My E4252 shuts down on boot-up> I have tried changing the psu to no avail. If the motherboard is cooked where can i get another?

If VGA is onboard, add a VGA card and see.
If you have a VGA card installed, try replacing it.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((motherboard to your hard drive))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps

replace all leads including IDE and SATA and electrical before replacing a new PSU

You said removed ram but have you tried 1 stick at a time? If its not bad memory it will be the motherboardsorry to say. Cheers from Scott and please dont forget to vote

Choose within this options with regards to your monitor: 1. You could replace your monitor with a new one. 2. Or you could send someone or send it to a technician to repair your monitor.
Boot Up Problem: 1. Try checking the Power Supply Unit (PSU) if it give out 12Voltz. If not you could replace it with new PSU. 2. Check the motherboard if there are some blown out Capacitors. If there is, send it to a technician to replace it. If none, replace your Processor. That is the defective. That causes the boot up problem.
On boot up screen. Of course it will not show a boot up screen because there is a problem on your monitor. And so, there is also a problem on your motherboard (Processor or Capacitor).
Hope this might help. Thanks.

try replacing youre power supply, or if youany spare one use if the result is still the same then you have a motherboard problem, i also have the same problem with mobo, same thing, i already tried using a diff power but there still no boot or any beeping sound,

First try another psu, if it doesnt solve the problem, then the motherboard probably has a serious problem. You may have to change it

Hi,
This could be a hard drive problem. The hard drive is looking for the boot sector on it, but the boot sector is broken. Computer shuts down and tries again but your hard drive can't find the boot sector so it shuts down tries again etc.

Ya. If it keeps re-booting then it may be a virus (my things virus)
If not, go to system properties and start up and recovery settings. remove reboot on error settings (in XP) It doesnt fix the root cause but may stop your frustration

The best advice I can give you is to remove the motherboard battery (UNPLUG THE PSU BEFORE YOU WORK ON THE MOTHERBOARD) and let the system sit for about an hour. If the CMOS settings are corrupted, removing the battery will erase the corrupted data in the CMOS, which will automatically reset the CMOS to the default settings... Then, plug the battery back into the motherboard, and try to boot the system...

If that doesn't work, you should disconnect EVERYTHING attached to the PSU, and remove ALL of the add-in cards (modem, NIC, soundcard, TV tuner, whatever you have), and install ONLY the CPU, the heatsink/fan (don't forget to PLUG THE CPU FAN IN), ONE stick of RAM... you get the idea. DISCONNECT the HDD, the FDD, the optical drive, and ANYTHING ELSE from the PSU. When you're ready to test the system, you should have ONLY the CPU, the HSF, and one DIMM plugged into the motherboard. Attach the PSU connectors (both the main ATX connector AND the auxiliary 4-pin 12-volt connector) to the motherboard, and try to boot the system. If it works, SHUT DOWN and UNPLUG THE PSU; then install ONE component (the floppy drive, for example), reattach the PSU, and reboot the system. If the system POSTs, shut down, unplug, and add another device. If the system does NOT complete the POST process, the last piece of hardware you installed is probably the culprit.

Take your time with this; be methodical, and make GOOD notes about the steps you've followed, so we can help you work through this problem...

Best of luck to you; keep us "posted" on your progress...
