Computer will not boot!


Recommended Posts

Okay. So I put together a new computer consisting of an ASRock H55M-LE motherboard, an intel core i5 660, a 500W power supply, and 4GB of corsair 1333 DDR3 memory. I put it together, and it doesn't work. Nothing happens other than the fans spinning and the hard drive. I have reseated the RAM in every possible combination (6 of them) and even tried reseating the CPU. The motherboard uses the GPU that is in the core i5, but I get nothing displayed through the VGA or DVI ports. What am I doing wrong?

Thanks.

First of all... 6 ram chips on an H55?

Are you getting a post beep (if you have a speaker on your motherboard), if not i dont think you seated the ram correctly. Try only using 1 module in the computer and make sure clips on both ends are inside the groove on each side of the module.

Just use one stick of RAM to test to get rid of any other possibilities with the RAM sticks.

Other than that, do you have a power supply tester?

+1

You need to simplify things to begin the process of elimination.

Right now it could be 1 of about 5 things.

Oh yeah.... RTFM !

I have 2 ram slots meaning that there are 6 different combinations I could have with RAM in the motherboard. I plugged a chassis speaker into the speaker pins on the motherboard but have not gotten a beep even with no RAM in the motherboard. The CPU I bought was open box, so hopefully that was not the problem (it was their last one). All power connections are in the motherboard correctly, and hopefully the chassis speaker is as well (although I have tried it in both orientations). Would it be the motherboard or the CPU that would be the problem here?

Thanks.

Ok so you have disconnected everything unnecessary for a POST? Leaving only the mainboard connected with 1 stick of RAM left in, moving that stick around slots each power cycle ?

No HDD, DVD, FANS, PCI, PCI-e Cards or any other device should be connected while troubleshooting the board, and connected to the PSU should only be the board

Disconnect SATA / IDE / USB / Front Panel (Except power switch)

Remove CMOS battery and try a boot without that in

Some boards require 2 x 4Pin CPU power leads (Mine spins fans but wont POST with only 1 x 4PIN)

Ensure you are not shorting the back of the board onto the chassis

try this:

check if the motherboard speaker is connected

1: remove all ram. this should make a beep telling you that there is no RAM

2: remove CPU. this should make a beep.

if none of the above make a beep code then is you motherboard or power supply.

Removing the CPU would make a beep ?

Dont know about that, maybe if you removed it while it was powered on it might lool

+1,

Yea - if you will remove the CPU while the cmputer is powered on you might see a big BEEEP in your head from the power that will drive in you like a car on a highway.

Sadly, none of these things worked. No beep from the speaker, and no output to the screen once I eventually started trying that.

Well if you have troubleshooted it with a barebone system, you can put it down to the mainboard or the CPU, and in my experience, it is 99% always the mainboard

Do you have another PSU to test ?

Well I just looked at the ASRock website, and it says that it has support for the C2 version of my cpu, and with a BIOS upgrade, the K0 version. The problem is, I don't know which version I have, or even how to upgrade the BIOS when it won't POST. I Also do not have another PSU.

Read the instructions on ASrocks site. Some have Floppy options, if you have that.

My experience with computers that won't boot, but power on. It's usually a motherboard issue. If you don't get a post with one or no sticks of RAM in, that's not good. It should at least beep multiples times.

Ah if it is infact that your BIOS does not support that CPU yet, then you have no option other than to put in a CPU that it does support, Update the BIOS, and then replace your CPU

I reckon your Motherboard is shorting against the case. Try removing the motherboard from the case and turning it on laying on your desk. I know it sounds unusual and maybe even implausible but I've had this happen before. I'd hit the power button and the system would turn on but nothing on video out, no beeps, no real life in the system just the fans spinning. I took it outside of the case, worked perfect. Put it back, died again. Eventually after looking at the case I realized that the 'risers' (which was just pressed metal and not real screw-in risers) were shorting the board from the back.

I think the CPU not being supported is also a likely cause but I'd expect you to receive at-least a beep of some kind in that event. Just like if there was an issue with the memory or the graphics.

Yea or at least run at the wrong speeds

Problem resolved. I originally bought a case for $35, and it came with a 500 W PSU. I got a new one, and problem solved. Thanks for the help though.

