Posted: 7/22/2008 8:36:43 AM EDT

I had a problem with my computer rebooting. I reformatted it and clean all the dust out of the case. It stioll is doing it.

what could be causing it to keep rebooting?
i am about ready to throw it out the door and go buy a new one.

HP with Xp installed.

Did you install SP2 on a non-legit copy of Windows XP?

is it bluescreening then autorebooting before you see the bluescreen? disable autoreboot on a bluescreen.

edit: start / settings / control panel click system click advanced tab click settings under startup and recovery then unclick autorestart

edit again: if thats the case you will see the bluescreen next time it happens and you will be able to find out what is causing the problem.

Sounds like a possible hardware problem. First and easiest thing I would check is the memory. You can download software that will test it or you could temporarily swap it out with some from a different system and see if your problem goes away.

Make sure your cpu fan is spinning and check the cpu temp to see if it is what it should be, try reseating the ram. Does it reboot if you just stay in the BIOS or just when booting windows?

Check your CPU and Memory

bad ram (use memtest)
bad hard drive (use manufacturer specific testing software)
bad capacitors on the mobo (visual inspection should be enough to spot the culprits)
bad power supply (need PSU tester)
bad heat-sink-fan on the cpu (run prime number generator)
bad thermal compound bonding between cpu and heatsink (unseat heat sink fan combo and inspect. if you don't know what you are doing here, i would suggest getting some help. don't want to put a screwdriver through your mobo)
bad drivers (make sure you get all the updated drivers from the internet)

need to check all of these first before coming to any conclusions.

if you have access to another computer try burning a copy of the ultimate boot cd to run most diagnostics outside of windows.

Lots of hardware issues can cause this. Video card drawing too much power, power supply going bad, motherboard going bad, bad RAM.

don't know how to do some of those.
probably would be cheaper to replace the tower than take it to a repair place

Could be a lot of things. We had one do that a lot, only to find out the UPS we had it plugged into was blinking the power.

At least try the memory test. Microsoft has a free one if I remember correctly.

when you boot do you hear any beeps? do you hear fans running? can you even get to the windows screen before the reboot? what kind of computer is it? can you get to your bios at all?

all these questions need to be answered so you can get a good idea whats up. the suggestions that have been posted are good ones by the way. check them all out.
personally i would check the ram. unseat it one at a time and reboot with one out. see what happens there. if it reboots and allows you to perform normal operations you have 1 of 2 things wrong. you have a bad stick of ram or you have a bad channel on your board. power down and try to move the ram into another channel.

HP a510ecan you get to your bios at all?should beable to

It hasn't did a reboot in the last 30 mins - 1 hour see what happens there. if it reboots and allows you to perform normal operations you have 1 of 2 things wrong. you have a bad stick of ram or you have a bad channel on your board. power down and try to move the ram into another channel.
