Hello. I just bought a used HP Z640, and was in the initial stages of setting the device up at my home. I started by clearing the CMOS, and reverting any changes by the previous owner of the device in the firmware so I could set things up how I wanted them. I noticed that legacy support was...

Hi, today I was helping my friend upgrade from his 1080 to a 3060ti, we did a Display Driver uninstaller (DDU) After cleaning his pc and installing the new GPU we failed to get a post all the fans turn on and so does the RGB, I have been over the whole pc and all the cables seem to be in...

Hi everyone! My rig seems to randomly restart rapidly in a loop after a few seconds I turn it on, almost like flickering (led flickers along with the sudden fan noise ramps and each lasts between a few hundred milliseconds to a few seconds). Sometimes it successfully loads into Windows before...

Video of the POST LED's: What does this LED ordering mean. Each one coming on, that means its checking that part right? But then it flicks back to the CPU light and powers off. Does this mean that the last LED that was on "BOOT" is the problem, or is it the LED it flicks to that's the problem...

Let me tell the complete story: I have an old Advantech PPC-174T Panel PC. One day I went to install Ubuntu on it, after that the display was totally wrong. I googled and found out that turning off the internal graphics would solve it but I didn't know it hasn't any graphics other than the...

Using a hdmi cable my pc will pass through all the ez debug stages, posting as far as I can tell, just fine but will not output any video to my monitor. On removing the GPU (powercolor RX580 8gb) and putting the hdmi in the motherboard slot, it posts and the boot screen displays. On plugging in...

I am having a lot of trouble with this PC I have. I built it a while ago, and ever since a few weeks after I bought it, I have been having a pretty major and annoying problem getting the thing to even POST. The PC will not boot unless I see the "b2" code appear on the Q-Code readout. This means...

Just to start off, this is an old rig. It's my first computer and I built it in 2014 and haven't changed any internal components since; excepting the addition of two HDDs, one a hand-me-down 70GB Western Digital early on and the other a new 500GB Western Digital within the past 2 years. I have...

I have received a Lenovo Thinkcentre M93p Minitower and after using it for a few seconds it will restart, before spiraling into a constant restarting loop. I have removed the CMOS battery, set the clear CMOS jumper to maintenance mode, unplugged the SSD, swapped RAM. Nothing so far has worked...

I have a computer that I built that worked fine two days ago. I put it in a new case and put a waterblock on the CPU and the GPU. Everything is assembled, and nothing about the system has changed apart from the case and cooling. However now it doesn't work. Dr. Debug just displays a 00 error...

New built computer where I installed the GPU last. With GPU installed there is no video output from either the GPU hdmi and the mobo hdmi. Removing the GPU leads to a normal post with correct video output but the same pattern of EZ debug flashes. Was wondering if I should coninue without the...

Hello everyone. I'm having trouble with the following situation and would really appreciate some input from you guys. Before I start to write the problem, I'd like to mention that I have a Google Docs file with the same question written, but with images showing the configurations and stuff...

hello, I have a Lenovo Thinkpad E550 laptop (win10 x64). I have been using it for many years with no issues. But yesterday when I restarted, the laptop did not boot. Whatever I do on this Lenovo splash screen it will always take me to the "0271: check date and time settings. , Press escape to...

For example, when I turn on the PC in the morning it takes a few seconds for it to post and the bios to load (I can see this because the fans are spinning at max speed and the case LEDs aren't on). After a few seconds (3-5) it posts, fans slowdown and the case lights turn on. If I turn the PC...

First of all, sorry if this post is not made in the correct section. I was cleaning my CPU fan and replacing the thermal paste and now my PC does not boot. I have checked all of the cables including the 24-pin, the 8-pin ATX supply, the 8-pin connected to my GPU and all the small headers such...

tl;dr what can cause no system beep to even happen with no RAM installed?? Let me first sincerely apologize for the title. I’m sure that’s played out here but I simply couldn’t resist. Second, I know this is a long post and really hope it doesn’t deter anyone from taking the time to read it...

So I've been working on my cousins computer for a while and I can't figure out what the issue is. I'll run through everything that was happening, and everything I've done so far. He said his computer one day just went into sleep mode and wouldn't wake up. It eventually got to the point where it...

First time PC builder so I am learning on the job. The PC is pretty much built however I have not yet downloaded Windows, I first wanted to test I could access the BIOS. so my questions is: Even without an operating system should the PC POST every time without fail and the Mobo logo appear on...

Hi All, Last weekend my PC would switch on for approx 6 seconds, shut down then get stuck in an boot loop. Long story short after a few days of testing came to the conclusion the motherboard has failed or is shorting somewhere (nothing has physically changed since it worked fine?) Initially no...

Hello, I have a Lenovo Z50-70 laptop that has been exhibiting strange behaviour for the last year or so. From a powered off state, pressing the power button causes the fan to come on, and the battery, charging and Num Lock lights to come on, but then it sits with a blank screen for anywhere...

Dear users, that's my first post in the forum and I sincerely hope you can give me a hand. I bought a custom build on a well-known online store that I use for work (Simulations and 3D Rendering). These are the main features: Case COOLERMASTER MASTERCASE H500M GAMING CASE Processor (CPU) AMD...

Hi all, As the title says, my system gets stuck during POST, with the BIOS LED on, then shuts down. At first it was the VGA LED that got stuck. After the first time, on reboot it started up seemengly correctly to Windows once, but some of the USB ports and the network (Ethernet) did not work...
