W98se reboots continuously

By delboy51 ·
I run a number of NEC PCs (600Mhz 128Mb RAM). One of them has begun to reboot continuously - so it would start normally, load Windows and show the desktop as usual, then after a few seconds the screen clears and the whole process starts again, and again, etc. Can boot in SAFE mode and have run disk check and defrag.
Suspected a virus or spyware and ran Sophos in SAFE mode - nothing.
Eventually reinstalled Windows. Now it still does the same except it restarts when the first 'New hardware found' is reached.
Tried substituting components from another NEC machine but the fault is always present on the original one. BIOS settings are also identical.
In summary the PC with only W98 installed (can't load drivers or apps)continually reboots.
Help - any ideas?

usually when a PC will run in safe mode but not normal mode, it is a driver issue. Other possibilities are adware/spyware and memory. Since you reinstalled Win98, we can assume adware/spyware is not the issue leaving driver and memory as likely candidates.

If you only booted up in safe mode and did not allow to run for a reasonable period, cannot really infer anything from that either.

If that's the case we are left with memory, power supply, and mobo as likely culprits. Check mobo for deformed (bulging) or leaking capacitors. If caps are bad so is mobo. Change out power supply and memory and test.

Happy hunting.

Thanks for suggestions
1. Certainly the PC will run in safe mode >30 minutes.
2. Substituted both memory and power supply from identical PC without any change to the symptoms. In fact I have stripped the machine to its bare essentials, ie PS, system board, HD, FD, to elimate other periperals - no change.
Any more ideas?

Number one sounds good.
Memory is a particulary bad one to track down. If you have more than one stick installed try it with just one at a time.
You can download a free, good memory tester at www.simmtester.com, called DocMemory Diagnostics.
It determined that a brand new 512MB was bad, sent it back even though they insisted it was good and they confirmed that it was bad.

Reread original response and you will see that I believe it is a driver issue if PC will run in safe mode.

Most probable culprit is video driver. Install VGA driver while in safe mode and see if system is then stable. Could also be other hardware that doesn't play nice with Win 98 default drivers. May be trial and error until you find the bad actor.

Also try a step-by-step confirmation start, if not already attempted. Don't really think it will reveal anything in this case, but doesn't hurt to see.

Since PC is unstable, you probably haven't installed system specific drivers. Need to do so as soon as you can after getting it to boot in normal mode.

Please reread my original message where I make the point that the the PC has only W98se loaded so therefore only default drivers (VGA driver I suppose) and as CD drive is inactive it's difficult to load drivers! I thought safe mode only used basic default drivers. My suspect now is the system board, although it doesn't explain why safe mode works!

You cannot assume that VGA driver was loaded. Win98 has support for many video cards builtin. Also cannot assume that it is not another driver.

Try cleaning or replacinfg the CPU fan, although it may look like running properly. This worked wonders with me.
If a virus is suspected and cannot find it, try a clean install of windows; delete the window and program files folders and install (no need to format)
