DV6-2120sp powers on, but no boot nor blink codes

Q: DV6-2120sp powers on, but no boot nor blink codes

Good morning to all! My computer was running fine, either with Windows 7 64-bit or with the upgrade to Windows 10 64-bit. My battery is dead, so i use the laptop without it. Just AC cord in. Last night, as i was setting up a Wi-Fi router at home, i left it on for about 3-4 hours.When i finished, i powered it down normally. This morning, i took it out and set it on the dinnign table, and when i powered it up, the leds from the sound, wi-fi and mouse pad stay lit, the fan starts up, the leds from the caps-lock and num-lock blink once, but no bios or OS boot. I powered it down, removed AC cord and reset holding power button for 1 minute+ 3 times, then power cord in and powered it up and the same thing happened, but this time i got 2 blinks from the caps and num lock, then 5 second pause, and another 2 blinks: BIOS corrupted, right? Since i have customed my laptop with an HyperX Fury SSD drive 240Gb from Kingston, i don't have the partitions from HP Recovery or HP Tools, so i tryed to get the BIOS file from HP Support and created a BIOS recovery flashdrive. The BIOS file is not the latest BIOS update tool from HP, it's Winflash, so doesn't allow creating a recovery flash drive directly, so i extracted the contents and put it in a 4Gb flashdrive, formatted in FAT32, Renamed HP_TOOLS, and tryed the whole reset process, then hitting Win Logo + B keys in and pressing Power button for 1-2 seconds to recover BIOS. Worked once out of 7 tries! Started the BIOS Recovery screen. Machine booted up fine... until 50 seconds passed on desktop and it crashed down (total power off!!!). Tryed to boot it up again, and now just fan, wi-fi, sound and trackpad leds stay lit, and caps and num lock leds blink ONCE, with no repetition... Tryed all the above again, and nothing happens, zip, zilch!!! Any light on this matter? Or should i stripp it down for the parts and smash the rest of the thing in to the wall? Thanks!

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'm trying to find out if there are blink codes for the 7275 tablet. I found a small blurb about the power button lights, but it doesn't say anything about white blinking lights. want to know if the white blinking indicates anything. (example: 2 white blinks versus 5 white blinks when you press power button. Below is the only thing I could find.

LED status
What it means

Solid White
The battery is charging.

Solid Amber
The battery is at low level with the tablet on or in a connected standby state - the screen is off but the tablet is still turned on.

The battery is not charging or the battery is fully charged.

Flashing Amber
The battery is at a critical level and does not have enough charge to power on. If the power button is pressed during this state, the LED will turn on for 3 seconds and then turn off. Continue charging the tablet.

A:7275 Blink Codes

Just about any of these blink codes OTHER than a battery-related one means a bad mainboard.

I'm not sure whether the blink code is a single blink repeating 3 times or 3 blinks. This is exactly what I see and hear after pressing the power on button: The F12 blinks , the fan runs and the CAPS LOCK BLINKS, the F12 blinks , the fan runs and the CAPS LOCK BLINKS, the F12 blinks , the fan runs and the CAPS LOCK BLINKS. Then everything shutsdown. This pertains to an 'HP15 touchscreen' w/ win 10 64bit.

Purchased notebook 11/16. Within the first week, the keyboard stopped working and the caps lock key emitted a blink code of 5 long blinks followed by 3 short blinks. I uninstalled the keyboard driver and allowed the system to re-install it.  That appeared to fix it--for a while. The next time that happened, I went through the Device Manager, a line at a time, checking for updated drivers. Almost a dozen devices were updated. That solved the problem--for a while. The notebook is about 6 months old now. I have been using it extensively, mostly video editing.  Two days ago, the problem arose again.  I have observed that I can be in the middle of using the notebook and the keyboard will suddenly shut down and the caps lock key will emit the blink code(s). The blink codes never appear on boot-up. I have run the extensive diagnostics and no problem was found.  This is the main reason that I need the definition of the blink code(s). Thank you. wise_old_owl

Thanks, Huffer, for your answer. That should have been obvious, but I just assumed that by now, the software was at a point where, if something went wrong in the middle of machine operation, the operating system, or the BIOS, would shut down the keyboard and display the blink code.

