MSI K7N2 will not boot system.

Ok, here goes. This is a brand new system from Newegg.com. I have already RMA'd the board once. Both times with a brand new board, the system will load and allow me into BIOS. The first board simply reset itself after 12 seconds, and wouldn't come back on. The second time, after restarting the computer (with no changes), it shows a black screen only.
The fans move, but nothing comes on the screen. The system doesn't make any kind of usual startup sounds.
In the previous board, I tried plugging a Duron 850 (a chip I know works) into it and got the same result, so I am fairly sure the CPU is good.
System specs:
350 Watt PSU (I believe generic)
2X 512MB PC2700 Kingston value Ram
AMD AthlonXP 2100+
80 GIG HD
20 GIG HD
2X CD-ROM
Radeon 9500 Pro
I have tried booting the system with no ram and nothing but the video and HD plugged in, and got no beeps. I have tried every damn thing I can think of. Changed jumpers, unplugged and reseated everything, used onboard video, everything.
Can anyone help? I cannot get anything to appear on screen, a case of the system not booting.

I don't have the PC right in front of me (I'm at school now), but I do remember that it is a 350 watt PSU with a 3.3 rail that does 24 amps.
I have tried one stick of RAM.
The weird thing:
I tried unplugging the PC and the BIOS battery for about 10 minutes. Afterward, the computer started with my HD's and CD-ROM's attached. However, after loading bios and switching the FSB to 133 (with my Athlon 2100+), the system wouldn't reboot.
I again unplugged and waited. This time, I simply loaded BIOS and restarted the system. Same lockup-no boot thing. I repeated this twice.
I left the battery out all for around 6 hours overnight, and now the computer will not start again. I'm sooo frustrated...

Msi 6511 will not boot

I received an msi 6511 and it will not boot, I only get a light on the floppy but I can not tell if the other leds are on because they are not hooked up (I do not have the manual to this board)!! The specs are
1.2 GHz amd athelon
384 mb pc100 sdram
onboard sound
onboard video
450 watt psu
Any help would be much appreciated!

Hi
Your athlon could either have a 100 fsb or a 133, they came both ways. If it is one with a 133fsb then the memory (PC100) is not fast enough to let it boot. Set jumper J6 to pins 2-3 for a 100mhz fsb so that the cpu fsb will match the memory.
See attached link for jumper settings if you don't have the manual. This appears to have been an oem motherboard used by packard bell among others.

Please Help, K7n2 will not boot.

Hi,
I've had this K7N2 up and running for about a year now. It's an xp 1700 at 1833mhz. It has fun fine and stable with no overheating problems whatsoever. The problem is this morning I turned it on and it froze right after the cpu speed of 1833mhz was being reported. The led code on the back indicated it freezes during "bios sign on".
--I tried moving the speed jumper over to see if I could boot up at a lower fsb and clock speed. It froze in the exact same spot but with a slower reported clock speed.
--I then tried to clear the cmos by moving the jumper over for a few seconds with the power off and it did not clear the cmos, upon rebooting it acted as if it was still overclocked to 1833mhz.
-- I tried to clear the cmos by taking the battery out for 30 minutes with it unplugged but that didn't work either.
The question is, do you think my mobo is shot? or is it the processor? Any ideas, I'm very open to suggestions at this point. I noticed newegg has some newer reconditioned boards for cheap so I'm not to concerned at this point, just wondering if it can be salvaged.
Thanks,
Jay

What type of RAM are you using? Try one stick at a time and try relaxing the timings.

My msi Z77A will not boot after several months of use

So I've had this pc build for about 7-8 months. The motherboard is the msi Z77A-GD65 and randomly this morning I went to turn on the pc and I didn't get a beep or anything. The pc just shut down and restarted up again but did the same thing over and over again. Everything seems to turn on but I'm not getting the post beep anymore and the code on the mother board says 55 (Early memory initialization). Does this mean that one of my sticks of ram might be dead? How do I find out which one? Any other help or suggestions? Thanks

After providing specs as flobelix has requested will certainly help in the troubleshooting process. First thoughts are PSU has become faulty, RAM stick(s) gone bad, or a long term OC has taken it's toll.
Test each stick individually in the primary DIMM2 slot.
Specs are:
msi Z77A-GD65 motherboard
Intel i7 2600k
12gb Corsair Vengeance ram DDR3 (3x4)
AMD Radeon HD 7850 2gb
I'm not sure what the power supply is off the top of my head but I can check if needed. I've tried testing individual sticks and I've had no luck, still keep getting the 55 error. Also I haven't done any overclocking on my machine.

