Specs: Windows 7, 3.0GHZ / 2GB
HI, I've been having the same problem too.My comp restarts every time I play a game .g command and conquer kanes wrath , COD , red alert 3 and many new coming games .Usually takes 10-20 min before it restarts.I've tried everything to fix the problem but nothing seems to work.My video card is Ati readon HD 5450 with 300W PSU and Intel Extreme series board(BX48BT2), Intel Core 2 Duo E8400 3.0GHZ,500GB black caviar,XMS 1333mhz DDR3 ram with heat sink .I don't think the comp's overheating because every thing is cool nothing is hot.If you have any suggestions please post them.thanks.

Hd 5450 isn't gaming card, u need a real gaming card. Check cpu, gpu, system temp and post them here (use gpu z for v-card). Do u have spare psu?

"why do you say that Hd 5450 isn't gaming card???"

Because it's not. It only has 80 stream processors & uses 64-bit DDR2 memory. It's a general purpose / Home Theater card. Sure, you can play some games with it, especially older games like the ones you mentioned. But "many new coming games"? It ain't gonna happen.

The rebooting could be caused by an overloaded power supply, overheating CPU, bad RAM, driver problem. Turn off the "automatically restart" feature & see what happens.

300W isn't much of a power supply these days. If it's a cheapie unit & you're running near max load, it could be causing the reboots. Post the brand name & the amperage specs. If you don't know them, open the case & get them off the label.

"how can ya say that it uses 64-bit DDR2 memory???"

Because you didn't tell us it uses DDR3 until now. Regardless, the HD 5450 is a home theater card, not a gaming card. It only has 80 stream processors - ATI's low end gaming cards have 320 stream processors. You can argue all you want, but those of us who are familiar with modern video cards know that the HD 5450 is NOT good for gaming.

The following link is to a Sapphire HD 5450 w/1GB DDR3 memory, & guess what? It's 64-bit. To the best of my knowledge, there are no HD 5450s that use 128-bit memory - why would it be needed on a card with only 80 stream processors?

"even if i turn off the automatic restart feature the pc still reboots with a sound"

There you go. If the rebooting was caused by a software problem, disabling the automatic restart feature would cause the system to lock up & display a "blue screen of death". That means the problem is most likely hardware related. I don't know what "kKkkKKKKkkkkkk" is supposed to be? If it's a clicking noise then the system shuts down, the problem is probably an overloaded power supply.

"The Brand name for 300W PSU is liteon"

LOL. That unit sells for $7 online - YES, seven dollars! What does that tell you about it's quality? Why would you spend all that money on a CPU, board, RAM, etc, then connect it up to a $7 power supply??

LiteON 300W - $7

Since it was too much trouble for you to post the amperage specs, I'll do it for you:

+3.3V @ 18A, +5V @ 25A, +12V @ 19A.

You definitely need to upgrade the power supply. If that unit blows, it may take out the board & CPU along with it. Get a new one ASAP & make sure it's a good one!

Actually first i had a inno 3d 9600 DDR3 graphic card but some how its fan started to make voice and then it automatically stop running then i took another fan and hooked it on it but after a month the card died then the PSU got busted.then i took this card the 5450 and the 300w PSU.

So ya are telling me that my PC reboots because of the overheating of the PSU?what if i attach a fan next to it so it keeps the PSU cool for the mean time as i am in Pakistan so things are expensive here .What do ya say will this help me or not.

You are rite i should have taken a better PSU in the start but i ran out of money while purchasing all the rest of the parts.

"can ya recommend me a good gaming card?"

You already had one, the Geforce 9600 with DDR3. And it probably died because it was starved for power. Getting a decent power supply should be your priority, not getting another video card. To give you an idea of how much better your old card was, here's a comparison of the 9600GT to the HD5450:

Not only is the 9600GT a MUCH better card, but it consumes 5x as much wattage. Get a new power supply & make it a good one!