Looking for some help, think on right track but want to confirm and get things fixed.

Have a Tecra R840-S8450 that is having issues powering up. When you try to start it, the plug orange light flashes a code. That code is 01001010 which I derived from shortlong short short long short long short blinks of the orange power light.

So this is great progress, assuming I translated that right to 52h, which equals "EVER5V voltage is under or equal to 4.5V when the computer is
booting up". However it does not tell me what is wrong in such a way that I can try to do something to fix it.

Would appreciate some help, thanks,

Today while I was browsing the internet, my laptop suddenly shut off. I tried turning it back on. The lights on the computer blink once and the laptop stops. I have tried the discharging the whole system, but I get the same effects. I noticed that every light blinks white, except for the disk light, which blinks orange. What does this mean? I am sorry if this question has been asked before but I could not find a duplicate.

Hey all! Hope there's some help around... My t5500 randomly died. Would turn on for a few seconds, without booting then turn itself off. Swapped MB out, now get 234 blinking diagnostic lights (halted before transfer to BIOS control, and the fans slowly get louder.). This is with three different motherboards, two different cpus, two GPUs, two power supplies. If the BIOS isn't being transferred to, could it be corrupted? Is there a way to flash a new BIOS externally myself? This was such a great tower, and I'd rather keep it running than replace. 6x2gig RAM. First gen MB with fans on both bridges. Nvidia gtx 950 or fx1800 available. Single CPU e5530 quadcore. Terabyte Seagate 7200rpm. Any questions or input is welcome. I cannot work without my station being operational. Thanks all

I had previously hooked this up to my big screen via the hdmi.  The next morning I went to turn it on and got nothing.  Holding the power button down with power plugged in, not plugged in any combination for 1 - 120 seconds produces the same exact result.  The little light on the " i " lights up for exactly 4 seconds and then nothing.  I have tried a different power cord and get the exact same result.  I have tried using the emergency reset with a needle on the back of the device...same result. Any help would be great.

My daughter's laptop has died.  When you push the power button the power light on the side comes on and stays on and the hard drive light blinks momentarily then not at all.  There is a blink code on the Caps Lock key that appears to blink twice - one blink followed by a second about 1 to 2 seconds later, then a longer wait and the code repeats.  There is no LED on any other key.  I've tried the hard reset by pulling the battery and pushing the power key for a long time.  No change. I've looked up the blink code which says it's a corrupted BIOS and used the Windows key/B key combination before pushing the power button and nothing happens except the blink code continues. This is all that I can find to try with this laptop and the daughter needs it for her online college courses.  She bought it from Amazon and it is a refurbished unit.  Any suggestions? Thanks.

I have Compaq Evo 310 running XP 2. A few weeks ago it started hanging up more frequently than normal, with the only solution disconnecting the power.
Yesterday after restarting, I got the DOS script saying that I was having a problem and should consider starting up in safe mode, or starting normally and going to a previous restore point. When I tried to start normally, I went bact to the DOS page.

On about the third effort to restart, all I got was a screen with Cmpaq's name and "press F10 for setup, press F12 for network...." Pressing the function keys took me nowhere. Only way to proceed was to disconnect the power. Further efforts to restart continued to give me the same screen, and occasionally just Compaqs name without the note about function keys.

I put the restore CD that Compaq provides in the D drive, and the introductory screen came up advising me that if I wanted to continue, it would reformat the hard drive and reinstall the hardware. Since that was not my choice yet, I started to move the cursor towards the cancel button when it locked up. Only alternative was to disconnect the power. On one more start, I got the introductry screen without the cursor, but on subsequent efforts, even the introductory screen would not come up.
Now all I get is the screen with Compaqs name, which I assume is part of the boot proceedure. I do not get the note about the function keys. Fans run, lights on the drives flash,, but no action

A:Powers up but will not boot


I'm sorry if I was clear enough in my previous post, but an early symptom was that the machine started in DOS. It has now progressed to a stage well beyond that. When I power up the computer, the fans start, and the HD lights blink, as if something is looking at them. However part of the time I get a black screen, and part of the time I get a black screen with a large orange word saying COMPAQ. I cannot go anywhere from there, or I don't know how to go anywhere from there.

