I installed a POS system at a restaurant using 2 rebuilt Dell computers running XP Pro purchased on EBAY. The POS software is registered and made by FREEPOS. i have a problem with station 1 which is also the database server.

 

Station 2 which runs off of the network drive, in this case drive S has had no problems. Station 1/server freezes up during placing an order. The last time it froze it was writing to the database or so it said. The first time it happened i brought station 1 to my office and it sat and worked perfectly for 6 days straight. I took it back to the restaurant and it froze up the first night. I originally had a wireless network between the 2 stations. I sat the 2 stations next to each other and connected both to the network using pre-made cat 5 cables thru the linksys hub and disable wireless completely. They ran fine for one night then station 1 froze up on the second night.

 

When station 1 freezes i have to let it sit turned off for about 15 or 20 minutes before it will boot back up. If i try to boot it too soon it says "hard Failure". To me this would indicate component failure due to heat but I take it to my office and it runs great for six days doesn't back up the component failure theory. I cannot repeat the problem in my office no matter what i do. There is a new UPS in the restaurant so power should not be the issue. Network being short and hard wired should mean network is not the problem. I block the vents in the back of the computer in my office to make it heat up. Where it is installed in the restaurant is cooler than my office.

 

This really has me stumped and is costing me hundreds of dollars not to mention my reputation. Any suggestions will be greatly appreciated.

well this is my opinion but with XP not being supported anymore i think you need new workstations. you dont want to have the restaurant losing anything and being down for a long time because its systems have a virus that cant be controlled

Where did you get this "Freepos" for Windows? The only software that I know by that name is found at Sourceforge: http://sourceforge.net/p/freepos/wiki/Home/, and it is Linux only.

If you have the ability, run a diagnostic test on the hard drive and the memory of the computer in question. The hard drive test I use is MHDD. I will post instructions on how to run the test below this post.

 

Another thing to look for is blown or bulging capacitors on the mainboard or video cards etc examples: https://www.google.com/search?q=blown+or+bulging+capacitors+motherboards&client=firefox-a&hs=ydT&rls=org.mozilla:en-US:official&channel=np&source=lnms&tbm=isch&sa=X&ei=I_JsU-PxKYSHyAT3tYCIBw&ved=0CAkQ_AUoAg&biw=1272&bih=766

 

By the way it might be a power related problem. You could test with a new PSU. ---->  "When station 1 freezes i have to let it sit turned off for about 15 or 20 minutes before it will boot back up. If i try to boot it too soon it says "hard Failure".

If a hard drive has a smart status warning or the drive is questionable this test may be of use NOTE this test does not work with AHCI or Raid sata operation. It must be done with IDE, ATA, or compatibility mode:

 

Before running this test it would be a good idea to backup any data that you cannot afford to lose. This test uses the hard drive at 100%. If the drive is failing or has problems it is possible for the drive to fail suddenly especially during heavy use as this test will do. It is unlikely but still I recommend backing files up to be safe. Here are the instructions to run the test:

 

The first step will be to burn MHDD to a disc as an image (cd preferably). MHDD Can be found here: http://hddguru.com/software/2005.10.02-MHDD/  Click the Last version of MHDD, CDROM iso-image download and burn this file directly to a disc.

 

TO CHANGE SATA OPERATION: (You may need to use your keyboard arrow keys and enter key if you can not click to change settings).

After burning the disc, restart the laptop and start tapping f2 or f1 or delete right away to get into the bios. There you should see System Configuration, expand that by clicking the + button (or using your arrow keys and enter key). In that list there should be something called Sata operation. (Sata Operation may also be by itself in that first screen list)

Click on sata operation and take note of the current setting to the right it will probably be set to AHCI it will need to be switched back to this after MHDD is done running. Select ATA, compatibility or ide mode and then click apply. Save and exit the bios, or if apply was the only option you can use Ctrl+Alt+Delete to restart.

COMMON BOOT MENU/BIOS keys: https://support.fixmestick.com/hc/en-us/articles/201577043-How-to-get-to-your-Boot-Menu-or-your-BIOS-settings

 

Now with the burned disc in the drive after a restart, start tapping (F12 Dell, Toshiba, Lenovo), (F9 HP), or (Esc HP, Samsung, Sony) on the keyboard (or change your boot options to boot to cd/dvd first). This will bring up the boot options menu. Select cd/dvd/cd-rw drive and hit enter.

