Question about Asrock K7S41GX Motherboard

Motherboard now replaced

Hi Mike, thanks for your previous assistance. I have now put a new motherboard, fan and heat sink in, together with a new PSU with a case fan, (to be on the safe side). However, I am still getting nothing on screen. The CPU is a AMD Athlon XP 2500+. When I felt the heat sink with the PC running it was barely luke warm, (I believe it should be pretty hot!), so I disconnected the fan to try and force the COP to be activated - nothing except a slight humming from the power on button. When I took the CPU out originally I noticed that there was a scorch mark underneath, (is this normal?). Anway I have ordered a refurbed CPU of the same spec to see where we go from here. I have set the FSB on the mobo to the correct setting (333 mhz). I have re-checked all of the wiring and it is as per the board diagram. The board was installed with an anti-static wrist strap so I know it should be OK. I have two memory sticks and have tried them independantly on the basis that both would have failed at the same time. The VGA card has not been instald yet as I wanted to try the on-board graphics first. I have also re-set the CMOS after removing the power lead and PnP items. Thanks once again.

    Thanks Mike, I have now installed the new CPU and..... SUCCESS! The hard drive wouldn't boot so I put the new hard drive in and re-installed XP. However, it would only recognise 128GB of the 160GB available. After installing SP2 and Partition It I was able to merge the unallocated partition. Thanks for all your advice it was much appreciated.

Hi Eagleboy, the odds of two boards having the same problem are something way out there. The only constant is your case, memory & hard drive.
To answer your first question about the CPU being luke warm is (very good)! That is what it should be. Please plug the fan back in. (You said -" When I took the CPU out originally I noticed that there was a scorch mark underneath, (is this normal?)". Yes & No. Every CPU should have either thermal grease or a thermal sticker which helps pull the heat from the processor to the heatsink. Over time if the processor was running hot the thermal sticker most likely withered away which left a scorch mark on the heatsink. A thermal sticker (which is much less messy), is not as good as thermal grease. (My opinion).
Since this is a new board, now would be the perfect time to download the hard drive's utility tools. Find the name of your hard drive & S/N, go to the Mfg's web site & download their setup tools. If you have two hard drives unplug the data cable for the second drive. Create a bootable floppy disk or bootable CD & run the Mfg's diagnoses on the drive. Think back, you mentioned you had formatted your hard drive & the system ran fine. (For awhile).
This seems to be the single connection between the two boards.

It's always suggested to do a fresh install of windows when a new motherboard is installed. So check your hard drive Eagleboy, check it twice & setup once.
Below is the link for your new board. Bookmark it.

Good Luck! Check that drive.

My motherboard keeps on overheating @ 70C and over plz what must i do?

Hello and Welcome to FixYa!

If the overheating is not due to hardware issue, faulty components, you can control the temperature by using Heat sinks and Temperature controlling fans, and by regulating a proper Air flow to the unit. For this, you can also use Cooler Master casing specially designed for high end purposes, or can use any such available brand to control the temperature...

if you did not used heat sink paste between the heat sink and the cpu unit, that, will be you problem initially
the paste is used to exclude any air and gaps between the cpu back and the heat sink and makes a perfect heat transfer medium

Sir, I have a Dell optiplex GX110. At the motherboard there is a long brown slot in which a board of 4 expansion slots has been pluged. The first problem was that I had removed the heat sink from the...

When you inserted a test probe into the slot and you saw a spark, then you have short circuit a component on the motherboard and have done a major damage to the motherboard.
You need a new motherboard, most desktop cases have standard mounting holes, you may be able to purchase a motherboard from other manufacturer to fit in the Dell.

Buzzer sound from motherboard spkr

Hi kuldeep11203, your Intel D101GGC board uses the Award bios.

Though the descriptions vary, I suggest you check your CPU heat-sink & fan assembly. Clean assembly from excessive dust build up. Remove CPU fan if possible & clean the heat-sink. Check the CPU fan, it may be turning too slowly & may need to be replaced. The average CPU fan runs between 2000 Rpm & 3000Rpm. Blow out your power supply with canned air. Disconnect & than re-connect the Main power connector (2x12) on the board. Item No# K, found on page 11 in your manual. Try these first. See if the buzz sound stops after a good cleaning.
If not replace the Heat-sink assemble with a new one. Check this link for a new assembly for LGA775 socket;

Good luck kuldeep11203!

Pentium D problem

Hi oilian,
Be glad it did shut down. If it didn't, your new CPU could haveover heated. There are a few reasons for a CPU to over heat.
1.) There is no thermal grease or too little on the heat-sink assembly.
2.) The old thermal grease was not removed or the old thermal tape was not removed.
3.) The heat-sink assembly was not cleaned completely with alcohol before applying new thermal grease.
4.) The CPU fan is running too slowly.
5.) The heat-sink fins are possibly filled with dust build-up & the CPU fan can not cool the heat-sink assembly. Boot to the bios & go to Hardware Monitor. There you can check voltage, CPU fan speed, CPU temp & other bios monitored settings.

Good luck oilian!

Dell motherboard {GX 270} over heating.


It seems the system is "dying" or already "dead". The initial heat issues suggests a faulty Processor (PRC) Fan. Faulty Power Supply Unit (PSU) Fan can have same effect.

Open the Base unit; disconnect everything (incluiding Keyboard, mouse, network) power-up and check that PRC and PSU fans are working.

Also check the QUAD Pack Diagnostic LEDs and compare the sequence with

This will help with identifying the cause. Try the Dell Suggested Resolution.