At an earlier stage , the screen with the large orange COMPAQ also had the option of going to setup by pressing F8 or F10, or going to a network boot? by pressing F12. Now this option does not appear. When it did appear earlier in this problem period, pressing the function keys did not produce anything. The machine does nothing except display this one word.The only thing I can do is disconnect the power and try again.

I have put two different disks in the D drive to boot up. As my earlier post said, twice the introductory screen for the Restore disk by Compaq came up briefly, but would not run. It has not come up in the last dozen boots. After your post, I also tried the Windows CD but it was not run or found by the computer. All I get on the monitor is the word Compaq about half of the time. Then the machine produces nothing else, and I have no options except to turn off the power.

I believe that the display of the word Compact, and then the options to go to setu... Read more

Hello All,

My desktop has ceased to "boot up". When I turn it on, it will restart itself quickly twice then beep once. It will remain powered up, but not boot into Vista (or the rescue disc). It sends no signal to the monitor, which insists it is it in "power save mode". I have tried attaching it to a different monitor, but the same problem persists, so I reckon it's the PC at fault.

The PC is a Dell Inspirton 530 desktop, with:

Intel Core 2 Quad Processor Q6600
NVIDIA GeForce 8660 GT graphics card

I'm not sure what do to fix it. I have data on that PC which I need to retrieve! Could something have "burnt out" inside or become loose?

A:PC powers on and won't boot

hmm.. theres no easy answer to that question, the first thing you should do is to make sure your monitor is properly plugged in, I wonder if it could be a hard drive issue because your computer dosent boot... check out your hard drive and make sure everything is connected properly, all the cables are where they should be cause when I was installing my new PSU, the system wouldnt boot, my solution was that I needed a spare cable from my other power supply to connect to the hard drive cause the two that came with the PSU were put into the CD/DVD drive and another important place that I cant remember cause I was frustrated at the time. If that isnt the solution, then, ill try to think of another cause

I recently discovered that my PC, which runs Windows XP, is no longer booting properly.

When I switch it on the fans of the power supply, motherboard and rear of the case all run but no vision is sent to the monitor and no lights are present on the motherboard or at the rear ethernet port. The usual single beep from the motherboard is no longer present and the internal hard drives don't sound like they're doing anything. The power and reset buttons on the front of the case are now no longer able to turn the PC off.

I've checked the internal connections for any loose ones but haven't had any success. I also tried removing the memory chips from the motherboard one at a time and then both at once as a way to check if the motherboard or memory is at fault. The PC had the same response with each of the memory chips running on their own and there was no error beep made by the motherboard when the computer was booted without any memory attached.

From what I can tell I might be in need of a new motherboard. But any advice would be appreciated!

A:PC powers on but won't boot

if you remove the RAM and try and boot you should hear a series of beeps to say there is no RAM installed. If you do not then that would indicate the motherboard is knackered.

Also beaware that just because lights come on it doesn't mean the power supply is ok. Try another one if you can.

Hey guys,

I am at a loss here. I got a PC that will power up but no boot into BIOS. The monitor will not come on either. All fans run the CPU warms up, (as far as I can tell by touching the heat sink) The hard drive is spinning too, but does nothing else. I switched the RAM already, to see if that is the problem. To no result. I know I had something like that happen before but I cant remember what I did to fix it.
Any hints or any tricks are welcome. Thanks

All the fans, graphics card fan and processor fan spin, the fans spin at the same speed, that about it, i cant hear the harddrive doing anything, my pc doesnt recognise my monitor, keyboard the LEDs dont light up when I turn it on same with the mouse.

There are no beeps as well when my Pc is booting up.

My system spec

AMD Athlon 64Bit 3200+

Only started doing this after i removed the processor, and now when i put the processor back in place the following above happens

Thank you in advance

A:Help please: Computer powers up, but will not boot

Was there a reason for removing the processor to begin with?

