Compatible memory for the MACH SPEED P4MSD-800D2

you will not get all 4gb because the flash drive has to format and setup instruction the drive will only be about 3.86gb not 4gb

Firstly, what (if anything) did you change in terms of hardware or software recently? If you have can you tell me what it was and how you did it. Have you tried overclocking it?

You should be able to fix this simply by restoring your default BIOS settings. If this fails, then let me know and i will get back to you
If the above doesn't work, try updating your BIOS to the newest available. If you give me your motherboard manufacturer and model i can find a suitable BIOS upgrade for you.

If still no hope then the problem may be with your CMOS battery. So, try leaving your computer on for some time and put the battery back and try. Also check the battery if it is dead replace it with new one same type. If these do not work the problem may even be with your system fan.

Remove the little watch type battery from the mother board check the voltage with a meter should be about 3.5 volts. Then replace the battery on the mother board. This battery holds memory within the Bio chips on the mother board, if there was a problem that it sensed for turn on it will be in the Bio's memory, and maybe not allowing the computer to turn on, by removing the battery for a few minutes, the Bio's forget they had a problem, if you will. and the computer might turn on.
If you have all the voltages to the mother board from the power supply, it should turn on.
unless there is some reset circuit interfearing with it turning on. Or you might have a blown fuse on the mother board, I would check everything I could, and try everything I could, and if you still cannot get it to turn on take it to a computer shop and spend a few bucks for them to fix it.

is the fan prosessor running if yes try to cleanup the memory if doesnt work change the memory

It sounds like something isnt working right, what operating system are you using, Vista? I would take out the original 512 and see what it says after, often ram isnt compatible if it is too different in size and speeds. Also, if your motherboard supports dual channel ram and you have the extra 512 chip it wont run in dual channel mode, you would run better with just the 2 chips then the added 512 chip.

Hi a_car, I understand your trouble. Mach Speed shows little information about the bios settings. The fastest way to get the bios to load the onboard graphics would be to clear the cmos jumper. This is shown on page 12. JCMOS1: Clear CMOS Header. Do not forget to set the jumper back to normal. If this fails to load the onboard graphics card I'll try & guide you from memory.
Enter the bios. Go to the title Advanced. Within advanced menu look for, advanced chipset features & integrated peripherals. One or both should list the settings you want to change too. When using the onboard graphics card, you will also need to set the total amount of system memory you want the graphics to use.

Good luck a_car!
Thank you for using fixya.
Merry xmiss!

Here is the information you will need.
http://www.shopping.com/xPF-MACH-SPEED-MB-VENOM-V2DP

just refer to your motherboard manual which is given to you at the time of purchase of the motherboard.. it will be clearly given with the pin numbers to connect the front panel or back panel audio ....

thank you
bye
any doubts you can reply me
i am always here to assist you
rate my solution ....

Hi dwman113,
Yes your Mach Speed MB will support 2x1 GB, Dual Channel Mode DDR2-800MHz, PC6400 memory modules. (Manual states the memory dimms should be paired).
Also known as matched memory.
Max Shared Video Memory is 256MB, refers only to the integrated built in video card.
Click this link to help you understand what CL stands for; http://www.hardwaresecrets.com/article/26/3
Small example. CL3 runs faster than CL5.
You can run any PCI-Express 16x graphics card & it can be rev 2.0. Graphics cards are backwards compatible which means it will also run at v1.0. You should not buy a SLI card because you only have 1 PCI-E x16 slot. To run SLI, (Hooking up 2 PCI-E x16 cards together viva a small SLI connector) your motherboard would need two PCI-E x16 slots & the board must support SLI mode & your's does not. Here is the main web site link for your Mach Speed MSA2-6100V MB.

If you have any more issues or questions just post it & we'll go from there.

Good luck dwman113!

I had the same problem once. I took it to CompUSA to have them diagnose the problem, and they said I fried the motherboard or CPU. The fans turn on just because your power supply is on.