What size did you end up getting? a 500W wasn't enough, wow.

    • Microsoft finally admits its default Windows 11 25H2, 24H2 action broke key legacy component by Sayan Sen Microsoft last week released Windows 11 KB5094126 and KB5093998 as the latest Patch Tuesday updates. Following that the company also published the accompanying dynamic updates under KB5094149, KB5095971, and KB5094156. So far the company has acknowledged two known issues that have popped up after the release which include bugged-out Office apps as well as the Recycle Bin; though there could be more at play too. Speaking of bugs and issues, Microsoft seems to have finally acknowledged a problem that probably has been around for close to a year. That's because back in July of 2025 the company made a default change to the latest Windows 11 versions, wherein it switched to JScript9Legacy on Windows 11 24H2 and later releases. Hence following the release of version 25H2 in October 2025, JScript9Legacy also remained default-enabled. As a result there has been a compatibility issue ever since then. For those wondering, by switching to JScript9Legacy Microsoft intended to improve the security of modern Windows PCs by reducing vulnerabilities tied to legacy scripting like cross-site scripting (XSS), among others. XSS exploits can allow cyber-attackers to attach malicious code onto legitimate websites and use them to execute the code when a potential victim loads such a website. Hence the new JScript9Legacy engine enforced stricter execution policies and improved object handling, which should help mitigate such attacks. Microsoft today has published a new support article detailing the problem. Neowin spotted it while browsing. The company says that JScript global definitions and execution context may fail to persist across scripts, potentially breaking older dependent apps and web-based components that relied on this legacy behavior. In the article Microsoft has confirmed that the issue stems from its move away from the older jscript9.dll engine in favor of jscript9legacy.dll. As mentioned above, while the newer engine was designed to address vulnerabilities and strengthen security it also changes how JScript handles execution context. As a result functions and definitions loaded by one script could no longer remain available to subsequent scripts once execution ended. The company notes that some applications worked correctly on earlier Windows versions because the older JScript engine automatically retained global definitions and execution state between scripts. Under the newer model though that behavior is disabled by default causing certain legacy workloads and polyfill-dependent scripts to fail. Microsoft says it addressed the problem via the KB5077241 update though the fix had not been enabled automatically in the following updates. As such admins must explicitly turn on persistent JScript execution context using a Registry setting that the tech giant shared today. The configuration can be applied to individual processes or system-wide through the FEATURE_ENABLE_PERSISTENCE registry key. The steps have been outlined below: Run the following command to create the feature control registry key: reg add "HKLM\Software\Policies\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_ENABLE_PERSISTENCE" Under this key, create a new DWORD (32-bit) value. Configure the value as follows: To enable persistence for specific processes only: Set the value to 1 for each target process name. To enable persistence for all processes: Add * as the key name and set its value to 1. You can find the official support article here on Microsoft's website.

    • VidCoder 12.20 by Razvan Serea  VidCoder is a DVD/Blu-ray ripping and video transcoding application for Windows. It uses HandBrake as its encoding engine. Calling directly into the HandBrake library gives it a more rich UI than the official HandBrake Windows GUI. VidCoder can rip DVDs but does not defeat the CSS encryption found in most commercial DVDs. You’ll need the NET 8 Desktop Runtime. If you don’t have it, VidCoder will prompt you to download and install it. The Portable version is self-contained and does not require any .NET Runtime to be installed. You do not need to install HandBrake for VidCoder to work. Feature list: Multi-threaded MP4, MKV containers Completely integrated encoding pipeline: everything is in one process and no huge intermediate temporary files H.264, H.265, MPEG-4, MPEG-2, VP8, Theora video Hardware-accelerated encoding with AMD VCE, Nvidia NVENC and Intel QuickSync AAC, MP3, Vorbis, AC3, FLAC audio encoding and AAC/AC3/MP3/DTS/DTS-HD passthrough Target bitrate, size or quality for video 2-pass encoding Decomb, detelecine, deinterlace, rotate, reflect, chroma smooth, colorspace filters Powerful batch encoding with simultaneous encodes Customizable Pickers to automatically pick audio and subtitle tracks, destination, titles and more Instant source previews Creates small encoded preview clips Pause, resume encoding VidCoder 12.20 changes: Updated HandBrake core to 1.11.2.