Pull the processor again and look VERY CLOSELY at all the little pins. Make sure none of them are bent over. If any of the pins are bent you will need either very small needle nose plires or a sturdy set of tweezers to straighten them. Once you are sure there are no bent pins make sure the processor is fully seated in the socket before you slide the lock over. Also make sure the top of the processor has been cleaned of any old thermal paste.

Once the processor is properly seated and locked down you are going to need a good thermal paste (Arctic Silver maybe?). Put a small bead in the center of the processor then mount the heatsink and clamp that down then mount the fan and make sure the fan is plugged in. If the fan doesn't turn on when you start up turn the PC off and recheck the plug.

Post back with your results.

I have a new computer that is running Windows Vista (quad core processor, 3GB ram, nvidia 8500 GT) and I encountered a serious problem today.

This morning when I turned on my monitor (I had left the computer running overnight - not in hibernation, just with the monitor off), there was an HP update window flashing with three recommended updates. The two that I can remember were an update to the system security and a motherboard BIOS update to improve system stability. I started the updates, minimized the updater and opened internet explorer. A few minutes later, the computer slowed significantly and the mouse and keyboard no longer responded, but normal use resumed in about 60 sec. When I was done, I closed internet explorer and waited for the updater to finish. While loading the BIOS update, it prompted me to close something called COM something or other with the option to cancel, retry or ignore. I tried retry a few times, but it continued to pop the same message so I clicked ignore and it notified me that a restart would be required when the update was finished. Once all was finished, I opened the start menu and clicked what looked like the power button. I expected it to offer me the option to select restart or shutdown, but instead the monitor immediately went dark and the computer seemed to be shutting down. After a few minutes, I grew concerned because the blue light on the front of the computer was still on and I could hear the fan, but the monitor was dar... Read more

A:My computer powers up but does not boot

You need to find out what sort of BIOS you have that should help with the beep codes.

Knowing the problems I had inserting memory I would have a really good look to see if they are inserted correctly.

I initially though mine were ok but they were not, it's easy to think they are in properly when they are not.

Try reseating the graphics card too. You could also try without the card to see if it boots (obviously nothing on screen).

Sounds very much like ram problem. I'd put money on it (a small sum anyway - lol).

I bought a new lot of compnents to make a build recently, put it together and managed to get it to power on. Initially I hooked up my PC to my monitor via HDMI and i got no display. So I linked it up through VGA. Still no display. I got no beeps or anything of the kind and have no idea what ive done wrong because the PC powers on with fans spinning, lights on and whatnot. The disc drive even opens and closes I took all the parts out of the case and set it up with just the MoBo, RAM, GPU and PSU attached and I have the exact same problem. I'm very inexperienced at this kind of thing but I'm fairly certain I didn't make a fatal error putting it together. Any help would be appreciated.

A:Powers up but doesn't boot

Its your PSU or maybe your volatge supply from power lines to your house. I also encountered a problem like this. I had so many theories but the problem was the PSU. I bought an AVR(Automatic Voltage Regulator) and the computer could boot but when there were any brownouts or power sags(voltage drop), the computer would turn off and start again..Especially when I played games because that was when the PSU would draw more power. This severly disturbed me because of the risk of my hard drive getting spoiled. Since it still couldn't work, I changed my PSU to another lower-powered PSU and its working perfectly now. I didn't have to change any of my hardware to be compatible with the PSU's lower power supply. It has never turn off without my command since then. Hope this helps =)

Hello! Thanks for providing this service, I hope you can help with my issue.

