Question about Jetway MiniQ 765Twin (miniq765twin) Barebone

1 Answer

Blank screen and never starts.

My jetway is never starting up at all. I moved Memory, cooler and CPU from a functional unit so there schould be no problem with those. It just never starts.... still the LCD is working. I have also tried to install a new AGP video card and the screen is still blank when starting up.

I can not tell when this started since I just got it myself and the previous owner claims it works. The CPU I am trying to use is an AMD Athlon 1900.

I cant overclock my system but i go to bios now whati had to do

The BIOS. Overclocking is best done in the computer's BIOS (Basic Input/Output System or Binary Integrated Operating System). There are also some motherboards that let you do a basic increase in power by setting a jumper, but this is dangerous and you have no real stability control.

There are some software programs available which allow you to overclock inside the operating system, but the best results are achieved by changing BIOS settings. Usually you can get into your BIOS by pressing DEL (some systems may use F2, F10, or Ctrl-Enter) as soon as your computer begins the POST

(Power On Self Test - when it shows the RAM size, processor speed, etc.).

Here, you can change your FSB (front side bus), memory timings, and your CPU multiplier (also referred to as CPU Clock Ratio).

Clearing your CMOS. Sometimes, an overclock can become unstable. If this happens, or your computer will not boot, you will need to reset the BIOS back to default and start over again.

This is done by clearing the CMOS (a small piece of memory on the motherboard which stores your BIOS configuration, and is powered by a small battery). Some newer motherboards will bypass user settings in the CMOS if the computer fails POST (often caused by a faulty overclock). However, most motherboards require a manual clear.

This can be done in two ways, depending on your motherboard. The first way is by changing the position of the clear CMOS jumper on your motherboard, waiting a few minutes, then repositioning the jumper to its original place.

The CMOS Jumper

The second way, if your motherboard doesn't have this jumper, consists of unplugging your computer, removing the little CMOS battery, then pressing the power button (your capacitors will discharge), and waiting a couple of minutes.

Then you have to refit the battery and plug in your computer. Once your CMOS is cleared, all BIOS settings are reset back to default and you'll have to start the overclocking process all over again. Just so you know, this step is only necessary if your overclock becomes unstable.

Locked or Unlocked. The first thing to know when you start the process of overclocking, is whether your processor is multiplier locked or unlocked.

To check whether your CPU is locked, lower your multiplier via the BIOS one step, for example from 11 to 10.5. Save and exit your BIOS and your computer will restart.

If your computer posts again and shows the new CPU speed, it means your CPU is unlocked. However, if your computer failed to post (screen remains black) or no CPU speed change is present, this means your multiplier is locked

Multiplier Unlocked Processors. Usually, your max overclock is limited by your memory, or RAM. A good starting place is to find the top memory bus speed in which your memory can handle while keeping it in sync with the FSB. To check this, lower your CPU multiplier some steps (from 11 to 9, for example) and increase your FSB a few notches (e.g.: 200 MHz to 205 MHz).

After this, save and exit your BIOS. There are a few ways to test for stability.

If you make it into Windows, that is a good start. You can try running a few CPU / RAM intensive programs to stress these components. Some good examples are SiSoft Sandra, Prime95, Orthos, 3DMark 2006 and Folding@Home.

You may also choose to run a program outside of Windows, such as Memtest. Load a copy of Memtest onto a bootable floppy, then insert the disk after you have exited the BIOS.

Continue to increase your FSB until Memtest starts reporting errors. When this happens, you can try to increase the voltage supplied to your memory.

Do note that increasing voltages may shorten the life span of your memory. Also, another option is to loosen the timings on the memory (more on this a bit later). The previous FSB setting before the error will be your max FSB. Your max FSB will fully depend on what memory you have installed. Quality, name-brand memory will work best for overclocking.

Now that you know your max FSB, you'll figure out your max multiplier. Keeping your FSB @ stock, you raise your multiplier one step at a time. Each time you restart, check for system stability. As mentioned above, one good way to do this is by running Prime95.

If it doesn't post (reread the section about clearing the CMOS), or Prime 95 fails, you can try to raise the core voltage a bit. Increasing it may or may not increase stability. On the other hand, the temperature will also be increased. If you are going to increase the core voltage, you should keep an eye on temperatures, at least for a few minutes.

Also note that increasing voltages may shorten the life span of your CPU, not to mention void your warranty. When your computer is no longer stable at a given multiplier setting, lower your multiplier one step and take that as your max multiplier.

Now that you have your max FSB speed and your max multiplier, you can play around and determine the best settings for your system. Do note that having a higher FSB overclock as opposed to a higher multiplier will have a greater impact on overall system performance.

hope this helps

Constant BSOD when cold

bluescreen can be caused by a number of things

a bad driver loose or faulty lead or not having enough ram

click start control panel administration tools computer management device manager scroll through all of your devices

if you see a yellow question or exclamation mark ? ! or a red X you will need to update the drivers for this device right click select update driver/reinstall driver

if you can see your usb device but its not working scroll to Ports(Com&Ltd) right click to update driver

if you computer came with a motherboard disk the drivers could be on it

or you might have to download one

you might not have enough RAM random access memory not having enough will cause your computer to run over its maximum limits and can cause the blue screen of death and hang and cause memory dumps

make sure your ram modules have a dust free secure seating and the CPU central processing unit has thermal paste
if you dont want to install more ram uninstall some unnecessary programs

a bad or faulty motherboard lead or its connection if its a flat 40 pin ide it will be the first to fail
make sure all leads have a dust free secure connections

hope it helps

Where is the CMOS reset jumper or battery on Jetway JBC600C99352W-BW Mini-top. Can not find CMOS reset or CMOS battery. Any help?

I am not sure you have the exact model I do, but the battery is on the underside of the motherboard - you must undo the four silver screws holding the board down, and also two screws to remove the front plate. Pull the board up and out, and you will see the battery underneath.

Impossible to boot after changing BIOS settings. No BIOS reset jumber No removable battery Nothing in the documentation. How can I reset the BIOS of thie computer ? Thanks,

If not even the pressing of the Del key during POST brings the BIOS screen then you will have to dismantle the unit, disconnect the SDD and try to boot like that. If it fails even now then the BIOS has been corrupted beyond repair - you will have to send the unit for repair - a dealer or the manufactured will have to reload a new BIOS at a hardware level, with special tools and software.

Motherboard no display problem. i clean my motherboard, and tried by changing CMOS battery also. but there is still NO DISLPLAY. please help me..

I would guess that your video adapter (possibly part of the motherboard) is not functioning. You can add an adapter in one of the available slots if you wish to keep that motherboard.
This is the most likely solution.
One thing you need to try before buying a new motherboard is to disconnect everything but the CPU, memory, and keyboard. Now start it and see if you get a display. If not, your motherboard is probably bad.

My MSI computer won't startup. It has an

It appears that you have only checked the power supply and the on/off button. There are many reasons a computer won't start.
These are only two. Have you "stripped down" the system? This means removing everything but the CPU, Memory, and video card. If it starts with only these things attached, then you can rule out the mainboard, memory, and video.
Next remove the memory. If it starts but you get memory error beeps, then it could be one of the memory modules.
After all that, you can then figure it's the mainboard or the CPU.
As for circuit diagram, I would think these would be very hard to find.
