Question about Barebone Systems

Door knob I have a door knob on a room that is loose and I can't figure out how to tighten it. There are no screws on either knob plate, so I can't seem to get it off. I do see in the 1/4 -1/2 inch gap that there are some screws inside the knob. What a puzzle. I have tried just turning it clockwise and counterclockwise and that seems to tighten it but it doesn't stay tight. ANy clues?

Re: door knob

A couple of ideas: Sometimes the top of the knob is a cap which can be levered off with a sharp blade. Or, there is a grub screw (which may need a hex key to turn it) in a hole on the underside of the knob.

HP 4215xi all in one, continues to give the error paper jam, there is no paper jam. I have cleaned all sensors, rollers etc. I have tried a partial and full reset. Any ideas?

  1. Turn off the HP product and turn it around so the back of the unit faces you.
  2. Disconnect the power cord from the back of the all-in-one. The power cord must be disconnected to allow the paper feed rollers to turn freely.
  3. Locate and open the rear access door by pressing in on the left side tab and then pulling the door toward you. Figure 2: Removing the rear access door

Inspect the pressure rollers on the rear access door and verify that they are clean and turn freely. Clean the rollers if needed with a soft towel lightly moistened with water. If the rollers do not turn freely, replace the rear access door. Click How to Buy on this page to order replacement parts.
  1. From the rear access door opening, remove the jammed paper.
  2. Remove the remaining paper from the paper supply tray. Discard any paper that is damaged or crumpled and then re-stack and reload the paper into the paper supply tray.
  3. Reinstall the rear access door.
  4. Reconnect the power cord to the unit and turn the unit on.

The following information will help prevent paper jams from occurring:
  • Never use paper that is torn or wrinkled.
  • If you are having problems using paper that has already been printed on once (recycling), replace it with new paper.
  • Remove and then reinstall the rear access door. Verify that the access door is fully locked in place. The paper can skew if the rear access door is not locked.
  • Every six months to one year, clean the paper feed rollers with a rag lightly moistened with water. Over time the paper feed rollers accumulate dust and do not function as well as they once did.
  • When printing envelopes, tuck the flap into the envelope and crease the folds before printing.

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.

My shuttle hangs up when booting. Both the blue and yellow activity light remain solid and the heat sync next to the cpu seems to get very hot. I have removed all peripherals, pci card and reseated ram and...

It's possible that the CPU is overheating. If you leave it alone for a while, the CPU cools down enough to boot, but will hang shortly because the activity heats it up. When it gets too hot, it won't even start. If you removed the heat pipe/radiator at some point in the past, you were supposed to clean up the old thermal grease and apply some new one. Make sure that your room temperature stay's below the mid 70s. Using the default cooling setup, the CPU can rise in temperature to the 60s (in Celcius) with the fan going all out. The CPU's life could shorten if it operates around 70 and fail around 90. Make sure that all the vents are free from dust for better ventilation. What I did on my XPC was to use 2 fans on the radiator: a quieter one on the inside (80mm?) to push and a larger one (120mm) on the outside to pull. I used a fan adapter to accommodate the larger fan. It was measured no higher than 55oC while playing DOOM3 with fans blowing at minimum speed.

Since installing a GeForce 8400 gs video card, my monitor has had faint flickering lines running across it. They're horizontal if on my native resolution(1440x900) and diagonal if I swap to something...

Sounds like you need to update your driver software, which can be found here: If that doesn't help, then it seems like you have a faulty video card, sorry about that...

I hope this helps!

How to install CPU- Intel Pentium Dual Core E5200 into a asus barebone system P4-P5N9300pc please?

This particular CPU is not on the list of processors supported by this board. See "CPU Support List" tab:

ASUS P4-P5N9300 Spec

How to install Socket LGA 775 CPUs:

Lift up the cpu slot load plate (which covers the pins and also locks the cpu in place) and install the processor slowly, vertically and carefully into the socket without bending any of the tiny pins in the motherboard socket. Lock the load plate.

The advent of the LGA 775 form factor moved the tiny pins from the CPU to the motherboard socket. Great for Intel, not so great for motherboard manufacturers. Now bent pins are the responsibility of the board makers. Customers with bent pin problems are no longer contacting Intel.

Can not find instructions to use the card reader!

G'day mate, I'm not 100% sure but some of the cards such as the MemoryStick Duo come with card reader jackets. The jackets look like memory sticks that have been hollowed out. You place your Memory stick inside the jacket then slide it into the card reader. I had the same problem trying to read a memory stick duo in a PC's card reader but it always seemed way too loose. I can't guarantee anything but have a go and see what happens, the worst is nothing will happen, lol.

How do i open the mbox 2 pro?

There are five shiny screws and one black one located behind the plastic front label (the part that has the markings for the input levels and switches), plus three behind the serial number label, inside the handle part you open with the allen key. This removes the front panel, then, there are about twelve screws around the plastic casing, attaching the casing to the inner metal encasing.

There are three screws behind the foam strip on the metal casing, which attach a heavy duty metal strip to the inner casing... the rest are obvious.

This is how to deconstruct the casing in the event that something is rattling inside.

Keep in mind, if you still have a warranty on your MBOX 2, you won't anymore once you deconstruct it. So I don't advise it unless your device is well past warranty.

Though, if something is indeed rattling inside, I'm sure that's a breach of warranty conditions anyway.
You had best check on that first, but you might end up taking her apart anyway.

Brother MFC-440CN Error 50

The cover on the 440CN is tough to get off. I have removed many. I will tell you that the cable from the scan (black mylar [plastic]) is fragile. I destroyed one of the printers by killing the connector end of the cable. That being said, on the 440 you have to remove the push button panel before the cover. There are 3 screws in the back. The cover then snaps off but feels like you are breaking it and it will snap as it comes off. I did not break this part on any of the printers so.... you should not worry too much. After that there are clips on the front that keep the top cover on. You must release these with a screw driver. You can insert the screw driver and twist. While twisting apply some upward pressure and it will release. You also have to remove a number of connectors, ground wire to get it apart.