System specs are as follows

Windows XP Pro SP1a
ASUS A7V8X with a lot of the special features
Athlon XP 2400+
512 MB PC2700
Enermax 530W power supply
Dr. Thermal EXTREME SE + Arctic Silver III
3 IDE HDD (huge front case fan)
1 SCSI HDD (single drive front-mounted fan)
Radeon 9700 Pro 128 (requires A: drive sized power thingy)
SB Platinum Extigy
Adaptec SCSI controller
Extigy extension card (ditto)
Lots of ports and stuff
Way more system fans than anyone will ever need

Pre-existing conditions:

Several months ago, when I installed my CD burner and tried to turn my PC on, it killed my old 230W (stock) power supply, which took with it my MB, video card, one of my 3 256MB RAM chips, and CPU, prompting the upgrade to the above specs. Several weeks of video card instability followed until ASUS released a more mature AGP driver, and other minor hardware issues came and went. Still looking at a rather un-burdened WinXP install. Due to high CPU temperatures with the stock fan, I switched to the loud but dependable heatsink listed above. Before, all that hefty new gear meant that doing anything more than surfing the net bought my CPU past the 180 F (82.2 C) safety threshold of the MB and made the system restart or shut down. With the new cooler came average temps of 110 F (43.3 C) that only rose a few degrees even under great stress. And all was good.

Hey guys, got a problem, need some help.

My Dell PC has been shutting itself off during Windows Start Up.

This started happening a few weeks ago, windows and my start up applications would start loading, then all of a sudden it would shut down. Someone told me it could be one of a few things... fan problems and processor heating up and shutting down, RAM problems, powersupply, etc. So we played around. I had two RAM sticks in, one the original and one newer. When we took out the original the system worked normally. So i ran it for a couple weeks with one stick in with no problems. Just last night the same thing started happening. Windows would boot then while start ups were loading it would just shut down. I took out the remaining RAM and had it checked at a Comp USA. They said it tested 100% ok. So it doesnt seem like there is a problem with the memory.

Could this be the hardware (motherboard) related to memory? Or something completely different that we somehow mended the first time by removing the old memory stick??

Another piece to the puzzle is that both times this started happening were right after the computer had been moved from house to apartment... Could the problem be something was jiggled loose? It seems if that were the case it wouldnt boot up at all...

If anyone could help, I would greatly appreciate it. I am a graphic designer and have no system to work on now!

Hi, whenever I turn my computer on it powers off a few seconds or so after turning it on. I had a similiar problem not long ago (a few months maybe) where I took it to a PC repair store who replaced the motherboard and wiped the hard drive. I would do this again but the problem was it cost me almost ?90 so I'd like to know if I can fix this myself first. It's an Asus motherboard and has a pentium 4 processor which im pretty sure is 2.8ghz I can't say for sure what the hardware is because I can't get as far as the device manager. If I clear the BIOS it will get further to the XP loading screen before powering off though. Another thing that might be relevant was that before I took the computer to the shop for the first time I had an ATI graphics card but now I have an Asus one in there, I tried removing this and starting the computer with monitor plugged into the inbuilt monitor socket on the motherboard but the same problem happened. There's no bulging or leaking capacitors on the motherboard and because it's only a few months old max I don't think that's where the problem lies but I couldn't say for sure. Also the computer sometimes used to completely freeze where the sound cuts out and you can't move the mouse at all and the only way to come out of it was to power off and on again. One more thing is that I have the hard drive plugged in as a slave drive in another computer so I can access the files on it and it doesn't seem to have any problems.

the metal conductors that keep the mobo off the case... i screwed several in... some of them didnt have a hole for a screw so its just against the board... could this be causing that problem? grounding the mother board 2 the case? i just thought of it while i was sitting here in college and i have not gotten to test my thoughts.... possible or no?

A:computer powers down after boot up

YES they will cause shorting to the case. Only install standoffs where there are screw holes in the motherboard. A standard ATX motherboard has 5 or 6 mounting holes. This goes for miniATX boards too

I have a 18 month old Sony Vaio Laptop which, last night, decided to give up the ghost.

When I power it up it turns on, I hear the hard drive come on an the fan start up. I even get a flash or two from the processor light. But then nothing the screens stay black and other than the power light, the fan and the hard drive there are no signs of life.

Any ideas would be gratefully recieved.

This is what I have tried so far.

1) Initially I thought that it was the screen but when I attach it to an external monitor the problem persits. Also if it was just the monitor and the system was booting correctly the NUM and CAPS lock lights would come up eventually, which they don't.

