If cleaning the heads using the cleaning tape did not help, then there are 3 possibilities that I know of:

1) The heads are sufficiently dirty to require direct cleaning with a more powerful solution.
2) The heads are defective.
3) The heads are out of alignment.

Parity errors are not usually controller problems. If the head alignment has drifted enough, you may be missing a track when recording. An initialization includes writing format information at the beginning of the tape. This is "re-read" during the process to confirm correct writing. This is the part that is failing.

Keep me posted.

Have an error message on screen sayng NO HDD???


The system does give this message when the logic board can't access the Hard Disk.
Can be anything, from a complete over filled HD till a defect controller or just a corrupted first sector. Check what the user manual says about initialise the hard disk. If that won't help, consult a tech close to you. Btw. after an initialise or format you will have lost everything you recorded till now. So if something important is on the disk, ask a tech to get out the drive and recover the important stuff. This could cost you.

Parity Check 2 error on startup


If it hangs at this point then it is likely you have a bad or mis-seated memory board. If you are confident to open your PC the first thing to try is re-seating all of your memory strips (boards). You can look at your model manual to see what they look like and where they are in your PC, but short of that look for 1 or 2 rows of very short boards mounted on the motherboard. Depending on how much memory you have you could have from 1 - 8 of these little boards.

**Note, always remove the power plug from your PC before putting your hands inside, while there are no lethal voltages it is easy to damage the PC if it is powered while you mess around inside.

** Take great care inside your PC, cables can be easily bumped ajar or knocked completely off what they connect to.

The first thing to try is to just push on each one, do not remove them, using both hands, push down on the two corners of each of the boards, and try to rock them a bit, pressure on left, then right, then both.

If this does not help, then next you want to remove all of the memory boards, and make sure to carefully mark what slot you removed them from and which way they are plugged in, which way the chips are facing.

If you have 2 or more you need to try them in pairs, if you have just one then you need to go buy a replacement, BestBuy has them or if you can wait order one from Amazon.

Either way you need one known good spare to troubleshoot.

If reseating by pushing does not work, remove them all and put them back in exactly where you pulled them from and try to power up again.

If this does not fix it then remove them all again and take the a pair or single if there was only one, and swap one of them for the new memory you bought, plug them in, and power up. If it works then the one you swapped out of the bad one, if not, then try the next two, any two will do but put them in the next available slot.

If you put in a pair in these steps and the parity error pops up then one of the last two you put in is bad. Swap one and try again if it is good then the bad one is in your hand, if not, swap the one out for the last one. If it is still broken then there is more wrong.

Good Luck.

Dell Optiplex 330,won't boot memory parity error, tried new bios battery, new ram stick, still won't boot,actually had two at same time the other I ran a advanced diagnostic test said hard driv


I found this

Customer's Optiplex 330 did the same thing today; no beep codes (due to lack of on board speaker). Solid/orange light on front of case indicates board or cpu. I isolated every component not soldered down (RAM, HDD, Optical, etc). Considering all the fans and lights on the MoBo were functioning, and no physical damage to the CPU was apparent, and the BSOD presented the "memory parity error; system halted" (meaning it's memory, graphics memory, or cpu and we've eliminated possibly CPU and RAM) my conclusion is that the problem resides in Graphics memory failure. Considering the error message is very vague and generally insists "motherboard", the gpu in an optiplex 330 is integrated ON the board, lumping it all together.

and general memory parity fail information

Memory parity 2000


Hi Kelly, we are dealing with memory problem, if you have available memory try swapping it, the other way is to remove any card attached in *********** board that may cause some conflict with the system, Isolate 1 by 1 the hardware installed from your hardware.
1. remove the memory module, clean the tip of the memory, the one connecting to the slot with rubber eraser or any rubber. If possible swap with good one if you have to isolate memory defects.
2. remove/clean any cards(video cards and others) in your expansion slots.
3. Boot your PC without connecting the hard/CD/FDD drives to speed up checking.
4. Once start up is okay without memory parity error appearing, one by one install the Harddisk, CD and FFD.

Can not reinstall os on mt acer 246lc it bleeps 4 times and swithes off


Without knowing what motherboard is in the unit - it will be difficult to determine what the 4 beeps means.

Generally, 4 beeps means issues with :

- memory
- video card
- keyboard
- motherboard failure

Things to try -

- make sure there is no keys stuck down
- remove the battery and AC adapter, remove and re-install the memory sticks (reseating the memory)

If this does not work, your problem may be more serious. Let us know the results of the above suggestions.
