monitor light just blinks.

I tried a different PSU, RAM and video card but nothing helped.

The only thing I haven't changed is the CPU (don't have a spare). Could the CPU be fried? I don't see any scorch marks or smell anything. When I insert the CPU without the heatsink I can feel it get hot and then cools when I power the PC down (only did for 10 seconds so I don't really fry the CPU). To me this "indicates" that the CPU is ok, or will the CPU continue to heat even if it's dead?

Any suggestions/ideas?

Oh, one odd thing I noticed immediately after fitting the cooler in the original MB was after I powered the PC on the DVD drive made a strange sound and the light blinked. I pushed the eject button but it only came out half way and then went back in. Never seen that before.
 

A:PC powers on but doesn't boot - no POST

Have your tried a new MB? maybe somehow if broke something in it. i don't really think your cpu is dead, i have had old processors that i bent pins and dropped and spun around but they still worked when i built older system for family * pins were bent back straight just so everyone know* i would think that something is wrong with your motherboard but thats just me i could be completely wrong. hope you find the problem though

Just built a computer for my little brother and I live streamed it for Charity. Unfortunately, it's not posting. The LED's come on and the fans spin but no signal from the monitor and no signal from any devices such as the keyboard and mouse.

When I plug the computer in it turns on, but the power buttons in the front of the computer do not work. Which means I can't turn off the computer by it's power buttons, I have to unplug the power. There is a green LED that shows in the front of the computer as well. So, I know the motherboard is sending signal to the case.

Things I have tried so far: Double checked the Q connectors (Case connectors) and removed one stick of ram to ensure it's not a ram problem.

I've got a T410s 2904G2U That isn't POSTing and displays nothing on screen and the CAPS LOCK key isn't responding. I replaced the motherboard with FRU P75Y5925 and the RAM is Samsung 2GB 2Rx8 PC3-8500S-07-10-F2. I'm suspecting it is incompatible RAM that isn't allowing BIOS to be stored and that it is failing silently. What are your thoughts?

I've had a problem over the last couple weeks. My PC doesn't start easily. I have to hit the power sometimes once and it starts or I have to power down (6 secs on the power button) and repeat this several times before it posts to bios and starts. The PC power will start, the fan runs, but it doesn't consistently start. IF IT DOES START UP IT IS STABLE AND RUNS OK.
I have a Gig P35DS3R and am running Vista with current updates. Bios is version 12 beat (Award I think - Gigabyte's version). Today no matter how many times I've booted the PC does not post. HasaAnyone seen this before and can help with diagnosis? I'm thinking its the mobo, versus the PS.

Hi,

I have an oldish athlon 64 on an Asus M2V motherboard and have just upgraded to 4GB (2x2GB) at 800mhz.

For some reason, the BIOS and W7 says that there is only 3.25Gb although windows does say "4GB (3.25GB usable)". The manual and "Tech Specs" on Asus' website says that it can support up to 8GB so I don't understand why it isn't recognising it. Any ideas?

Also, it is Win7 64bit Pro.

Another also, the pc sometimes doesn't POST when restarting and just sits there with all the fans spinning, but after a few tries it POSTs and goes into w7 with no trouble. I did memtest on the ram and it errored with both sticks in one way but not the other and so I currently have them in the way that they are working.

Thanks for your time
 

A:Windows 7 reporting 3.25GB when got 4GB and sometimes doesn't POST

There is nothing wrong with the read out you are getting on your RAM as the missing amount will be in use by graphics or running processes.

Your boot problem is probably an early sign of a failing hard drive or RAM. Check your RAM configuration in the motherboard manual, there is often a right and wrong way to install the sticks.

The best test for the RAM is to run the PC with one stick at a time for several hours using memory intensive games or play a video. If errors occur the stick needs to be replaced.

Follow this guide to test your hard drive.



Identify the make of your hard drive and then use one of the links below to get the manufacturers diagnostic for ISO CD. Burn the image file to a CD, boot the PC with the disc in the drive and run the diagnostics. You first need to set the CD drive to 1st in the boot order in the Bios setup.

If you do not have an image burner use this free software to make the CD.

Someone has handed me an IBM Thinkpad, Model T43 (Type 2686) that doesn't proceed past the initial BIOS/POST splash screen with the IBM logo. It just sits there. No beeps, not errors, not reaction to keys pressed (like the IBM Access key). I've even removed the DVD and HD, and removed the keyboard panel to clean the inside out (very very little dust to speak of; clean overall) and re-seated both sticks of RAM. Same problem persists, even without the drives in their bays.

I'm not sure what to try next but am leaning towards a problem with the motherboard. I'd like to exhaust my options before declaring a replacement board to be the solution (though it probably will be).