2)As I can hear hear the disc drive checking for discs I Inserted Vista disc in an attempt to boot from CD. No luck!

3)Removed battery, left for 20 minutes or so. I then inserted the power cable and held down power button for 1 minute. Apparantly this should initiate a hard reset, although I'm unsure if this is true or not but I thought it was worth a shot at this point.

4)Now i'm desperate. I open the beast up and check it's not been bathed by one of the kids. I also checked for any obvious signs of damage or cables having worked their way free. All seems fine.

5) Booted whilst holding function key and F10

6) Suspended it in a nice hot cup of tea! unfortunatley no finite amounts of improbaility were produced. Nor did it boot up.

Hi, My Lenovo N200 laptop has recently started powering off during the boot process.

This happens consistently when the windows xp "loading screen" is displayed with the green loading bar.

I can get passed this stage in the boot if i turn on laptop and enter BIOS for a couple of minutes.

I have also noticed that a fan is audible as "whirring up" when the problem occurs but is not audible when xp boots normally.

I really dont know what the issue is, any assistance would be much appreciated. Thank you.

It might be dusty and overheating or this could be a thermal shutdown. The CPU may be getting to hot. You can used a compressed air or vacuum it. Then try running it on a cooling mat.

Hope this helps.. Good luck

My laptop is powering off directly after the loading screen for Vista. I can load safe mode (from where I am writing this), however, I cannot use the DVD drive to read any disks (such as the Vista disk for repairs...), as it also powers off when I put in a CD/DVD.

Furthermore, I cannot boot from a DVD either, as it powers of before the boot process, if I power up the computer with a disk in the DVD tray. This is before even encountering any OS installation (seemingly).

What can possibly be the issue?

Would it be safe to uninstall harddisk drivers for a reinstall, or could I risk losing data or ability to boot up if I do that?

Hi -

Given that you can boot into SAFEMODE, a start-up app may be responsible. Use MSCONFIG to troubleshoot.

My 4 yo gateway NV53 laptop just won't boot up although the power LED turns on and I can hear the fan and the hard drive running. I have tried connecting it to another monitor to exclude monitor problem. I have also tried draining the charge by removing the battery and then hold the power button for 60s. The screen is completely black and no error message come up. It is running on Windows 7 64bit Home media edition.

My issue is best described in this video - http://www.youtube.com/watch?v=Yt-bFeeS1Ls

I have an Acer Aspire 5552-7819, Windows 7. AMD Processor.

Bascially, I power on my laptop. The power light is on, I hear it begin to run, but it doesnt begin to boot up windows or anything, and I'm staring at a blank screen. So I tried doing a hard reset (draining the bios by removing the battery and holding power), connecting to an external display, and removing RAM. All did not work. What is very odd is my universal power adapter was set on 24v instead of 19v like it should be. My friend set it back to 19v and it powered on, so I thought that was the issue. I had a working laptop for about a day, and then the issue reoccurred. I've tried using my stock power adapter, as well as the universal one, and no adapter at all. Still have the same issue. It's weird that it randomly stopped working, began workign again, and now is not working again. What is the problem, and what is the solution?

All help very much appreciated!

A:Laptop powers on but doesn't boot up.

'fraid to say it doesn't look good at all. If it were just your hard drive that were the problem you'd at least have a message from your BIOS saying something along the lines of "Operating system not found". The lack of any BIOS activity at all indicates motherboard failure (assuming you're certain it's not a display issue, but it doesn't sound like it to me).

24V input on a laptop designed for 19V is a massive difference, though: never more than 0.5V above or below is the rule of thumb. I'm not sufficiently qualified/experienced to tell you that you cooked your motherboard, but experience tells me your mobo is cooked nonetheless. I've had two laptops die due to motherboard failure - the first simply stopped working from one second to the next, but the second died a slow and painful death where it simply became less and less reliable, until it finally stopped booting in the way you describe. The point being that readjusting the voltage on your power adapter may have been enough for one last power-on, allowing you and your laptop to say your final farewells.