MSI P43 Neo3 will not boot

CPU: Intel C2Q 9300 @ 2.5Ghz
GPU: eVGA 8800GT KO SLI 650/950/1620
Mobo: MSI P43 Neo3
Ram: OCZ Platinum 4GB (2 x 2GB)
Sound: SB X-Fi Gamer
PSU: Antec TruePower Quattro TPQ-1000 1000W
OS: Windows Vista Home Premium 64 bit
I put this all together, and it simply will not boot. Hard drives fire up, all my fans spin, optical drives try to read but I get no post to the screen whatsoever.
Also, I would like to add that I had two GeForce 8800gt's since I was the proud (sarcasm) owner of an eVGA 750 Sli FTW. I also own an MSI Radeon 1550 graphics card. All three were tried, system would post with none of them.
Any help you guys might be able to give would be extremely helpful, thanks in advance.

Hello,
please do this:
1) Take the board out of the case and test it on a non-conducting surface in barebone configuration.
2) Barebone configuration means:
- CPU (reseat CPU & heatsink, check socket for bent or broken pins)
- video card
- one stick of RAM (test both modules seperately in all memory slots)
- Keyboard
- power connections (Board: 4-Pin +12V CPU and 24-Pin ATX, Video Card: 6/8 Pin +12V PCIe)
[Remove all hard drives, optical drives, add-on Cards (X-FI), case wiring, additional USB Devices, Card Readers etc. from board and/or PSU]
3) After Hardware changes clear CMOS with main A/C power cable removed from PSU.
Did all of that, even checked with my with coolermaster 600w PSU with 2 12 volt rails. No difference.

Windows 8 and Canvio Desk 3TB: System will not boot when external hdd is connected

http://h30434.www3.hp.com/t5/Desktop-Operating-Systems-e-g/HP-PAVILION-A6109N-amp-windows-8-System-w...
Hi,
just recently upgraded to Win Pro on my HP PAVILION A6109N. I also bought a toshiba canvio desk 3TB. What I notice is that if I reboot my pc with the extermnal HDD connected, my system will not boot.
I have check my BIOS boot settings and the order of the boot.
I have tried disabling USB Legacy Support in the BIOS
I have reformatted the external HDD
but still my desktop will not boot if the external HDD is connected....If I disconnect the external HDD...the system will boot up ....
I am at a loss....*** scratching my head ***

Update: The only solution for me was to format the drive as ext3 and plug it into one of my Asus RT-N66U USB ports, as most routers don’t yet recognize 3TB drives as NTFS. It’s not much help to people who don’t have a router with this capability, and it also slows transfer rates to ~12MB/s.
Given the short length of the cable, your only other options are to have the 3TB Canvio sitting right next to you so you can unplug from a front USB port before each boot, or place it towards the rear of your desk and crawl under the desk to disconnect it from your PC prior to each boot.
It's a pity because Toshiba produce great internal HDD's, but my experience when it comes to external drives is they're simply junk. I wish I had read the reviews before purchasing.

The following instructions about the "Code Purple" error FAILED. Error is still present.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
***PLAIN ENGLISH QUICK AND EASY FIX FOR ALL SYSTEMS****
***Windows 7 code purple or Windows Vista code purple***
With the code purple error on the screen, press shift+f10 (the shift key and the F10 key (at the top of the keyboard) at the same time) to open a little screen called a command prompt. (So, you get a little black screen with white text that says something about your Windows verison first and a little ways down you'll see "C:\>".   It's all ready for you to start typing.)
Type the following line, just as you see it here...
notepad C:\hp\bin\checkdmi\checkdmi.cmd
so it will look like this
C:\>notepad C:\hp\bin\checkdmi\checkdmi.cmd
Press Enter.
You will see the text for the file listed in a window using a simple text editor.
Go to the beginning of the text. Press enter to make a space. Type this...
goto cleanup
So, whatever comes after, the first line looks like this...
goto cleanup
Save the file and exit notepad and restart your PC. You are good to go.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
RESULT: Same error and problem.
So, NOW THE SCENARIO IS THIS...[ And A CHALLANGE TO ALL HP Software EXPERTS]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1. The PC will not boot the System Restore CD's
2. The Original OS install and [HP_RECOVERY] disk sector has been severely damaged by
all of the following:
   A. Massive Virus Infections as shown by Kaspersky Virus Scan and cleaned up.
   B. The user had originally updated the pc to Vista Business Express Upgrade
       (Supplied by HP with the original purchase and warranty).
        (Prior to the upgrade, Media Center was working correctly.)
   C. The original OS product key(XP Media Center Ed. 2005) has been changed by the Vista Business Express upgrade.
   D. The destructve recovery done by PC-Doctor has done user file damage(s).
   E. All software, and possibly hardware could be corrupted & damaged by viruses,
   incomplete recovery, and the unknown failures and conditions.
To sum up, the system is locked in an unknown state, waiting for expert help.
(I can allow and manage to let someone diagnose, repair remotely using another OS i.e.Linux Opensuse 12.1, or XP Home ed if needed.)