Thanks
 

A:IBM Thinkpad (T43) stuck at POST, doesn't proceed further

I don't see what else you can do if you can't get far enough to boot anything.

Except perhaps a 'recovery type' Bios flash if that laptop can do it, the sort where it finds the Bios file automatically if you press the correct key combination.

elllo folks
ive just finaished changing my cpu from a amd phenomII 965be to a fx6100. i was under the impression that my motherboard waas fully ready for the bulldozers. ive checked the gigabyte website and its in the supported cpu section. or am i gonna have to flashe the bios? never done it b4 but iknow to use qflash but thats aboutit.

any help will be much apreciated. thanks in advance

system specs r in the details below

A:installed amd fx-6100now bios doesn't post

What is your BIOS version? The FX6100 CPU is supported, but only with Bios version FGf (or newer). If your version is only FB, then you currently do not have support for that processor.

You can upgrade the BIOS version (if necessary) by downloading it from here: GIGABYTE - Motherboard - Socket AM3+ - GA-880GA-UD3H (rev. 3.1)



   Warning
Flashing your BIOS is a risky business that can potentially leave you with an unbootable system. Always follow any given instructions explicitly. Remember that, should you choose to do it, you do so at your own risk.

Hello,
I have an Emachines T6414 with a new videocard and sound card, neither of which require a seperate power connector than their slot on the mobo. THey were both in the machine for a few months when I decided to update my BIOS. I was updating my bios, and everything appeared to have worked. At the end it said: "success...press f1 to reboot" so I did. Then the problem started.

When I rebooted the PC the computer did not post, it only had all the fans (CPU, Main and Videocard) going full blast and the hard drive made a little noise, but nothing booted. I reseated the CPU, same thing. I called Emachines tech support and decided that the bios process actually didn't work. So, I bought a replacement bios from an online vendor, Biosman. I gave them the BIOS that the tech support had emailed me. I switched out the bios for the new one, and the same process happened still-no post, full fans and the hard drive warming up. At that point I bought a new PC and got the Geek Squad to transfer the data over.

So now I have come here for a last gasp attempt to revive the POS. I just read that the power supply could be the culprit. How should I determine what part has become faulty?

Thanks in advance. :dead:

Note: edited, because I just need help with the POST/sleep issue, not the BSOD.

I'm having a series of problems I'm just losing my head over.

1) First off, I never had a single stability problem while the PC is running, in fact it's quite new and I've been using it without any issues. However, as soon as I put it to sleep there will be a chance that it will simply not wake up next time, regardless of sleep duration, forcing me to turn it off and on again.

2) When this happens, it will take some random attempt at rebooting it because sometimes the POST will just not happen, and I've tried every combination of button press/USB unplugging/power cut. I don't know why power cycling/manually erasing the residual charge doesn't do the trick, but I might be doing it wrong.

After that, once it boots I get everything working as usual as if nothing has ever happened; the PSU voltages seem to be fine, the motherboard/GPU/CPU seem to work correctly, I can play games, watch videos, develop apps, fill 16 gb of RAM no problem...

What is this? A software issue? A hardware issue? The BIOS? A faulty Windows installation? I'm simply losing my head!

My specs are as following:

- Windows 7 Professional SP1 (I have some updates due)
- Corsair CX500M 500 Watt PSU
- Gigabyte 990FXA-UD3

I wanted to get more RAM for my older PC (CPU Q8400 on Asus P5P43TD PRO). The motherboards' specs say it works with 1600Mhz RAM so I bought 8GB of Kingston HyperX Blu (Kit 2x4GB), code KHX1600C9D3B1K2/8GX.

I already have the latest version of BIOS but it doesn't POST for the life of me (fans are working, black screen, no beeps). I tried inserting only one stick (tried all 4 slots). I tried both sticks in slots 1 and 3, both sticks in slots 2 and 4, still no luck.

When I put back my old RAM (2x2048 Kingston Value RAM) it works just fine. Everything in BIOS is set to AUTO. I tried increasing the RAM voltage to 1.65v as specified on the new sticks without success.

I'm sure the memory is fine but I just can't get it to work. Any suggestions are greatly appreciated!
 

A:Asus P5P43TD PRO doesn't POST with new HyperX 1600 RAM

You may need a BIOS update. CPU and Memory compatibility updates are common BIOS updates. Before you give up on the RAM modules, try updating your BIOS.

ASUS Support For P5P43TD PRO

Caution though, follow the instruction carefully. The updating can not be interrupted once started. It only takes a few minutes to complete, but any interruption can brick the motherboard if it is not equipped with a backup BIOS.

I just recently bought a motherboard I thought was completely dead (same symptoms as your board, no post). I never suspected the motherboard wouldn't recognize my i7 CPU. The tech guy had me use an i3 to flash the BIOS. Low and behold the BIOS update worked.