If this worked correctly and booted to mhdd you should see a screen that says Microsoft windows 98 startup menu. You can let the timer run out or just hit enter on option (2 . Start computer without SCSI support).

 

Now you should see a screen with numbers, most of these will not have any device listed behind them but one number should for example on my dell computer number 6 has WDC WD1600BEVT-75A23T0… and at the end a number in white which is the size of the drive.

Example: If your drive is a 500gb I would expect that number in white to be somewhere around 500,107,862,016 or close to. Find the correct drive to test then on the keyboard type the number in front of the drive (in my case it was 6) and then hit enter.

 

Now you should have a screen with MHDD> and a blinking cursor.

Now hit F4 on the keyboard 2 times and this will start scanning the hard drive.

You should be able to see the computer start scanning, each block represents 255 sectors (130560 bytes) on the hard drive. What we are looking for will show up on the right side of the screen.

There is a list on the right which shows numbers:

<3

<10

<50

<150ms

Etc…

 

Anything below the <150ms is a slow sector or a problem sector. Slow sectors <500 or >500 will slow down the computer. If there are a lot of these one after another (several 1000 or more) the drive should probably be replaced. Also if you have any at the end that were marked as UNC this means the drive has uncorrectable errors and the hard drive should probably be replaced.

Basically if you have any sectors that are below <150 (green) let me know and if possible the total number of them.

 

If all of the sectors were ok and fell within the range of:

<3

<10

<50

<150ms

Then the hard drive is ok, if there are only a few that are slow <500 or >500 the hard drive should be ok to use.

 

NOTE: that if there are many slow sectors one after another or you start having error after error the drive is in bad shape and I recommend ending the test. To end the test hit the Esc key.

 

After you are done testing you will need to go back into the bios by restarting the computer and tapping F2, F1, Delete (or whatever key gets you into bios). Go back to Sata Operation and change it back to the default which probably was AHCI.

Then restart and the computer should boot again.

(If you are getting a blue screen and the computer restarts go back into the bios and confirm that Sata Operation is set to what it was before changing it to IDE, ATA, or compatibility).

 

ADVANCED USERS: (USE AT YOUR OWN RISK)

There are options for fixing drives: erase delays and re-map bad blocks, enabling re-map is ok to do for most drives, no data should be lost. DO NOT erase delays if you have not backed up all of your data! These options are available from the F4 menu (only pushing F4 one time from the MHDD> blinking cursor screen.) Use your arrow keys to move up and down to highlight the option and hit enter to open and change the setting. Another useful key to hit at the MHDD blinking cursor screen is F8, this will bring up a drives S.M.A.R.T information.

 

What re-map does: This option if enabled moves available data from a bad block to a good block and disables the bad block by telling the controller to add it to a black list (list of blocks that the drive will not write to). This is a good option for drives that have available free space that have many bad blocks that can cause many problems including: BSOD bug check 0X7A etc. During a scan with re-map enabled a BLUE block after a bad block indicates succesful re-map.

 

What erase delays does: This option if enabled will erase blocks (and add them to the black list) that are slower than <500ms, if you have a lot of slow sectors greater than 20% of the total blocks, this is not recommended. If you erase delays on an OS drive or drive with any data, your OS may no longer load, your data may become corrupted. I only recommend this option on a drive that you intend to format and then re-use. Erasing delays can speed up a drive. The logic: 500ms = half a second. Each time windows tries to write or read from that block it takes half a second. Having a file written in 1000 slow blocks at 500ms (each block) would cause that file to take 8.7 minutes to read. 1000 blocks = 124.5 Megabytes. During a scan with erase delays enabled a white W indicates an erased slow sector. Slow sectors >500ms can significantly slow down write/reads depending on the actual read/write time for the block.

Hi, A couple of suggestions if the the computers are the same make and model.

 

1. Swap hard drives and see if the problem follows the drive or the computer

2. Contact the seller as to be honest it sounds as if the hardware has a problem.

 

Good Luck

Roger