Macbook Pro will not boot beyond grey screen. System freezes.

My Macbook Pro will not boot-up or get beyond the grey screen (with spinning gear wheel.) I've tried all the recommended actions: resetting PRAM, disk repair, permissions repair, re-boot in safe mode etc but still the problem persists. When viewing the safe-boot in verbose mode, the system seems to hang at the stage when it's checking the Airport & Ethernet - the last line on the page reads: "AppleBCOM5701Ethernet: 0 0 setFixedSpeed - logic error, speed any?"
Any ideas how to fix this without doing an Archive & Install?
I'm assuming that if I do an "Archive & Install" then I will lose all my Applications (VLC, Handbrake, MS Office for Mac etc.) Will this actually be the case? Will I lose them.
Any help gratefully received. Many thanks.

Archive and Install just affects the System files, so any apps you have should still be available afterwards. The Installer on the disk that came with your Mac, when you bought it, will tell you this before you proceed. Of course, you can always back out of the Installer if you feel chicken.
Notwithstanding it is still necessary to backup everything. You need to check that Time Machine is set to also backup your Applications folder. It might be set not to do this.
It may not be necessary to worry about this if you have the original installer disc(s). I think any stuff downloaded from iTunes etc can be re-downloaded. However, it's probably quicker to get Time Machine to backup your apps if you can afford the HDD space. It's bound to be quicker than re-downloading the stuff plus any updates. And of course there's those Apps that you have but forgotten about. What about them?

The system will not boot

Hello, I am trying to install windovws after the restart can not install Yosemite because can`t please format the hard disk.Please help because just yesterday bought macbooc

FYI...the top partition is too full. You need free space. You will need to remove the bottom partition then make the top partition larger. Make sure you have 10% or more free space. If you use Parallels or VMware you don't have to partition your drive. If you use the vm software you can run Windows wihtout having to reboot into bootcamp each time you want to use it.
See this link for help after you resize your top partition.
https://www.apple.com/support/bootcamp/
I forgot to ask...
If the system will not boot, how are you seeing Disk Utility. Are you booted from the Recovery Drive? If yes, then you will need to erase the internal drive and reinstall Yosemite on the internal. When you erase, make it one partition. You can add a second partition later that's smaller.
Note: you posted in the OS X 7 Lion instead of the Yosemite forum. In the future, asking on the correct forum gets the best answers.

New system will not boot up.

I am in the process of building a new system and it will not boot to the post. The power gets to the cpu fan and case fan for about 5 seconds then shguts off. I have to clear cmos to get the same response. Please help, I have pulled everything from the case and tried to boot with just the cpu and memory. Same result.

Would be nice if you guys had different psu's to try.
I recently had the "reboot loop during startup" problem with an Abit AI7 and the Antec TruePower 480. However, the problem didn't start to occur until several months after it was new. After replacing the PS with a 430 amp Enermax the problem went away.

Hi NcBunky,
Are you using Win 7 64 bit? Did you update the Texas Instruments (TI) USB 3.0 XHCI Host Controller?
I have an H8 1380t PC. Updated the TI USB 3.0 driver and had the same problem.
When booting the PC with the USB 3.0 external drive connected to the PC the PC would not boot. When booting the PC with only the mouse, keyboard, and a USB 2.0 external drive attached the PC would boot. Once booted you could attach the USB 3.0 drive and it worked fine.
Solution was to roll back (reinstall) the TI USB 3.0 XHCI Host Controller to the original factory installed driver.
System now boots with the external USB 3.0 drive attached.

