My mobo fried tonight.... Need some suggestions

[btbam]

I set my FSB to 225, 220 ran at 43c so I thought what the heck, lets try 225, well I've cleared cmos and the pc still wont getback to bios using xp 2500+.

I had a MSI K7N2 mobo, It was quite nice...

I seen another on newegg for 65 shipped, is newegg a pretty good retailer? Ship fast?

Also, using DDR400 and barton 2500+ and 6800gt oc what other mobo might I look at?

Newegg is very reputable and ships fast. The Abit NF7-S has earned a reputation as one of the best nForce2 boards. On your MSI K7N2, you might try holding down the Insert key before & during power-up after clearing the CMOS and see if that persuades it to come back... never know

yeah, ive discovered that the motherboard is fine, I stuck a 1ghz tbird in, and set to 100fsb, hit power and she booted all teh windows without a problem....

I put the 2500 back in, and YAY it actually started to boot, I saw the first post screen, heard the solo beep, then it shut itself off.

Tried again and shut itself off.

Cpu still shot or is the cheap thermal paste I applied causing a quik overheat?

Check whether your heatsink is mis-positioned: third and fourth photos emphasizing the non-symmetrical nature of the heatsinks. That's the most common reason for an auto-shutdown. Even cheap thermal grease will get the job done short-term, if the heatsink is making flat contact with the CPU core and the heatsink's clip's pressure point is over the core.

More info about your heatsink might help. Sometimes an overloaded power supply will cut power suddenly if it can't handle the load, too... if you want opinions on how suitable your PSU is, post the full system specs and what brand/model of PSU and someone can evaluate that.

If your 2500+ can even get to showing the first POST screen, then it might be damaged but at least it's not truly dead Good luck!

update:

I took enitire setup I used to local Pc store to test on ther e"techAId" Pci diagnostic card.

teh cpu I have was placed in another board, pc powered on and booted fine.

then the pci card diagnostics gave some sort of code relating to bios flash, funny because i flashed bios with live update before this error occured.

the psu used was an Antect smartPower 350, came with new Antec case, I'm replacing that with the enermax 431 true i have here now.

Also, the HSF WAS (ouch) seated improperly before Pc store diagnostic.


The techs there suggested that everything may be fine hardware wise, that the bios might need to be restored....

Please respond, thanks again!

pc fiannly booted on 100fsb jumper, did a suggested bios flash from the website file base, flash was 100% clean but now the pc wont post to any screens at all...


Im over it

If I may ask, what does pressing Insert do?

Does it only work with MSI boards or will it do something on an Asus board?

Many of the AMD boards I've used had the insert key feature. I haven't read any documentation about it, but my practical experience with it is that when the board fails to boot after trying too aggressive of overclock settings, instead of having to clear the CMOS you can just hold down the insert key while powering on and it'll load fail-safe defaults so the system boots and you can correct the settings.