Anyone else care to chime in and confirm/reject my suspicions?

So I've looked around for possible solutions to my problem.

My problem is I turn on my PC and I see a green led for my Motherboard power. The fans spin for just a second then stop, and no boot.

I've disconnected every component except the heatsink, cpu and fan.

I've tried resetting the CMOS by changing the jumper settings. No good.

I've tried switching the memory around. Nothing.

I've now taken the motherboard battery out and will re-insert it after this post is finished.

If that doesn't work I fear I'm running out of options.

I tried the PSU in another PC and it was fine. So I know it's not the PSU. I tried the OTHER PCs ORIGINAL PSU and that did gave the same problem.

I've read up on a couple of articles about shorting out the motherboard or power supply or something as a solution.

Is this true? It sounds more destructive than creative.

If anyone has any advice or suggestions I would really appreciate it.

This PC is extremely new. Literally half a year old. It has a BFG 850w PSU, an ASUS M8 Motherboard w/ an Athlon Dual Core Phenom 3.2GHz

It has built in SLI with two Nvidia GTX 260s

Two 1gb HDDs

it has about 5 fans including two graphics card fans.

it has 4gb of DDR2 ram.

So I have had this trouble for a month now. I moved from my apartment to the new home I purchased and made certain I was the one to pack the computer, which was basically the last thing to go before we left.

At any rate, this was a custom built PC that isn't even a year old. All parts purchased in 2015. When i power on the pc normally it doesnt boot into windows, but actually every now and again i can actually get it to boot. I have tried various trouble shooting for this circumstance. Swapped ram around, removed CMOS, reseated video card, etc. It can't be the ram as I've tried every single chip and I have 4 ram chips. I don't have any other video cards, PSU, or motherboard to try out to rule out the problem. Any suggestions? It completely puzzles me as to why it will randomly boot up sometimes but 9/10 times it just sits there with a black screen. Oh and by the way I get no beep codes from the motherboard anymore. No beeps at all.

The following are the components that are in the build:

Asus P8P67 LGA 1155 Intel CPU Support
Intel I5 2500k Sandy Bridge
G.Skill F3-12800CL8D-8GBXM Ram
Radeon HD 6870 xfx graphics card
Basia 550 W PSU
500 GB HDD

I'm pretty sure that they are all compatible, but the issue is when ever i hit the power button it starts up for 5 seconds then the power cuts out, but a few seconds later it powers back up. LED's on the mobo are on, HDD is spinning, all fans are going the CPU and Video Card included.

I swapped the graphics card with a buddy's of mine and it worked fine on his rig. The issue that i'm experiencing is that it doesnt Boot at all. The computer stays powered on but nothing ever goes onto the screen. Granted i'm a new to building PC's but i think it might be either the Ram, or the Mobo...

any suggestions?

A:New computer build, powers up but won't boot

So when you power up your PC, it starts and then turns off and then back on? So you swapped a GPU with your friend and the PC booted, or what?

Have you overclocked yet?
How many sticks of RAM do you have, 2 or 4? First try only with one stick. If the problem stills persists then swam for the other Stick.

What OS did you install?

I am using a HP Pavilion 734n, XP SP2, AMD Athlon. More if needed.
Anyways the problem is the other day I noticed my comp had rebooted itself. It was at the Windows login menu. So I clicked the owner and it started to load windows, then stopped. I saw the background, the icons, the taskbar, etc.... I figured it locked up, so I held the power button to turn it off then rebooted. Same scenario. Background icons etc.... So I tried once again this time I got the improper shutdown. So I tried safe mode, it got so far and stopped. Now it wont load past the same point in safe mode. It also wont load past pushing enter on the start Windows normally.

Also it now has a habit of just not powering at all. I looked in back and the led in was off. So I unplugged the power cord and plugged it back in the light came back on. I pushed power and it died again. I unplugged the cord again then plugged it back in and let it sit a bit, started up got to the menu to choose safe mode normal last restore etc... tried normal and it died while I waited. Now it may load the parts where it stops or it just dies.

Any ideas?
