PC is unable to start Windows 7 unless I run WMDT

[royalflush]

Hi. I'll explain my problem as accurate and as comprehensible as I can. I have this weird problem on my pc where I can't start Windows unless I run Windows Memory Diagnostic Tool. My pc will just boot to the page where it says 'press DEL to enter setup, F12 for boot menu' (hereinafter referred to as boot start screen) and after that no 'Starting Windows' will appear, only black screen. I have to press the space bar simultaneously (while boot start screen is showing up) just to get to Windows Boot Manager and pressing tab to go to WMDT (additionally, if I press F8, black screen is all that I get). At first I waited to finish the test but I accidentally press ESC button and bam, the 'Starting Windows' appeared and it started. I don't know what's the root cause of this. I don't want to do that everytime I want to use my computer or restart it. I hope someone can help me know how to resolve this.

P.S: Before I have Windows 7 installed in this pc, I have Windows Vista. I reformatted all disk, delete any partition, made a new partition, and then installed Windows 7. It stuck up on the 'Starting Windows' screen without the logo appearing after the first restart (where there is a countdown or you can choose to manually restart it). I then tried to install it again (making a Windows.old in my pc) and it would stuck up again. I tried the three bootrec.exe commands and it fixed it and I was able to start and complete the installation process. After a few days, the problem stated above started to appear (where I need to go to WMDT just to start Windows). I installed Windows 7 again, formatting every disk. It stuck up again at 'Starting Windows' screen and then I thought 'what if I start WMDT, will the same thing happen?' so I turned my pc off, press space bar many times, tab, WDMT, ESC, and then voila, it started normal and was installed successfully. Please help me solve this. Thanks.

P.P.S: I have a Hitachi Flora 330 DX1 Intel Pentium 4 HT 3.4 GHz. with 2.00 gb RAM. OS is Windows 7 Ultimate Version 6.1.7601 Service Pack 1 Build 7601. Graphics card is Intel 946GZ Express Chipset Family.

P.P.P.S: The said problem did not affected any of my files. When my pc started Windows 7 after I used the said method, all installed programs and other documents was still there. I tried my best to be comprehensible. If there are any confusions, just ask and I'll reword it to make it as clear as possible.

RoyalFlush,
Welcome to SevenForums.

Where did you obtain your Win 7?

Use this procedure to fill out your system specs please:

Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Manufacturer and Model and
ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

You will find that in Speccy, you can select info from the display
using your mouse/touchpad and then paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

I obtained my copy in a retail store here in our country. This is really weird. I've already searched for any similar problems online but still no luck.

Do NOT post your 25 character Product Key!

My question, and the reason for the question, is do you have your 25 characterr Product Key? Should be on the box or container of the the software you purchased.

The key is what you pay for Win 7 can be downloaded, legitimately, from the Internet.

Did you buy a "full" version or an "upgrade" version?

I have a 25 character product key (it's in the container) and I bought a full version.

Pro=actively test your RAM - Test with Memtest86+ for 5-6 passes or overnight to stress it, isolate any bad stick or slot.

Swap sticks, checking slots for debris. Try each stick separately.

RoyalFlush,
That's a rather underpowered computer. I looked up the specs.

Good enough for email and browsing but not much more.

Anyway, after following Greg's advice regarding testing your memory, then perform a clean install.

After the clean install, use MSE, Microsoft Security Essentials. for your AV protection. Link to MSE in my signature.

here's a link to perform a clean install:
Install - Clean Install

I'll do it and report any problems that I'll encounter. Thanks for helping.
