Windows 7: Computer will not post.

This has been going on for quite a while. Problem started with getting BSOD several seconds after bootup. Booted to safe mode, and tried to use Restore. Got message that there are no restore points set? Tried to use Repair to no avail. Booted original Windows disc and tried repair from there to no avail. The tried Imaging which ran for several hours, and then message that Imagining Failed. Then No Post. After reading numerous messages on-line, decided to RMA the MB and the PSU. Installed these items, and still no post. HDD led flashes off and on. Ancillary fans run. CPU fan starts, does a few revs, and stops. Beginning to suspect the CPU? Maybe someone has some ideas? This computer ran outstanding for a couple years before the trouble.

can u boot into windows?

CPUs typically don't die unless you are overclocking them past what they can handle. It's more likely the HDD or memory. Memory could be a possibility, but you could get a bootable Memtest disc to find out. Same with the HDD...a bootable HDD testing tool from the manufacturer would give you an answer.

as you turn you pc on, where the post is suposto be press the button you would use to access Bios, look for any thinsg wrong there

First, since the computer will not post, I cannot boot Windows, nor can I access the BIOS. During post, I don't even get to the Splash Screen. Since I can't post, I also cannot use a disk to check memory or use a drive. Also, from another site, I understand that you can post without any drives attached. In that mode, you can post, and then add these items back one at a time to find the bad one. I previously disconnected all of the USB, Hard and Optical drives, and tried to post with just the Motherboard, Power Supply, CPU, Graphics card, and Memory. Since I've replaced the Motherboard, and Power Supply, this seems to drill down to the CPU, the Memory, or the Graphic Card. All of these items are still under warranty, so maybe I just start requesting more RMA,s. Also, from another site, I understand that you can feel the CPU to see if it is heating up. It's cold, but I don't know if that's it's problem or that something else may be causing.

If you have access to spare parts, try substitution, rather than just requesting replacement of the parts. You only have to have "some" RAM to boot, so if you have more than one stick, you can try each one individually to see if either will boot.
You're not likely to have, or find, a spare CPU, but maybe you have an old video card on the shelf, or a friend who has one, that you can use for testing purposes. Same with RAM sticks. Even a low density stick would allow you to test by substitution.

Almost forgot, remove your CMOS battery and let the BIOS reset too. Doesn't hurt, even if it doesn't help.

The motherboard has a 2 digit led array and you can see what's being displayed and look up the error code.

Well by the sound of I would guess memory.

Here's my diagnostic steps:
1. Use the clear CMOS button on the back
2. Memory, pull it and boot, wait for beeps (Newegg people love Gskill, I wouldn't touch the stuff) Make sure you use dimm slot 1 and 2 for only 2 sticks.
3. Drain all power (pull plug hold power button for 3 seconds), Use the power button on the motherboard
4. Make sure you have 8 pin cpu power, grab a multimeter, and check voltages. If you need to power it on use a paper clip on green and any black, will fire up the power supply for testing.
5. Replace ram with 1 cheap stick of DDR3-1066
6. Make sure all standoffs are used and no incorrect ones are up against the motherboard.
7. Swap CPU
8. And not really a step, pay more, and buy intel and never buy MSI.

But yeah, check for error codes.

Randall it's nice you have such strong opinions but in the end it's only yours. MSI and GSkill is top flight kit.

Of course, it's an opinion, but lets not turn this from a help thread to something else, along with my opinions come years of PC diagnostics turned into a quick diagnostics how to. Along with those years comes plenty of systems with MSI and Gskill in them.

I hope my opinion based step 2 and 8 aren't the only value taken from my post.

So lets keep this on topic, not about me or you?