System will not boot or POST

I have a Pavilion A8 Vision that will not boot or complete POST and does not communicate in any way. Fans are on, sounds from drives seems like beginning of POST. I have removed and replaced RAM with other piece - no change. When RAM is out of motherboard system will report 5 long beeps and repeat the beeps for 4 to 5 times. Need help and/or advice on replacement of components.

System will not boot up

MB: KT6 Delta-LSR
CPU: XP2500 Barton
GFX: Asus V9520 Magic/T 128mb
RAM: 1028 pc3200 ddr400 (2x512) Geil Branded
HDD: Maxtor 40GB 2mb Buffer
Put it all together formatted the HDD, installed windows, network was working perfectly. (on ASUS via600 board)
Next day turn it on and nothing, zilch not even a flashing cursor top left of screen, dont even boot to DOS. screen is completely blank.
Tested CPU, GFX, RAM and PSU in another base unit and they work fine, yet put them all together and nothing.
1st I thought it was the mainboard so I sent the ASUS board back and ordered the KT6 Delta nice looking board. But still exactly the same problem.
Lights on case are lit all fans are turning ect yet still the system will not boot up i dont even get a flashing cursor top right of my screen.
There is no light with this mainboard for some reason.
All components work when fitted to another mainboard in a different case.
NB: one thing I have noticed is that there are two power sockets on this board,
1. The usual 20 pin socket (which I am connected to)
2. A 4 pin socket near to the CPU (whilst my PSU has a plug that will fit this sockect also, I am unsure as to connect instead of/as well as or leave unplugged.

Like I have stated before, it is the compatibility issue related towards your chip fsb and your memory fsb. I know that not everyone has money to go buy another stick of memory, I don't. But maybe you could exchange from the place you bought and say that it was a mistake? The cheapest route without getting the fsb chip to match the fsb of the memory stick is to get PC2700 memory. Have you tried going for this yet? I'm sure that your motherboard may not be shot, my board didn't get shot after trying to the two different fsb. You have to understand, motherboards are picky when it comes to running the hardware. If there is a conflict, it won't run right, I could run at a lower fsb and get it to work fine, but it wasn't at it's full potential, and I wasn't going to waste my time trying to find the fsb that would work correctly. So, I just let my friend have the stick back. This is why I'm asking you to try a lower speed stick of memory, because I have experienced this. But so far you haven't even seemed to notice my replies, could you take a quick overview of what I have said? Sorry if I come off as rude, just I am taking the time to write these replies and really am trying to help from my knowledge base. I have experienced this type of problem of what you are talking about personally.
Ok, so maybe I might not know it all, seeing that other people replying here have the same mb spec and chip fsb and memory like your trying to run, they might know more when it comes to that area for sure, just I didn't have luck trying to run a faster stick of memory compared to my chip, even though my board could run it, I couldn't get it to work, at all. I would just get a black screen, I thought I shot my GPU. Then I reset CMOS and the bios would flash, then when it would start pulling from harddrive, boom, black screen again. I had my friend tinker with my volt. to the right volts of the memory stick, still couldn't get nothing. This is why I am a little skeptical about you being able to run it at all in the long run. Hopefully you can find a way, maybe it is your manufacturer of your stick, but my conclusion is, if it isn't going to work with one, or two of same speed, try lowering it. Like I said, I tried it on this setup right now, and I didn't have to replace the chip or mobo, or gpu, so those should be fine.

System will not boot with Seagate 3Tb expansion drive plugged in.

I have a HP Pavilion HPE h8- 1214 Desktop , I recieved a Seagate 3TB expasion drive as a gift but when plugged in, the system will not boot. It turns on but thats it. It never gets to the boot sequence. I have it plugged into the top 3.0 usb slot and have tried all of the other slots as well with no sucess. But if I leave it unplugged the system boots right up. I can then plug it in and it works fine. I have plugged it into my wifes HP All- In- One and it boots fine and works. I have a WD 2TB drive that works fine as well on my system . I have searched Segates support for hours and all they say is to change the boot sequence. Have tried that, no go. What they dont get is no matter what I do if that drive is plugged in it never gets as far as booting and reading the boot sequence. Please help. Thank you!
